Formwork

Tata Steel Panels and Profiles manufacture a range of four profiles which are used as permanent formwork.

Permanent formwork remains in situ for the life of the building but, unlike composite flooring profiles, it does not act as reinforcement in the concrete slab.

  • The steel decking supports the wet concrete and construction loads
  • Temporary propping can be eliminated
  • The concrete slab requires full structural bar or mesh reinforcement
  • The wide range of Tata Steel formwork profiles ensure the optimum solution is available
