DERCHI is a Foshan-based manufacturer of exterior aluminum doors, serving project buyers worldwide from a 70,000 sqm facility. Our product line includes pivot entry doors, sliding and bifold patio doors, and heavy-duty large sliding systems—all built with thermal break aluminum profiles. Key strengths:
- Profiles that deliver low U-Factors and real energy savings
- A full range of opening styles: pivot, swing, sliding, bifold, folding
- Project-specific dimensions, glass, finishes, and hardware
- End-to-end support from shop drawings to export shipping
Product Details
Each exterior aluminum door system from DERCHI starts with 6063-T5 aluminum profiles and thermal break technology—polyamide strips separate inner and outer frame sections to reduce heat transfer. This separation is critical for meeting energy codes like ASHRAE 90.1. We seal double or triple glazing (including argon-filled and Low-E options) with EPDM gaskets and integrated drainage to maintain air and water performance. The product range covers multiple configurations: the W-Z3 pivot door uses concealed hardware for a grand entrance; the P103 swing door delivers secure inswing, outswing, double, or French-door layouts; the Q15 heavy sliding door handles panels up to 4000 mm wide and 6000 mm high; and 5-panel bifold doors open inward or outward for seamless indoor-outdoor transitions. All series can be tailored in size, glass, and finish to fit residential, commercial, or hospitality work.
Product Features
U-Factors down to 0.38 are achieved with thermal break frames and argon-filled insulated glass, cutting heating and cooling loads in multi-family and commercial applications.
Multi-point and four-side six-point locking systems secure entry doors without cluttering the design or compromising smooth operation.
Sliding panels up to 4000 mm wide open up daylight and views in retail, hotel, and residential settings, while still delivering strong thermal performance.
Pivot doors with concealed hinges and central axis hardware provide flush sightlines, giving architects a minimalist entry detail.
Coatings—powder coat, anodized, wood grain transfer, PVDF—resist corrosion in coastal environments and heavy wear, keeping maintenance low.
As a manufacturer, we provide performance data packages and test reports so specifiers can meet energy codes faster.
Customizable Styles
Glass: double tempered with argon, triple tempered, Low-E, laminated, or tinted—chosen for thermal or acoustic performance needs.
Profiles: thicknesses from 1.8 mm to 5.0 mm and frame widths of 103 mm or 129 mm, selected to match opening size and wind load.
Panel sizes: sliding panels up to 4000 mm wide by 6000 mm high, subject to engineering review.
Finishes: RAL powder coat, anodized silver or black, wood grain transfer, or PVDF coating for long-term exterior color retention.
Opening styles: pivot, swing (inswing, outswing, French), sliding, bifold (inward/outward, straight or corner tracks), and folding.
Hardware Accessories
Locks: multi-point and four-side six-point mechanisms, plus flush locks for sliding panels that keep edges clean.
Hinges: concealed or pivot axis systems available on select pivot and swing doors, supporting heavy panels with minimal sightlines.
Weather sealing: EPDM gaskets and hidden drainage channels, with 45° corner keys that add frame rigidity for long-term performance.
Handles: KERSSENBERG levers or custom styles and finishes; other brands can be specified per project.
Smart options: fingerprint modules and smart locks can be integrated into entry doors upon request, with compatibility confirmed during technical review.
Basic Parameters
Parameter | Typical Performance | Buyer Note |
|---|---|---|
Thermal Insulation | U-Factor 0.38 (W-Z3, 8+21A+8 argon-filled double tempered glass) | Value depends on glazing and frame configuration; request project-specific data. |
Wind Pressure Resistance | 5 kPa (W-Z3, P103) | Rating varies with panel size; confirm wind load report for your opening. |
Water Tightness | 700 Pa (W-Z3), 450 Pa (P103) | Coastal projects may need higher ratings and PVDF coating; ask for test report. |
Air Tightness | 1.2 m³/(m·h) (W-Z3), 4.5 m³/(m·h) (P103) | Pivot doors achieve tighter air leakage; sliding values subject to type and seal quality. |
Sound Insulation | 35 dB (W-Z3), 30 dB (P103) | Laminated or triple glazing can improve sound reduction; request acoustic report. |
