Information about the formwork beam

Zur deutschen Version
Icon Feder mit gelbem Kreis

High load capacity.

Reliably high load capacity across the entire beam length thanks to homogeneous web material. According to EN 13377.

Icon Feder mit gelbem Kreis

Security & high stability.

Secured component load capacity, as all of the flanges are machine stress-graded and load-tested. Consistent product characteristics owing to high dimensional stability.

* In accordance with EN 12812, this allows for a service load of 0.75 kN/m2 and a variable load of 10 % of a massive concrete floor-slab, totalling at least 0.75 kN/m2 but no more than 1.75 kN/m2 (assuming a fresh-concrete density of 2 500 kg/m3). Mid-span deflection has been limited to l/500. In the case of cavity flat-slab floors, significantly lower slab loads occur.
** the secondary beams in accordance with the type of formwork sheeting (load-bearing capacity and sheet format) that has been chosen.
Form-on beam to EN 13377. Form-on prop with a permitted loading capacity of ≥ 20 kN.
