This innovative cable tray is manufactured from high-strength steel sheet through a unique cold-forming and pressing process that creates a distinctive wavy or corrugated sidewall and bottom structure. The entire assembly is then protected by a robust hot-dip galvanized coating. This design significantly enhances structural rigidity and load-bearing capacity while reducing material usage. Combined with excellent ventilation from its sidewall openings, it provides an economical, durable, and energy-efficient solution for large-span cable support in industrial plants, utility tunnels, and other applications where reducing material and installation costs without compromising performance is a key priority.
