The Iron Shop has been designing, fabricating, and finishing spiral staircases from a single facility in Broomall, Pennsylvania since 1931. Four generations of the Cohen family have run this operation – and every step of the process, from design and engineering to machining, welding, finishing, and shipping, still happens under one roof.

My family has used The Iron Shop on two occasions. One project was a 22 foot outdoor spiral staircase. They helped set up delivery company and a Crane lowered the entire 22 foot staircase into my 3rd floor floor balcony. The powder coating has held up immensely. We have enjoyed using the outdoor stairs post 4 Florida hurricanes with little or no damage. Great manufacturing and engineering to the aforementioned .Furthermore, our newest project for our Florida Bay House has us using their power coated prime interior spiral staircase kit for easy access and install. The Iron Shop sent me out easy video install to help make our experience 5 Stars. Steve and the Iron Shop staff gives you a turn key white glove experience. Many thanks and much love ❤️ for all at The Iron Shop. Daniel Simpson, Saint Augustine Florida.

Purchased a 7” diameter aluminum multiline outdoor spiral staircase which was assembled by The Iron Shop. It is larger than most of the pre-fab alternatives but worth it. It isn’t inexpensive but the quality is first rate and a distinctive addition to our home. I picked up the staircase at The Iron Shop manufacturing facility. Although the staircase only weighed about 400 lbs, its size and the chance of damaging it during a 400 mile trip to south-central Virginia made loading somewhat challenging. The manufacturing team that constructed it customized a stand that was bolted on the trailer. The entire team, and several other shop workers, pitched in to ensure safe transport; it wasn’t a cookie-cutter solution! Their pride in their work and ensuring customer satisfaction was clearly evident! The transit took about 9 hours with speeds seldom greater than 45 mph. Travelers were definitely interested in my cargo, appreciated my journey and repeatedly gave me 2-thumbs up after they figured out what they saw. Installation took about 2 days and most certainly meets our most optimistic expectations.

Common Questions

OUTDOOR STAIRCASE FAQ

Have more questions?
Call a spiral stair expert at 1-800-523-7427.

Mon–Fri 8am–8pm | Sat 8am–12pm EST.

Do outdoor staircases need to be painted?

Steel outdoor staircases should be painted to inhibit rust and protect your investment. We recommend an oil-based enamel with rust-inhibiting additive, applied after assembly. Aluminum stairs require no paint – mill finish is standard, though powder coat is available in a range of colors if you prefer a finished look.

Can I install the staircase myself?

Yes! Most outdoor spiral staircase kits from The Iron Shop can be assembled by two people with basic hand tools – no contractor required for the installation itself. We do recommend consulting a qualified contractor for cutting and framing the floor opening. Metal kits typically take one full day to assemble.

What's the best material for a coastal or waterfront environment?

For ocean, lake, or any waterfront setting, we recommend an all-aluminum staircase. Aluminum is naturally rust-free and requires no painting, making it the most durable long-term option in high-moisture and salt-air environments.

Do you offer code-compliant outdoor designs?

Yes. The Iron Shop offers Code and Non-Code stair configurations. Code stairs meet IBC/IRC requirements with in-between spindles (less than 4″ spacing between verticals) and compliant tread dimensions. Our design consultants can help you determine which configuration is required for your project and municipality.
