Shuttering magnet is a switchable magnetic fixture for prefabricated concrete element factories to fix the precast concrete formworks efficiently. This new Neodymium shuttering magnet uses strong magnetic force to fasten, move and disassembly the formwork conveniently, without bolting or welding causing any damage to the surface of the expensive formwork table. The reusable and universal use makes the shuttering magnet affordable for precast concrete plants to invest.
