Premium Galvanized Steel U Channel Mounting Rails for Solar Installations

The factory price of our Galvanized Steel Strut Channel varies by specifications (e.g., size, thickness, finish) and order quantity. For standard 41x41x2.5mm hot-dip galvanized strut channels, the price typically ranges from 0.50-1.50 per kilogram for bulk orders (1 ton or more). Smaller orders (less than 1 ton) may have slightly higher per-unit costs due to production and logistics adjustments. Contact us directly with your specific requirements for an accurate quote.

We offer two primary material grades for our galvanized strut channels: Carbon Steel: The most cost-effective option, suitable for general-purpose applications (e.g., rooftop solar mounting, indoor electrical support). It is hot-dip galvanized to resist corrosion. Stainless Steel (304/316): Recommended for harsh environments (e.g., coastal areas, chemical plants) where corrosion resistance is critical. 304 offers good resistance to rust, while 316 provides superior protection against saltwater a

Our galvanized strut channels are available in three main surface finishes to suit different environments: Hot-Dip Galvanized (HDG): The most popular choice, providing a thick zinc coating for long-term outdoor corrosion resistance (ideal for rooftops, ground-mounted solar systems). Pre-Galvanized (GI): A thinner zinc coating applied before forming, suitable for indoor or dry environments (e.g., warehouses, indoor electrical racks). Powder Coated: A colored epoxy or polyester coating for aesthet

We stock a range of standard sizes optimized for solar mounting applications: 41x41mm (C-channel): The most widely used size for solar panel racking, providing a balance of strength and weight. 41x21mm (Slim C-channel): Ideal for lightweight solar panels or space-constrained installations (e.g., carports, small rooftops). Thickness: 1.5mm-3.0mm (standard for solar mounting is 2.0mm-2.5mm to support 50-300kg/m load). Custom sizes (e.g., 50x50mm, 100x100mm) are available for large-scale projects-c

The load capacity depends on the channel's size, thickness, and span. For example: A 41x41x2.0mm hot-dip galvanized strut channel can support approximately 500-600kg/m (uniform load) over a 1-meter span. A 41x41x2.5mm channel increases this to 700-800kg/m, suitable for heavy solar panels or wind loads. Always refer to our technical datasheets or consult our team for load calculations specific to your project (e.g., span length, wind speed, snow load).
