Window & Door Profiles
门窗型材
Product Introduction
Aluminum window and door profiles are the backbone of modern building envelopes. Made from 6063-T5 aluminum alloy, these extrusions combine high strength, lightweight, and corrosion resistance. Our thermal-break profiles integrate PA66GF25 polyamide strips between inner and outer chambers, dramatically improving thermal insulation.
We supply series from 55mm to 120mm for casement, sliding, tilt-and-turn and folding systems. Surface finishes include anodized, powder coating in any RAL color, and wood grain transfer. Backed by 20 years of construction experience, we know how these profiles perform on real sites.
