What We Build
Our Services
Every project is custom. Choose from hundreds of existing cutout designs — or work with us to create your own — then pick your hinges, latches, finish colors, and decor.
Security Doors
Custom iron security doors and screen doors that protect your home without sacrificing curb appeal. Built to your opening, your style, and your budget.
Fencing & Pool Enclosures
Perimeter, security, and pool fencing built to last in the desert sun. If it's part of a pool enclosure, we'll make sure it meets code.
Stairs & Railings
Custom steel staircases, spiral stairs, handrails, and balcony railings — structural strength with a clean, finished look.

Common Questions
Frequently Asked Questions
How much does an estimate cost?
Nothing — estimates and bids are always free. We can work up a quote by phone or email, at our shop, or on-site, depending on what your project needs.
Can I customize the design?
That's the whole point. Choose from hundreds of existing cutout designs, or work with us to create your own. You also pick the hinges, latches, paint colors, and decor, so the finished piece fits your home.
Will my pool gate or fence meet code?
Yes. If your gate or fence is part of a pool enclosure, we make sure it meets code — that's part of the job, not an extra.
How is the finish applied? Will it hold up in the desert?
Painting is done with an electrostatic paint or powder coating system, which bonds the finish to the steel for durability in the Tucson sun. It far outlasts a brush-or-spray paint job.
Do you install what you build?
Yes — installation services are available for all of our products, handled by our own crew.
Can you automate my gate?
Yes, ask us about gate operator and opener devices when you get your estimate. We can build new automated gates or design yours so an operator can be added later.
Where do you work?
Our shop is at 1990 N 7th Ave in Tucson, and everything is fabricated right there — nothing is outsourced. We serve Tucson and the surrounding Southern Arizona area.
