Raised floors - modular
Modular raised floors are a compatible system of panels and their supporting structure.
The boards are the most important element of the raised floor. The quality, durability and stability of the floor mainly depend on them. The material they are made of (chipboard, gypsum-fiber board, cement-fiber board) determines such parameters as: reaction to fire, fire resistance, load-bearing capacity and acoustics.
The supporting structure is selected depending on the required floor height, the purpose of the room and the resulting loads. And this is:
System I – free-standing structure
System II – structure connected with steel crossbars – traverses
System III – structure connected with a screwed steel C40 / 40 / 2mm profile
