  We plan to purchase a batch of hot-dip galvanized steel sheets. Given that our previous suppliers failed to meet our material performance requirements, we have strict standards for the corrosion resistance, galvanized layer quality, and processing performance of the sheets this time. Can you provide a detailed material certificate that meets the relevant standards to ensure that the chemical composition and mechanical properties are up to standard? Can you guarantee the bending performance? We need to confirm that when the sheet metal is processed at a specific bending radius, there will be no zinc layer peeling or micro-cracks. 18/11/2025 17:43:19
