The advantages of hot-dip galvanized cable trays
Hot-dip galvanized cable tray are common types of cable channels, which are made of cold steel plates with hot-dip galvanized surface process, and are composed of straight sections of slotted, tray or ladder type cable tray,trough cable tray,perforated cable tray, etc.
Advantages of hot-dip galvanized cable containment: good anti-corrosion properties, long service life, high industrialization of production and stable quality. Therefore, it is used in a large number of outdoor environments that are subject to serious atmospheric corrosion and are not easily maintained.
1. With a thick pure zinc layer covering the steel surface, it can avoid contact between the steel substrate and any corrosive solution and protect the steel substrate from corrosion. In general weather, the zinc layer forms a very thin and dense zinc oxide surface, which is difficult to dissolve in water, so it has a certain protective effect on the steel substrate.
2. With an iron-zinc alloy layer, it can show good corrosion resistance in marine salt spray atmosphere and industrial atmosphere.
3. Strong bonding, zinc and iron are mutually soluble and have strong wear resistance.
4. Zinc has good ductility, because its alloy layer is firmly attached to the steel base, so the hot-dip galvanized parts can be cold-punched, rolled, drawn, bent and other kinds of molding, without damaging the coating.
5. After hot-dip galvanizing of steel parts, it is equivalent to one annealing treatment, which can effectively improve the mechanical properties of the steel base, eliminate the stress when forming and welding steel parts, and facilitate the turning force processing of steel parts.
