A Houston, Texas manufacturer of non-penetrating rooftop support systems, founded in 1992 by Art and Lynn Valentz. It designs and builds pipe, duct, cable tray and mechanical equipment supports, walkways, crossovers, stairs and platforms that sit on the roof without penetrations, using injection-molded high-density polypropylene bases with a UV additive and hot-dip galvanized steel framing, and it states it was the first to implement zero-penetration roof support systems. Its support systems are offered for seismic and high-wind applications.
