36 inch exterior door

Product Details

The DERCHI W-Z3 Pivot Door is an aluminum pivot entry door built for projects where entrance performance and visual presence matter equally. Unlike conventional hinged doors that rely on visible frames and standard hardware, the W-Z3 uses a concealed pivot mechanism hidden within the top and bottom of the door panel, allowing the door to rotate horizontally on a central axis. This design eliminates the need for traditional side hinges and floor tracks, resulting in a clean, minimal aesthetic that also removes trip hazards at the threshold — a practical consideration for high-traffic commercial entrances and accessibility-conscious residential projects.

The door's structural integrity comes from a combination of a 3.0mm thick door leaf profile and pin-injected glue corner joint technology. Standard screw-assembled frames can develop gaps over time under repeated stress and weather exposure, but the W-Z3's pin-injected glue method creates a chemically bonded connection at each corner. Sealant then fills the 45-degree joints, building a rigid, water-resistant connection that also delivers a seamless visual corner appearance. For buyers evaluating long-term durability, this assembly method represents a measurable step up from conventional mechanical fastening.

Energy performance is addressed through a thermal break structure within the aluminum profile, which interrupts the conductive path that would otherwise transfer heat through the frame. Combined with 8mm+21A+8mm double tempered glass filled with argon gas, the system achieves a verified U-Factor of 0.38 and SHGC of 0.22. These figures position the W-Z3 as a strong candidate for projects subject to energy code compliance requirements. Buyers should confirm with DERCHI that the reported performance values apply to their specific size configuration and glass selection, as actual field performance may vary with dimensions.

The sealing system employs multi-layer EPDM rubber strips that form a continuous barrier around the frame perimeter, blocking air drafts and noise infiltration. This multi-layer approach, combined with the argon-filled glass unit, contributes to the door's verified 35 dB sound insulation rating and 1.2 m³/(m·h) air tightness performance. For projects in noisy urban environments or regions with extreme weather cycles, these sealing details can significantly impact occupant comfort and energy costs over the building's lifecycle.

Product Features

• Impact-Resistant Double Tempered Glass System: The W-Z3 uses an 8mm + 21A + 8mm double tempered glass configuration with a 21mm argon-filled spacer between the panes. Tempered glass provides significantly greater impact resistance compared to annealed glass, reducing the risk of breakage from accidental impacts or severe weather debris. The 21mm argon gas layer between the glass panes acts as an insulating barrier, reducing heat transfer and contributing to the door's 0.38 U-Factor and 35 dB sound insulation. PVDF-coated black aluminum spacers separate the glass panes, resisting corrosion and providing a unified edge finish. Buyers specifying glass for projects in high-wind or impact zones should confirm with DERCHI whether additional glass laminations or configurations are available to meet local code requirements.

• Heavy-Duty Aluminum Door Leaf Profile: The 3.0mm door leaf profile thickness provides structural rigidity that resists sagging and deformation over time — a critical concern for large-format pivot doors that place significant weight loads on their pivot points. Unlike thinner profiles that may flex or warp under wind pressure or thermal cycling, the 3.0mm profile maintains frame alignment and smooth operation throughout the door's service life. The frame profile measures 2.5mm in thickness with a 129mm frame width. A thermal break structure within the aluminum profile interrupts conductive heat transfer, improving overall energy efficiency. Buyers evaluating this door for oversized or non-standard openings should confirm with DERCHI that the 3.0mm profile adequately supports their specific dimensions without additional reinforcement.

• Pin-Injected Glue Corner Joint Technology: Instead of relying on standard mechanical screws that can loosen over time, the W-Z3 frame uses pin-injected glue technology at each corner joint. This method injects adhesive into machined pin holes, creating a chemical bond that distributes stress evenly across the joint rather than concentrating it at screw points. Sealant then fills the 45-degree mitered joints, building a rigid, watertight connection that also produces a seamless corner appearance. For B2B buyers, this construction method translates to fewer field service calls related to corner separation, water infiltration at joints, or visible gaps — common failure points in screw-assembled aluminum door frames, particularly in climates with wide temperature swings.

