Concrete beams

The pre-stressed concrete beams: time-saving for your job sites, easy and economical installation.

Bearing and strong elements

The PRECO pre-lintel is made up of a concrete beam pre-stressed by adhesive strands covered by a brick wall with the extremities cut neatly.

 

The bearing capacity of the unit is the result of the strength of the pre-lintel, the brickwork and the connection between the concrete of the pre-lintel and the mortar of the installation of the first layer of brickwork.

Easy, problem-free installation

The pre-lintels rest on a layer of brickwork that is 0.2 m long (and could be reduced to 0.1 m). It is always necessary to respect the limits of the strength of the brickwork. They are 52 mm thick and the pre-stressing strands are placed in the centre, which makes it possible to install the pre-lintels in any orientation.

 

The concrete beams come in 3 sizes: 0.09 m, 0.14 m, 0.19 m

The following lengths are available in stock: 1 m to 3,6 m, from 0.2 m by 0.2 m.

 

They are also available in any other length on request. There is an 8 day delivery period for custom lengths.
