The polished aluminum angle trim is made of aluminum alloy material, which is simpler in craftsmanship, but has strict requirements on the machine to be produced. It is mainly used in aluminum grilles and aluminum ceiling ceilings. It has the function of hiding pipeline facilities. During use, it has the function of enhancing the exhaust of the house.
The aluminum alloy keel looks quite similar to the aluminum corners in appearance, but their manufacturing process is not the same. The treated aluminum alloy keel is not easy to rust, and is not easy to change color, and it is also effective for outdoor corridors.
To learn how to identify low-quality polished aluminum angle trim, generally poor-quality aluminum corners have the following characteristics:
①: Visual inspection: the appearance and color are dim, no brightness, no metallic luster, almost no appearance requirements.
②: The chemical composition is unqualified. The aluminum corners mixed with a large amount of miscellaneous aluminum and scrap aluminum can greatly reduce costs and seriously endanger the stability of construction projects.
③ Inferior aluminum corners greatly reduce the sealing time, reduce the loss of chemical reagents, and reduce the cost, but the corrosion resistance of the profile is also greatly reduced. Air, rain, sunlight, etc. will also affect the use of aluminum corners, causing them to deform and fall off.
