EN10025-2 H-Beam
EN 10025-2 specifies the technical requirements for non-alloy structural steels (such as S235JR, S275JR, S355JR, etc.), including chemical composition, mechanical properties (yield strength, tensile strength, elongation, etc.) and delivery state (usually hot rolled).<br />
The cross section of an H Beam is "H" shaped, consisting of two parallel flanges and a vertical web.
Advantage
- High strength and light weight:
The cross-sectional design of H-beam makes it have higher section modulus and bending resistance than ordinary I-beam at the same weight, which is suitable for bearing heavy loads.
- Excellent mechanical properties:
The steel specified in EN 10025-2 (such as S355JR) has a yield strength of 355 MPa and a tensile strength of 470-630 MPa, which meets the needs of high-load structures.
- Convenient construction:
The flanges are wide and parallel, which is convenient for bolting or welding.
Standardized dimensions reduce processing time and improve engineering efficiency.
- Economical:
High material utilization rate and reduced waste.
Low long-term maintenance costs due to the corrosion resistance of steel (which can be enhanced by galvanizing or spraying).
- Stability:
The symmetrical cross-section of H-beam makes it stable under axial pressure and lateral force, suitable for seismic design
Application
- Building structures:
Frames and beams of high-rise buildings (such as commercial buildings and industrial plants).
Roof trusses and floor support systems.
- Bridge engineering:
Main beams and support structures of railway/highway bridges (anti-corrosion treatment is required).
- Industrial facilities:
Heavy equipment brackets, crane track beams, oil platform structures.
- Infrastructure:
Transmission towers, subway tunnel support, port terminals.
- Temporary structures:
Construction of temporary supports, fast-assembly buildings (such as exhibition halls).
