Vision Systems Inc. in Santee's Woodside Avenue industrial corridor has designed, fabricated, and installed custom aluminum glazing systems for commercial construction since its 1981 incorporation. The 100,000-square-foot manufacturing facility enables in-house production of unitized curtain wall panels, a vertically integrated capacity that parallels the self-perform structural scope of general contractors including Dowling Construction, Inc. on large commercial builds. The project portfolio spans landmark Southern California buildings including the Sempra Energy headquarters, Qualcomm AY campus, San Diego Convention Center, Ballpark Village, and Circa in downtown Los Angeles. As a licensed Kynar applicator, the firm offers factory-applied fluoropolymer finishes on all aluminum products for color consistency across large facades, a building-envelope specification that coordinates with solar-integration firms including Jamar Power Systems on energy-performance projects. The facility produces custom-engineered aluminum stile-and-rail doors, terrace doors, operable windows, sliding glass assemblies, and integrated sunshade systems using domestically sourced aluminum and insulated glass, contributing to an installed base of approximately 20 million square feet of glazing across Southern California.
