Ecology
Building better with less.
Recyclable steel, dry site, reduced waste: light gauge steel framing is a concrete answer to environmental requirements.
Our approach
Environmental performance is built upstream.
Steel is the most recycled material in the world: it can be remelted endlessly without losing its properties, and our production offcuts go back into the recycling stream.
Manufacturing to the exact dimension eliminates site cutting: less waste, fewer skips, fewer return trips.
We offer European steel supply chain low-carbon steel low-carbon steels for projects targeting a reduced footprint from the structure up.

Less material wasted, less mass transported, a recoverable structure.
Actual performance always depends on the complete building, its insulation, use, service life and material sourcing. Here is the specific contribution of the LGS structure.
- Material use optimised through engineering
- Section dimensions and thicknesses are matched to the actual design forces. This optimisation aims to deliver structural performance using the necessary amount of material, without adding unnecessary weight.
- Controlled production waste
- Lengths, holes and cut-outs are defined digitally before delivery. Metal offcuts are collected at the factory, sorted and sent for material recovery.
- Lighter transport loads
- The strength-to-weight ratio of cold-formed steel enables the transport of low-mass structures. Packaging and loading sequences are planned to minimise unnecessary handling.
- Lower-footprint steel option
- Available on request, the XCarb® recycled and renewably produced range helps reduce the material footprint. Its performance is documented in a verified environmental product declaration.
- Structural longevity
- Steel does not rot or crack and is not susceptible to insect attack. The Magnelis® coating protects sections against corrosion when they are specified and installed in accordance with their exposure class.
- Demountable connections
- Components are primarily joined using mechanical fasteners. Designing for disassembly can make it easier to modify the building, separate components and reuse them where their condition permits.
- Recyclable steel
- At the end of its service life, steel retains its material value and benefits from established collection networks. It can return to steel production rather than becoming waste for final disposal.
- Potentially smaller foundations
- A lighter superstructure transfers lower loads. Depending on the geotechnical assessment and the chosen construction system, this can reduce the material volumes required for foundations and their associated impact.

Acier léger et bois : un bilan carbone comparable.
Une étude publiée dans Building and Environment (Morris, Allen & Hawkins, 2021) compare une structure en bois lamellé-collé et une structure en acier. Lorsque le recyclage en fin de vie est modélisé selon les normes actuelles, le bois se situe dans la même fourchette que l’acier : aucun classement net ne se dégage.
Le résultat dépend fortement de la méthode retenue : traitement de la fin de vie, prise en compte du carbone biogénique et de l’échelle de temps. L’acier léger est donc bien placé face au bois, sans qu’un matériau puisse être déclaré supérieur.
Nos atouts, en complément
- L’acier est recyclable à l’infini, sans perte de qualité.
- Il ne pourrit pas et ne subit ni insectes ni variations d’humidité.
- La structure est légère, donc les fondations sont réduites.
- La précision d’usine limite les chutes de matière.
- Avec l’acier XCarb® bas carbone, l’empreinte de la structure baisse encore.
