What are the mechanical properties of color steel plates, how much do you know? Next, I will give you a brief introduction based on my long-term experience and information. I hope it will be helpful.
The forming and processing performance of the color steel plate depends on the mechanical properties of the substrate and the performance of the coating. The performance of the coating, such as thickness, gloss, solvent resistance, hardness, reverse impact, etc., has a very strict set in the color coating process. Detection and control methods.
Therefore, the mechanical properties of color steel plates actually refer to the mechanical properties of the substrate. According to the steel plate grades specified in my country, there are many types of substrates that can be used for color coating, and they all have different mechanical properties. Therefore, the selection should be based on The use, processing method and degree of deformation of the color-coated board are selected.
According to the recommendation of GB/T 12754-2006, the printed color steel plate used for building roofs usually chooses the DC51D series of grades. For components with load-bearing requirements, suitable steel structures such as S350GD and S550GD series grades should be selected as base plates according to the strength requirements. For processing color-coated plates with large deformation such as shearing, bending, and rolling, the substrate should be made of better-shaped materials, such as DC520D, DC530D series of grades.
