Is channel steel cold rolled or hot rolled?
Belong to hot rollingThe raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.
Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-30#. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed plates, cabinets, etc., and channel steel is often used in conjunction with i-beam.
According to the theory of steel structure, it should be stressed by the channel plate, that is to say, the channel should stand rather than lie prone.
According to the channel shape and can be divided into 4 kinds: cold bending equilateral channels, cold-formed non equilateral channel steel, cold rolled edge channels, the cold bending edge channels
