Steel structures

This LCA study is developed for steel structures such as columns, beams, trusses, braces and bonds and embedded fixtures made in conformity with the EN 1090 standard; structural steel and steel components as well as for kits placed on the market as construction products. It also covers steel components used in composite steel and concrete structures. Steel components can be used directly, in construction work, or as structural components in the forms of kits. The EN 1090 standard does not cover components for suspended ceilings, rails or sleepers for use in railway systems. Thus, these product types are not comprised by this LCA study. Steel structures are manufactured from different steel components. They may be produced from sections/profiles with various shapes or flat sheets. The process requires electricity ang gases. These steel structures are cut, drilled, and assembled according to customer’s drawings, welded with welding wires and painted. Constructions are produced in various sizes and shapes. Detailed technical data is delivered with every product delivery with a declaration of performance (DoP).
