RB Industries, founded in 1978 on Santee's Prospect Avenue, designs, fabricates, and installs ADA-compliant hospitality signage for hotels, resorts, and casinos nationwide. The fabrication facility at 9919 Prospect Ave houses graphic designers, CNC fabricators, and installation crews under one roof, sharing the Prospect Avenue industrial corridor with precision-machining operations at San Diego Engine Parts. Each project follows a four-phase workflow — property survey, architectural-plan review, traffic-flow analysis, and signage-hierarchy mapping — before any dimensional letters or wayfinding panels enter production. Interior and exterior sign packages incorporate routed aluminum, cast acrylic, and brushed-metal substrates with Braille and tactile elements that meet 2010 ADA Standards for Accessible Design. The same CNC routing and substrate-finishing processes scale down from 500-room resort packages to single-tenant commercial signage on Prospect Avenue, where the auto-performance corridor near The Dyno Shop shares the 92071 industrial zone. Full-service installation teams handle multi-story monument signs, illuminated channel letters, and directional kiosk systems across properties exceeding 500 guest rooms.
