SM490 C-Channel Steel Beam
SM490 channel steel size specifications: Common sizes are 75×40 mm, 100×50 mm, etc., and specific sizes such as web thickness, flange thickness, and length can be selected according to different needs.
Product features of SM490 c section steel
Good weldability: easy to weld with other steel components, convenient for on-site construction and installation.
Good cold formability: can be formed by cold processing methods such as bending and stamping, which can meet the processing needs of various complex structures.
High strength: high strength, can withstand large loads, and can meet the needs of different engineering structures.
Chemical composition of SM490 channel c steel
SM490A carbon (C): ≤0.20% when thickness ≤50mm, ≤0.22% when 50mm＜thickness ≤200mm
SM490B carbon (C): ≤0.18% when thickness ≤50mm, ≤0.20% when 50mm＜thickness ≤200mm
SM490C, SM490YA/YB carbon (C), ≤0.18% when thickness ≤100mm.
Silicon (Si): ≤0.55%
Manganese (Mn): ≤1.60%
Phosphorus (P): ≤0.035%
Sulfur (S): ≤0.035%
Application areas of SM490 c channel steel
Construction field: widely used in building structures such as bridges, industrial plants, high-rise buildings, warehouses, etc., can be used as beams, columns and other components to bear the weight of the building and various loads.
Transportation industry: used in the manufacture of ships, locomotives and truck frames.
Petrochemical industry: can be used to manufacture oil storage tanks, conveyors and other equipment.
Surface treatment of SM490 c channel
Blackening: The surface forms a natural oxide layer during hot rolling, which has a certain protective effect, but the appearance is relatively rough.
Galvanizing: A layer of zinc is plated on the surface of the steel to form a protective film, which can effectively prevent the steel from rusting and extend its service life.
Primer coating: Primer is applied to the surface to improve the adhesion of subsequent coatings and enhance anti-corrosion performance.
