Aluminium Cast Spiral Stairs

Aluminium Cast Spiral Stairs

RMJ Alloys of Coventry have been a long established manufacturer of cast aluminium spiral stairs over the past 25 years. As at the end of 2010 the principle of the company retired and as a consequence the company ceased trading.

Cottage Craft Spirals has purchased all the patterns for the spiral staircase treads, straight treads, balusters and landing plates which now means we can offer an enormous range of diameters, treads angles and straight treads, the largest range in the world, cast in our own foundry in Stoke on Trent.

The range of spiral staircase diameters is as follows
