About Zn-Al 85/15 Spray Wire 3.2 mm
Zn-Al 85/15 is a widely specified pseudo-alloy for thermal spray anti-corrosion coatings. The 85/15 ratio provides active cathodic protection similar to pure zinc, while the aluminum content improves coating hardness, temperature resistance, and long-term durability in atmospheric and immersion service. When sprayed at 3.2 mm diameter, the wire feeds consistently through standard arc spray equipment, producing a dense, well-bonded coating with minimal overspray.
Typical coating thicknesses range from 100 to 300 microns depending on the environment and service life target. The as-sprayed surface is slightly rough, which makes it an excellent base for paint or sealant topcoats in duplex coating systems.
Coating performance and application
Zn-Al 85/15 coatings are commonly specified for:
- Structural steel in C3, C4, and C5 corrosion categories (ISO 12944)
- Offshore platforms, ship decks, and ballast tanks
- Bridge girders, lamp posts, and guardrails
- Wind turbine towers and solar mounting structures
- Industrial ducting, tanks, and pipe exteriors
The wire is supplied on precision-wound spools or in coil packs to suit different feed systems. Standard spool sizes are 15 kg, 20 kg, and 25 kg. Coil packs are available for high-volume production setups. Exact pack selection is confirmed at the quotation stage based on your spray equipment and consumption rate.
