What Interstate Gratings does

Interstate Gratings, LLC is a privately held U.S. manufacturer of metal bar gratings founded in 2007 and headquartered in Lindon, Utah, with 101–250 employees and an annual manufacturing capacity stated at 300 tons per week. The company fabricates carbon steel, aluminum (6063/6061), and stainless steel (304/304L/316/316L) gratings using four primary production methods — forge welding, hydraulic press-locking (dovetail), swage-locking, and riveting — and also distributes pultruded and molded fiberglass gratings. Its product set spans welded gratings (Types W, WS), heavy-duty welded grating (AASHTO H-15 through H-25), pressure-locked gratings (Types DT, DTS, ADT), swage-locked gratings (Types SL, SLS, SG, SGI, SGF), riveted grating, safety gratings (Deck Span, Open Grip, Tread Grip), architectural louvers, stair treads, and embed angles. The company further differentiates via proprietary branded finishes — IG GRITWELD™ (thermal-spray anti-skid), IG EcoCoat™ (gloss black paint), IG ECOCLEAN™ (stainless passivation), and IGtru™ (ADA-compliant close-mesh) — which sit on top of the underlying hardware as value-engineering attach services.

Interstate Gratings generates revenue primarily through one-time hardware sales of custom-fabricated gratings, augmented by professional-services revenue from custom detailing (in-house AutoCAD), value engineering, and specialty finish application; pricing is quote-based on material, geometry, and finish rather than published. Distribution runs through direct enterprise field sales (toll-free 888-499-8494, [email protected]) and a three-node affiliate network — Grating Pacific in Los Alamitos, CA covering the West, and Ohio Gratings in Canton, OH covering the Midwest and East. Go-to-market is supported by content marketing (Grating 101 educational hub, downloadable catalogs, company blog) and industry event participation (NASCC: The Steel Conference).

The customer base is project-driven and spans transportation infrastructure (San Francisco International Airport ICS baggage handling system — 1,084,459 lbs delivered across 39 shipments; SF Central Subway), data centers (air plenum walkways, generator and chiller platforms), sports and entertainment venues (Reser Stadium, Seattle Convention Center, MSG Sphere), industrial/process industries (chemical, refining, offshore, pulp & paper, water/wastewater), and architectural/building construction. The company is led by President Mike Clark, operates with no disclosed external equity capital, and is structured as a single-member LLC under Utah jurisdiction.
