What Starrco does

Starrco Co., Inc. is a Maryland Heights, Missouri-based manufacturer of pre-engineered modular construction components, founded in 1965. The company designs and fabricates modular wall systems, framing components, ceiling grids, electrical systems, portable buildings, mezzanines, and safety railings, all produced at its single manufacturing facility at 11700 Fairgrove Industrial Blvd. Its core technology is a proprietary wire-stud framing system (SS3000 and SS3500 variants) built from 6063-T6 extruded aluminum, with integrated electrical raceways that accept the UL-listed, color-coded "Quick-Tric" modular wiring system. Starrco assembles these components into five primary application categories: in-plant modular offices, ISO-rated modular cleanrooms, preassembled booths (guard houses, ticket booths, gate houses, smoking shelters), indoor cultivation/grow rooms, and the STARRMAX tall wall system reaching 30 feet.

Starrco sells into a broad vertical base that includes manufacturing and industrial facilities (its primary segment), pharmaceutical and healthcare cleanrooms, semiconductor packaging, warehousing and logistics, commercial/institutional access control, controlled-environment agriculture, aerospace/defense, and modular data centers. Marquee named customers include Caterpillar, Tesla, Toyota, Amazon, Walgreens, Whirlpool, Lockheed Martin, and Praxair (Linde). The business model is predominantly one-time sale of physical modular building systems priced through custom quotes, with an optional professional installation services line and self-install support via CAD drawings.

The go-to-market is sales-led through both direct channels (website quote requests, phone sales at 800-325-4259 and 888-311-1437 with most quotes returned within 24 hours) and a national dealer network that handles localized sales, installation, and customer service. Pricing is fully quote-based and not publicly disclosed. Key value propositions cited by the company include installation up to 70% faster than conventional construction, lead times 50-75% faster than stick-built, and a 7-year tax depreciation window for modular offices versus 39 years for conventional buildings.
