STEEL STRUCTURE STAIRS
Glass is becoming increasing popular on staircases to help open up a hallway and allow the passage of light. Many joinery firms now offer glass on their standard staircases but there are also several solutions for those not looking for a carpeted stair and perhaps like the sleek appearance of steel.
Steel is obviously much stronger than timber, so stringers can be 8-12mm thick instead of 30-40mm on a timber stair. They also enable the glass to be bolted directly to them to form a frameless glass balustrade design.
These flights will have timber or even glass treads and costs will of course vary from supplier to supplier and will depend on the shape and height of the flight. The costs below should give you a budget to work with. We have also listed the approximate cost to have a spine support underneath the treads. A spine staircase doesn’t require stringers either side but steel beam running under the treads offering support. This results in the treads hanging either side of the spine, creating a nice cantilevered effect. However, check how bulky the beam is before you buy as some designs on the market actually block more light than a slim-line steel stringer option.
