Steel grade touches on the load capacity, span and the structure distribution requirements of construction. Thus users always consider about the specific steel grade according to design requirements when buy the galvanized steel sheet. On the basis of tensile strength, galvanized steel can be divided into 280MPA, 340MPA, 400MPA, 540MPA and full hard board.
The intensity of prepainted galvanized steel sheet relies on the substrate. Therefore, their intensity can reference to the data of substrate. And some enterprises also divide according to CQ, DQ, HSS and FH. But the factory technician in CAMELSTEEL thinks that the final choice of intensity should depend on the user’s requirements. In particular, the corresponding yield strength, tensile strength, elongation and other important indicators. With the use experience and the actual needs of users all gradually same to most of the steel material. Prepainted galvanized steel plate also develop to the medium and high strength.
The galvalume steel substrate is accepted by more users in recent years. Due to the different performance of zinc and aluminium under acidic and alkaline conditions, it is recommended to use the prepainted galvanized steel sheet with galvalume steel substrate in acidic conditions and galvanized steel substrate in alkaline conditions.
