The main distinctions of painted steel straps in the industry can be classified from three aspects: manufacturing accuracy, tensile strength and surface condition.
According to the manufacturing precision, the code of the coated steel strap with the thickness of ordinary precision is PT·A; the code of the steel strip with the higher precision of thickness is PT·B; the sickle bend is the painted steel of ordinary precision The belt code is PS·A; the sickle bend is the higher precision steel belt code is PS·B.
can be divided into groups Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ, Ⅶ according to the tensile strength. Groups Ⅰ and Ⅱ are low-strength steel straps; Groups Ⅲ and Ⅳ are medium-strength steel straps; Groups Ⅴ, Ⅵ and VII are high-strength steel straps.
Of course, the surface condition of the painted steel strip is different, we can divide it into three types: the blued steel strip is SBL; the painted steel strip is SPA; the galvanized steel strip is SZE.
Of course, in terms of the size and scale of painted steel straps, short steel strips with a thickness greater than 0.5mm are allowed to have 1 joint in each coil, and short steel strips with a thickness of not more than 0.5mm are allowed to have 2 joints in each coil. , The length between joints is not less than 20m. Short steel strips should be delivered separately.
