This EPD represents the SWT-composite beam produced at Scandinavian WeldTech AB in Borlänge, Sweden. The SWT-beam LOW is based on recycled steel for a reduced CO2 impact. The SWT-beam is a flexible solution tailored to the customer’s needs. It enables slender and light structural solutions that provide savings in terms of volume and costs. The composite action between steel and concrete allows for creative structures with large open spaces. The SWT-beam has been used in numerous construction projects in Scandinavia since the early 1990s. The SWT-beam is a structural composite element which can be combined with all type of concrete slabs (hollow-core, massive, in-situ cast and TT-cassettes) and wooden slabs. It can rest on steel, concrete and wooden columns, but is best combined with the SWT composite column to form a unified system. SWT-beams consist of steel plates and bars welded together to form a hollow box-section, acting as a composite beam. The beam is then cast in concrete at the construction site. Typical weight of beams varies greatly between 50-500 kg/m, as each element is designed specifically to fit customer needs. This EPD is valid for an average SWT-beam project with an average material composition (production based). The quantity of materials in the product are scaled based on the product's geometry resulting in low variance of results. The EPD calculations do not cover the concrete used on the construction site. The products are CE-marked under the harmonized standard EN 1090-1 and complies with EN 1090-2. The product design is done according to european standards EN 1990, EN 1991, EN 1992, EN 1993, EN 1994 with applicable national adoptions.
