3. ADVANTAGES

- true to size and dimensionally stable solid web girder - time- and cost-saving in processing - long durability due to high quality gluing - protection against damage by special design of the beam ends - low weight (4.80 kg/running meter) - adaptable and versatilely applicable - unproblematic disposal - quality supervision by MPA Stuttgart

4. CHARACTERIZATION OF THE BEAM

- manufacturer's name: HIS - EN 13377 - class of beam P, supervision level M - supervisory board MPA Stuttgart - coded identification data of production

5. REGULATIONS FOR APPLICATION AND STORAGE

The quoted calculation values must not be overwritten. The formwork is to be nailed down directly onto the upper chord. The timber formwork beams are to be secured against tilting according to the static requirements. Before each use of the timber formwork beams they are to be checked for good order and condition by the assembling company. Damaged or putrefactive weakened beams must not be used. During the storage of the beams should be noted that these are not being exposed to strong climatic influences for too long, and they are not to be stored outdoors.
