Thicknesses and weight
| Nominal thickness (mm) | Min. thickness (mm) | Max. thickness (mm) | Weight (kg/m²) | n° of layers |
|---|---|---|---|---|
| 18 | 17,8 | 18,2 | 9,81 | 11 |
| 21 | 20,8 | 21,2 | 11,45 | 13 |
Panel size
2440×1220 mm or 2500×1250 mm
Size tolerances
± 1 mm – The panel can have dimensional changes due to changes in the air humidity.
End uses
Usage mainly for slab forms. Typical number of reuses is likely to be about 5 -10 times. However the number of reuses will depend on a wide range of factors including good site practice, the required con-crete finish, careful handling & storage of forms and the type and quality of release agent.
