Steel Home Extensions

When compared to traditional methods such as brick and timber, steel construction is more durable, faster to install, and can be manufactured almost entirely on the job site. All areas of procurement may be made more cost effective.

We don’t need to employ pricey lintels, and establishing a concrete foundation isn’t always necessary. Prefabrication off-site, if possible, allows us to complete your extension much faster than other techniques. This saves a lot of money on labour.

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

Steel vs Timber Extensions

  • There are several advantages to using steel over lumber as a building material.
  • Fires in steel-framed buildings are less likely to spread to other parts of the structure.
  • Your visitors will never show up unexpectedly since steel is impervious to decay and dampness.
  • As a result, we can completely soundproof your room using our technology.
  • When we build our extensions, no trees are cut down.

Metal Frame Extensions

When it comes to home extensions, our specialty is helping customers get exactly what they want while also making sure that the project fits both their and the property’s requirements. In the end, we want to make sure that you are happy with the final product.

With the technologies we have at our disposal, we are able to completely tailor your extension to your needs. We have a wide range of insulation materials that exceed construction requirements, allowing us to achieve significantly higher U-Values than the typical building process.
