SS400 S235JR U Channel Steel

EN S235JR steel grade equivalent table:

Roll shaping a sheet or strip of metal produces metal channels. Roll forming is the process of continuously bending a metal strip as it goes between a series of rollers, also known as supports, that distort a piece of the metal until the required shape is attained. After the shaping and configuring is completed, the formed parts are cut to the desired lengths. Roll forming is a low-cost method for mass-producing parts that don't require any extra processing or finishing. Roll forming allows for the creation of an infinite number of metal channel profiles.

Steel Hot Rolling Process

Hot rolling is a metalworking procedure that takes place above the material's recrystallization temperature. Mechanical properties of hot rolled metals are generally unidirectional, and deformation-induced residual stresses are common. Non-metallic inclusions, on the other hand, can sometimes transmit directionality. Non-uniform cooling causes many residual stresses, common in shapes with non-uniform cross-sections like I-beams and H-beams.
