Stairways, Walkways, and Catwalks

The grated design and construction of our stairways, walkways, and catwalks stand up to the harshest operating environments. Our easy manufacturing and bolted design provide a cost-effective solution with the stability to meet API compliance standards in various lengths and heights.

Grated Walkways/Catwalks

Grating prevents the accumulation of snow, rain, and moisture on the walking surface of walkways and catwalks. We use a galvanized coating to provide corrosion protection and implement serrated surfaces to facilitate better traction.

​​Grated Stairways

Our grated stairways follow the same construction and design principles as our walkways and catwalks. Step treads provide a solid grip under wet conditions and accommodate a variety of durability and safety concerns in a variety of applications, including indoor, outdoor, commercial, residential, and other installations.
