S355JR/S355J0 UB 1016*305*393 Universal Steel Beam

S355JR h steel profile: This is a non-alloy high-strength structural steel defined in the EN 10025 standard with good welding and mechanical properties, suitable for structures subject to medium loads. Its yield strength is 355 MPa and its tensile strength range is 470-630 MPa.

S355J0 steel beam: Similar to S355JR h shaped beam, but with higher low-temperature toughness and suitable for more demanding environments. Its yield strength is also 355 MPa, but the tensile strength range is the same.

Equal flange width: The width of the upper and lower flange plates is the same, but the thickness may be different.
Short section height: The design focuses more on bending and shear performance, suitable for beam structures subject to bending moments.

Section height: 1016 mm
Width: 305 mm
Web thickness: 39.3 mm
Flange thickness: may vary depending on the specific model.
The size design of UB steel focuses on the balance between strength and stiffness, and is suitable for structures subject to bending and shear loads.

High strength: Yield strength ≥355 MPa, able to withstand large loads.
Good toughness: S355J0 material has higher low-temperature toughness, suitable for cold areas or impact load environments.
Weldability: Both materials have good welding performance and are suitable for a variety of welding processes (such as manual arc welding, submerged arc welding, etc.).
Processing performance: easy to cut, bend and form, suitable for the manufacture of complex structures.

Building structure: used for load-bearing components such as beams, columns and trusses.
Bridge engineering: used as the main beam or auxiliary beam of the bridge to enhance the bearing capacity and stability of the structure.
Machinery manufacturing: used to manufacture beams and supporting structures in mechanical equipment.
Road construction: used as beam structure of highway or railway bridges.
Shipbuilding: used for beams and frames in hull structures.
