These are sheets with a fine-grained structure. Their quality, requirements for processing and properties are governed by regulation EN 10025-3. They are characterized by high toughness and good weldability. You can also use them for more demanding industrial or construction projects and the construction of railway or motor vehicles.
Properties and use of ordinary structural steel sheets according to EN 10025-3
Fine-grained sheets of unalloyed and alloyed stainless steel are distinguished by increased toughness especially at low temperatures (impact tests at −50 ℃), lower sensitivity to material aging or brittleness and good cold formability which is determined by the manufacturing process = normalizing annealing or normalizing rolling. Their minimum yield strength starts at 460 MPa. Structural steel sheets, the technical requirements of which are specified by EN 10025-3, have a fine-grained structure thanks to the low carbon content and microalloying elements.
Their structure together with high purity guarantees excellent properties, thanks to which you can use the sheets in various applications. It is suitable for demanding constructions and as load-bearing elements. You will use them in heavily loaded parts of welded constructions, such as bridges, floodgates or storage or water tanks. They are also suitable for the production of railway and motor vehicles.
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 sheets up to a length of 21,000 mm and a thickness of 200 mm.
