PV Solar Mounting C Steel Purlin – Pre-Punched Solar Grade
Product Overview
Solar-specific hot-dip galvanized C channel purlin is the standard horizontal rail component for fixed-tilt photovoltaic mounting systems. Manufactured with precise pre-punched hole patterns and high straightness control, it delivers fast panel installation, consistent array alignment and long outdoor corrosion performance. This solar-optimized grade is designed for both ground-mount and rooftop PV projects, providing reliable structural support and matching the service life of modern photovoltaic systems.
Why Choose CNB Solar C Purlins?
Our solar mounting purlins are manufactured on dedicated precision roll forming lines with in-line punching and straightness control. Every section undergoes strict dimensional and coating inspection to ensure compatibility with standard solar mounting hardware. We offer both standard and high strength base grades with various coating weights to match specific project corrosion and load requirements, with large production capacity for utility-scale solar farms.
