These are thermomechanically rolled sheets with a fine-grained structure. Their quality, requirements for processing and properties are governed by regulation EN 10025-4. Common structural steel sheets according to EN 10025-4 are characterized by excellent weldability, strength and resistance. You can also use them for more demanding industrial or construction structures that are heavily stressed.

Properties and use of ordinary structural steel sheets according to EN 10025-4
Fine-grained structural steel sheets stand out for their increased toughness especially at low temperatures (impact tests at −50 ℃), excellent weldability and mechanical strength, which is determined by the production process, specifically by thermomechanical rolling. It results in synergistic effects, such as increasing the strength of the material without losing toughness. Structural steel sheets, the technical requirements of which are specified by EN 10025-4, are suitable for bending, crimping, edging and cold edging.
Their properties guarantee efficient processability and offer a wide range of uses. Common structural steel sheets according to EN 10025-4 are suitable both for demanding steel constructions and as load-bearing elements. You will use them in heavily loaded parts of welded structures, for example in the construction of bridges, the production of pipelines or for storage or water tanks. They find their use in many 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.
