Wholesale Custom Long Span Hot DIP Galvanized Trapezoidal Ladder Type Cable Tray for Power Cables

We have CE and ISO certifications, including raw material inspection, dimensional tolerance testing, coating thickness measurement, load testing, etc. We can provide third-party laboratory reports on load testing and salt spray corrosion testing upon request to help customers quickly complete acceptance testing locally.

The core performance standard references IEC 61537 (International General Specification for Cable Tray Systems), which has clear requirements for structural strength, corrosion resistance, and materials for fire-resistant sections. Different regional standards may have supplementary requirements, such as the NEMA standard in the North American market.

Export packaging must meet international transportation requirements: The product is first treated with stretch film for moisture and rust prevention, and then secured externally with export-grade fumigated wooden crates or reinforced wooden frames to prevent collisions and deformation during transport. The packaging will clearly mark the shipping marks, specifications, weight, and other information, complying with the customs declaration requirements of the destination port.

Standard specifications can be shipped within 7 days if in stock; customized products typically require 15-30 days for delivery. Minimum order quantity (MOQ) varies depending on the product and specifications; some manufacturers accept trial orders.

We will provide detailed installation drawings and technical instructions. For complex projects, technicians can provide remote or on-site installation guidance. For OEM orders, we can also provide a complete set of customs clearance and acceptance documents, including material certificates, test reports, and certificates of origin, upon request.
