S235JR Rolled C Channel Steel

S235JR channel steel is a structural steel commonly used in construction projects. It has the characteristics of high strength, good ductility and good weldability. It is an ideal material for various load-bearing structures.

Chemical composition

The chemical composition of S235JR channel beam typically includes the following elements:
Carbon (C): ≤ 0.17%
Silicon (Si): ≤ 0.60%
Manganese (Mn): 1.20% maximum
Phosphorus (P): ≤ 0.045%
Sulfur (S): ≤ 0.045%
Mechanical properties
Yield strength (ReH): ≥ 235 MPa
Tensile strength (Rm): 340–470 MPa
Elongation (A): ≥ 21%
Impact toughness: Typically tested at ambient temperature or lower, depending on application requirements.

S235JR c section steel is available in various sizes, which are typically specified by the following factors:
Height (h): The height of the channel section.
Width (b): The width of the flange.
Web thickness (t): The thickness of the vertical web.
Flange thickness (tf): The thickness of the horizontal flange.

Common sizes of S235JR channel steel include: 50x37x4.5 mm; 63x40x4.8 mm; 80x48x5.0 mm; 100x63x6.0 mm, etc. GNEE can customize larger sizes as needed.

The surface treatment of S235JR channel steel can be customized according to customer requirements: hot-rolled surface treatment (as is); galvanized coating for enhanced anti-corrosion performance; spray painting or powder coating for beautiful appearance.
