Characterictics
Galvanized ERW (Electric Resistance Welded) steel square pipes are widely used in solar racking systems due to their superior strength, corrosion resistance, and cost-effectiveness. These pipes provide a stable and durable framework for mounting solar panels, ensuring long-term performance even in harsh environmental conditions.
 
Characteristics of Galvanized ERW Steel Square Pipes
High Strength & Durability – Manufactured using high-quality steel, these pipes can withstand heavy loads and extreme weather conditions.
Corrosion Resistance – The galvanized coating prevents rust and extends the lifespan of the pipes, making them ideal for outdoor applications.
Precision Engineering – ERW technology ensures uniform thickness, smooth surfaces, and tight dimensional tolerances.
Easy Installation – Square shape allows for secure bolting, welding, and assembly in solar racking structures.
Customizable Length & Thickness – Available in different sizes and thicknesses to meet specific project requirements.
