Our Steel Stair Kits Are The Real Deal

Construction trends over the past few decades have favoured steel more and more. Steel is a sophisticated and modern material, whereas wood has become nearly obsolete for many reasons. Steel is also an extremely flexible and versatile material, with an impressive strength to weight ratio, and lends itself to safe and durable support structures in industrial settings.

In the past, steel has suffered from negative preconceptions about how it is sourced, how it is made, and how it can be used. However, recently, great advancements have been made in steel production and technology. Thanks to this, steel has fast become the material of choice in design and construction. Builders love it because it is lightweight, flexible, strong and easy to work with. Steel is guaranteed to save you money in the long run.

Our Steel Kits In Detail

Our stair kits arrive at your door with everything you need to assemble them quickly and easily. Our steel staircase kits come complete with:

  • Steps – The tread is the horizontal part of the step that the foot is placed on. The riser is the vertical portions between each tread. Often in steel staircases, the riser of left out, giving the flight an “open stair” look. Nosing is the part of the tread that sticks out past the riser.
  • Stringer – Stringers are the structural element that supports the tread and risers. There are usually two – one on either side of the stairs.
  • Bannister (handrail) – The element of the stair for holding. Our steel staircases can have one or two handrails. In the case of larger staircases, there can be one (or multiple) handrail(s) in the middle of the flight.
  • Fully zinc galvanised steel components to protect against corrosion.
  • Detailed assembly instructions – a booklet containing instructions on how to install your staircase correctly.
