Cold-rolled materials are HRP&O rolls that have been cold reduced and annealed. The thickness has higher precision than that of an HR. Additionally, the surface is less porous and cleaner, with better forming properties. The main uses are in automotive parts, appliances, lighting fixtures, and furniture.
Galvanized steel is obtained through the hot-dip process, which allows for a continuous metallic zinc coating.
During the hot-dip process, a metallurgical chemical reaction occurs with the base steel, creating a coating with superior adhesion compared to any protective scheme. This special characteristic of the steel is directly proportional to the amount of coating, which is typically within a range of 0.4 to 0.9 ounces per square foot.
The quality of coated steel processed in Galvaprime ranges from Deep Draw grades to Structural grades for the White Goods and Industrial markets, meeting the highest requirements for surface quality.
