Mechanical galvanizing is a specialized metal coating method that protects small parts, bolts, and hardware from corrosion without the use of electricity or high temperatures. Mechanical galvanizing, unlike traditional hot-dip galvanizing or electroplating, uses cold welding to adhere zinc or other metallic coatings to steel components' surfaces. This approach is especially useful for high-strength materials, threaded fasteners, and precise parts that require durability without the risk of hydrogen embrittlement.

The process starts with a thorough cleaning to remove oils, rust, and surface pollutants. The components are then placed in a revolving drum alongside zinc powder, glass bead medium, and a proprietary chemical promoter. As the drum turns, the mechanical force causes the zinc particles to adhere uniformly to the metal surface via cold fusion. The end product is a smooth, dense coating that adheres closely to the substrate, offering long-term protection against rust and weather exposure.

One of the primary advantages of mechanical galvanizing is its ability to coat complex geometries, such as threaded and recessed sections, without causing excessive accumulation or dimensional changes. This makes it excellent for bolts, nuts, screws, washers, and other important fasteners found in construction, automotive, and industrial settings. Furthermore, because the process does not involve high temperatures or electrical currents, it removes the possibility of hydrogen embrittlement, which is a typical worry with electroplating, making it an ideal choice for high-strength steel components.

Another benefit of mechanical galvanizing is its environmental friendliness. The technique does not use harmful chemicals like cyanides or chromates, which reduces waste and environmental damage. It also uses less energy than hot-dip galvanizing, making it a more affordable and environmentally friendly coating alternative. Zinc coatings applied via mechanical galvanizing provide good sacrificial protection, which means that the zinc layer corrodes before the base metal, considerably prolonging the service life of coated objects.

Mechanical galvanizing is frequently utilized in industries that require high corrosion resistance and part integrity. Applications include electrical transmission hardware, agricultural equipment, maritime components, and military-grade fasteners. The coating thickness can be accurately adjusted to suit industrial requirements, such as ASTM B695 for mechanical zinc coatings, assuring consistency in quality and performance.
