How to judge the quality of aluminum alloy door and window profiles?
Three key checks: 1. Surface: High-quality profiles have a smooth, even finish. 2. Thickness: Main profile wall thickness should not be less than 1.8mm. 3. Material: Opt for primary aluminum alloy (grade 6063-T5).
Why do some aluminum doors/windows operate roughly or make noise?
Main causes include dirt in tracks, poor quality hardware (rollers, hinges), improper installation causing frame distortion, or insufficient profile rigidity.
What are "Thermal Break" aluminum alloys and their advantages?
A thermal break profile uses a low-conductivity material (PA66 nylon) to break the thermal bridge. It offers superior thermal insulation, energy efficiency, and improved sound insulation.
How to check the sealing performance of aluminum doors and windows?
Focus on EPDM gaskets for elasticity. Check if they are continuous and compress tightly. A simple test is trying to pull a sheet of paper from a closed sash—it should be difficult to remove.
What are the considerations for high-rise building installations?
Safety is paramount. Use high-strength profiles and tempered safety glass (laminated is recommended). Hardware must have high load-bearing and wind resistance, secured with galvanized steel brackets.
Can the color and size be customized for specific projects?
Yes, both size and color are fully customizable to meet the specific requirements of residential or commercial construction projects.
