The spec, the fabrication approach, and the measured result. Documented builds in 304L, 316L, and duplex stainless from Oak Harbor, Ohio.
Each case study covers the requirement, how Northern built it, and the outcome the customer measured.
Regional wastewater authority needed a 100-foot 304L stainless trough to replace a failed unit during a planned outage. Straightness was specified within 1/8 inch over the full 100-foot length. The previous fabricator couldn't hold tolerance over the span.
Food & beverage OEM was seeing stainless weld joints fail in the field within months. Previous fabricator had not adjusted joint geometry for the service environment.
Power generation facility needed large-diameter stainless exhaust ductwork to mate to existing in-plant flanges during a scheduled outage, with zero tolerance for forced alignment on site.
A 67-foot, 100-ton stainless steel monocoque with 72 unique multi-ton panels, sharp corners that ruled out press brake forming, and no two faces parallel. As designed, the structure was considered unbuildable.
