Material Consultation
We analyze your chemical or environmental exposure to recommend the correct alloy and gauge.
2
Clean Fabrication
Segregated stainless steel and aluminum work areas to prevent cross-contamination during welding.
3
Technical Welding
Precision TIG/MIG welding by craftsmen certified in specialized industrial alloys.
4
Surface Finishing
Passivation or mechanical polishing to meet specified surface roughness and aesthetic requirements.
Frequently Asked Questions
When should I use 316L stainless instead of 304?▼
316L stainless steel contains molybdenum, which provides significantly better resistance to chlorides and pitting. It is the industry standard for marine environments, chemical processing, and pharmaceutical cleanrooms where 304 might eventually corrode.
Do you offer non-magnetic ductwork for MRI suites?▼
Yes. We specialize in heavy-gauge aluminum ductwork and non-magnetic stainless steel components specifically designed for the high-intensity magnetic environments of medical imaging rooms.
Can you fabricate high-temperature exhaust systems?▼
Absolutely. We fabricate industrial exhaust systems using heat-resistant alloys and heavy-duty welded construction capable of handling flue gases and high-temp process air up to 1000°F+ depending on material choice.
Do you provide sanitary-grade ductwork for food processing?▼
Yes. We can provide stainless steel systems with full-penetration TIG welds that are ground smooth and polished to eliminate crevices where bacteria can grow, meeting USDA and FDA requirements.
