Prestressed Ribs

  • Residential
  • Commercial
  • Industrial applications

Prestressed concrete is a method for overcoming concrete's natural weakness in tension. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete.

Nominal size: 150mm wide x 60mm deep (25.0kg/m)
Wire: 4.00mm diameter (fy=1700mpa).

Concrete Strength at transfer is a minimum of 25mpa with a minimum ultimate strength of 40Mpa.
5 wire Ribs up to 4.5m
7 wire Ribs from 4.6m to 5.9m
8 wire Ribs for lengths of 6m or longer.
9 and 10 wire Ribs are available on request.
Prestressed ribs are manufactured for stock in 100 mm increments
We aim to have a minimum of 100 of each length in stock at any given time
