Multi-storey car parks made in steel18 September 2016
The "open front" system guarantees abundant natural ventilation, which is fundamental to safety in the event of fire: records in Europe show that with the advanced structural calculation methods set forth by Eurocodes, it is possible to guarantee structural safety in the event of a fire, thus eliminating or reducing the need for expensive fire safety systems for metal structures.Article
Cofraplus® 220 combines the outstanding resistance of the patented steel profile with the performance of a ribbed reinforced concrete slab. The total load bearing capacity results as the sum of the resistance of both elements, as no composite action is taken into account.
The high values of moment of inertia and bending moment guarantee large span without propping.
Cofraplus® 220 sheets are available with thicknesses of 1, 1.13 and 1.25 mm, with a maximum length of 9 m.
