UB 254x146x31 254x146x37 S355JR steel h profile
1. Material Overview
S355JR is a common low-alloy high-strength structural steel that complies with European standard EN 10025 and is widely used in construction, bridges, machinery and equipment, and shipbuilding.
Yield strength: ≥355 MPa.
Tensile strength: 470-630 MPa.
Elongation: ≥21%.
Toughness: Good low-temperature impact resistance.
Chemical composition: low carbon, low sulfur and phosphorus, containing a small amount of alloying elements (such as manganese and silicon) to enhance strength and toughness.
2. UB steel specifications
UB 254x146x31 h section beam
Height: 254 mm
Wing width: 146 mm
Web thickness: 31 mm
UB 254x146x37 steel h beam
Height: 254 mm
Wing width: 146 mm
Web thickness: 37 mm
The main difference between UB 254x146x31 and 254x146x37 h beam structures is the web thickness. The thicker the web, the stronger the bending resistance of the steel, but the weight also increases accordingly.
3 Performance characteristics
High strength: UB steel has high yield strength and tensile strength, suitable for structures with large loads.
Good weldability: S355JR material is easy to weld and suitable for on-site construction.
Corrosion resistance: Low alloy composition makes it have certain corrosion resistance, suitable for humid or mildly corrosive environments.
Lightweight design: The H-section design reduces weight while providing high strength, making it easy to transport and install.
4 Typical Applications
UB 254x146x31 and UB 254x146x37 h-shaped steel have excellent mechanical properties and are widely used in the following fields:
Building structures: such as beams, columns, support systems, etc.
Bridge engineering: used for crossbeams and longitudinal beams of bridges.
Machinery manufacturing: as structural parts of mechanical equipment frames.
Shipbuilding: used for structural support of hulls and decks.
