Custom Crete manufactures High Strength Pre-stressed Block Lintels.

Custom Crete’s lintels are manufactured with a crimped prestressing lintel wire (1550 -1700 MPa) according to SANS 1504 -1990.

The Block lintel (up to 4.5m) normally consists of 5 x 2.64mm wires. For lengths above 4.8m, 7 wires are used.

The pre-stressed wires are hydraulically tensioned and released to set standards.
