Application and installation of floor decking

Rapid progress of building-site work

The steel floors are manufactured to the lengths specified on the order according to a slab layout plan and then delivered on pallets. The quick and easy implementation takes place in several expertly handled sequences by assembly teams

A safe working platform

The steel floor is ready to use and can be walked on as soon as it is fixed. It constitutes a working platform providing perfect safety conditions. The floors create an efficient and sealed formwork and the under side remains clean. The floor openings are placed before pouring with no need to drill the floor. The lack of an open cavity optimises safety on site

Advantages

  • Ready to install flooring with plant supplied elements
  • Fitting elements delivered from the factory
  • Form work and reinforcement works are largely unnecessary
  • Job-mixed concrete only to grout joints
  • Self-supporting spans up to 7.50m
  • Up to 60% weight saving in comparison with comparable prefabricated decking
  • Reduction of load-bearing structure costs as a result of the weight saving
  • Rapid, simple assembly
  • Decking surface is immediately usable for further processing
  • The plastic-coated underside can be used for ceilings
  • Easy drilling of the underside to fix

Design software for composite structures

Calculation softwares to optimise the resistance and rigidity of composite solutions: columns, beams, beam-to-column joints and flooring.
