China Top Aluminium Framed Glass Doors Suppliers & Exporters

At DERCHI, every batch of primary aluminium billets is certified for chemical composition via spectral analysis, conforming strictly to 6063-T5 or 6063-T6 specifications. In accordance with international standards, our structural frame extrusions maintain a wall thickness between 2.0mm and 3.0mm for heavy-duty sliding and grand pivot doors, and never less than 1.4mm for secondary interior casements. Optical micrometers and ultrasonic thickness gauges verify structural profile walls before powder coating or anodization.

Our hurricane-rated collections feature laminated safety glass configurations (e.g., 6mm + 1.52mm PVB/SGP + 6mm) mounted in reinforced aluminium multi-track frames with heavy-duty interlocking mullions. Having successfully passed Australia's AS 2047 N6 rating and cyclonic testing standards, our systems withstand ultimate positive and negative design wind pressures exceeding 4500 Pa, combined with continuous water resistance thresholds above 600 Pa.

Upon receipt of your architectural window and door schedules, our technical engineering office produces detailed CAD shop drawings within 48 to 72 business hours. Once shop drawings, hardware specs, and finish samples are approved, standard production lead time runs between 25 and 35 calendar days depending on whether custom extrusion dies or non-standard RAL fluorocarbon colors are required.

DERCHI provides an extensive portfolio of compliance testing documentation. Our systems are verified under CE standards (EN 14351-1), ISO 9001 Quality Management Systems, Australian AS 2047 / AS 1288 fenestration codes, and North American testing protocols including UL fire ratings. All test reports are accompanied by third-party laboratory accreditations to facilitate smooth approval with municipal building inspectors and structural engineers.

We partner with leading global hardware manufacturers including Siegenia, Hoppe, Roto, CMECH, and custom DERCHI architectural hardware. Our sliding systems utilize CNC-machined stainless steel tandem rollers rated for 300kg to 500kg per sash with silent polymer bearings. Swing and casement doors feature 304/316 stainless steel multi-point locking gearings, and grand pivot doors utilize commercial German hydraulic floor springs with 90° hold-open and auto-soft-close dampening.

Export shipments are protected against long-haul marine moisture and physical abrasion. Profiles receive protective electrostatic peeling film, glass panels are separated by cork vibration pads, and entire units are vacuum-sealed with anti-humidity silica gel desiccants. Finished frames and panels are loaded onto custom heavy-duty steel or ISPM-15 heat-treated plywood crates designed for safe forklift and overhead crane container unloading.
