Zhengde U&C Channel steel is U-shaped steel Channel steel: Channel steel is a long strip of steel with a groove-shaped cross-section.
Channel steel is divided into ordinary channel steel and light channel steel. The specifications of hot-rolled ordinary channel steel are 5-40#.
Channel steel can be divided into 4 types according to the shape: cold-formed equal-edge channel steel, cold-formed unequal-edge channel steel, cold-formed inner-curled channel steel, cold-formed outer-curled channel steel
According to the theory of steel structure, the channel steel flange should bear the force, that is to say, the channel steel should stand upright instead of lying down.
Channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, and channel steel is often used in conjunction with I-beams...

Excellent characteristics
The material of the U&C channel steel is generally carbon structural steel such as 1020/C20E4/1045/E355DD, and some channel steels with special requirements are made of alloy steel. The second is the surface treatment of the channel steel. The surface treatment of channel steel generally includes painting, galvanizing, and plastic spraying to improve the corrosion resistance and aesthetics of channel steel. The last is the processing method of channel steel. Channel steel can be processed by cutting, drilling, welding, etc. to meet different usage needs.

Major application
U&C channel steel has a wide range of uses and can be used in construction, machinery manufacturing, automobile manufacturing, shipbuilding and other fields. In the field of construction, channel steel is often used to make steel structure frames, support frames, beams and columns, etc. In the field of machinery manufacturing, channel steel is often used to make machine tool beds, tracks, conveyor belts, etc. In the field of automobile manufacturing, channel steel is often used to make frame, body and so on. In the field of shipbuilding, channel steel is often used to make hull frames, ship equipment, etc.

Attention to detail
The surface quality and allowable deviation of the geometric shape of the channel steel are specified in the standard. It is generally required that there should be no harmful defects in use on the surface, and no significant torsion. The allowable value of the wave bend (sickle bend) of the channel steel and the relevant parameters (h, b, d, t, etc.) of the cross-sectional shape of the channel steel of each specification are specified. value, tolerance value. The main manifestations of the incorrect geometric shape of the channel steel are: collapse angle, leg expansion and leg merging, etc.
