Baosteel colour coated steel sheet TDC51D

Coating thickness shall be not less than 20 microns, the special requirements of coating thickness is to be negotiated with orders, mechanical performance is mainly based on the application, processing method and the deformation degree of factors to choose. Demand is not high in strength, deformation is not complex, caitu TDC51D, TDC52D series can be used. When have higher request for formability should choose TDC53D, caitu TDC54D series. For component load-bearing requirements, should choose the appropriate structural steel according to design requirements, such as TS280GD caitu, TS350GD series. Shear, bending, rolling, etc is width, the commonly used processing methods, the order should be based on the characteristics of each processing method. Actual production often use mechanical properties of substrate instead of width, mechanical properties, and MCL process may result in changes of mechanical properties of the substrate. In addition, the mechanical properties may also change along with the increase of storage time. Caitu when processing forming these will increase the flow belt or the possibility of crease, main types of substrate and coating weight according to the purpose for the first time, using the environment corrosion, factors such as overhaul life and durability. Corrosion is one of the main function of the width, the types of substrate and coating weight is the main factor affecting the width, corrosion resistance. Building caitu is usually selects the hot dipped galvanized substrate and hot plating aluminum zinc alloy substrate, is mainly due to both the substrate has good corrosion resistance. Zinc plating zinc base plate technology limited, usually thin, relatively poor corrosion resistance, and the production cost is higher, so rarely used. Coating corrosion to determine the weight should be according to use environment, should be used in high corrosive environment good corrosion resistance and weight coating substrate, to ensure that meet the first overhaul life and durability. In addition, choosing base board should also pay attention to the differences of all kinds of substrate corrosion resistance of incision.
