At first glance, the aluminum profile, thickness, strength and oxide film used for high-quality aluminum alloy anti-skid plate shall comply with the relevant national standards. The wall thickness shall be more than 1.2mm, the tensile strength shall reach 157 Newtons per square millimeter, the yield strength shall reach 108 Newtons per square millimeter, and the oxide film thickness shall reach 10 microns. If the above standards are not met, it is inferior aluminum alloy and cannot be used.

Second, look at the processing. The high-quality aluminum alloy anti-skid plate has fine processing, exquisite installation, good sealing performance and free switching. For inferior aluminum alloy doors and windows, aluminum profile series and specifications are blindly selected, and the processing is rough. Sawing is used instead of milling. They are not installed according to the requirements, with poor sealing performance and uneasy opening and closing. Not only air and rain leakage and glass cracking occur, but also in case of strong wind and external force, it is easy to scrape or bump off the push-pull part or glass, and destroy objects and hurt people.

Third, look at the price. In general, due to the high production cost, the price of high-quality aluminum alloy anti-skid plate is about 30% higher than that of low-quality aluminum alloy anti-skid plate. At present, there are many self-employed people processing aluminum alloy anti-skid plates. They do not understand the structural characteristics and performance of aluminum alloy anti-skid plates. In order to reduce costs, shoddy work and materials, shoddy products have great hidden dangers, which are generally not suitable for use. It is best to choose the products of regular aluminum alloy anti slide plate manufacturers
