Material Composition
Cable trays serve as "viaducts" for cables; their main structures are typically fabricated from metals such as galvanized steel or aluminum alloy. These materials offer high load-bearing capacity and corrosion resistance, effectively protecting cables from external damage. In terms of raw material composition, over 90% of cable trays fall into the category of metal products.
Role as Electrical Engineering Ancillary Equipment
Despite being made of metal, cable trays primarily serve the function of cable routing in industrial settings. They form part of the supporting infrastructure for power systems-alongside components like insulators and distribution boxes-and are generally classified as electrical auxiliary materials during procurement. This functional role often places them within the electrical supplies category in B2B procurement catalogs.
Dual Nature in Industry Perception
Manufacturing Perspective: Classified as metal fabricated products based on raw materials.
Application Perspective: Categorized as part of the electrical support system based on function.
Procurement Logic: For large-scale projects, they often appear in both the metal materials and electrical equipment procurement modules.
