Preform System

The metal formwork system with a Preform frame is composed of modular elements with a galvanised steel structure which, together with a vast range of accessories and special sub-systems, enables the implementation of infrastructural works, such as: walls, pillars and foundations, beams and slabs, tanks, silos, refrigeration towers, dams, pre-compressed beams, selfsinking tanks, piles and decking for bridges and viaducts, tunnels, pipes and channels

Formworks: Frames of S235JR and S335JR hot dip galvanized steel profiles
• 18-mm multi-layer birch panels with 250 g/msq phenol coating
• Accessories: Steel grade S235JR and S355JR hot dip galvanized

• Modularity
• Fully accessorized, wide interchangeable accessories range
• Wide range of re-use possibilities
• Anchorage using bars inserted in conical sleeves that enable the assembly of inclined opposed panels or panels placed on surfaces at different heights
• Beams with Omega profiles with button holes that enable the fast and safe insertion of accessories such as props and casting bracket
