Why Polish Your Nails? The Nail Polishing Machine
After the nails are formed and the caps are ready, you might think the process is complete. But in my experience, adding a polishing stage significantly improves the quality and marketability of your roofing nails. This is where the Nail Polishing Machine comes into play.
This machine is designed for more than just making nails shiny. It performs several crucial functions:
- Deburring: Nail making can leave sharp edges or burrs. Polishing removes these, making the nails safer to handle and use.
- Lubrication: The polishing process can distribute a light coating of oil (if desired), which helps prevent rust and improves nail driving.
- Achieving Desired Finish: Polishing gives the nails a clean, bright finish, enhancing their visual appeal and perceived quality.
The machine typically consists of a loading mechanism, a rotating tumbling drum, and screens to separate sawdust. Sawdust? Yes! The secret ingredient in many nail polishing machines is sifted, dry sawdust from hardwood. This natural abrasive gently polishes the nails, removing burrs, oil stains, and minor rust. It’s a surprisingly effective and eco-friendly method I've seen used for years.
The result? Nails that are not only cleaner and smoother but also have enhanced anti-corrosion properties, making them ready for sale and use in demanding roofing applications.
Need Extra Protection? Consider a Galvanizing Line
For roofing nails, especially those used in exposed environments, corrosion resistance is paramount. Galvanizing is the gold standard for protecting steel nails from rust and extending their lifespan. An Electro Galvanized Line is an investment that significantly enhances the value and durability of your roofing nails.
In my experience, electroplating is one of the most effective methods for applying a protective zinc coating to metal parts. This line is designed to galvanize finished roofing nails (and other types of wire nails and screws, offering versatility).
Why galvanize? Because it dramatically improves the nail's resistance to corrosion, especially in damp or coastal environments. Galvanized roofing nails last significantly longer and maintain their structural integrity, which is crucial for roof longevity.
The galvanizing line utilizes polyethylene drums to process the nails. These drums are advantageous for several reasons:
- Higher Production: They allow for a much larger volume of parts to be treated compared to traditional hanging methods.
- Chemical Resistance: Polyethylene is highly resistant to the chemicals used in the galvanizing process, ensuring a long drum lifespan.
- Even Coating: The tumbling action within the drums promotes even zinc coating across all nail surfaces.

The Galvanizing Process (Simplified):
- Pre-treatment: Nails are cleaned and prepared for galvanizing through acid pickling and water rinsing.
- Electroplating: Nails are immersed in a zinc electrolyte solution within the PE drums. An electric current is applied, causing zinc ions to deposit onto the nail surfaces.
- Post-treatment: After galvanizing, nails are rinsed, passivated (to further enhance corrosion resistance), and dried.
The line includes various tanks for each stage of the process, a rectifier to provide the electrical current, a drying machine, and a crane for material handling. It’s a complete system designed for efficient and high-quality galvanizing.
