Custom OEM Aluminum Glass Front Doors Manufacturers & Exporters

Because every commercial or residential development features distinct structural openings and architectural finishes, our production is completely tailored. Our standard MOQ is 1 set for bespoke custom villa projects or 10 to 50 sets for commercial real estate developments. Following the mutual sign-off of our detailed CAD shop drawings, fabrication requires approximately 25 to 35 working days for standard RAL powder-coated finishes, or 35 to 45 working days for customized extruded profile molds, specialized thermal break bridging, or wood-grain fluorocarbon sublimation finishes.

Exterior doors exposed to direct solar radiation while insulating air-conditioned or heated interiors experience significant temperature differentials between inner and outer profile walls. This phenomenon, known as the "bimetallic strip effect," can lead to frame warping, latch binding, and air seal degradation. To eliminate this risk, our engineering division implements split-profile composite thermal break strips (anti-bi-metal polyamide barriers). These specialized shear-stress-reducing profiles permit differential mechanical movement without structural curvature, preserving airtightness across temperatures ranging from -35°C to +80°C.

For all deliveries destined for the European Union, United Kingdom, and affiliated trade zones, DERCHI supplies a full Declaration of Performance (DoP) package compliant with Construction Products Regulation (CPR). This documentation includes accredited notified-body laboratory test reports verifying initial type testing (ITT) for air permeability (EN 12207), water tightness (EN 12208), wind load resistance (EN 12210), acoustic attenuation (EN ISO 717-1), and thermal transmittance (EN ISO 10077-2 calculations). Factory Production Control (FPC) records certified under ISO 9001:2015 accompany every export bill of lading.

Our ocean freight packaging protocols are specifically engineered for heavy, fragile architectural elements. Finished door leaves and framing assemblies undergo five defensive layers: (1) peelable protective polymer film across all powder-coated surfaces; (2) dual-layer high-density pearl cotton edge guards; (3) moisture-impermeable shrink wrapping with desiccant packs; (4) corner impact shock absorbers; and (5) fully enclosed, ISPM-15 heat-treated fumigated plywood crates reinforced with internal steel perimeter strapping. Heavy pivot leaves are crated horizontally or in custom heavy-duty steel A-frames designed for direct overhead crane or forklift unloading.

Yes. A primary operational advantage of partnering with DERCHI's 180,000 m² production base is our unified "Whole-House Architectural Fenestration Package." General contractors and property developers can consolidate high-security aluminum glass front entry portals, minimalist interior flush wooden doors, thermally broken patio bi-folds, panoramic lift-and-slide doors, and matching exterior structural curtain wall modules inside consolidated 40ft HQ shipping containers. This eliminates freight volume wastage, consolidates customs clearance documentation, and guarantees exact surface color, glass tint, and hardware finish harmony across the entire project.
