U-Channel steel is a long strip of steel with a groove-shaped cross-section. It belongs to carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. U-Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.
basic situation
In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billet for producing channel steel is carbon structural steel or low alloy steel billet with carbon content not exceeding 0.25%. The finished channel steel is delivered in the state of hot forming, normalizing or hot rolling. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means that the waist height is 100 mm, the leg width is 48 mm, and the waist thickness is 5.3 mm. Steel, or 10# channel steel. For channel steel with the same waist height, if there are several different leg widths and waist thicknesses, a b c must be added on the right side of the model to distinguish them, such as 25#a 25#b 25#c, etc.
Classification
U-Channel steel is divided into ordinary channel steel and light channel steel. The specifications of hot-rolled ordinary channel steel are 5-40#. The specifications of the hot-rolled flexible channel steel supplied by agreement between the supplier and the buyer are 6.5-30#. U-Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed cabinets, etc. U-Channel steel is often used in conjunction with I-beams.
U-Channel steel can be divided into four types according to the shape: cold-formed equal-edge channel steel, cold-formed unequal-edge channel steel, cold-formed inner-curled channel steel, and 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.
specification setting
The specifications of channel steel are mainly represented by dimensions such as height (h), leg width (b), waist thickness (d), etc. The domestic channel steel specifications range from No. 5 to No. 40, that is, the corresponding height is 5 to 40cm.
At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. No. 18-40 is a large channel steel, and No. 5-16 channel steel is a medium-sized channel steel. The imported channel steel indicates the actual size and relevant standards. The import and export order of channel steel is generally based on the specifications required in use after determining the corresponding carbon steel (or low alloy steel) steel grade. Channel steel has no specific composition and performance series other than the specification number.
The delivery length of channel steel is divided into two types: fixed length and double length, and the tolerance value is stipulated in the corresponding standards. The length selection range of domestic channel steel is divided into three types: 5-12m, 5-19m, and 6-19m according to different specifications. The length selection range of imported channel steel is generally 6-15m.
Zhengde U&C Channel steel is a long strip of steel with a groove-shaped cross-section. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 120*60*5.5, which means that the channel steel with a waist height of 120 mm and a leg width of 60 mm has a waist thickness of 5.5 mm. mm channel steel, or UPE120 channel steel.
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.

Our Advantages
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.
