Spiral Stair with Steel Bar Grating Treads

Stair Treads and Risers

Our custom stair treads and platforms are made from 3/16 inch steel plate – at 4.763mm, these are 2.106 thicker than competitors’ stairs. Platforms are fabricated to match the tread design. The proper selection of radius, riser height, tread degree, and material are necessary to achieve well designed spiral and circular stairs. Below is a sampling of our wide range of stair tread designs, and platform and riser options.
