Solar-ready warehouse roof
Solar panel supports on a warehouse roof, with the roof designed for the panel load.
Green transition · WarehouseWhy steel is green
Four reasons
It recycles
Steel can be melted down and made again without losing its properties. A building at the end of its life is raw material, not waste.
It is lighter
A lighter frame needs a smaller foundation, so less concrete and cement are used.
Dry site
Parts are prepared in the shop and bolted together on site, with far less formwork, water and rubble.
It can be rebuilt
Bolted joints come apart, so the frame can be reused in another building somewhere else.
Comparison
Concrete and steel, through a green lens
General tendencies; every project's result depends on its own calculation.
| Topic | Reinforced concrete | Steel frame |
|---|---|---|
| Building weight | Heavy | Lighter |
| Foundation and concrete | More | Less |
| Water and formwork on site | Heavy use | Little; dry assembly |
| Build time | Longer; curing time | Shorter; prepared in the shop |
| After demolition | Rubble | Recycled or reused material |
Applications
What we do for the green transition
Steel buildings for urban renewal
A lighter, earthquake-resistant steel frame that rises quickly in place of the demolished building.
Residential · ApartmentsRooftop solar supports
Solar panel supports for warehouse, workshop and factory roofs, with the roof designed for the panel load.
Solar · Warehouse · WorkshopDemountable structures
Bolted systems for temporary warehouses, site buildings and exhibition structures that can be taken down and re-erected elsewhere.
Bolted connectionsFraming for an efficient envelope
Wall girts and roof purlins to carry sandwich panels and insulated facade systems.
Facade · RoofSample application
Five-storey apartment block
An urban-renewal block on a braced steel frame with composite floors, lighter than the building it replaces.
