Metal garage: an economical and durable sheet metal garage
Metal garage: durable and cost-effective
Whether it’s to protect your vehicle from the elements, create a DIY workshop or free up space in your home, adding an outdoor extension is often essential for improving the comfort of your home. In this market, the metal garage is now the obvious choice for a great many households. Long seen as a simple, temporary and unattractive structure, it has evolved considerably both technically and visually.
Today, they offer modern architectural designs, exceptional modularity and rock-solid resistance to the elements. Easy to install, very economical to buy and requiring very little maintenance, they represent an excellent alternative to traditional brick-and-mortar construction.
Let’s take a closer look at the many benefits of this innovative structure and all the practical advice you need to successfully complete your extension project.
Why choose steel: comparison and durability
When comparing timber construction with steel-framed construction, the advantages quickly tip in favour of metal. Timber, whilst aesthetically pleasing, requires regular and thorough maintenance (application of wood stain, fungicide treatments).
The advantages ofgalvanised steel for outdoor storage are undeniable. Thanks to hot-dip galvanisation, the structure becomes extremely resistant to corrosion and oxidation. It is unaffected by prolonged damp or insect pests such as termites. The lifespan of a powder-coated steel structure can therefore easily exceed several decades, guaranteeing an excellent return on investment in the long term, whilst remaining a 100 per cent recyclable material at the end of its life cycle.

Choosing the right model and finishes
A 20 m² metal garage often strikes the perfect balance in terms of space requirements. This generous internal area is more than sufficient to comfortably park a family saloon or a large SUV, whilst leaving plenty of space on either side to open the doors without the risk of bumping them.
When it comes to the walls and the outer cladding, the choice is crucial: opt for single-skin cladding or insulated sandwich panels.
- Single-skin cladding: this is the most economical and lightweight basic solution, perfectly suited if you’re simply looking to protect a car effectively from the elements and bird droppings.
