All our commercial and large domestic steel spiral staircase are custom made. As each application is a little different the going, rise and platform sizes need to be formed to suit the project. For this reason full working drawings are prepared for each spiral staircase.

Treads :-

Non Slip Perforated Steel
Tear Drop / Chequer plate Steel
Steel plate to take infill
Mesh / Grating

The balustrade itself is in-filled by either :-

Vertical Steel Spindles
Horizontal steel rails
Curved mesh panels

The handrail is generally 42.4mm diameter and the platforms are generally square in shape, situated level with the finished floor. Form domestic applications a small riser bar or steel back plate can be added to comply with the 100mm gap rule.

The vast majority of these spirals staircases are supplied for external use and are therefore galvanised for protection. Internal models can be supplied primed for on-site painting or full powder coated. For those wishing to have a coloured external flight, a special powder coating finish can be added to the already galvanised surface.
