Sizes and types of hot-dip galvanized iron wire
By wire diameter
It can be divided into fine, medium, and thick wires. Wire diameters range from 0.5-1.0mm, 1.2-3.0mm, and 3.5-6.0mm. Fine wire is used for weaving handicrafts and securing small indoor items. Medium-thick wire is used for tying construction rebar, supporting grape trellises, and fencing. Thick wire is used for high-strength applications. and load-bearing capacity.
Zinc layer weight
30-120g/m² is suitable for indoor lashing, general outdoor fencing, and other applications for daily corrosion protection. Zinc layer weight ≥200g/m² can be used in highly corrosive environments such as coastal areas and chemical plants.
Tensile strength
Generally, the tensile strength of hot dipped galvanized iron wire ranges from 350-650MPa. For higher tensile strength requirements, high-strength options can achieve ≥800MPa. Through the cold clamping process, it is suitable for securing heavy machinery.
Tensile strength and zinc layer weight of hot-dip galvanized iron wire
Through this detailed introduction to hot dipped galvanized iron wire, we've learned about tensile strength and zinc layer weight. Is there a direct relationship between the two? In reality, there's no clear correlation between the two; they are determined by different factors:
Tensile strength: The wire's material, rolling process, and annealing treatment determine tensile strength. Cold drawing increases tensile strength, while annealing reduces strength and improves flexibility.
Zinc coating weight: Its function is to enhance corrosion resistance and has little to do with load-bearing capacity. The zinc coating is softer than the wire, and its tensile strength is very weak, essentially having no effect. Therefore, there's no significant correlation between the two.
The tensile strength of hot dipped galvanized iron wire is determined by the base material itself, while the zinc coating weight only affects corrosion resistance. The two play different roles.
Corrosion resistance of hot-dip galvanized iron wire
The primary performance of hot dipped galvanized iron wire lies in its corrosion resistance. So, what factors determine its corrosion resistance?
Zinc layer thickness and uniformity
If the zinc layer thickness is below the standard, the corrosion resistance period will be shortened. Rust will occur first if there are missing plating, uneven plating, or welds that have not been treated.
01
Passivation treatment
If there are residual oxidants on the surface or the passivation film is incomplete, the zinc layer is prone to oxidation and white rust, which will shorten the service life.
02
Environmental factors
The service life will also vary in high salt spray, coastal environments, acidic and alkaline media, high temperature and high humidity environments.
03
Damage factors
Whenhot dipped galvanized iron wire is used for a long time, it will be subjected to external impact or repeated bending. If the zinc layer peels off, it will also shorten the service life.
04
