Cylindrical formwork for bridges - Tokai Spiral
Our cylindrical formwork is lightweight, features reinforcing ribs between the panels, has high load-bearing capacity, can be manufactured in any length, and is resistant to rust.
The cylindrical formwork of the Tokai Spiral is manufactured by winding strip steel in a spiral shape and "folding" both ends of the coil, and by adding three ribs between the folds, it ensures three times the strength without increasing the weight of the pipe, thereby enhancing reliability.
