When one of Tennessee's most historic academies needed an entrance worthy of its 1889 heritage, we built it. The school's crest was drawn in CAD, CNC cut in steel and set into a hand forged wrought iron gate, fabricated in our Franklin shop and installed on site. Every driveway gate, estate fence and storefront we build gets that same care.

We don't just weld metal. We build functional art that is safe, stylish and made to outlive us. The studio is based in Franklin, led by owner Rich Arnold, and we pair old world craftsmanship with CAD design and CNC precision on every job.
We come to you, walk the site, take measurements and talk honestly about budget and timeline.
Complex projects get engineered drawings first, so you approve exactly what we'll build before a single cut.
Precision cutting, forging and TIG and MIG welding, in our shop or at your site, with CNC accuracy where it counts.
A clean, professional install that is level, plumb and up to code. We treat your property like our own.
