Zinc Metallizing Wire 3.17mm 99.9% Pure Zinc for Marine and Offshore Thermal Spray Coating

Product Description

Introduction
Zinc Metallizing Wire, a type of thermal spray pure zinc wire, is specially designed for high-performance anti-corrosion applications in marine and offshore industries. Sometimes called marine-grade zinc spray wire or offshore zinc thermal wire, it is recognized for forming robust, cathodic protective coatings that perform in harsh saline environments. This wire is 99.9% pure and offers superior bonding, making it ideal for coating ship hulls, offshore platforms, and coastal infrastructure.

Material Features

• Material: Refined electrolytic zinc (Zn ≥ 99.9%)

• Surface Appearance: Clean, bright, no oil or cracks

• Form: Spool or coil

• Standard Sizes: 2.0mm, 2.3mm, 3.17mm (customizable)

• Coating Lifespan: Over 20 years with proper application

• Compatibility: Arc spray, flame spray systems

Marine Use Advantages

1. Saltwater Resistance – Excellent cathodic protection against sea water.

2. UV and Humidity Protection – Prevents premature degradation in open-air exposure.

3. Surface Grip – Strong bond to steel hulls and concrete pilings.

Use Cases

• Shipbuilding and repairs

• Offshore wind turbine bases

• Subsea pipelines

• Docks, piers, and harbor walls

Working Mechanism
Zinc acts as a sacrificial coating. When applied via arc or flame spray, the molten particles adhere to the substrate. Over time, the zinc corrodes preferentially, sparing the steel beneath. This cathodic protection significantly increases the service life of marine structures.

Specifications Table

• Excellent performance in marine climates

• Reduces corrosion-related downtime

• Lower maintenance cost for ships and platforms

• Eco-friendly protection without harmful coatings

• Long coating lifespan under harsh conditions
