Curtain wall aluminum profile purchase mainly see where?

Update time : 2023-07-06 11:17:11

1. Appearance quality of curtain wall aluminum profile: the surface of anodic oxide film is not allowed to have electrical burns, oxide film falling off and other defects; Electrophoretic, powder, fluorocarbon profile paint film should be uniform, neat, smooth, do not allow wrinkles, cracks, bubbles, flow signs, inclusions and paint film fall off and other defects, but allow local film within 80 mm at the end of the profile.

The appearance quality of aluminum alloy building profiles affects the effect of architectural decoration, so the surface of the factory curtain wall aluminum profile must be coated with a film to avoid scratches, scrapes and corrosion during transportation and stacking. Some aluminum alloy building profiles on the market also have similar water marks and mold spots in the inner cavity, which reflects defects in the production process.

2. Wall thickness: curtain wall aluminum profile wall thickness is one of the main factors affecting the strength of the workpiece, and the main profile is the stress part of the project. For example, the nominal wall thickness of the main profile of the exterior window must not be less than 1.4mm.

3. Chemical composition, mechanical properties: different grades of aluminum profiles, the supply of chemical composition, technical parameters of mechanical properties are different, customers should be checked according to the standard (contract) one by one.

4. Color and color difference: in the supply state, there are color and color differences between different grades and alloys, it is recommended that when selecting alloy grade and supply state, the impact of color and color difference on the building structure should be fully considered.

5. Salt spray corrosion resistance, wear resistance, weather, mortar, etc. : This is an important technical parameter of the curtain wall aluminum profile, which reflects the performance of the curtain wall aluminum profile and affects the use.
