Steel Home Extensions

In comparison to traditional methods, including using brick and timber, steel construction is more durable, quicker to install, and can be manufactured almost entirely on your job site. Offering a more cost-effective procurement process.

There is no need for us to use pricey lintels, and it’s not necessary to establish a concrete foundation. Completing the prefabrication off-site, it helps to reduce costs and disruption on the ground.

Steelgram can provide prefabricated steel home extensions to your exact specifications.

Steel vs Timber Extensions

There are several reasons why you may wish to use steel rather than lumber as a building material. When you opt for steel, fires are less likely to spread to other parts of your structure.

You don’t have to worry about decay and dampness, and your room can be completely soundproofed with our innovative technology. No trees need to be cut down to create our steel extensions, which makes them more sustainable.

Metal Frame Extensions

We have a great deal of experience when it comes to creating the ideal home extensions for our clients’ needs.  We’re always passionate about ensuring our clients are fully satisfied with the end product.

The technologies that we have at our disposal ensure we’re able to completely tailor your extension towards your requirements. We can use insulation materials which exceed rather than just meet construction requirements. These enable us to achieve considerably higher U-values than you might receive elsewhere.

Just give us a call if you have any questions or would like a free estimate.

Why Cold-Formed Steel?

Modern and future construction requires environmentally friendly materials which can be delivered quickly. Cold-formed steel can shorten construction periods, lower costs and offers a wide range of design options. If you need a long-lasting practical solution for high-end structures, cold-formed steel could be the ideal match for your needs.
