General construction refers to all the construction activities related to steel infrastructure for building, so it covers a very wide range of applications. General construction mainly includes a wide range of frames and beams of various types and shapes for buildings and bridges. For the vast majority, C-Mn steels such as S 235 to S460 grades are used, but this is also a typical application for weather-resistant steels. Of course, structures can also be made with other metal alloys such as aluminium and stainless steel. Typical thicknesses range from medium to heavy so productivity combined with excellent quality is a key factor.
