What Ray-bar Engineering Corporation does

Ray-Bar Engineering Corporation is a privately held U.S. specialty manufacturer founded in 1943 and headquartered in Azusa, California, that designs, fabricates, and supplies radiation shielding, fire-rated glass, and ballistic-resistant building products. The company serves a B2B customer base spanning hospitals and medical imaging centers, industrial non-destructive testing facilities, government and defense installations, financial and high-security buildings, architects and specifiers, and a network of authorized building material, door, glass, and medical equipment distributors. The firm explicitly does not sell to the general public or residential customers.

The company's core technology is built around lead-based radiation shielding — including lead-lined wood and hollow metal doors, lead-backed gypsum drywall and plywood, lead glass, telescopic window frames, lead sheet/plate/brick, lead vinyl, and neutron shielding materials — engineered to meet or exceed ASTM, ANSI, UL, NFPA, IBC, NCRP, and ITAR specifications. It extends this base into adjacent product categories: UL 752 Level 3 and Level 8 bullet-resistant glass, panels, and metal doors; FireLite, WireLite, and Pyrostop fire-rated glazing; and a proprietary antimicrobial product line using a permanent silver-ion exchange coating and Easy-Clean X-Ray Glass treatment tested to ASTM 2180 and JIS Z 2801 standards, with documented 99%+ reductions against MRSA, E. coli, Klebsiella, and other pathogens. Historical milestones include shielding the first U.S. Proton Beam Room and the cyclotron that produces the F-18 511keV isotope used in PET scanning.

Ray-Bar generates revenue through custom quote-based, project-driven hardware sales priced per shielding thickness, lead equivalency, ballistic level, fire rating, and antimicrobial specification, supplemented by design and specification assistance to architects and engineers. The company runs a sales-led enterprise field motion (phone, email, dedicated RFQ forms per product line), an authorized distributor/wholesale channel covering domestic and international markets, and lead-generation specialty websites (FireproofGlass.com, XrayProtection.com). It claims to maintain "perhaps the largest inventory of shielding materials in the U.S.," supports worldwide shipping, and operates with 51-100 employees across manufacturing, engineering, QA, sales, and distribution.
