Why Use Steel Frame?

Updated: Aug 22, 2022

So why do Evergreen Garden Rooms use light gauge steel frames for the construction of our garden rooms and what makes them so special in comparison to, for example, timber framed buildings?

This is a question we are often asked here at Evergreen Garden Rooms.

There are a number of advantages to steel frame garden rooms:

  • Very quick install time, a typical garden building frame can be assembled in around half a day.

  • Structural steel components are immune to the degrading effects of burrowing insects and mammals – which can cause a problem for wooden framework unless adequately treated. Steel encumbers any infestation of woodworm.

  • Steel will not burn in the event of a fire like a timber framed building would.

  • While timber is a strong building material, it is no match for steel. Light gauge steel, also known as cold-formed steel, is far lighter and stronger than equivalent sized timber. The added strength means there’s potential to use thinner joists in the floor and roof structure. Permitted development’s height limitations mean that ceiling height is at a premium. Smaller beams can potentially add 2 – 3 inches of headroom.

  • Simple, sturdy, and reliable – a metal frame won’t undergo the same rotting, warping, splitting, and cracking over time that a timber frame might.
