SM490 Carbon Steel H-Beams Universal

SM490 is a high-strength structural steel commonly used in the construction of buildings, bridges, and other building structures. The "SM" stands for "structural steel with specified minimum yield strength," and the number 490 represents the steel's minimum yield strength in megapascals (MPa).

Material Properties
Yield Strength: SM490 has a minimum yield strength of 490 MPa, which gives it excellent load-bearing capacity.
Tensile Strength: It has a high tensile strength, typically between 510 and 660 MPa.
Ductility: SM490 maintains good ductility, allowing it to withstand deformation without breaking.
Weldability: It has good weldability, making it suitable for building applications that require welding.

Applications
Building Construction: SM490 H-Beams are used in building frames to provide support for floors, roofs, and walls.
Bridge Construction: It is suitable for bridges, where its high strength is essential to support heavy loads.
Industrial Structures: SM490 structural H-beams are used in the construction of industrial facilities, including factories and warehouses.
Civil Engineering Projects: Used in a variety of civil engineering projects such as dams, tunnels and retaining walls.

Specifications
Shape: H-beams are characterized by their H-shaped cross-section, which provides a high moment of inertia, making them highly resistant to bending.
Sizes: SM490 H-beam universal beams are available in a variety of sizes, which are specified by flange width, beam height and web thickness.
Surface Condition: Beams are typically hot rolled and may have a rough or mill scale surface.
