What Gateway Building Systems does

Gateway Building Systems, Inc. is a privately held design-build general contractor founded in 1958 and headquartered in West Fargo, North Dakota, serving the Upper Midwest (North Dakota, South Dakota, and Minnesota) from four regional offices. The company specializes in commercial, agricultural, and industrial building construction, with in-house crews for steel, concrete, and millwright work, and operates as an exclusive dealer-partner for Butler Manufacturing pre-engineered building systems (including the MR-24 standing-seam roof) and as a major Brock and AGI Westeel grain bin dealer. Its product portfolio spans grain storage systems, grain dryers and handling equipment, aeration and unloading systems, the IntelliFarms BinManager remote grain management system, seed treatment systems, post-frame construction (pole barns with laminated posts and clear spans up to 80 feet), and post-construction building maintenance services, supported by proprietary accessories such as the patent-pending Bin SumpPRO and Flex-N-Seal grain bin sealer.

Gateway generates revenue through three primary streams: project-based commercial and agricultural construction services (design-build general contracting), grain storage and handling equipment sales and installation, and recurring maintenance and inspection services (annual building inspections priced from $399 to over $1,099 by square footage, plus roof, storm damage, and energy efficiency repairs). The company employs 101-250 staff across sales, project management, drafting, field operations, finance, HR, and safety functions, and reports an 80%+ repeat customer rate across its enterprise customer base that includes ADM, CHS, Dakota Ag, Mycogen, Titan Machinery, Tharaldson, Brock, and Butler.

In late 2025, Gateway Building Systems joined Custom Agri Systems, Inc. (CAS), a family-owned Ohio company founded in 1982 and recognized as the nation's #1 Brock dealer. Under the new structure, Gateway's agricultural divisions operate under the Custom Agri Systems name while Gateway Building Systems continues its building and construction divisions under the Gateway name, positioning the company as a two-brand regional construction and agricultural infrastructure platform with expanded procurement scale.
