Which joist should I choose for my terrace: wood or aluminum?

The choice of joist determines the stability and the sustainability of your terrace, but also the ease of implementation. This is why we recommend the concept of STRUCTURAL® aluminum joist designed to last and simplify installation.

1. Durability and stability

The joists STRUCTURAL® aluminum EN AW 6063 T5 are rot-proof, insensitive to humidity and undeformable,even in salty or humid environments.

They do not split, do not swell and require no maintenance.

Result: a stable, rigid and durable structure over time.

The profile 40×60mm, matt black RAL 9005 finish, suitable for the majority of residential terraces with a span of up to 1m.

Larger sections allow you to reach 2 to 3 m depending on the project.

2. Versatility of use

A single structure for all your coverings:

  • Wood or composite blades,
  • Porcelain stoneware or reconstituted stone slabs.

The system STRUCTURAL® simplifies logistics and ensures perfect compatibility between all the components of the terrace.

3. Fast and precise installation

The joists are easily installed on adjustable studs or foundation screw.

STRUCTURAL® connectors and brackets guarantee rapid assembly, perfectly aligned and removable if necessary.

4. High-end rendering

The finish matte black gives a neat and professional appearance, while ensuring a perfectly straight and ventilated base.

The terrace remains stable and elegant over the years.

When to choose a wooden joist?

Only for simple projects with a low budget and limited lifespan.

Wood requires more maintenance, more ventilation and offers less longevity than aluminum.
