Aluminum profiles are widely used in the construction industry because of their environmental protection, stability, easy processability and decoration. Aluminum alloy profiles can be divided into base materials, anodized profiles, electrophoretic coating profiles, powder spraying profiles, fluorocarbon paint spraying profiles, striped thermal insulation profiles, glue injection thermal insulation profiles and so on. Next, I would like to introduce to you how many ways to break the bridge of alu......
1. From the point of view of materials, the thickness, strength and oxide film of high-quality aluminum door and window machinery should meet relevant standards. The wall thickness should be greater than 1.2 mm, the tensile strength should reach 157 Newtons per square millimeter, the yield strength should reach 108 Newtons per square millimeter, and the oxide film thickness should reach 10 microns. If it does not meet the above standards, it is a low-quality aluminum alloy door and window equip......
