Product Details
As a lobby aluminum door manufacturer, DERCHI builds its doors around thermally broken 6063-T5 aluminum profiles with polyamide thermal breaks and multi-layer EPDM seals. Insulated double-glazed units—typically 8mm+21A+8mm argon-filled—reduce energy loss and noise. Upgrades to Low-E, laminated, or triple glazing are available for demanding commercial lobby doors.
Unlike off-the-shelf products, these custom aluminum lobby doors are sized per project, with frame thickness from 2.5mm to 5.0mm and leaf gauge up to 3.0mm. Pivot, hinged, or hidden hinge styles accommodate manual and automatic operation. For hotel lobby aluminum doors or office building entrance doors, engineering covers wind pressure and thermal insulation. Shop drawings and installation guidance are provided for B2B projects.
Product Features
Thermal Performance: Thermally broken profiles and argon-filled double glazing deliver high insulating values. This structure helps hotel lobby aluminum doors maintain indoor comfort and reduce HVAC costs in commercial settings.
Acoustic Comfort: Multi-layer EPDM seals and laminated glass options significantly reduce external noise. Essential for office building entrance doors overlooking busy streets.
Robust Security: Multi-point locks, shootbolts, and optional smart locks with fingerprint or card access secure every entrance. Designed to meet the demands of commercial lobby doors.
Durable Finishes: Powder coating, PVDF, and wood grain finishes resist weathering and corrosion. Available in custom RAL colors to match architectural styles for commercial lobby doors.
Design Flexibility: Custom aluminum lobby doors come in pivot, hinged, and hidden hinge styles, with sidelites and transoms. Adaptable to any entrance layout for hotels, offices, and apartments.
Smart Integration: Compatibility with automatic door openers and smart access systems simplifies traffic flow. Ideal for modern office building entrance doors requiring touchless entry.
Customizable Styles
Glass options include Low-E, tinted, laminated, and reflective types in double or triple glazing to meet energy codes for custom aluminum lobby doors.
Frame finishes from powder coating, PVDF, or wood grain transfer are available in RAL colors, giving designers full control over the entrance aesthetic.
Door sizes and configurations are project-specific; pivot, hinged, or hidden hinge styles can be combined with fixed sidelites and transoms for larger openings.
Threshold types can be adapted for ADA compliance or high water tightness, depending on the lobby design and weather exposure.
Custom aluminum lobby doors can integrate with access control systems, magnetic contacts, and automatic openers specified during the shop drawing phase.
Hardware Accessories
Heavy-duty multi-point locks and shootbolts secure the door at multiple points, essential for commercial lobby doors with frequent use and security demands.
Smart lock options with fingerprint, password, and IC card access offer touchless entry; response time under 0.5 seconds for quick passage.
304 stainless steel handles resist corrosion and are available in lever or pull styles, including ADA-compliant designs for inclusive access.
Automatic door openers can transform lobby doors into hands-free pass-throughs, supporting high-traffic hotel and office lobbies efficiently.
Roller-cam mechanisms and adjustable hinges ensure smooth, quiet operation, while EPDM gaskets maintain seal integrity over time.
Basic Parameters
Performance Item | Available Information | Buyer Notes |
|---|---|---|
Thermal Insulation | U-factor approximately 0.38 on W-Z3 model with argon-filled double glazing | Final U-factor depends on door size, glass, and threshold design. Request project-specific test report. |
Wind Pressure Resistance | 5 kPa tested on W-Z3 configuration | Larger doors or different glazing may alter results; confirm with engineering calculations. |
Water Tightness | 700 Pa under laboratory conditions | Installed performance may differ; request test data for actual door system and installation. |
Air Tightness | 1.2 m³/(m·h) on W-Z3 | Depends on seal integrity and correct installation; ask for field test data if required by spec. |
Sound Insulation | 35 dB measured on W-Z3 | Laminated or asymmetric glass can improve sound reduction; confirm with acoustic consultant. |

Application Scenarios
Apartment: Apartment lobbies benefit from secure, thermally insulated aluminum doors that reduce hallway noise and energy loss while offering a welcoming aesthetic for residents and guests.
Home Office: A custom aluminum entrance with smart lock integration gives home offices a professional, secure front door that blends residential comfort with commercial-grade durability.
Hotel: Hotel lobby aluminum doors must handle high traffic and maintain an impressive entrance. DERCHI’s designs combine robust hardware, wide openings, and acoustic glazing for guest comfort.
Office Building: Office building entrance doors need durability, accessibility, and energy efficiency. Our doors accommodate automatic openers and ADA thresholds, supporting smooth daily flow.
Outdoor: When a lobby door faces external weather, water tightness and wind pressure ratings must be verified. Confirm that the selected glass, frame finish, and seals suit the local climate.
Residential Building: In residential towers, lobby doors enhance security with multi-point locking and add curb appeal with custom finishes that match the building’s architecture.
Exterior: Exterior lobby doors face direct sun, rain, and wind. Buyers should request test reports for water penetration and structural performance specific to the project’s exposure conditions.
Villa: Luxury villa entrances use oversized aluminum doors with bespoke finishes and glass to create a dramatic first impression while ensuring security and insulation.
