SFB Beams

SFB Beams

SFB beams are easier to produce

As SFB ('Slim Floor Beam') beams have an open structure, production is simpler than with closed beams such as the top-hat and cap variant. The SFB beams produced by Mouw Hoedliggers are particularly suitable for the installation of floor panels.

  • Easier to produce
  • Suitable for floor panels
  • Fire protection not always necessary

Fire-resistant treatment not always necessary

This type of beam is made by welding a wide strip of steel under a standard profile. The heads of the hollow-core slabs then connect to the plates of the profile. To create a bond in the floor, the hollow spaces on the sides of the profile are filled with concrete. 

SFB beams do require a fire protection treatment, unless reinforcing bars are also placed in the hollow space; this already gives the structure better protection in the event of a fire. 

The torsion of an SFB beam is less strong than that of cap or top-hat beams. In some cases, this can cause problems when installing hollow-core slabs. As SFB beams are not generally exposed to considerable tensile forces, the product is made in S235 steel as a standard, unless another grade is requested.

For SFB beams, profiles from the UK UC series or the European IPE, HE-A, HE-B and HE-M beams are used.

The main advantages of SFB beams are:

  • Lightweight construction
  • Simple, but sometimes unnecessary treatment
  • Low construction height
  • Environmentally conscious
