Top China Aluminum Half Glass Door Supplier & Exporter

While both originate from the Al-Mg-Si series, 6063-T5 is artificially aged following profile extrusion air-cooling, achieving a typical tensile yield strength of 145–160 MPa. In contrast, 6063-T6 undergoes intensive solution heat treatment followed by artificial precipitation hardening, boosting yield strength to 215+ MPa and Webster hardness to ≥12 HW. For large-format aluminum half-glass doors—where the heavy bottom panel and cantilevered double-glazed top load induce torsional stress—DERCHI specifies 6063-T6 across all primary structural jambs, mullions, and transom corners to eliminate structural deflection over decades of high-cycle operation.

Our thermal break profiles incorporate original German Technoform PA66 GF25 (polyamide with 25% chopped glass fiber reinforcement). This composite matches the linear thermal expansion coefficient of aluminum (2.4 × 10⁻⁵ / K), eliminating thermal shear stresses that cause cheaper PVC or recycled nylon thermal strips to debond or delaminate under acute temperature deltas. Combined with automated knurling and high-pressure crimping machines with integrated electronic pull-off shear testing, every linear meter delivers shear strength exceeding 24 N/mm in compliance with EN 14024.

Yes. The solid lower section can be engineered to your precise architectural elevation and interior design requirements. Material choices include monolithic architectural aluminum plates (2.5mm–4.0mm), 3D CNC fluted aluminum slats, cast aluminum artistic reliefs, or acoustic composite sandwich panels. The interior core can be filled with high-density polyurethane (PU) foam (42 kg/m³) for superior thermal insulation, high-density rockwool (100 kg/m³) for fire retarding performance, or an aluminum honeycomb core to achieve maximum dent resistance and anti-kick durability.

DERCHI doors are tested in accordance with Australian Standard AS 2047 / AS 1288 (achieving the highest N6 structural wind class), North American NFRC (U-factor and SHGC certification), ASTM E283 (air leakage), ASTM E331 (water penetration resistance up to 700 Pa), ASTM E330 (structural load testing), and European CE EN 14351-1. For specialized commercial projects, we also provide UL 10C positive pressure fire-rated assemblies rated from 20 to 90 minutes.

To eliminate hardware failure—the primary failure mode of exterior doors—we partner directly with Tier-1 European hardware innovators including German Roto, Siegenia, HOPPE, G-U, and DORMA, alongside our proprietary DERCHI heavy-duty stainless steel 304/316 concealed pivots and continuous geared hinges. Exterior doors feature 3-point or 5-point mushroom-cam locking systems with anti-drill, anti-snap euro profile cylinders meeting RC2/RC3 anti-burglary standards.

Following final CAD shop drawing sign-off and deposit receipt, standard bespoke production takes 25 to 35 calendar days. For complex configurations requiring custom anodized color matching, triple-glazed laminated glass, or curved profiles, lead time is 35 to 45 days. Ocean shipping from Shenzhen or Guangzhou ports is approximately 14–18 days to the US West Coast, 28–32 days to the US East Coast, 18–24 days to Australia, 25–30 days to Europe, and 18–22 days to Middle Eastern ports (Jebel Ali, Dammam, Doha).

We deploy a five-tier export crating standard: First, all aluminum surfaces are covered with an anti-scratch static protective film; second, high-impact foam corner protectors are installed over all four corners; third, the entire leaf is sealed in multi-layer pearl cotton foam; fourth, doors are placed on custom structural steel A-frames or packed in ISPM-15 compliant, fully enclosed plywood cases reinforced with steel strapping; finally, moisture-absorbing silica desiccant bags are sealed inside to prevent condensation during tropical ocean voyages.

Standard export payment terms are 30% to 50% T/T deposit upon engineering CAD sign-off, with the balance payable upon production completion and provision of comprehensive pre-shipment inspection photos and videos prior to container dispatch. Irrevocable Letters of Credit (L/C at sight) are accepted for institutional projects. With every shipment, we furnish clean Bills of Lading (B/L), Commercial Invoices, Packing Lists with crate numbers and contents, Certificates of Origin (CO / Form A / Form E), and factory Mill Test Certificates.
