1: S235 steel introduction
Structural steel is a standard construction material made from specific grades of steel and formed in a range of industry-standard cross-sectional shapes (or 'Sections'). Structural steel grades are designed with specific chemical compositions and mechanical properties formulated for particular applications.
There are many examples of European grades of structural steel - for example, S195, S235, S275, S355, S420, and S460. But S235, S275, and S355 are three common structural steel grades used in all manner of construction projects across the EU.

Application	Structural steels are used in many ways and their application can be diverse. They are particularly useful because they offer the unique combination of good welding properties with guaranteed strengths. Structural steel is an extremely adaptable product and is often favored by engineers trying to maximize strength or 'S' structure while minimizing its weight. It will come as no surprise that the construction industry is the biggest consumer of structural steel, where it is used for a number of purposes. Whether a small box lintel is used to carry the load of a structural wall in a residential property or a vast I-beam is bolted in place to hold the road surface on a bridge, structural steel can be specified, designed and fabricated for any type of job.
