Hot Rolled

Hot Rolled


This flat rolled steel produced from a slab which is put through the mill work rolls to determine the final thickness while at high temperatures.

Typical uses for Hot Rolled Steel

Automotive, truck frames, automotive wheels, pipes and tubular, water heaters, agriculture equipment, compressor shells, truck frames, railcar components, wheel rims, metal buildings, tippers, trailers, doors, shelving, wheel rims, discs, guard rails, pipe and tubular & automotive components

Formability

Hot Rolled Sheet is used for a wide range of applications, from simple bends to complex draws or structural applications that require a specific strength level. The steel grade and processing technique of the metal are important in order to meet the customer requirements.
