S275JR
S275JR channel steel refers to a specific type of channel steel made from S275JR steel. S275JR is a commonly used non-alloy structural steel grade. It has a minimum yield strength of 275 MPa and a tensile strength of 410-560 MPa, depending on the thickness. S275JR steel contains carbon (C), manganese (Mn), phosphorus (P), sulfur (S), and silicon (Si) as its main chemical elements. Channel steel, also known as C-shaped steel or U-shaped steel, is a structural steel section with a C-shaped cross-section. It is widely used in construction, infrastructure, and manufacturing industries. Channel steel is characterized by its straight legs and a flat, perpendicular web connecting the legs.

S275JR channel steel is primarily used for structural support in various applications. It is commonly used in the construction of buildings, bridges, and other structures where strength and load-bearing capacity are required. The C-shaped cross-section of channel steel provides excellent resistance to bending and torsional forces, making it suitable for supporting loads. S275JR channel steel is versatile and can be used in a wide range of applications. It is often used in building construction for framing, bracing, and supporting structural elements.
Â
Channel steel can also be used in industrial applications for supporting conveyor systems, equipment, and machinery. S275JR channel steel is suitable for creating structural frames, supports, and bracing systems. It can be used as columns, beams, or braces to provide stability and load-bearing capacity in various structures. Channel steel is commonly used in both vertical and horizontal applications to support different types of loads.
