The roll-formed PV mounting rail system is a high-strength, weight-optimized structural framework designed for securing photovoltaic modules in residential rooftop, commercial flat-roof, and utility-scale ground-mounted solar installations. Manufactured by advanced cold roll-forming technology from continuous galvanized steel or aluminum alloy coils, the system includes C/U/Z-shaped rails, purlins, module carriers, and connecting brackets with in-line punched holes and embossing.
