The basic classification of channel steel is two types, one is ordinary channel steel, and the other is light channel steel, and the general channel steel specifications are 5-40 #. The specifications of hot rolled modified channel steel provided by suppliers and buyers are 6.5-30 #. Channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures and fixed cabinets. Channel steel is also often used with I-beams.
According to the shape, channel steel can be divided into four types: cold-rolled equilateral channel steel, cold-rolled unequal channel steel, cold-rolled internal pressure channel steel, and cold-rolled external rolled channel steel. According to the steel structure theory, they should be channel steel wings The force, that is, the channel should stand, not squat.
The basic situation requires the use of good welding, riveting performance and comprehensive mechanical properties. The raw material billet of the channel steel is carbon steel or a low alloy steel billet having a carbon content of not more than 0.25%. The finished channel steel is hot-formed under normal or hot-rolled conditions: the specifications are expressed by waist height (h) * leg width (b) * waist circumference (d), such as 100 * 48 * 5.3, which means that the groove height is 100 mm and the leg width It is 48 mm, and the waist is 5.3 mm thick. Steel or 10 # channel steel. If the waist height is the same, if there are many different leg widths and waist thicknesses, you need to add abc on the right side of the model to distinguish it, such as 25 # a25 # b25 # c.
