construction structural steel S450J0 h beam
The S in S450J0 H-beam stands for structural steel; 450 stands for the minimum yield strength of 450 MPa (thickness ≤ 16 mm); and J0 stands for the minimum impact energy of 27 Joules at 0°C, ensuring toughness at moderate temperatures.
S450J0 construction H-beams are designed for use in structural engineering, providing high strength and stability for load-bearing applications in buildings and infrastructure.

Physical properties of S450J0 structural steel
Density: approx. 7850 kg/m³.
Modulus of elasticity (E): 210,000 MPa (according to EN 1993-1-1, Eurocode).
Thermal conductivity: ~48 W/m·K.
Coefficient of thermal expansion: 10 × 10⁻⁶ °K⁻¹ (according to EN 1994 composite structure).
These properties ensure the stability and performance of H-sections under thermal and mechanical stresses.
Applications of S450J0 steel for construction
S450J0 H-beam is widely used in construction and engineering projects that require strong structural support, including:
Building structures: main beams and columns in multi-story buildings, warehouses and industrial halls.
Bridges: main beams and supporting beams of road or railway bridges.
Infrastructure: frames of overpasses, tunnels and retaining walls.
Heavy equipment: base frames of cranes, towers and large machinery.
