Mega Prefab's preslab is a solid precast slab, which is pre-stressed to provide excellent span/ ratio depth. The standard slab width is 1200mm and available in depths of 60, 80, 100, 125, 150 and 175 mm depths. the Preslab is often used with a structural topping, to aid stability of the structure and increase its load capacity. Maximum spans are about 8.5m, depending on loads.
The Pre-stressed Preslab and the HollowCore Slab have the same fair-face finishing from below, the pre-slab is advantageous when used to bear very high live load or for cases where the slab needs to distribute live loads.
