The common specifications and zinc layers of high zinc galvanized wire for different application scenarios are as follows:

Common Specifications

Diameter Range: The diameter of high zinc galvanized wire usually ranges from 0.15mm to 6.0mm. Common diameters include 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm and so on.
Wire Gauge Sizes: The common wire gauge numbers include SWG (British Standard Wire Gauge), BWG (Birmingham Wire Gauge) and AWG (American Wire Gauge). For example, SWG 36 corresponds to a diameter of about 0.193mm, SWG 20 corresponds to a diameter of about 0.914mm; BWG 36 corresponds to a diameter of about 0.127mm, BWG 20 corresponds to a diameter of about 0.889mm; AWG 36 corresponds to a diameter of about 0.127mm, AWG 20 corresponds to a diameter of about 0.812mm.

Common Zinc Layers

Hot-dip Galvanizing: The maximum zinc coating amount of hot-dip galvanizing can reach about 300g/m², and the zinc layer weight of high zinc hot-dip galvanized wire is usually between 200g/m² and 500g/m², and the corresponding zinc layer thickness is approximately between 30μm and 70μm.

Application Scenarios

Power Industry
- Guy wires of power towers: Usually, high zinc galvanized wire with a zinc layer weight of 300g/m²-500g/m² is used to ensure the safety and stability of the power tower for 30 to 50 years.
- Fences and protection facilities of substations: High zinc galvanized wire with a zinc layer weight of 250g/m²-400g/m² is often used to prevent facility damage and safety hazards.
Communication Industry
- Overhead support wires of communication lines: High zinc galvanized wire with a zinc layer weight of about 300g/m² is generally used to provide reliable anti-corrosion protection for 20 to 30 years.
- Protection nets of communication base stations: High zinc galvanized wire with a zinc layer weight of 200g/m²-300g/m² is often used to meet the anti-corrosion and protection requirements.
Transportation Industry
- Highway guardrails: High zinc galvanized wire with a zinc layer weight of 300g/m²-400g/m² is usually adopted to ensure good protection performance and appearance for 15 to 20 years.
- Cables and protection nets of bridges: Generally, high zinc galvanized wire with a zinc layer weight of 400g/m²-600g/m² is used to effectively extend the service life and reduce maintenance costs.
Construction Industry
- External wall protection nets of high-rise buildings: High zinc galvanized wire with a zinc layer weight of 200g/m²-300g/m² is often used to ensure that the protection net will not rust obviously in about 10 to 15 years.
- Binding wires in coastal areas or areas with serious industrial pollution: High zinc galvanized wire with a zinc layer weight of 300g/m²-500g/m² is generally used to ensure the stability and safety of the building structure.
Agriculture Industry
- Mariculture cages in coastal areas: Usually, high zinc galvanized wire with a zinc layer weight of 400g/m²-600g/m² is used to ensure that the cage will not be corroded in 5 to 10 years.
- Support wires for agricultural irrigation water pipelines placed outdoors for a long time: High zinc galvanized wire with a zinc layer weight of 200g/m²-300g/m² is often used to prolong the service life of the support wires and ensure the normal operation of the irrigation system.
