Universal Column S355JR/S355J0 305x305x97 Steel Beam

UC 305×305×97 h shaped steel belongs to the British standard H-shaped steel UC series. The "305×305" in the model indicates the section size (height×width), and "97" indicates the unit weight per meter (97kg/m).

‌Sectional size‌: 305mm (height)×305mm (width), the actual weight per meter is 96.9kg/m (may be slightly adjusted due to material differences).

‌Material type‌: S355JR h steel and S355J0 steel beam are both European standard low-alloy high-strength steels, belonging to the structural steel in the EN 10025 standard.

‌Yield strength‌: ≥355MPa (both S355JR and S355J0 meet)‌.

‌Tensile strength‌: 470-630MPa (related to the material heat treatment process).

S355JR ‌h beam profile impact toughness‌: Excellent impact toughness at room temperature, suitable for low temperature environment (such as bridges, buildings in cold areas).

S355J0 ‌structural h beam impact toughness‌: The impact toughness is slightly lower than S355JR, but the welding performance is better, suitable for conventional environments (such as ships, machinery manufacturing).

‌Chemical composition‌: Mainly low-carbon and low-alloy components, containing a small amount of manganese, silicon and other elements, low carbon equivalent, ensuring good weldability and processability.

Weldability‌: Supports a variety of welding processes such as arc welding, submerged arc welding, and gas shielded welding.
‌Processability‌: Easy to cut, bend, drill and other cold/hot processing operations.

Architectural structures: high-rise building frames, beam and column supports for industrial plants.
Bridge engineering: bridge main beams and connecting parts that bear vehicle impact loads.
Ships and machinery: ship decks, load-bearing structures of mechanical equipment.
Energy and chemical industry: petrochemical equipment brackets, pressure vessel frames.
