· Structural shapes like I beams are usually hot rolled The formula of steel used for I beams is different than used in cold forming It s less ductile and harder which makes it tougher to bend cold hence the use for structural shapes that carry a lot of weight Cold roll forming has many commercial and industrial uses

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi finished steel slabs of steel nearly to their melting point then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77 000 hp and finally coiling up the lengthened steel sheet for transport to the next process

The hot dip galvanizing process is highly versatile and articles ranging in size from nuts and bolts to long structural sections can be coated This range together with the ability to bolt or weld fabrications after galvanizing allows almost any size of structure to be hot dip galvanized

Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal typically steel into products such as structural steel I beams angle stock channel stock and so on bar stock and rails Most steel mills have rolling mill divisions that convert the semi finished casting products into finished products
