Galvanized steel wire possesses rust-proof properties, with its principle lying in the formation of an alloy passivation layer on the surface of the steel wire, which prevents direct contact with the outside world, achieving corrosion and rust prevention effects. The zinc oxide protective layer formed by the reaction between zinc and oxygen thickens over time, protecting the internal steel wire from erosion.
The rust-proof effect of galvanized steel wire is long-lasting, especially in harsh climates where it maintains good condition, with a service life of up to 20 years or more. It is widely used in fields such as lifting machinery, elevators, and railway transportation. Its corrosion resistance is more pronounced in wet, corrosive, and high-temperature environments. Compared to ordinary steel wire, galvanized steel wire is less prone to rust when stored outdoors and has a longer service life.
However, during use, it is necessary to pay attention to protecting the galvanized layer, avoiding wear and vulnerable areas, as well as prolonged contact with water, moisture, salt spray, and chemicals. When cutting, welding, or performing other operations, it is necessary to specifically protect the surface zinc layer to avoid damaging the rust-proof layer.
In summary, galvanized steel wire achieves rust prevention through the galvanized layer, possessing long-lasting and wide application prospects, but attention should be paid to protecting the galvanized layer to extend its service life.
