China Best Aluminium Frameless Doors Manufacturers & Manufacturer

Frameless fenestration does not rely on unsupported glass edges. Structural rigidity is attained through three integrated engineering choices: first, the use of primary 6063-T6 or 6063-T66 aerospace-grade aluminium alloy tracks concealed in ceiling and slab assemblies; second, structural glass composition using heat-strengthened laminated glass with high-shear ionoplast interlayers (such as SentryGlas / SGP); and third, high-modulus structural silicone bonding (SSG) that transfers negative and positive gust forces directly into building structural slabs rather than decorative frames.

While standard residential sliding doors frequently use 6063-T5 aluminium (with an ultimate tensile strength of around 150-160 MPa), architectural frameless and minimalist interlocks require 6063-T6 or artificially aged T66 temper. T6 temper delivers an ultimate tensile strength of ≥205 MPa and yield strength of ≥170 MPa. This heightened mechanical capacity allows vertical interlocking stiles to be slimmed down to 16 mm - 20 mm while maintaining deflection ratings within the permissible span limit of L/175 or L/250 under high-velocity wind loads.

Flush-floor transitions eliminate tripping hazards but present severe water ingress challenges if not engineered correctly. DERCHI utilizes an integrated cascading concealed drain trough positioned below finished floor level. The bottom extruded aluminium track features linear weep slots coupled with internal EPDM drainage baffles and a sloped sub-sill catchment channel. Water is collected and evacuated through 50mm drain spigots routed into the perimeter building stormwater system, preventing back-siphonage even under driving rain pressures up to 600 Pa.

Yes. Our 180,000㎡ Foshan production facility is outfitted with heavy-tonnage vertical processing stations capable of fabricating single-panel heights up to 5,000 mm and widths up to 3,000 mm. For spans beyond 3,500 mm, internal stainless steel or carbon-fiber reinforcement bars are fitted inside the vertical aluminium interlocks to prevent wind-induced lateral bowing, and multi-wheel tandem carriages with Japanese stainless steel needle bearings are utilized.

For projects situated within 5 km of an ocean coastline (such as coastal Florida, Sydney, the Caribbean, or coastal South America), we apply AAMA 2605-compliant 3-coat fluorocarbon PVDF liquid finishes (70% Kynar 500 resin base) or marine-grade hard-anodized coatings (Class 1, minimum 25-micron oxide layer thickness). These chemical finishes undergo 3,000+ hours of neutral salt spray testing (ASTM B117) to ensure zero chalking, fading, or filiform pitting over extended exposure.

Before production, our in-house engineering team converts client architectural designs into parametric 2D/3D CAD shop drawings, detailing rough opening tolerances, structural anchor centers, and perimeter water-proofing membranes for formal sign-off. Following dispatch, each crated component is numbered according to the project door schedule. We provide detailed installation manuals, exploded 3D component renders, and real-time video technical support scheduled according to the buyer's local time zone.

Our standard Minimum Order Quantity (MOQ) is 1 set for customized villa projects or prototype evaluation, though tiered commercial pricing applies for full container loads (20GP / 40HQ). Standard production lead times run between 25 to 35 calendar days following shop drawing approval. We routinely quote EXW, FOB (Shenzhen / Guangzhou / Foshan), or CIF to any major commercial ocean terminal globally.