• Concealed Pivot Hardware System: The pivot hardware is fully hidden within the top and bottom of the door panel, eliminating visible hinges, pivot arms, or floor plates that would interrupt the door's clean lines. This concealed design serves both aesthetic and functional purposes: it creates the architectural minimalism that designers often specify for contemporary entryways, and it removes floor-level trip hazards associated with traditional threshold-mounted hardware. The system supports both off-center and center pivot installation, giving architects flexibility to position the pivot point for optimal traffic flow, spatial planning, or visual effect. Buyers should confirm the specific pivot hardware load rating and cycle life with DERCHI to ensure it meets the traffic demands of their project type.

• Multi-Layer EPDM Sealing System: EPDM rubber strips form a multi-layer barrier around the entire frame perimeter, creating overlapping seals that block air infiltration, water penetration, and noise transmission. Unlike single-seal designs that can develop gaps as the door settles or as sealing material ages, the multi-layer approach maintains performance even if one seal line degrades. EPDM rubber offers strong resistance to UV exposure, ozone, and temperature extremes, making it suitable for exterior door applications across diverse climate zones. Buyers replacing doors in buildings with existing air leakage or noise complaints should consider how this multi-layer sealing approach addresses those specific problems compared to single-seal alternatives.

• Flexible Pivot Installation Options: The W-Z3 system supports both off-center and center pivot installation methods, allowing project teams to choose the configuration that best suits their spatial and design requirements. Off-center pivots create a wider clear opening on one side of the doorway, which can be advantageous for moving furniture or equipment through the entrance, or for directing foot traffic in a specific direction. Center pivots create a symmetrical opening that works well for grand entrance statements where visual balance is the priority. Buyers should discuss their specific opening size, traffic patterns, and aesthetic goals with DERCHI to determine which pivot configuration delivers the best result for their project.

Customizable Styles

• Glass Options: The standard glass configuration for the W-Z3 is 8mm+21A+8mm double tempered glass with argon gas fill and PVDF aluminum spacers. This configuration balances thermal performance, acoustic control, and impact resistance for typical exterior door applications. However, project requirements may vary — for example, buildings in hurricane-prone regions may require laminated glass for impact resistance, while projects targeting passive house standards may need triple glazing with low-E coatings. Buyers should confirm available glass upgrades, including laminated, low-E, tinted, or triple-glazed options, directly with DERCHI during the specification phase to ensure the selected glass package meets both performance targets and local building code requirements.

• Frame Options: The W-Z3 uses an aluminum frame with a thermal break structure, available with a 129mm frame width and 2.5mm frame profile thickness. The thermal break is essential for exterior applications where temperature differential between interior and exterior surfaces can cause condensation, energy loss, and discomfort near the entrance. Aluminum frames without thermal breaks are generally unsuitable for exterior use in climates with significant heating or cooling demands. Buyers should confirm with DERCHI whether additional frame depth options, profile shapes, or thermal break specifications are available to match their project's structural requirements and local energy code compliance targets.

• Size Options: While the product title references a 36 inch exterior door, specific size ranges and custom dimension capabilities should be confirmed directly with DERCHI. Pivot doors can accommodate large format openings that exceed standard door dimensions, but the structural requirements increase with size — making the 3.0mm door leaf profile and pin-injected glue joints particularly relevant for oversized configurations. Buyers should provide their exact rough opening dimensions, structural load requirements, and any clearance constraints when requesting a quotation to ensure accurate manufacturing and proper field installation.

• Color and Finish Options: Specific color and finish options for the W-Z3 aluminum frame are not listed in the current product specifications and should be confirmed with DERCHI prior to ordering. Aluminum doors typically offer a range of powder-coated or anodized finishes that affect both aesthetics and long-term durability. PVDF surface treatments, already used on the glass spacers, may also be available for the frame to provide enhanced UV resistance and color retention in exterior exposures. Buyers with specific color matching requirements — such as coordinating with existing building elements or corporate identity standards — should request color samples and confirm availability during the specification process.

• Pivot Configuration: The W-Z3 supports both off-center and center pivot installation, and this choice significantly impacts the door's spatial behavior and visual character. Off-center pivots position the rotation axis closer to one side of the door, creating an asymmetric opening that can be tailored to the room's circulation pattern. Center pivots place the axis at the midpoint, producing a balanced, symmetrical rotation that is often specified for grand entryways and statement entrances. Buyers should consider their project's traffic flow, furniture movement requirements, and design intent when selecting a pivot configuration, and should confirm with DERCHI any dimensional constraints or structural considerations associated with each option.

