Galvanized Spiral Stairs

A Long-Term Solution for Rough Weather

Mylen uses a galvanizing method known as “hot-dipped.” This is a process where the steel stairs that we’ve already engineered and welded into a rock-solid rigidity are further reinforced by hot-dip galvanizing each individual component inside and out. All galvanizing is done in a dedicated facility located in New Jersey.

Hot-dip galvanizing is the process of dipping fabricated steel in vat filled with molten zinc. While the steel is in the vat, the iron in the steel metallurgically reacts with the molten zinc. The result is a tightly-bonded alloy coating that provides superior corrosion protection for your steel stairs. Therefore, what emerges from the hot-dip is a stair with a structure ready for the rigors of the outdoors and a rugged look to match its strength.

This rugged, or “natural,” look has a “battleship gray” appeal that most customers love and keep. However, if you want a splash of color to match the stair to your space, painting with any number of color combinations is possible so long as you apply the appropriate primer. Just wait until after the weathering period (typically 6-9 months).
