Explore our factory-direct product catalog engineered in our 180,000㎡ industrial park. Every unit is manufactured with tight profile tolerances, marine-grade powder coating, and precision-balanced hardware designed for smooth operation and durability.
While double and triple glazing dominate temperate and sub-arctic climate zones, monolithic single pane aluminum sliding windows maintain an indispensable, high-volume market presence globally. In regions such as Southeast Asia, the Pacific Basin, Latin America, the Caribbean, parts of Africa, and the Middle East, single pane fenestration offers unmatched economic efficiency, simplified structural deadweight, and ease of maintenance.
Our profiles are extruded using primary 99.7% virgin aluminum billets. We enforce precise wall thicknesses (1.2mm, 1.4mm, up to 2.0mm) strictly aligned with ASTM B221 and GB/T 5237 standards. Internal reinforcement chambers allow sashes to withstand high wind loads (up to 3000 Pa design wind pressure) without deflection.
Single pane does not mean basic float glass. We fabricate with 4mm, 5mm, 6mm, and 8mm Grade A toughened tempered safety glass (ANSI Z97.1 / EN 12150). For specialized acoustic and security needs, we provide monolithic laminated glass (e.g., 3mm + 0.38PVB + 3mm) or tinted solar control glass to cut solar heat gain coefficient (SHGC).
Gliding friction is minimized through dual stainless steel SUS304 roller bearings encased in noise-damping POM / nylon shells. Paired with extruded stainless steel track runners embedded in the sill, the window sash achieves 100,000+ open-close duty cycles without track abrasion or jumping.

Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) represents China’s tier-one manufacturing capability. Recognized among the Top 10 fenestration and door brands in China, our integrated industrial footprint in Nanhai District delivers unmatched scale, engineering rigor, and global logistics reliability.
We provide comprehensive shop drawings, structural wind load analysis, and extrusion die opening within 12 days. Whether you supply an architectural bill of quantities (BOQ) or require bespoke profile geometries for modular housing, our CAD/BIM engineering team delivers precise submittal files.
Our window systems have successfully satisfied Australia AS 2047 N6 wind resistance tests, CE certification standards for the European Union, ISO 9001 quality audits, and UL fire ratings. When developers submit DERCHI technical schedules to municipal authorities or third-party engineering consultants, approvals are fast-tracked.
Windows are packed either fully assembled (SKD) with protective blue PE film and heavy-duty fumigated wooden crates, or in flat-pack knock-down (CKD) modular kits to optimize ocean freight container payloads by over 140%. Container stuffing plans are digitized to eliminate cargo shift and glass stress fractures.
The international building envelope sector is shifting rapidly. Procurement directors, facade engineers, and general contractors are adapting to four pivotal trends impacting single pane sliding window specifications through 2030.
Global developers increasingly mandate Environmental Product Declarations (EPD). Modern aluminum sliding windows now adopt recycled-content hydro-powered aluminum billets (such as 6063 scrap loops), slashing embodied carbon from 16 kg CO2e/kg to under 4.0 kg CO2e/kg while maintaining identical tensile strength.
High container shipping rates have turned B2B buyers toward Completely Knocked Down (CKD) window systems. Using smart corner-key crimping and dry-glazing gaskets, contractors can assemble and glaze single pane sliding sashes on-site in under 8 minutes without messy wet silicones.
In hot coastal and tropical resort developments, standard 5-year powder coatings fail from UV chalking and salt-spray blistering. Sourcing schedules now specify Qualicoat Class 2 or AAMA 2604 compliant super-durable polyurethane systems with 15 to 20-year colorfast warranties.
In Southeast Asia, Australia, and the Americas, single pane sliding systems are demanded as a dual-track or triple-track integrated unit with woven 0.8mm high-tensile 304 stainless steel security screens, eliminating external burglar bars while allowing cross-ventilation.
Clear, technically rigorous answers to critical engineering, manufacturing, and international trade questions encountered during window schedule tenders.
Wind load capacity is determined primarily by the moment of inertia (Ix value) of the central interlock aluminum mullion, not merely the glass thickness. By engineering internal steel or thicker structural aluminum reinforcing fins, our single pane sliding systems achieve wind ratings exceeding 2,500 Pa (equivalent to Category 3-4 hurricanes) while utilizing 6mm or 8mm tempered monolithic glass.
For our standard architectural sliding profile dies, our minimum order quantity is 50 square meters or approximately one 20ft container (LCL trial shipments are accommodated for approved developer contracts). For custom OEM extrusion cross-sections, new die tooling requires 7-10 days, followed by sample delivery in 5 days. Full 40HQ container manufacturing lead times average 20-25 days.
We employ a pressure-equalized cascading step-sill design. Drainage weep holes are machined with internal directional PVC / POM gravity flappers that open under water head pressure to vent water outward, but automatically snap shut against external gusting wind pressure, preventing reverse rainwater siphonage during monsoons.
Yes. We accommodate full OEM hardware customization. Options range from standard zinc-alloy cam crescent latches and spring-loaded pop-up sash locks to automated magnetic reed sensors and flush pull handles. We partner with world-class hardware vendors (such as Hoppe, Siegenia, Kin Long, and Kingdee) or install your client-designated brands.
Every window sash is shrink-wrapped with protective scratch-resistant film and cushioned with dense EVA corner guards. Completed units are loaded into steel-reinforced, fully enclosed non-coniferous fumigation-free plywood crates equipped with desiccant packs to prevent moisture condensation during sea voyage crossings.
Every export batch is accompanied by Certified Mill Test Reports (MTR) for aluminum alloys, glass temper heat-treatment certificates (ANSI Z97.1 / EN 12150), Certificate of Origin (Form E, Form A, or RCEP for preferential tariff status), packing lists, commercial invoices, and factory inspection reports detailing dimensional tolerances and roller duty cycles.