• Project Customization: DERCHI indicates the availability of customized central axis accessories for the pivot hardware, suggesting that the W-Z3 can be adapted to meet specific project requirements beyond standard configurations. Customization may include pivot point positioning, hardware finish matching, glass specification changes, or frame profile adjustments. For large-scale commercial projects or architecturally driven residential developments, the ability to customize the door system to exact specifications can be a deciding factor. Buyers should present their full project requirements — including drawings, performance specifications, and aesthetic goals — to DERCHI's technical team to explore available customization options and confirm feasibility.

Hardware Accessories

• Pivot Hardware: The W-Z3 uses customized central axis accessories that are concealed within the top and bottom of the door panel. This concealed design eliminates visible pivot arms and floor plates, contributing to the door's minimalist aesthetic while also removing threshold-level trip hazards. The pivot mechanism allows the door to rotate horizontally on its axis, supporting smooth operation even for large, heavy door panels. Because pivot doors carry their full weight on the top and bottom pivot points rather than distributing it along a hinge side, the quality and precision of these central axis components directly affect long-term operational smoothness and alignment stability. Buyers should confirm the specific load rating, cycle life, and adjustment capabilities of the pivot hardware with DERCHI, particularly for high-traffic commercial applications.

• Handle: The W-Z3 is equipped with a Guangqi handle featuring an integrated armrest design. The integrated armrest provides a comfortable grip surface that spans a broader area than a standard pull handle, making it easier to operate the door — particularly important for pivot doors, which can require more force to initiate movement than lightweight hinged doors. Guangqi is a recognized hardware brand in the door industry, and its inclusion suggests a focus on functional reliability. Buyers should confirm handle finish options, backset dimensions, and whether alternative handle styles or brands are available to match their project's design language and user requirements.

• Soft-Close / Buffer System: Information about a dedicated soft-close or buffer mechanism is not specified in the current product documentation. Pivot doors, due to their size and weight, can generate significant momentum when swinging, and some form of damping or speed control may be desirable — particularly in residential settings or high-traffic commercial entrances where uncontrolled door movement could pose a safety risk. Buyers should confirm with DERCHI whether the W-Z3 includes or can be equipped with a soft-close mechanism, door stop, or speed controller as part of the pivot hardware system or as an add-on accessory.

• Lock System: Specific lock type, brand, and security grade information is not provided in the current product specifications. For an exterior door application, the lock system is a critical component that directly affects building security, insurance compliance, and occupant safety. Buyers should confirm with DERCHI what locking options are available for the W-Z3, including cylinder types, multipoint locking mechanisms, electronic access compatibility, and whether the lock system meets relevant security standards for their target market. The concealed pivot design may also influence the lock placement and mechanism type, so early coordination with DERCHI's technical team is recommended.

• Track System: The W-Z3 pivot door does not use a floor track system, as the door panel rotates on a vertical axis supported by concealed top and bottom pivot points. This trackless design is one of the system's key advantages: it eliminates threshold obstructions that can impede wheelchair access, trap debris, or create tripping hazards. However, the absence of a floor track means that the pivot points must carry the entire door weight and resist all lateral forces from wind pressure and user operation. Buyers should confirm that the structural mounting surfaces at the header and floor can support the concentrated loads transmitted through the pivot hardware, and should request DERCHI's installation guidelines for substrate preparation requirements.

• Sealing and Connection Hardware: The W-Z3 uses EPDM rubber strips as its primary sealing material, arranged in a multi-layer configuration around the frame perimeter. EPDM (ethylene propylene diene monomer) rubber is widely specified in exterior door and window systems for its resistance to UV degradation, ozone attack, and temperature extremes — properties that make it suitable for long-term exterior exposure without the cracking or hardening that can affect other elastomers over time. The multi-layer arrangement provides redundant sealing: if one strip develops a gap due to settlement or wear, the adjacent layers continue to block air and water infiltration. Buyers should confirm the specific EPDM grade and replacement availability with DERCHI for long-term maintenance planning.

