What is the difference between a hot dipped galvanized steel coil and a cold roll coil?
Compared to cold-rolling, hot-rolled steel has higher yield strength and less grain deformation, because the cold-rolling squashes the steel so that the microscopic “grain structure” resembles an oval shape. Cold-rolled steel has superior directional strength, which is valuable for certain high-load applications
