Custom Crete manufactures High Strength Concrete Rib Beams which are a component of its Engineer approved Rib and Block Flooring System.
The Rib Beams are an integral component of the Rib and Block system.
Custom Crete’s lintels are manufactured with a crimped prestressing rib beam wire (1550 -1700 MPa) according to SANS 1504 -1990.
Each Rib Beam contains 5 x 5mm diameter pre-stressed wires, which are prestressed to approximately 75% of their ultimate tensile strength (UTS).
The Rib Beams are manufactured with shear connectors (made from 6mm round bar) placed at approximately 800 / 1000mm.
