Precast Concrete Products: C1 Columns - B1 Beams (U,T or L shaped) - RF1 Roof girders (prestressed) - RF2 Roof purlins (prestressed) - S1 Side Beams

These five variously shaped precast linear concrete elements are commonly utilized in the construction of large-scale commercial and industrial buildings (forming one or several storeys), forming the main framework of the structure. While different in shape and sizes, these five types of precast linear concrete element have identical manufacturing processes and materials. All five types belong to the category of precast concrete linear structural elements and their factory production control complies with the harmonized European standard EN 13225. They bear the CE mark and are accompanied by a manufacturer-issued declaration of performance, meeting the requirements outlined in Regulation (EU) No. 305/2011. Their concrete compressive strength class is C30/37 or higher for the non-prestressed types, while C35/45 or higher for the prestressed ones.
