The classification of export specific Cable Trays strictly follows the international foreign trade system classification, which is different from the conventional domestic classification method. It is finely classified based on protective structure, material technology, usage function, and adaptation environment. The category boundaries are clear and highly targeted, and can accurately match the construction standards, environmental conditions, and acceptance systems of different countries around the world, meeting the differentiated material selection needs of various overseas mechanical and electrical engineering projects.

Classified by structural form, covering the four core categories of mainstream foreign trade. Including enclosed trough bridge, hollow ladder bridge, flat tray bridge, and reinforced large-span bridge. The enclosed trough type cable tray has a fully enclosed structure, which is dustproof, waterproof, and anti-interference. It is the mainstream category of wiring for weak current, intelligent, and fire protection systems overseas; Ladder style bridge with hollow and transparent structure, excellent heat dissipation efficiency, focusing on high-power power cable laying; Tray style cable trays have uniform load-bearing capacity and flexible layout, suitable for mixed arrangement of multiple types of cables; The large-span bridge frame strengthens the overall structure without the need for dense supports, making it suitable for overseas outdoor long-distance overhead laying scenarios.

Classified by anti-corrosion materials and processes, suitable for diverse global climate conditions. It is divided into four mainstream categories: hot-dip galvanized ordinary foreign trade products, hot-dip galvanized high weather resistant products, electrostatic spray anti-corrosion products, and stainless steel anti-corrosion products. Hot dip Galvanized cable tray has high cost-effectiveness and is suitable for conventional engineering in dry and mild areas; The hot-dip galvanized bridge has a thick and dense anti-corrosion layer, stronger weather resistance, and is suitable for outdoor, rainy and windy environments; Spray painted cable trays have regular colors and good insulation, suitable for public buildings with appearance and insulation requirements; Stainless Steel cable trays come in grades such as 304 and 316L, specializing in harsh scenarios such as coastal salt spray and chemical acid alkali corrosion.

Subdivide specialized foreign trade categories according to functional attributes and adapt to special engineering requirements. Including special categories such as fire-resistant and flame-retardant export bridge, waterproof sealed bridge, split type quick installation bridge, and vertical shaft dedicated bridge. The fire-resistant bridge is equipped with an international flame-retardant protective layer, which is non combustible in the event of fire, fire-resistant and heat-insulating, meeting the strict standards of overseas fire safety acceptance; Waterproof sealed bridge with dedicated sealing strips, suitable for cross-border projects with heavy rain and underground humidity; The quick installation bridge adopts a modular split structure, which is suitable for overseas manual simplified installation mode, greatly improving construction efficiency, and covering various special construction needs overseas in multiple categories.
