Question 1

What is the factory price range for your Galvanized Steel Strut Channel?

Accepted Answer

The factory price varies by specifications 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.

Question 2

What material grades are available for the galvanized strut channel?

Accepted Answer

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

Question 3

What surface finishes does the product come with?

Accepted Answer

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

Question 4

What sizes of galvanized strut channels do you offer for solar mounting?

Accepted Answer

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

Question 5

What is the maximum load capacity of your galvanized strut channels?

Accepted Answer

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).

Question 6

Can the strut channels be cut or modified on-site?

Accepted Answer

Yes, our galvanized strut channels can be easily cut or modified on-site using standard tools: Cutting: Use a hacksaw, angle grinder, or metal shear to trim the channel to the desired length. Drilling: Pre-drilled holes (standard spacing: 50mm or 100mm) allow for easy bolt installation. For custom holes, use a drill bit slightly smaller than the bolt diameter to avoid cracking the zinc coating. Welding: Carbon steel channels can be welded, but stainless steel channels require specialized equipme

Question 7

What is the lead time for orders?

Accepted Answer

Lead times vary by order quantity and customization level: Standard Sizes (In-Stock): Orders for pre-made 3m-6m lengths (standard sizes) are shipped within 15-30 days after deposit payment. Custom Sizes/Quantities: For non-standard sizes (e.g., 100x100mm) or large orders (over 10 tons), lead times extend to 30-45 days due to production scheduling. We prioritize bulk orders for solar mounting projects-contact us to confirm lead times for your specific timeline.

Question 8

Do you offer OEM/ODM services for galvanized strut channels?

Accepted Answer

Yes, we specialize in OEM/ODM services for galvanized strut channels. Whether you need custom sizes, finishes, or packaging (e.g., bulk bundles, palletized), our team can accommodate your requirements. We also provide technical support to ensure the channels meet your project's design standards (e.g., load capacity, corrosion resistance).

Question 9

What is the warranty for your galvanized strut channels?

Accepted Answer

We offer a 1-5 year limited warranty against manufacturing defects (e.g., cracks, coating peeling, dimensional inaccuracies). The warranty period depends on the finish: Hot-Dip Galvanized: 3-5 years (protects against rust for outdoor use). Pre-Galvanized: 1-2 years (suitable for indoor use). Powder Coated: 2-3 years (resists scratches and fading). The warranty covers replacement or repair of defective products-contact us with proof of purchase for claims.

Question 10

How do you ensure the quality of your galvanized strut channels?

Accepted Answer

We adhere to strict quality control measures to ensure our products meet international standards: Material Inspection: Raw materials (carbon steel/stainless steel) are tested for tensile strength, yield strength, and chemical composition. Galvanizing Process: Hot-dip galvanizing is performed in accordance with ASTM A123 standards, ensuring a minimum zinc coating thickness of 85 microns (for outdoor applications). Dimensional Checks: Each batch is inspected for size accuracy (width, height, thick
