Stainless Steel Fabricators Who Build What Others Can't

Complex stainless fabrication — plate to passivation, under one roof, in a shop built for stainless alone.

Stainless-dedicated
fabrication facility
Separated from carbon steel — dedicated tooling, consumables, and welders. No cross-contamination, no free iron on finished surfaces.
55-foot
pickling & passivation booth
Entire assemblies pickled in one pass. No sectioning, no re-welding after finish.
100-foot
longest stainless trough
Critical wastewater replacement delivered inside a scheduled plant outage.
60+
AWS-certified welders
Qualified to AWS D1.6, D1.1, and ASME Section IX — continuity logs available.

What others can't

Three projects other shops passed on — or tried and couldn't deliver.

Duplex 2205 Stainless Steel

When the original spec was unbuildable

Power generation facility needed large-diameter stainless exhaust ductwork to mate to existing in-plant flanges during a 5-day scheduled outage — with zero tolerance for forced alignment on site.

A fabrication room that doesn't see carbon steel

Carbon and stainless share the same shop in almost every fabrication facility. Free iron transfers from grinders, clamps, tables, and weld spatter — and shows up weeks later as rust bloom or pitting on finished stainless surfaces. Our stainless-dedicated room has its own tooling, its own welders, its own consumables. Free iron verification per ASTM A380 on critical service assemblies.

Plate to passivation, no subcontracting

Most shops outsource pickling, passivation, NDE, or post-weld finishing. That means your part travels, waits in queues, and picks up handling damage between stations. We do it all in-house: flat laser, tube laser, 5-axis laser, robotic and manual welding, a 55-foot pickling booth, PMI, radiographic testing, hydrostatic testing, and 3D scanning inspection. One partner. One schedule. One accountable name.

Welders who stay qualified on the code your project lives under

AWS D1.6 stainless qualifications aren't optional for critical stainless work — and they aren't static. Our 60+ welders maintain active qualifications on D1.6, D1.1, and ASME Section IX, recertified on a continuous cadence. When your drawing calls out a specific WPS, procedure qualification records and welder continuity logs are available on request.

Industries we serve

Where stainless steel has to perform under real service conditions.

Stainless cylinder for food-grade processing

Food & Beverage

3-A sanitary design and ASME BPE-compliant fabrication. Mixer housings, sanitary tanks, skid-mounted CIP systems, 316L weld finishes that pass crevice inspection.

Stainless equipment for wastewater treatment

Water & Wastewater

Municipal and industrial treatment systems. Troughs, weirs, chemical dosing skids, duplex 2205 storage tanks rated for chloride service and seismic loading.

Stainless components for power generation infrastructure

Power, Energy & Chemical

ASME Section VIII pressure vessels, exhaust ductwork, reactor internals. 304, 316, and high-nickel alloys for high-heat and aggressive chemical service.

Stainless emissions control equipment in fabrication

Pollution Control

Wet scrubbers, quench vessels, stack liners, demister housings. Corrosion-resistant fabrication built for sustained acid dew-point exposure.

Architectural stainless fabrication

Architectural

Mirror-polished facade panels, sculptural features, outdoor installations. Surface-quality and weld finish specified and held to the architect's drawings.

Stainless fabrication for pulp and paper mills

Pulp & Paper

Process tanks, chutes, vacuum box frames, heavy-gauge stainless equipment built to survive abrasive, corrosive mill conditions without line-stop repairs.
