Cracks, burrs, peeling or corrosion are not allowed on the surface of the aluminium profile. No obvious scratches, craters or bruises are allowed. In the transportation of aluminium profiles, ensure that the protective film is intact, and the handling process should pay attention to the phenomenon of bruising.

Thickness
The actual extrusion process involves the following details;


The price of the aluminium windows is directly related to the price of aluminium ingots. Generally, the price of the aluminium windows is relatively stable. The price of the high-quality aluminium windows is usually 30% higher than poor quality aluminium windows. Poor quality aluminium windows usually contains a large amount of inferior and non-compatible materials and their thicknesses are only 0.6-0.8 mm. Hence, when choosing aluminium windows, we should take note of the price and look into their profile and specification to ensure that their thickness and strength meet the relevant national standards.
Despite these advantages, metal taps can be more expensive and may require more effort during installation due to their weight and complexity. Moreover, certain metals are susceptible to corrosion, especially in harsh environments, necessitating the use of protective coatings or alloys.
