Hot Rolled Cold Rolled
Most large or complex shapes are hot Cold formed shapes are
rolled. manufactured from plate
Shapes are created by rolling red hot Plate is cut then bent into
billets of steel in specially formed rollers shapes and welding if required
until the required shape is drawn out.
Cold formed steel is bright silver
Shapes are characterized by tight exterior in finish
corners with fillets at interior corners.
Hot rolling results in a black surface with
areas of mill slag and is generally not
suitable for exposed applications without
some treatment.