Over this period, the company has built a global distribution network spanning 100 countries through 700 distributors, indicating sustained market confidence and product acceptance across diverse regions and building cultures. DERCHI holds 100 national patents for invention and design, supported by a dedicated team of 20 R&D experts who develop and refine pivot door technology. For B2B buyers, this track record provides a degree of confidence that the manufacturer has the institutional knowledge and technical capability to support complex commercial and residential projects, rather than being a new market entrant without proven production stability.

• Factory Capability: DERCHI operates a 70,000 square meter factory alongside a 4,000 square meter showroom. The factory scale supports large-volume production runs and complex custom orders without the capacity constraints that smaller workshops may face. The showroom allows visiting buyers and project teams to inspect finished products, test hardware operation, and evaluate build quality before committing to a purchase. For architects and contractors planning site visits during the procurement process, the ability to examine full-size door assemblies in person can provide valuable confirmation of finish quality, hardware feel, and construction detail that catalog images cannot fully convey.

• Production Capacity: DERCHI produces 600,000 square meters of doors annually, indicating a manufacturing throughput that can support both large-scale commercial projects and ongoing distributor replenishment orders. For buyers managing multi-phase construction programs or recurring procurement schedules, production capacity is a critical factor — a manufacturer that cannot deliver on schedule can delay entire project timelines. Buyers with volume commitments or phased delivery requirements should confirm current production scheduling and capacity allocation with DERCHI during the quotation process.

• Certifications: The W-Z3 holds certifications from NFRC, CE, AS2047, and CSA, covering major markets including North America, Europe, and Australia. The factory operates under ISO9001 quality management certification. However, certification applicability can vary by product configuration, size, and target market. Buyers should confirm whether the required certification documents apply to their selected product configuration and destination market, and should request copies of relevant test reports and certification certificates during the procurement process to support local code compliance and building approval submissions.

• Service Capability: DERCHI's network of 700 distributors across 100 countries provides localized support for project coordination, delivery logistics, and after-sales service. For international buyers, having a distributor in their region can simplify customs processing, provide local technical support, and reduce lead times for replacement parts or service requests. Buyers should confirm the availability and capability of DERCHI's distributor network in their specific geography, and should clarify the division of responsibility between the factory and the local distributor for technical support, warranty claims, and installation assistance.

• Customization Capability: The W-Z3 system offers customization through configurable pivot positions (off-center or center), customized central axis accessories, and what DERCHI describes as project-specific adaptations. For architects and developers who need to match specific design requirements — whether that involves non-standard dimensions, particular hardware selections, or performance enhancements — the availability of customization can be a deciding factor. Buyers should present their complete specification requirements to DERCHI early in the design process to confirm what customizations are feasible, what the cost implications are, and how customization affects production lead time.

• B2B Support: Every W-Z3 Pivot door undergoes a 100% full inspection before leaving the DERCHI facility, which means each unit is individually verified against quality criteria rather than relying on statistical batch sampling. This full-inspection approach reduces the risk of receiving defective units and the associated project delays caused by field replacements. For large commercial orders where installation crews are scheduled and delays are costly, this level of outgoing quality control provides meaningful risk mitigation. Buyers should confirm the specific inspection criteria and documentation provided with each shipment, including whether inspection reports or certificates of conformance accompany the delivery.

Application Scenarios

• Apartment: In multi-family residential buildings, the main entrance door serves as the primary boundary between shared circulation spaces and private living areas. The W-Z3 pivot door's 35 dB sound insulation helps reduce noise transmission from hallways, lobbies, and street-level sources into individual apartment units, contributing to resident comfort and satisfaction. The concealed pivot hardware creates a clean, modern entrance aesthetic that appeals to developers targeting design-conscious renters or buyers. The thermal break structure and 0.38 U-Factor help meet energy code requirements for the building envelope, which is increasingly important as residential energy standards become more stringent. Developers should confirm the door's fire rating capabilities and whether additional configurations are available to meet specific compartmentation requirements in multi-family construction.

