WISA-Wire is a flooring panel coated with phenolic film imprinted with a wiremesh pattern. Panels are mainly used for construction purposes, such as scaffolding and working platforms and floors in warehouses where forklifts or pallet trucks are not used. Construction features:

Controlled loading capacity; Excellent relation weight-resistance;

Accurate dimensional tolerances; Abrasion resistance;

High number of reuses; Good resistance to alkali;

Processes: cutting, forming, drilling.

Values needed for a correct calculation of floor formwork are:

  • Floor weight in Kg per sqm
  • Distance in between transversal beams
  • Distance in between supporting beams
  • Distance in between props

The first step is to know floor weight in kg/sqm.
The next table shows floor weight expressed in square meters, formwork and live loading included.
Values indicated are approximate.
Actual values depend on floor type and thickness, iron reinforcing structure weight and formwork weight.


Once you know the floor weight in kg/sqm and you have selected the distance for transversal beams (or rather the distance on which panels rest) in the next table, compare these data in order to obtain the distance for the supporting beams (or rather the distance on which transversal beams rest).
Transversal beam maximum protrusion should not exceed 20% of the distance in between the supporting beams.


Once you know the floor weight in kg/sqm and you have selected the distance for supporting beams in the next table, compare these data in order to obtain the distance for props on which the supporting beams rest.
