Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot rolled ordinary channel steel is 5-40#. The hot-rolled modified channel steel supplied by the supplier and the buyer is 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed panel cabinets. Channel steel is also often used in conjunction with I-beam.
According to the shape, the channel steel can be divided into four types: cold-bending equilateral channel steel, cold-bending unequal-edge channel steel, cold-bending inner-buckling channel steel, and cold-bending outer-rolling channel steel.
According to the theory of steel structure, it should be the force of the channel wing, that is, the channel should stand, not squat.
