What are the Accuracy grades of aluminum profiles? By Ruiqifeng Aluminum Aluminum profiles, like other materials, have national standards. There are strict standards for the appearance, geometric tolerance and mechanical properties of aluminum profiles. Among them, the standard of industrial aluminum profile is GB/t6892-2015, and the national standard of architectural aluminum profile is GB/t5237-2017. each standard is divided into three levels, ordinary level, high-precision level and ultra-high-precision level. Ruiqifeng aluminum profile is generally implemented according to the high-precision standard of GB/t5237-2017, but the internal control standard is more strict, and even reaches the ultra-high-precision standard. After all, the production process of aluminum profile is extrusion process. Even if it reaches the standard of high-precision or ultra-high precision, its tolerance still cannot meet the requirements of precision parts, such as bending, torsion and concentricity, which require post-processing, milling, turning and other processes to meet the specific requirements. For materials that do not require high precision, such as doors and windows, partitions, and aluminum profiles of equipment frames, high precision is enough.
