A traditional zinc coating method where metal parts are dipped in molten zinc (~460°C) to form a protective barrier. The zinc layer reacts with the environment to create a durable zinc carbonate layer, shielding the base metal from corrosion. Ideal for: large structures or components requiring a proven, cost-effective corrosion solution.

Key Features:

• Widely accepted in structural and industrial applications
• Distinctive crystallised zinc finish
• Long-term rust prevention in exposed environments

ZincGuard360™ is a dual-layer corrosion protection system that combines the barrier and galvanic protection of Zinc Thermal Diffusion (ZTD) with a secondary protective layer, such as a primer or topcoat, for enhanced durability in aggressive environments.

In the first stage, a dry thermal diffusion process bonds zinc to the steel substrate, forming a dense, uniform zinc-iron alloy layer with no risk of hydrogen embrittlement. This base layer provides full 360° coverage, including threads and complex geometries.

The second stage applies a specialised primer or topcoat, creating an additional barrier against moisture, oxygen, and chlorides, significantly improving performance in salt-laden and abrasive conditions.
Key benefits include:

• Combines galvanic, barrier, and sealing protection
• Up to double the corrosion resistance of single-layer zinc coatings in salt spray testing
• Full 360° uniform coverage, including threads and recessed areas
• Strong adhesion that resists peeling, flaking, and underfilm corrosion
