MULTIFLEX Girder Slab Formwork

The flexible and adjustable slab formwork with GT 24 Formwork Girder
The flexible and adjustable slab formwork with VT 20K or GT 24 Formwork Girder
MULTIFLEX can be adapted to suit all ground plans. The overlapping of the slab girders and change of direction of the main beams ensure maximum fl exibility.
With the PERI MULTIPROP, the high permissible GT 24 support reaction of 28 kN can also be used with maximum extension lengths.
14.00 m high PERI UP birdcage scaffolding as load-bearing substructure for the MULTIFLEX girder slab formwork.
The use of the GT 24 Latice Girder as a twin main beam, in connection with PERI UP Flex Shoring, facilitates the transfer of heavy loads over great heights.
The Flexclip is available for three different girder combinations. The additional component ensures tilt-resistant connections of the girders without any nailing.


The main components of the MULTIFLEX are the VT 20K or GT 24 Formwork Girders. As the main and cross beams, their position and spacing as well as the formlining can be freely selected, MULTIFLEX provides maximum flexibility for a wide range of requirements. If the high load-bearing GT24 Formwork Girders are used, large spans for the main and cross beams can be realized. MULTIFLEX is therefore the ideal solution for complicated ground plans, slabs with offsets
or integrated downstand beams, as well as forming operations in confined spaces.

Optimized use of materials
through any combination of GT 24 and VT 20K Formwork Girders as well as a freely selectable girder arrangement

For all ground plans
through the variable positioning of the girders –  also polygonally or overlapping

For all surface requirements
with freely selectable formlining for the stipulated quality and adaptable to suit the required joint arrangement

Technical Details

  • Girder slab formwork consisting of main and cross beams for the formlining of choice
  • Project-specific selection of the formwork girders and their spacing
  • For slab thicknesses of up to 100 cm with GT 24 Formwork Girders, for slab thicknesses up to 50 cm with VT 20K Formwork Girders
  • Adapting the individual component weights in accordance with the boundary conditions
  • Free choice of shoring
  • No infill areas due to project-specific planning
  • Tilt-resistant support of the cross beams on the main beams through the use of Flexclips
