Steel beams
Steel beams are used as individual load-bearing vertical or horizontal elements (as beams, lintels, etc.); or as part of a complete steel construction. Steel beams produced since the 1970s meet modern product specifications. To determine their suitability for reuse, there are now several concrete guides (see references in the material sheet). Most demolition contractors selling reuse material have a stock of beams of the most common structural steel grades.
