Product standard
Industrially manufactured wooden formwork beams are intended for use in load-bearing scaffolding and formwork in concrete construction. Loads are applied to them in the direction of the beam height. EN 13377 specifies the classification, requirements, and test methods for formwork beams with construction heights h = 16 cm, h = 20 cm, and h = 24 cm. In Germany, the H20 standard DIN EN 13377 is valid in conjunction with DIN 20000-2. According to regulations in Germany, it is marked with the letter “Ü”.
