The raw material of hot dip zinc cable tray is cold rolled steel plate, and the surface process is hot-dip galvanizing. A solid structural system consisting of slots, pallets or stepped straight sections, bends, tees, quads and supports, hangers, etc.

1、 What is the principle of hot dip zinc cable tray

Hot dip galvanizing layer is zinc attached to steel by following three processes under the liquid state with high temperature.

1. The surface of iron base is dissolved into zinc solution, and the zinc iron alloy layer appears.

2. The zinc ions in the alloy layer further spread into the gas, resulting in the mutual dissolution layer of zinc iron.

3. The surface of the alloy layer is covered with zinc.

2、 Performance characteristics of hot dip zinc cable tray

1. The steel surface is covered with a hard and tight pure zinc layer, which can prevent contact with steel gas and corrosion solution and protect the steel base from corrosion. In general environment, zinc oxide layer surface will form very thin and compact, which is difficult to dissolve in water, which has a certain protective effect on steel matrix. Zinc oxide produces other components and insoluble zinc salt in the air, which has stronger anti-corrosion function.

2. Hot dip zinc cable tray has ferrozinc alloy layer, which is closely combined, and has a unique corrosion resistance in marine brine air and industrial air.

3. Due to the strong bonding, zinc iron dissolves with each other, and has strong wear resistance.

4. Zinc has excellent ductility, so the alloy layer and steel base are strong, so hot-dip parts can be formed by cold stamping, rolling, drawing, bending, etc. without damage to electroplating.

5. After hot galvanizing of steel structure, it is like an annealing process, which can improve the mechanical properties of steel matrix reasonably, eliminate the stress during forming and welding of steel, which is helpful to the lathe processing of steel structure.
