Properties and use of ordinary structural steel sheets according to EN 10025-2
Classic sheets of non-alloy structural steel stand out for their strength, longevity and resistance to wear, which is determined by the production process. Hot rolling of sheets produces stronger and less brittle steel sheets. Their minimum yield strength starts at 235 MPa. Structural steel sheets, the technical requirements of which are specified by EN 10025-2, are suitable for all common welding processes and can be further surface-treated.
They are suitable for undemanding constructions such as bridges and footbridges, sports and industrial halls, parts of rail or motor vehicles or mining equipment. They can be used both in engineering and construction, as well as in other industries.
Choose from a wide range of sizes. We supply sheets in the following dimensions:
- length: max. 18,000 mm,
- width: 1000-3200mm,
- thickness: 5-100 mm,
- weight: max. 12,500 kg.
The stated dimensions are only approximate. The resulting appearance depends on the combination of individual parameters and material specification. Upon agreement, we are able to produce sheet metal up to a length of 21,000 mm and a thickness of 200 mm. For more information contact us.