• Home Office: Professionals working from home require a physical and acoustic separation between their workspace and household activity. The W-Z3's 35 dB sound insulation helps block domestic noise — conversations, television, kitchen sounds — from disrupting focused work, while the double tempered glass allows natural light to enter the office space, reducing the need for artificial lighting during the day. The pivot door's smooth operation and integrated armrest handle make it easy to open and close throughout the day as the user transitions between work and home life. Buyers converting existing spaces into home offices should confirm that the pivot door's opening arc fits within the available floor area without conflicting with furniture or built-in elements.

• Hotel: Hotel entrances — whether at the main building entry, conference room dividers, or suite partitions — must balance durability, aesthetics, and guest experience. The W-Z3's 3.0mm door leaf profile and pin-injected glue corner joints provide the structural rigidity needed to withstand the repeated opening cycles typical of hospitality environments. The concealed pivot hardware delivers the refined, minimalist aesthetic that upscale hotel brands often specify, while the thermal break and EPDM sealing ensure that lobby areas maintain comfortable temperatures and quiet conditions regardless of exterior weather. Hotel developers should confirm the door's performance in their specific climate zone and discuss available finishes that align with their interior design standards.

• Office Building: Commercial office buildings require entrance systems that manage heavy foot traffic, present a professional image, and contribute to the building's energy performance. The W-Z3's 5 kPa wind pressure resistance and 700 Pa water tightness rating ensure reliable operation during storms that could otherwise force building managers to restrict entrance use. The off-center pivot option allows architects to design entryways that direct visitor flow toward reception areas, while the center pivot option can create balanced, symmetrical openings for boardrooms or executive offices. Building managers should confirm the door's compatibility with access control systems and whether hardware provisions for electronic locks or card readers are available.

• Outdoor: For outdoor or exterior-related projects, buyers should confirm weather resistance, water tightness, wind pressure requirements, surface finish durability, and installation conditions before ordering. The W-Z3's 700 Pa water tightness rating and 5 kPa wind pressure resistance indicate capability for exposed exterior installations, but actual performance depends on installation quality, substrate conditions, and local weather severity. The PVDF-coated aluminum spacers resist corrosion, and the EPDM sealing system maintains flexibility across temperature extremes — both relevant considerations for outdoor exposure. Buyers planning outdoor installations should discuss additional weatherproofing measures, overhang requirements, and maintenance recommendations with DERCHI.

• Residential Building: In residential construction, the front door is both a security boundary and a design statement. The W-Z3 pivot door's large glass area allows natural light to enter the home's entry hall, creating an inviting first impression while the 35 dB sound insulation keeps street noise outside. The thermal break structure and argon-filled glass help maintain interior comfort, reducing cold drafts near the entrance during winter and heat gain during summer. The absence of a floor track removes a common tripping hazard at the threshold, which is particularly relevant for homes with young children or elderly residents. Builders should confirm available sizes, finishes, and lock options to coordinate with their standard door specifications and design packages.

• Exterior: As an exterior door, the W-Z3 faces the full range of environmental stresses: wind pressure, rain, UV exposure, and temperature extremes. The verified performance parameters — 5 kPa wind resistance, 700 Pa water tightness, 0.38 U-Factor, and thermal break structure — address these challenges directly. The pin-injected glue corner joints and sealant-filled 45-degree connections prevent water infiltration at the most vulnerable points in the frame assembly. PVDF-coated spacers resist the corrosion that can degrade uninsulated glass edges in exterior applications. For exterior installations, buyers should confirm that their specific size and configuration maintains the published performance ratings, and should verify compliance with local building codes for exterior door assemblies.

• Villa: Luxury villas often feature grand entrance doors that serve as a focal point of the home's architectural design. The W-Z3 pivot door's full-glass construction, concealed hardware, and minimal frame profile align with the contemporary aesthetic that many high-end residential projects demand. The pivot mechanism allows the door to operate smoothly even at large dimensions, creating a dramatic entrance experience. The thermal break and argon-filled glass ensure that the villa's climate-controlled interior is not compromised by the extensive glass area. The 35 dB acoustic rating is particularly valuable for villas located in busy suburban areas or near waterfronts where outdoor noise can diminish the sense of privacy and tranquility. Developers and architects should confirm available customizations for handle design, glass tints, and frame finishes to coordinate with the villa's overall design language.
