1. The wall thickness of aluminum profiles for doors and windows is required to comply with the current national standard high-precision level, and the minimum wall thickness of load-bearing components should be ≥ 1.4mm.
2. The load-bearing members of doors and windows (such as the light hooks, center columns, sliding beams with brightness, sliding beams with brightness, double-sided edges, etc.) must undergo strict compressive calculations. When profiles are used as load-bearing members, their wall thickness should be selected through calculation based on the usage conditions. The load-bearing components of aluminum alloy doors and windows should be determined through testing or calculation.
