Galvanized Steel Exterior Spiral Stairs


Our Galvanized Exterior line is created by manufacturing the spiral staircase out of carbon steel. To prepare the stair for exterior use, we use a “hot-dipped galvanizing process”, which involves numerous steps to prepare the parts to be dipped into a vat of hot zinc. The zinc coats every inch of the staircase to form a protective barrier against the elements. This process creates a maintenance free barrier to prevent the spiral stair from rusting making it a great outdoor choice.

If you prefer to have a color other than the grayish galvanizing finish you can paint your galvanized stair any color you would like by using the proper primer and finish paint. The galvanizing process increases the life of the paint and therefore decreases the number of times you have to re-paint your spiral staircase.

If you are looking for a cost efficient exterior spiral stair with the Salter design elements, look no further than our Galvanized Exterior line.
