Spin galvanizing is a process used to coat small metal parts with zinc. It is particularly useful for coating small, complex parts that may be difficult to dip into a galvanizing bath. The process involves placing the pieces in a basket, which is then submerged in molten zinc, withdrawn, and spun at high speeds. Spin galvanizing is used to increase the lifespan of steel by making it more robust, durable, and rust-resistant.
SPIN GALVANIZING
Spin galvanizing is a cost-effective, efficient and environmentally-friendly method for coating small parts with zinc.
It offers enhanced adhesion, consistency and reduced material waste compared to other steel protection methods. It is the ideal choice for protecting your small metal pieces.

What Is Spin Galvanizing?
How It Works
Step 1
The parts that need treating are cleaned and prepared for galvanizing. This involves removing any dirt, grease, or other contaminants.
Step 2
The parts are placed in a basket which is then submerged into molten zinc. The basket acts as a barrier, stopping the pieces from being lost in the bath.
Step 3
Once a zinc/alloy layer forms, the basket is withdrawn and spun in a centrifuge at high speeds. The spinning action distributes the zinc evenly over all parts and removes any excess, creating a smooth, uniform coating.
Step 4
The coated parts are removed from the basket and inspected to ensure that the coating is even and free of defects.
Benefits of Spin Galvanizing
Protect small pieces
One of the main benefits of spin galvanizing is that small parts can be galvanized without being dipped directly into a bath. You gain the benefits of hot-dip galvanizing without losing any pieces. This makes it an ideal solution for protecting fasteners, fixings, hinges, and chains.
Cost-savings
You can expect to see a greater return on investment with spin galvanizing. Spin galvanizing makes the metal more durable, reducing the frequency of maintenance needed, and reducing the associated labor costs such as transportation. It is also a fast process with a short turnaround time, so the parts are returned to you quicker.
Increased protection
Unlike surface-level coatings such as paint, the zinc layer formed by galvanizing chemically bonds to the metal, making it stronger against corrosion. The zinc coating is also thicker than alternatives, further contributing to its durability. The increased durability enhances the metals lifespan, saving you time and money on repeated coatings.
Environmentally friendly
Galvanizing produces less waste compared to other methods, as it only uses the amount of zinc needed. This makes it an environmentally-friendly option, fitting into a circular economy.
