Hot dip galvanized cable tray is a specialized cable support and protection product for industrial outdoor engineering and corrosive working conditions. With a solid hot-dip galvanizing anti-corrosion process, it is suitable for various complex construction environments such as high tide and humidity, high salt spray, and mild acid-base corrosion. It is widely used in domestic and foreign engineering projects such as port terminals, coastal infrastructure, chemical parks, sewage treatment, outdoor power stations, etc. The product uses high-quality carbon steel as the substrate and undergoes high-temperature melting and zinc dipping process, allowing the zinc layer to deeply penetrate the surface of the steel, forming a double-layer protective structure of zinc iron alloy protective layer and outer pure zinc layer. The coating is tightly bonded, has excellent adhesion, and is not easy to peel off or peel off. Compared to ordinary spray painted bridge frames and electroplated galvanized bridge frames, hot-dip galvanizing technology has a stronger anti-corrosion penetration depth, and overall weather resistance, rust prevention, and corrosion resistance are more stable. It can resist outdoor wind and rain erosion, salt spray erosion, and industrial waste gas impact for a long time. The overall structure of the product has sufficient rigidity and balanced load-bearing performance. It can stably lay various types of power cables, communication cables, and control cables. Long term outdoor use is not prone to problems such as corrosion, damage, and structural deformation. It is suitable for various outdoor long-term service wiring projects and effectively extends the service life of cables and supporting facilities.
