Cold Rolled Carbon Steel U Channel Structural U Channel With Galvanized En S235jr

These sections are manufactured from S275JR grade steel and have excellent machinability and weldability. Our stocks are available in mill finish, red oxide, or Zinc finishes to offer a range of corrosion resistance properties to suit your project. To increase corrosion resistance mild steel is normally painted or galvanized after fabrication.
Mild steel channel is widely used in civil engineering and construction to support floor joists and to weight bear above window and door gaps where the structural load does not require an I beam.
Channel steel is a long strip of steel with a groove-shaped cross-section. It is a carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

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.
