Frequently Asked Questions

How much does custom welding cost in Middle Tennessee?
Every piece we build is custom, so the price depends on the material, the footage, the design complexity and the finish. Simple handrails usually land in the hundreds. Ornamental staircases, estate gates and steel framed decks are quoted per design. Quotes are always free, so call (615) 630-1840 and Rich will give you a straight answer fast.
What areas do you serve?
We're based in Franklin and serve Nashville, Brentwood, Murfreesboro, Spring Hill, Nolensville, Thompson's Station, Fairview, Smyrna, Mt. Juliet, Chattanooga and Jackson, plus Florence and communities throughout Northern Alabama.
Do you offer mobile welding?
We do. Our fully equipped mobile rig brings the shop to your driveway, jobsite or business anywhere in Middle Tennessee. It's the fastest way to handle on site repairs, gate fixes and installs that can't come to us.
Are you licensed and insured?
Yes. 3D Custom Welding LLC is fully licensed and insured for residential and commercial work, and everything we install is built to code. We hold a 5.0 star rating on Google and we're an Angi Approved Pro with a Super Service Award.
Do you handle both residential and commercial projects?
Absolutely. The same hands that build estate staircases in Brentwood build storefront ironwork in downtown Franklin, along with commercial stair systems, steel floor decks and safety railings across the region.
You Dream It. We Make It.
