99.995% Zinc Spray Wire for Thermal Spray
99.995% zinc spray wire is supplied in spools for thermal spray, arc spray, flame spray and metallizing anti-corrosion coating. It is mainly applied on steel structures, bridges, storage tanks, pipelines, marine components and industrial equipment that need long-term zinc coating protection.
For spraying projects, zinc purity is only one part of the purchase check. You also need to confirm wire diameter, diameter tolerance, spool weight, surface condition, winding evenness, batch documents and export packing. These details affect wire feeding stability, coating uniformity, spool replacement frequency and incoming inspection.
We supply 99.995% pure zinc spray wire with smooth surface, stable spooling and clear batch traceability. Regular diameters include 1.2mm, 1.6mm and 2.0mm. Customized sizes and spool weights can be confirmed according to your spray gun, wire feeding system, project standard and order quantity.

Why Spool Packaging Matters
The value of spool packaging lies in stable wire feeding. During continuous operation of thermal spray equipment, winding tension, winding evenness, and spool weight consistency directly affect spool change frequency, wire feeding smoothness, and on-site operating efficiency.
We can supply 15 kg, 20 kg, or customized zinc wire spools. Each spool or outer carton can be marked with the product name, purity, diameter, net weight, and batch number for warehouse sorting, batch traceability, and incoming inspection. Export packing usually uses cartons and pallets. Packing photos can be provided before container loading.

Applications of 99.995% Zinc Spray Wire
99.995% zinc spray wire is mainly used to prepare anti-corrosion zinc coatings on metal surfaces. It is suitable for steel components exposed to humid, salt spray, industrial atmospheric or outdoor environments for a long time.
Common applications include:
| Application | Use Direction |
|---|---|
| Bridge Coating | Zinc anti-corrosion coating for exposed steel structures |
| Storage Tank Coating | Surface protection for industrial tanks and containers |
| Pipeline Coating | Anti-corrosion protection for pipeline surfaces |
| Marine Structure Protection | Zinc coating for salt spray and humid environments |
| Steel Structure Coating | Thermal spray zinc layer for industrial structures |
| Metallizing Repair | Surface repair and protective coating for equipment parts |
For bridge, marine and pipeline projects, we recommend checking COA, batch consistency, impurity control and third-party inspection. For regular steel structure coating, we recommend confirming diameter, spool weight, packing method and delivery time first.
