Galvanized Spiral StairsA Rugged and Durable SolutionMetal Stairs Meant to LastA Safe and Sturdy Staircase for Any ApplicationA galvanized, metal spiral staircase offers an outdoor solution that’s long-lasting, maintenance-free, and budget-friendly. Salter’s hot-dipped, galvanization process involves coating each individual stair component with a molten zinc, creating an alloy bond that armors the stair against harsh elements like salty sea air, heavy precipitation, and more for a lifetime of hard use.The Galvanized Metal AdvantageImmediately following the galvanization process, the stair turns a shiny chrome. Following this period (where gases slowly escape the stair) the metal surface of the stairs turns a battle-ship gray that offers a rugged and worn charm perfect for shore home and other seaside settings. That rugged aesthetic translates into the frame of the metal spiral stair, which is built to last a lifetime maintenance and rust free in even the harshest of settings. This longevity comes both in terms of the finish thanks to the galvanized armor and the overall structure thanks to unmatched welding techniques along each seam and other engineering features throughout the metal spiral staircase.Metal Stairs for a Lifetime of Use on Any BudgetThis lifetime durability also comes at a lower price point than other similar maintenance-free metal staircase options, making this the most economical choice for harsher environments. You also don’t have to sacrifice aesthetics for the lower price point. Once the 6 month period is up and all the gases have escaped from the zinc in the finish, you can still paint the metal spiral stair whatever color you wish. However, most choose to keep the rugged gray look because of its nautical appeal, adding to its value in shore home settings.Commercial Grade Metal StairsThis metal spiral stair’s ruggedness and durability also makes it a smart installment for commercial sites where money is best spent elsewhere but quality still can’t be sacrificed. From large-scale commercial sites to private work and hobby shops, the galvanized metal of this stair’s frame prepares it for any work hazard and the price tag allows you to invest in equipment and other vital for keeping your shop running efficiently.Galvanized Metal Spiral Staircase Design FactorsMore than being a durable metal staircase at a budget-friendly price point, our galvanized staircase line also offers an irreplaceable aesthetic that makes it ideal for nautical settings such as shore homes with decks or docks.
