Do you fabricate stainless only, or also carbon steel?
+
Both, but in physically separate facilities. Our 40,000 sq ft stainless-dedicated room has its own tooling, consumables, grinders, clamps, and welders. There is no cross-contamination risk from carbon steel grind dust, weld spatter, or tooling transfer. Free iron verification per ASTM A380 is available on critical-service assemblies.
What stainless grades do you fabricate?
+
Austenitic (304/304L, 316/316L, 309, 321, 347), P8, stocked with 2-day lead time on standard sizes. Duplex (2205, 2507, LDX 2101), P10H, K-TIG capable with ER2209 filler. Specialty alloys (Hastelloy C-276, AL-6XN, Inconel, Alloy 31), P43 and P45 qualified with dissimilar-weld combinations to P8 (304/316).
What is the largest piece you can fabricate?
+
Maximum single-piece envelope is 12 × 12 × 12 ft, up to 80,000 lb. We have shipped 45–80 ft assemblies using stretch flatbeds. Larger or oversized loads coordinate through our shipping team ahead of design, flag it at RFQ.
What is the thickest stainless you can process?
+
Fiber laser cuts stainless up to 1.25 in (Trumpf TruLaser 5040 Fiber). Plate rolling (Roundo PS 310) handles stainless up to 9/16 in. Press brake forming is thickness-dependent by machine, up to 5/8 in on our heavy-tonnage Trumpf brakes. For heavier plate we weld-prep with bevel cuts and K-TIG in a single pass.
Do you handle pickling and passivation in-house?
+
Yes. Our 55-foot pickling and passivation booth handles entire assemblies in one pass per ASTM A380. No sectioning, no re-welding after finish. We are one of the few U.S. shops this size with true in-house spray pickling.
Are your welders certified to AWS D1.6?
+
Yes. All 60 of our welders maintain active AWS D1.6 (Stainless Steel) qualifications, along with D1.1 (Structural Steel), D1.2 (Aluminum), and ASME Section IX P-number qualifications. Continuity logs are current and ship with the drawing package, not reconstructed at final inspection.
What industries do you serve?
+
Food & beverage (3-A sanitary, ASME BPE), water & wastewater (municipal, industrial), power / energy / chemical (exhaust ductwork, reactor internals, process piping), pollution control (scrubbers, stack liners, demister housings), pulp & paper (process tanks, chutes), and architectural stainless (mirror-polished facade panels, sculptural features).
What quality documentation is included?
+
Standard package: material test reports (MTRs) traced by heat, weld maps with WPS references, welder continuity logs, dimensional inspection records, and pickling / passivation certification. Extended: PMI (positive material identification), radiographic testing, hydrostatic test reports, Leica AT960 laser tracker inspection. All delivered with the assembly, not mailed separately.
How do you handle rush or NDA projects?
+
Rush? Flag it at RFQ. We route through expedited scheduling and our 15-person second shift (7 second-shift welders). NDA work is standard. We fabricate under NDA for power, energy, defense, and aerospace programs. CAGE Code 137T8, SAM UEI registered for federal eligibility.
Where are you located and how do I ship to you?
+
Oak Harbor, Ohio. Direct truck access, flatbed, double-drop, lowboy / RGN, and dry van dock. Stretch flatbed capable 45–80 ft. We coordinate inbound freight on request. Plant visits welcome, schedule through the RFQ form.
