TRAPEZ
Galvanised Concrete Trapezoid
It is the form of galvanised coils formed as trapezoidal sheet in roll forming machine. It is produced in 54/305 form. It is produced from 1200 mm sheet. Useful area is 915 mm. It is used as composite flooring panel under concrete. It acts as a mould for concrete and eliminates this cost. Compared to concrete slabs of the same thickness, it is lighter, more load-bearing and saves concrete.
Advantages
- It acts as a mould.
- Creates a safe system.
- Accelerates building construction time.
- Reduces the cost of steel and concrete.
