We produce a range of external straight staircase designs which are available in a number of different materials and finishes.
Most of our straight staircases are designed to meet a fairly 'high end' brief, as opposed to typical fire escape designs, however, the external application would tend to dictate Non-slip Steel treads and hot dipped galvanised, with the additional option of a powder coated finish.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Spiral Construction is consulted before specifying.
