What Interstate Steel Structures does
Interstate Steel Structures is a privately held, prefabricated steel building manufacturer and dealer based in San Jacinto, California, founded in 2017. The company designs, sells, and installs custom steel structures — primarily carports, garages, RV covers, utility buildings, barns, sheds, and triple-wide units — for residential, agricultural, and small-business customers across Northern California, Southern California, and Arizona. Products are made-to-order in 12 or 14 gauge steel with 50 KSI tensile strength, and are available in regular, boxed-eave, and certified vertical roof configurations in more than 18 colors, with optional windows, roll-up doors, and walk-in doors.
The company's core technology stack centers on customizable steel construction, including eco-friendly cool roof panels intended to reflect heat in summer and retain heat in cooler climates, and certified vertical roof designs with extra bracing for snow- and wind-load compliance. A digital self-service layer is provided through the IdeaRoom 3D Configurator, which lets customers design and visualize structures online prior to purchase. Manufacturing positioning is "Made in USA."
Commercially, Interstate Steel Structures sells through two primary channels: a dealer network (which it actively recruits with no royalty or franchise fees) and direct-to-consumer phone-based sales supported by a bilingual English/Spanish team at 888-654-2435. Pricing is fully quote-based and not publicly disclosed; delivery lead times run 2-4+ weeks in California and 6-12+ weeks in Arizona. The company identifies individual homeowners as its primary customer segment, with secondary demand from farmers/agricultural operators, small businesses, and buyers in jurisdictions requiring engineered/certified structures. There is no disclosed revenue, funding, M&A activity, or parent company; ownership appears to be founder/management-held.
