01What we supply
Windows & doors
Frames, sashes, mullions and beads for casement, sliding and tilt-turn systems.
Curtain wall
Mullions, transoms, pressure plates and caps for stick and unitized facades.
Railings & balustrades
Posts, top rails and glass channels for balconies and stairs.
Louvres & sun shading
Blades, frames and brackets for ventilation and solar control.
02Finishes for decades outdoors
Anodizing gives a durable metallic finish; exterior work typically specifies 15–25 µm. Powder coating offers any RAL color, with higher-durability polyester grades for strong sunlight. Electrophoretic coating over anodizing adds a clear, smooth protective film. Wood-grain transfer gives timber looks with aluminum's durability.
For facades, color consistency across deliveries matters as much as durability — we approve master color samples with you and check every batch against them.

03Tolerances and standards
Architectural profiles are commonly produced to EN 755-9 or, for 6060/6063 precision profiles, EN 12020-2. Chinese building projects reference GB/T 5237. Local codes also set minimum wall thickness for load-bearing window and door members — tell us your market's code and we design to it.
04Project workflow
Drawings & schedule
System drawings, profile list, finish schedule and delivery phasing.
Samples
Profile samples and finish panels for approval — the master reference for production.
Production
Extrusion, finishing and inspection against the approved samples.
Labelled delivery

06Frequently asked questions
Should window profiles be 6060 or 6063?
Both are standard. 6060 extrudes slightly more easily and gives an excellent surface; 6063 is a little stronger. Many European systems use 6060, while 6063 is the global default. Either anodizes and powder coats very well.
Anodizing or powder coating for a facade?
Anodizing suits metallic architectural finishes and resists abrasion; powder coating offers unlimited colors. Both last decades when specified to the right class. See our finish comparison.
Can you extrude profiles for our own window system?
Yes. We work from your system drawings, make the dies, and submit samples for approval — the dies are reserved for your system only.
