Explore certified architectural aluminum, cast aluminum, fire-rated steel, and double-glazed entrance doors precision-manufactured at our Foshan facility.
In contemporary architectural design, the entrance door is no longer merely a point of ingress; it represents a primary thermal barrier, a statement of aesthetic luxury, and a critical structural element engineered to withstand extreme environmental loads. As commercial developers, custom villa builders, and global procurement teams seek direct access to specialized manufacturing, sourcing directly from a qualified China Glass Entry Door Wholesale Supplier & Factory has transitioned from a cost-reduction strategy to an essential competitive advantage.
Selecting structural glazing systems requires rigorous evaluation of thermal transmittance (U-value), solar heat gain coefficients (SHGC), wind load deflection limits (L/175), and acoustic attenuation ratings (STC/OITC). DERCHI provides full spectral data and certified test reports for every batch.
Navigating complex international building codes—such as North America’s NFRC/ASTM, Australia’s AS2047/AS1288, and Europe’s EN 14351-1—demands factory-level engineering capability, documented Quality Assurance, and mill-certified structural alloys.
Headquartered in Foshan, China—the global capital of aluminum extrusions and architectural hardware—DERCHI leverages a vertically integrated 180,000 m² smart factory layout to provide end-to-end OEM and ODM door solutions.
Our Foshan manufacturing ecosystem operates under Industry 4.0 guidelines, integrating automated precision extrusion, robotics-assisted glass lamination, CNC profile processing, and digitalized quality tracking.
We exclusively utilize primary 6063-T5 aluminum billets with wall thicknesses ranging from 2.0mm to 4.0mm, ensuring tensile strength > 205 MPa for oversized pivot and sliding structures.
Double and triple insulated glass units (IGUs) are assembled in dust-free cleanrooms utilizing automated desiccant filling and secondary structural silicone sealing to prevent dew-point failures.
Hinge mortising, lock-body routing, and drain slotting are completed on 5-axis German-engineered CNC centers, maintaining dimensional tolerances within ±0.2mm across 4-meter profiles.
From AkzoNobel fluorocarbon (PVDF) coatings to hyper-durable anodizing and Italian wood-grain sublimation, coatings are salt-spray tested for up to 3,000 hours without blistering.
Capacity, scale, and compliance parameters supporting international distribution networks.
Architectural glass entry doors must balance visual transparency with stringent energetic and structural demands. DERCHI's engineering department integrates state-of-the-art materials to push performance limits.
By applying microscopic layer stacks including three layers of pure silver, our glass units reflect far-infrared heat radiation while admitting high visible light transmittance (VLT > 65%). This achieves Solar Heat Gain Coefficients (SHGC) as low as 0.22 in sun-bathed tropical or desert climates.
Our next-generation roadmap includes ultra-thin VIG options where a 0.3mm vacuum cavity replaces conventional gas fills. This yields an incredible center-of-glass U-value down to 0.6 W/(m²·K) in a profile thickness of only 10.3mm, ideal for slim-line architectural designs.
For hurricane-prone regions (such as Florida or coastal Australia), we utilize SentryGlas® (SGP) ionoplast interlayers. SGP is 5 times stiffer and 100 times tougher than traditional PVB, ensuring structural integrity even if both glass panes suffer severe impact.

Every project sector imposes unique functional, legal, and operational constraints. DERCHI customizes structural extrusions, glass recipes, and hardware integration to address diverse global applications.
High-end residential builds demand grand scale and minimal sightlines. Our floor pivot glass entrance systems carry weights up to 500 kg effortlessly while featuring concealed hydraulic closers, smart biometric access, and multi-point perimeter latching.
High-traffic commercial entrances require structural durability rated for millions of cycles. DERCHI integrates heavy-duty Dormakaba or Geze hardware, panic hardware compliance, auto-actuated sliding systems, and draft-excluding brush seals.
Salt-laden coastal air degrades standard hardware rapidly. We deploy 316-grade stainless steel fasteners, marine-grade anodized aluminum profiles, and corrosion-resistant EPDM gaskets tested under extreme thermal cycling.
Exporting architectural glass systems requires more than physical manufacturing; it demands complete alignment with destination-country building regulations, site approval processes, and insurance mandates.
DERCHI systems undergo testing referenced against NFRC 100/200 for thermal performance (U-Factor / SHGC) and ASTM E283/E330/E331 for air infiltration, structural wind loading, and water penetration resistance. Florida Product Approvals are available upon request for HVHZ zones.
Our doors are fully certified under AS2047 (Windows and External Glazed Doors in Buildings) for wind pressure ratings up to N6 / Cyclonic C4, as well as AS1288 for safety glazing selection and human impact compliance.
Manufactured under EN 14351-1 harmonized standard, carrying verified CE markings for air permeability (Class 4), water tightness (Class E1050), and resistance to wind load (Class C5).
Navigating overseas procurement demands predictable lead times, transparent engineering submittals, and secure export packaging. DERCHI standardizes every stage of the order lifecycle.
Our engineering office converts architect schedules into detailed CAD shop drawings, elevation views, and BIM Revit families within 48 hours of project sign-off.
Physical aluminum corner samples, glass coating swatches, and hardware sets are air-freighted for designer stamping prior to mass production.
Production runs over 25 to 35 business days. In-line quality checkpoints inspect profile dimensions, coating thickness (microns), and glass seal integrity.
Doors are packed in fully enclosed fumigation-free plywood crates with steel reinforcement, EPE corner guards, and desiccant bags, keeping transit breakage under 0.1%.
Key insights for architects, builders, and procurement officers sourcing glass entry doors directly from China.
Our competitiveness relies on vertical integration in Foshan. By controlling aluminum extrusion, anodizing, glass lamination, CNC machining, and assembly within a single 180,000 m² footprint, DERCHI eliminates sub-contractor markups. Furthermore, we test and certify our door systems against international standards (AS2047, NFRC, CE), providing tier-one quality at direct factory costs.
For standard architectural production, single pivot door leaves can reach up to 2,000 mm in width and 4,000 mm in height. Engineered custom systems utilizing internal steel reinforced frames and heavy-duty German-manufactured floor pivots (rated up to 800 kg) can accommodate even larger custom dimensions while maintaining effortless manual operation and precise perimeter seal compression.
Thermal break aluminum entry doors utilize reinforced polyamide insulation strips (PA66GF25) that physically separate the interior and exterior aluminum profiles. Combined with double or triple Low-E argon-filled glazing units, overall system U-values drop to between 1.6 and 1.9 W/(m²·K). This severely restricts heat conduction, preventing interior condensation in freezing northern winters and reducing air-conditioning loads in desert heat.
Standard lead times are 12 to 18 days for technical drawing approval and custom sample creation, followed by 25 to 35 days for containerized batch production. Because DERCHI specializes in custom project manufacturing, we do not impose restrictive minimum order quantities—single custom sample doors for mockup evaluation or multi-unit commercial project lots are both fully supported.
Our packaging protocol utilizes a 5-layer protective sequence: 1) Protective scratch-resistant film on profiles; 2) EPE foam corner guards; 3) Double-wall corrugated wrap; 4) Vacuum sealed desiccant packaging; and 5) Heavy-duty, non-fumigation ISPM-15 compliant plywood crates with internal structural timber supports. This reduces ocean transport damage claims to less than 0.1%.
