China Wholesale Aluminium Internal Glass Doors Supplier & Suppliers

We exclusively utilize high-grade virgin 6063-T6 or 6061-T6 aluminum alloys that comply with ASTM B221 and GB/T 5237 standards. Our architectural surface finishes include Qualicoat Class 2 certified powder coatings, fluorocarbon (PVDF) finishes exceeding AAMA 2605 requirements, and Class I architectural anodizing (minimum 18-micron layer). These surface treatments protect against oxidation, UV degradation, cleaning abrasions, and humidity-induced corrosion in luxury interior environments.

Yes. Standard single-glazed sliding panels typically deliver between STC 28 and 31. To achieve ratings between STC 38 and 42, DERCHI engineers combine our deep perimeter profiles with double-sealed acoustic laminated glass (such as 5mm + 0.76mm acoustic PVB + 5mm) or argon-filled acoustic double-glazed units (IGUs). Systems are fitted with dual-perimeter German-formulated EPDM co-extruded gaskets and high-tolerance automatic drop-down mechanical thresholds that seal air gaps when the panel engages the jamb.

Oversized panels measuring over 3,000mm in height or 1,500mm in width require robust structural anchoring. DERCHI integrates internal tensioning stabilizer rods within the profile stiles. These rods can be finely adjusted on site to counteract natural deflection and ambient changes. Additionally, our pivots utilize oil-bath hydraulic bottom pivots capable of carrying loads up to 500kg, certified for over 200,000 continuous opening and closing cycles without vertical displacement.

All internal glazing is produced in strict compliance with ANSI Z97.1 (USA), CE EN 12150 / EN 12600 (European Union), and AS/NZS 2208 (Australia). We supply fully tempered safety glass, multi-layered laminated safety glass (utilizing genuine Saflex PVB or SentryGlas interlayers), and custom patterned glass variants (reeded, fluted, frosted, or low-iron ultra-clear). Glass panels undergo rigorous thermal stress testing and surface compression analysis before framing.

Standard OEM production ranges between 25 and 35 calendar days following client sign-off on detailed CAD shop drawings. For export logistics, every individual door frame and glass leaf is encapsulated in protective PE surface tape, cushioned with custom high-density EVA corner guards, and enclosed in fully enclosed, fumigated marine-grade plywood crates. Crates feature bottom pallet skids for safe forklift operation and silica gel desiccant packs to prevent condensation damage during transoceanic shipping.
