The Aluminum Bifold Door For Construction Projects from DERCHI is a custom-engineered opening system built to project specifications, not stock dimensions. Each order is produced based on architectural drawings, opening sizes, and performance requirements, offering flexibility across multiple thermal break series and glazing options.
- Project-specific manufacturing from architectural drawings, covering size, glass, finish, hardware, and opening method.
- Choice of 78, 80, 93 Series or fully custom configurations, with double or triple glazing including Low‑E and laminated glass.
- Factory-direct supply with engineering calculations and multi-certification documentation for construction projects.
Product Details
The system is fabricated from 6063‑T5 aluminum profiles with thermal break technology, EPDM rubber seals, and insulation strips (BAIYUNYILE). This combination supports wide openings while managing thermal transfer and air leakage—critical for modern building envelopes. Double‑tempered glass with argon filling, available across all series, further reduces U‑values and helps meet local energy codes.
Unlike standard folding doors, this project aluminum door system is engineered around heavy‑duty rollers, concealed multi‑point locks, and hidden hinges. Every order receives project‑specific wind load and U‑value calculations, ensuring the selected series, glass makeup, and frame dimensions are validated for the intended structure. The result is a durable, weather‑resistant facade that integrates with commercial and residential schemes without forcing generic product limitations.
Product Features
Verified Thermal Performance: 93 Series achieves U‑Factor 0.28 US/I‑P, helping large openings meet energy codes when paired with argon‑filled double glazing.
Engineered Wind Load Resistance: With wind pressure ratings up to 4.5 kPa (93 Series) and calculated wind load reports, the system suits mid‑rise and exposed sites.
Multi‑Point Locking Security: Up to 4‑side 6‑point locks, anti‑lift protection, and heavy‑duty rollers deliver reliable daily operation in high‑traffic construction environments.
Durable Surface Finishes: Powder coating, anodized wood grain, and PVDF finishes resist fading and corrosion, reducing long‑term maintenance for project owners.
Flexible Glass Makeups: Double tempered, triple, laminated, Low‑E, reflective, and tinted glass options let architects balance daylight, privacy, and solar control.
Project Support Package: Shop drawings, structural calculations, and remote installation guidance are provided, streamlining the specification and site workflow for bulk orders.
Customizable Styles
Panel Sizes: Typical single panel widths range from 500 mm to 850 mm; heights up to 3 800 mm (93 Series) accommodate floor‑to‑ceiling openings in large‑scale projects.
Glass Options: Double tempered (5+27A+5 with argon), triple, Low‑E, laminated, and tinted glass can be specified to meet thermal, acoustic, and safety requirements.
Color & Finish: Powder coat, anodized wood grain, and PVDF finishes are available in sample colors like caramel coffee, dark coffee, black crystal, quartz grey, star black, and black skin.
Opening Configuration: Inward or outward folding, single‑side stack, center split, and up to 10 panels create adaptable layouts for any architectural plan.
Frame Cladding: Optional cladding widths of 47 mm, 70 mm, 75 mm, and 100 mm allow the custom aluminum folding doors to match surrounding facade details.
Hardware Accessories
Handle Sets: KERSSENBERG and CMECH lever handles, including an ADA‑compliant option, deliver ergonomic operation suited for commercial bifold doors and frequent use.
Heavy‑Duty Rollers: Engineered rollers carry each panel smoothly, even after thousands of cycles, reducing site callbacks in high‑traffic project entrances.
Multi‑Point Locks: Up to 4‑side 6‑point locking with concealed rods and anti‑lift devices secures wide openings without compromising clean sightlines.
Concealed Hinges: Hidden hinges maintain a minimalist appearance while providing the strength needed for tall, heavy panels in construction door systems.
EPDM Seals & Flyscreen: Continuous EPDM rubber gaskets ensure air and water tightness; an optional integrated folding flyscreen can be added for ventilated spaces.
Basic Parameters
Performance Item | Available Information | Buyer Notes |
|---|---|---|
Thermal Insulation | 93 Series U‑Factor 0.28 US/I‑P (5+27A+5 argon) | Values depend on glass and frame configuration; request project‑specific U‑value and SHGC calculations. |
Wind Pressure Resistance | 93 Series 4.5 kPa; 78 Series up to 5000 Pa | Wind load reports are generated per project. Coastal or high‑rise sites require location‑specific analysis. |
Water Tightness | 93 Series 450 Pa; 78 Series 500–700 Pa | Static pressure rating; driving rain performance should be confirmed with drainage design details. |
Air Tightness | 93 Series 1.8 m³/(m·h); 80 Series Level 6 | Actual air leakage is influenced by installation quality; site testing may be arranged on request. |
Sound Insulation | 93 Series 30 dB; 78 Series Rw 35–40 dB | Higher STC targets may require laminated or triple glazing. Final acoustic reports available for selected glass makeup. |

Application Scenarios
Apartment: Balcony enclosures and loggia transformations benefit from the slim sightlines and thermal break, turning small outdoor spaces into usable year‑round interiors.
Home Office: An interior aluminum folding door separates a work area from living space without blocking natural light, creating a flexible partition that can open fully when needed.
Hotel: Lobby entrances, poolside suites, and restaurant storefronts use commercial bifold doors to merge indoor and outdoor zones, enhancing guest experience and usable floor area.
Office Building: Meeting rooms and collaborative areas employ multi‑panel folding doors to quickly reconfigure floor plans, supporting agile workplace designs in new construction or fit‑outs.
Outdoor: Terrace connections require weather‑resistant finishes and drainage; buyers should confirm water tightness and wind pressure ratings for the specific exposure level of the site.
Residential Building: Common area facades, community lounges, or entrance links often specify an aluminum bifold door for construction projects to achieve full‑width passive ventilation.
Exterior: Street‑front storefronts or building entrances demand tested air and water performance. Confirm the selected series meets local structural and weather codes before ordering.
