S355JR S355J0 254x146x31 hot rolled h profile steeel
Basic parameters of 254x146x31 steel beam h
Section height (h): about 254 millimeters (mm)
Flange width (b): about 146 millimeters (mm)
Weight per meter: about 31 kilograms (kg)
Material and characteristics of 254x146x31 h type steel beam
S355JR material h beam is suitable for general structural purposes.
Yield strength: at least 355 MPa (at room temperature)
Tensile strength: 470-630 MPa
Impact energy (20℃): at least 27 J
S355J0 h type beam is suitable for structural applications in low temperature environments.
Yield strength: at least 355 MPa (at room temperature)
Tensile strength: 470-630 MPa
Impact energy (0℃): at least 27 J
The main difference between the two materials is the difference in the minimum impact test temperature. S355J0 can maintain good toughness at lower temperatures.
Application scope of 254x146x31 h shaped steel beam
Due to its large cross-sectional size and high strength, this specification of H-shaped steel is usually used in the following fields:
Large building frame: provides strong support, suitable for high-rise buildings or large-span structures.
Bridge construction: used in key parts such as piers and main beams to ensure the safety and stability of the structure.
Heavy equipment foundation: provides solid foundation support for industrial equipment.
Infrastructure projects: such as railway track laying, highway construction, etc.
