Material Excellence - S275JR
S275JR is a low carbon manganese steel widely used in structural engineering. Its yield strength of 275 MPa (minimum) ensures reliable performance in static loading conditions. The steel offers excellent toughness and ductility, allowing it to absorb energy without brittle fracture. This makes it particularly suitable for regions with low ambient temperatures. Additionally, the chemical composition of S275JR provides good resistance to corrosion when properly surface treated.
Manufacturing Process and Quality Control
The H beams are produced using advanced hot-rolling technology. We implement a strict quality management system certified under ISO9001. Each production batch undergoes dimensional inspection, mechanical testing, and surface quality checks. Our technicians use calibrated instruments to verify web thickness, flange width, and straightness. The results are documented and traceable to ensure full accountability. This meticulous approach guarantees that every beam meets or exceeds the requirements of structural applications.
Applications
The Universal Steel H Beam 300x300x10x15 mm is an ideal choice for:
- Building Construction: Columns, main beams, and secondary support structures.
- Industrial Facilities: Factory frames, workshops, and storage racks.
- Bridge Engineering: Girders and crossbeams.
- Machinery Manufacturing: Equipment bases and frames.
- Infrastructure Projects: Power plants, terminals, and logistics hubs.
Surface Treatment and Finishing
In the default condition, the beam retains its black steel finish. For enhanced corrosion resistance, we offer surface treatments such as shot blasting and galvanization. This is available upon request and can significantly prolong the service life in outdoor or high-humidity environments. We also provide custom painting to match specific project specifications. Please contact our sales team to confirm the available options and lead times.
Packing and Loading
To prevent damage during transportation, the H beams are bundled with steel straps and protected with end caps or waterproof wrapping. We coordinate loading using cranes and ensure balanced weight distribution in containers or bulk vessels. For breakbulk shipments, beams are stowed on dunnage to avoid contact with moisture. Our logistics team is experienced in handling both container and bulk cargo to diverse global ports, including Qingdao Port.
