Frequently Asked Questions
How to judge the quality of aluminum alloy door and window profiles?
Check three key aspects: Surface finish (should be smooth and even), Thickness (should not be less than 1.8mm for main profiles), and Material (opt for primary 6063-T5 alloy).
Why do some aluminum doors operate roughly or make noise?
Common causes include debris in tracks, poor quality hardware like rollers, improper installation causing frame distortion, or insufficient profile rigidity.
What are "Thermal Break" aluminum alloys and their advantages?
They feature a low-conductivity strip (PA66 nylon) between aluminum parts to break the thermal bridge, offering superior insulation, energy efficiency, and better soundproofing.
How to check the sealing performance?
Focus on EPDM gaskets for elasticity. They should be continuous and compress tightly. A good test is trying to pull a sheet of paper through a closed sash; it should be difficult to remove.
What are the considerations for high-rise building installations?
Safety is critical. Use high-strength profiles and tempered safety glass (laminated is recommended). Installation must be reinforced with galvanized steel brackets.
What surface treatments are available?
We offer Anodizing, Powder coating, Electrophoresis, and Fluorocarbon (PVDF) paint in various customized colors.
