Corval Group

What Corval Group does

Corval Group, Inc. is a privately held, owner-operated mechanical construction, engineering, fabrication, and service firm headquartered in St. Paul, Minnesota, with continuous operation since its 1921 founding (originally as Axel Newman Heating and Plumbing) and 501-1,000 employees. The company provides integrated single-source delivery for complex industrial and commercial facilities across six verticals: Power and Energy, Oil/Gas/Chemical, Food/Beverage/Agriculture, Public and Institutional, Manufacturing, and Commercial. Its core offering bundles project development, preconstruction, engineering, construction (EPC, design-build, construction management, or general construction), in-house fabrication, refrigeration (natural and synthetic refrigerants), and 24/7 service and maintenance, sold directly to enterprise clients under multi-year, project-based custom contracts.

The company's underlying technical platform is anchored by 60,000+ square feet of in-house fabrication capacity handling 1/2 to 60 inch pipe in carbon steel, stainless, super duplex, and exotic metals, plus long-held regulatory certifications (ASME S & U stamps and National Board R-Stamp, valid through January 2026) that qualify it for power boiler, high-pressure piping, and pressure vessel work. A documented quality management system and an industry-leading safety program (EMR 0.50 vs. national 1.0, 11 million hours no lost time) underpin execution risk control on high-hazard industrial projects. Named customers include ExxonMobil, Xcel Energy, Northwestern Energy, Enbridge, ONEOK, Tesoro (since 2013), Flint Hills Resources, Cargill, Nestlé, PURIS, DOLD Foods, Bellisio Foods (30+ year partnership), Michael Foods, Louis Dreyfus, and Hennepin County.

Corval generates revenue primarily through professional services and hardware sales tied to multi-million dollar, multi-year project engagements (EPC, design-build, general construction, construction management) plus a managed-service annuity from 24/7 emergency and embedded maintenance contracts. Pricing is quote-based and project-specific with no public pricing tiers. GTM is direct enterprise field sales — relationship-driven, leveraging 100+ years of brand history, safety reputation, and referenceable work — supplemented by a prequalified subcontractor network and joint ventures with engineering/design firms (SSOE, VAA, RSP Architects). Geographic reach is concentrated in the Midwest with active construction licensure in 15+ U.S. states and regional offices in St. Paul, Atwater (fabrication), and Bismarck.
