Staircases Built To Impress, And To Code

A staircase sets the tone for the whole house. It's the first thing people see in the foyer and the piece they remember on the way out. We design and build custom metal staircases all over Middle Tennessee, from floating steel stringers in modern Nashville builds to classic wrought iron in Franklin's historic homes.

Every stair starts with a conversation and a CAD drawing you approve before we cut anything. Then it's fabricated with clean TIG and MIG welds, ground smooth and finished like a piece of furniture. And because a staircase is safety equipment first, everything we build meets residential or commercial code. Your inspector will have nothing to flag.

Frequently Asked Questions

How long does a custom metal staircase take?
Most residential staircases run 3 to 6 weeks from approved CAD design to installation, depending on complexity and finish. Commercial systems get scheduled around your construction timeline, and we're known for hitting our dates.
Can you replace my existing wood staircase with metal?
Yes, and stair remodels are one of our favorite jobs. We template the existing opening, fabricate in the shop, then swap the structure with minimal demolition and dust.
Are your staircases code compliant?
Every stair we build meets IRC residential or IBC commercial requirements for rise and run, guard height, baluster spacing and load. We're licensed, insured and inspection ready.
Steel, iron or aluminum? Which should I choose?
Steel gives maximum strength and the cleanest modern lines. Wrought iron brings classic ornamental character. Aluminum is lightweight and great outdoors. We'll recommend the right metal for your design and budget at the free consultation.
