Technical | Methods of Coating | Mechanical Zinc Plating
| Process | A cold process of tumbling components in a zinc dust where some adheres to the parts leaving a coating. |
| Stengths | Good for small parts, coating conforms to surfaces of substrate. Threaded parts work reasonably well. |
| Weaknesses | No metallurgical bond, zinc is mechanically adhered, and can flake off. Zinc is not continuous in nature. Only suitable for small (under 100mm) parts. Rarely available. |
| Durability | Dependent of thickness, but can give 5-10 years for small components. |
| Cost | Rarely available, so more expensive, in region of £1000/tonne or £500 per sqm |
| Health and Safety | Factory controlled (but a dirty process) |
| Environmental | Factory controlled (but a dirty process) |
