Hot Rolled Carbon Profile U Shaped Metal Building Steel C Channel for Construction

Channel steel belongs to carbon structural steel for construction and machinery, is a complex section of steel steel, its section shape is groove. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have good welding, riveting and comprehensive mechanical properties. The raw material billet for channel steel production is carbon bonded steel or low alloy steel billet with carbon content not more than 0.25%. Finished channel steel is delivered by hot working, normalizing or hot rolling. Its specifications to waist height (h)* leg width (b)* waist thickness (D) mm number, such as 100*48*5.3, that waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel steel, or called 10# channel steel. The channel steel with the same waist height, if there are several different leg width and waist thickness, also need to add a, B and C on the right side of the model to be distinguished, such as 25# A 25# B 25# C.
Channel is divided into ordinary channel and light channel. The specification of hot-rolled ordinary channel steel is 5-40#. The specification of hot-rolled flexible channel steel supplied by agreement of both parties is 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed cabinets, etc. Channel steel is often used with I-steel.

Angle steel, commonly known as Angle iron, is both sides of the vertical Angle into the shape of the strip of steel. There are equilateral Angle and unequal Angle. The two sides of an equilateral Angle are of equal width. Its specifications are expressed in millimeters of side width × side width × side thickness. For example, ∟30 x 30 x 3 indicates an equilateral Angle steel with 30 mm width and 3 mm thickness. It can also be represented by model, which is the number of centimeters of side width, such as ∟3#. The model does not represent the dimensions of different edge thicknesses in the same model, so in the contract and other documents, the width and edge thickness of the Angle steel should be filled in completely, so as to avoid representing by the model alone. Hot rolled equilateral Angle steel specifications for 2#-20#. Angle steel can be composed of different stress components according to the different needs of the structure, and can also be used as the connection between components. It is widely used in all kinds of building structures and engineering structures, such as beams, Bridges, transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.
