SIS FORM method
When pouring concrete on the top of a bridge or road overpass, the formwork can be installed without installing a girder between the girder and the integrated formwork panel construction method that facilitates handling and freely expands or reduces the size of the formwork.
Construction
- As the process is simplified by the integration of the copper bar and the formwork, the work efficiency is increased and even the unskilled can easily and quickly perform the construction.
Safety
- This product is installed in a confined space during slab formwork and can be used as a pathway for workers to secure safety against the risk of falling.
Efficiency
- Reduced construction cost by 30% compared to the existing construction method by minimizing the number of workers and reducing costs through product reuse due to the simplified process steps

Product Features
Applicable to all bridge slabs
Transport and quick installation and disassembly are easy with an all-in-one system with copper bars and molds.
The width can be adjusted, so it can be installed and used in places where the girder spacing is not uniform.
Safety is secured by preventing the risk of falling because the operator can use it as a moving passage
