Directly extruded, glazed, and tested from our 180,000 m² Foshan manufacturing base. Each system complies with global building envelopes including AS 2047, CE, ISO 9001, and UL fire ratings to resist seismic displacement, dynamic transit vibration, and extreme coastal weather.
Unlike standard on-foundation residential fenestration, mobile home, modular dwelling, and shipping container conversions present unique physical demands. Structural deflection during transport, wind torsional loads along open highways, and severe thermal bridging in compact envelopes demand higher tensile strength profiles, flexible sealing matrices, and lightweight thermal-break performance.
DERCHI fabricates profiles utilizing primary architectural aluminum billet 6063-T5 and T6 temper. Our mobile home window extrusions feature minimum web thicknesses from 1.4mm to 2.0mm, delivering up to 205 MPa tensile yield strength. This structural safety margin eliminates frame warping caused by repeated road shocks and chassis flexion during modular transport.
Condensation is the primary failure mode of low-cost mobile home fenestration. By integrating reinforced PA66 GF25 (25% glass fiber-reinforced polyamide) thermal struts, our thermally broken extrusions interrupt interior-to-exterior heat transfer pathways. This achieves total window U-factors as low as 0.28 BTU/(hr·ft²·°F) [1.6 W/(m²·K)], meeting US Title 24, IECC, and Australian NCC climate zone mandates.
Where commodity manufacturers rely on PVC seals that become brittle under UV radiation and temperature fluctuations, our factory integrates automotive-grade EPDM (Ethylene Propylene Diene Monomer) multi-fin weatherstrips with vulcanized corner vulcanization. This creates continuous compression joints yielding air infiltration rates below 0.1 cfm/ft² at 75 Pa.

Procurement directors and B2B developers across North America, Australia, Europe, and the Middle East are shifting specifications away from low-cost disposable vinyl/aluminum toward sustainable, high-yield architectural envelopes.
Developers are no longer sourcing knock-down (KD) frames for field glazing due to skyrocketing domestic assembly labor costs in destination ports. Procurement contracts require 100% pre-hung, factory-calibrated, and pre-glazed sub-assemblies fitted with custom installation flanges (nailing fins) engineered for direct drop-in integration onto modular steel or light-gauge timber stud frames.
European and US institutional buyers are mandating Environmental Product Declarations (EPD). Modern Chinese tier-1 factories are shifting smelter feedstock to hydropower-derived green aluminum, accompanied by certified raw material traceability to maintain carbon-border adjustment compliance without penalizing unit landing costs.
Due to the global increase in extreme climate events, mobile home windows are increasingly required to achieve dual-action performance: high thermal insulation coupled with ASTM E1886/E1996 Large Missile Impact resistance (or AS 1170.2 cyclonic debris compliance). This bridges the gap between affordable housing and life-safety insurance underwriting.
Operating under Guangdong Dejiyoupin Doors and Windows Co., Ltd., DERCHI stands as one of China's Top 10 premium architectural fenestration brands, combining 25+ years of engineering mastery with industrial-scale manufacturing output.
Our centralized production complex in Shishan Town, Foshan, houses German automated CNC four-corner crimping stations, Italian profile extrusion machining centers, and automated insulated glass production lines. Housing 600+ skilled staff under one roof guarantees precise tolerances of ±0.5mm across bulk orders of 10,000+ units.
We do not rely on self-declarations. DERCHI systems hold accredited physical laboratory test reports for Australian AS 2047 (N6 wind load), American AAMA/WDMA/CSA 101/I.S.2/A440, CE EN 14351-1, ISO 9001 quality management, and UL fire ratings. All engineering shop drawings are supported by certified structural calculations.
International shipping can ruin precision fenestration without rigorous protection. Every DERCHI shipment receives low-tack protective wrap, high-density polyethylene foam corner caps, desiccant bags within moisture-sealed poly bags, and fumigated steel-strapped OSB plywood crates engineered for seamless forklift offloading at modular factory sites.
Direct technical guidance addressing international logistics, custom framing, standards compliance, and container housing integration.
Frame racking occurs when weak friction corners fail under lateral torsional loads. DERCHI uses solid 4.0mm cast aluminum corner cleats injected with anaerobic two-part structural polyurethane adhesive during mechanized hydraulic corner crimping. This creates a monolithic, chemically bonded miter joint that withstands high-speed highway chassis vibrations without distorting frame squareness or pinching sash operation.
Yes. Standard flat-wall residential windows cause significant water leaks when mounted to corrugated container corten panels. We engineer custom extruded aluminum perimeter conversion sub-buck frames that fit directly into the corrugated profile offsets, or provide integral wide nailing flanges (1.5" to 2.5") that allow rapid self-tapping screw fastening and seamless butyl tape flashing.
For hot, high-sun climates (e.g., Texas, Middle East, Australia), we recommend 5mm solar-reflective Low-E + 12A (Argon gas) + 5mm clear tempered glass with a warm-edge TPA/Swisspacer spacer, delivering an SHGC below 0.23. For severe northern winter zones, we supply double Low-E coatings or triple-pane units (4Low-E + 9A + 4Float + 9A + 4Low-E) achieving center-of-glass U-values down to 0.18 BTU/(hr·ft²·°F) [1.0 W/(m²·K)].
For standard project extrusions with standard RAL architectural powder coating finishes, our production cycle is 25 to 35 business days from CAD drawing sign-off. MOQ is flexible: we support project-specific custom runs starting at 20 units for specialized developers, up to multiple 40-foot HQ shipping containers per month for established modular builders. Pre-production mockups can be fabricated and dispatched via express air freight within 10 days.
Coastal marine exposure requires stringent surface treatments. We use 100% Class 2 AkzoNobel or PPG fluorocarbon PVDF finishes with a minimum three-coat 70% Kynar 500 resin system, passing the 4,000-hour continuous salt spray test (ASTM B117). All operational fasteners, friction hinges, rollers, and multi-point mortise lock assemblies are specified in non-magnetic 304 or marine-grade 316 stainless steel.
Yes. International building codes (including IRC and HUD codes) mandate minimum clear opening dimensions for sleeping rooms in mobile dwellings: minimum net clear opening of 5.7 sq. ft., minimum clear opening height of 24 inches, and minimum width of 20 inches. We supply custom side-hung casements and custom-balance single-hung units with quick-release egress latches specifically designed to meet or exceed these life-safety standards.
