Hot Rolled Carbon Steel Q195 Q235 Q345 Q235D Q275 Q275b C Channel Bar Steel U Bar for Structural Support in Construction

Steel Channel is a hot rolled, mild steel structural C shape with inside radius corners that is ideal for all structural applications, general fabrication, manufacturing and repairs. Steel Channel is widely used in industrial maintenance, agricultural implements, transportation equipment, truck beds, trailers, etc. It's C-shape or U-shape configuration is ideal for added strength and rigidity over steel angle when your project's load is vertical or horizontal. This steel shape is easy to weld, cut, form and machine with the proper equipment and knowledge. ZhengDe Metal stocks hundreds of sizes of steel channel at wholesale prices in ready to ship precut and mill lengths or you can order just what you need custom Cut to Size in small or large quantity. A-36 Steel Channel is also available in a galvanized coated finish for long lasting corrosion protection. 

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.
