What We Build
Sanitary & Food Grade
316 sanitary tube, jacketed pipe, and food-safe fabrication for dairies, food processors, and beverage plants.
Custom Fabrication
One-off builds in stainless, carbon, and aluminum — process tables, skids, manifolds, vessels, and frames.
Platforms & Handrails
Mezzanines, access platforms, stairs, and OSHA-compliant handrail fabricated and installed.
Pipe System Installation
Full design-assist installs with expert project management, from tie-in to startup.
Nested Maintenance
A cost-effective embedded maintenance crew for plants that need skilled pipefitters on call.
The Shop
Quality fabrication starts long before installation. Our Freeport facility handles offsite fabrication at any scale — your production floor stays productive while we build, and installation day is a tie-in, not a construction project.
