S350GD High Strength C Steel Section – Long-Span PV Grade
Product Overview
S350GD high strength C steel section is a premium structural profile designed for large-span and high-load solar mounting systems. Built on micro-alloyed high strength galvanized steel with optimized section geometry, it delivers superior load-bearing capacity and longer span capability compared with standard mild steel sections. This grade reduces total steel consumption and foundation requirements for utility-scale solar projects, delivering lower total installed cost while improving structural reliability.
Why Choose CNB High Strength Solar Steel?
Our high strength solar sections are sourced from certified structural steel mills with strict control over mechanical properties and zinc coating quality. Every section undergoes full dimensional and straightness inspection to ensure consistent performance in large-scale solar installations. We work closely with EPCs and developers to optimize section design for specific project conditions, maximizing cost efficiency and structural safety.
