Does a square-section steel pole with hot-dip galvanized coating really outperform round tubes in torsional stiffness while supporting solar lights and cameras under 45 m/s wind loads
In distributed solar applications such as street lighting, surveillance poles, communication relay stations, and small off-grid PV systems, the mounting pole is often treated as a commodity item — yet its cross-sectional shape, coating durability, and bracket topology directly determine whether the system survives gusty winds or fails at the base weld after a few…
