Extrusion defect
In the production process of alu extrusion profiles, due to the failure of extrusion equipment and improper operation process, some extrusion defects will occur. These defects include bubbles, inclusions, delamination, color, deformation, etc. Therefore, every customer should carefully check their purchase for many problems.
Thin oxide film thickness
The general standard for the thickness of architectural alumina film should not be less than 10 microns. If the thickness of this part is not enough, the surface of the alu extrusion profile will be prone to rust and corrosion. Manufacturers of these low quality products even sell related products with an oxide film thickness of 2 to 4um, and some of their products don't even have an oxide film. Therefore, every customer should choose an honest manufacturer first.
chemical composition failure
Low-quality aluminum suspended baffle ceilings, often containing large amounts of miscellaneous aluminum. Although this production method can greatly reduce the cost, it will cause the chemical composition of the aluminum structure to fail, which will cause serious problems in the construction project.
The anti-corrosion process is significantly reduced
Manufacturer of low-quality alu extrusion profiles, doing everything possible to reduce production costs. For example, they will reduce the consumption of chemical reagents and shorten the cycle time of the anticorrosion process. While this method helps reduce costs, it largely reduces the corrosion resistance of aluminum extrusions.
