The reasonable selection of pre painted galvanized steel coil can not only meet the use requirements of the demanders, but also reduce the costs to a greater extent. If the selection of materials is not appropriate, the results may cause the data function to exceed the use requirements, form unnecessary waste, or fail to meet the use requirements, deteriorate or become unusable. Therefore, those who need it should attach great importance to the rational selection of color coated rolls, and consult professional product experts if necessary.
The overall basis for color coating material selection is mechanical function, substrate type, electroplating composition, surface coating function, screening of coating function, application, use environment corrosion, life, durability, processing method, degree of deformation are color coating material selection Important factor. Color coating roll mechanics function options: one is to screen according to factors such as use, processing method, deformation degree and so on. The general deformation methods of color coating are shearing, refraction, rolling, and mechanical functions. According to the color coating process, the storage time will also change, which is easy to cause creases in processing.\
The type of substrate of the pre painted steel coil and the selection of the plating composition of the color coating roll: mainly based on the use, the corrosiveness of the use environment, the service life, the durability and other factors. Anti-corrosion is one of the main functions of color coating rolls. The type of substrate and the composition of the plating layer are the factors that affect the corrosion resistance. The color coating board for construction generally chooses galvanized substrates and aluminum-zinc alloy substrates. A substrate with good corrosion and a large composition of the plating layer. In addition, the substrate that should be paid attention to when selecting theprepainted steel coils substrate.
