Spin galvanizing
The LoneStar Group offers spin galvanizing solutions to protect threaded or precision components, including fasteners, bolts, nuts, washers and fixings.
This process offers the same benefits of hot dip galvanizing but ensures clean and uniform coatings on the finest of parts and threads.
Complex parts. Consistent quality
The LoneStar Group works with approved manufacturers who use galvanizing and centrifuge systems, allowing us to offer both hot dip and spin galvanizing solutions to our global critical-industry customers.
While hot dip galvanizing is used for larger components, spin galvanizing is required to protect smaller parts that can become lost, damaged or unevenly finished in the zinc-coating process.
Spin galvanizing
This process involves placing metallic components in a dip basket, which is then submerged in molten zinc, withdrawn and spun at high speeds within centrifuge systems. Through controlled spinning, excess zinc is consistently removed from all parts, resulting in a clean, uniform finish throughout the batch.
Benefits of galvanizing
Unlike surface-level coatings such as paint, the zinc chemically bonds to metal, making it stronger against wear and corrosion. This galvanized zinc coating is also thicker than alternatives, further contributing to its strength and durability to enhance performance lifespans while reducing maintenance cycles and replacement costs.
In addition, galvanized steel exhibits self-healing properties due to the electrochemical bond between zinc and steel. When minor scratches or damage occur, zinc migrates to the affected area, providing a new layer of zinc oxide, which in turn provides a degree of protection. Galvanizing only ever uses the exact amount of zinc required for a batch, further reducing materials costs and environmental waste.
- Excellent protection and resistance to corrosion
- Uniform coating even on complex shapes and threads
- Mitigates clogging, coating high-performance parts that fit and perform as required
- Maintains thread integrity even on the smallest of critical fasteners
- Suited to high-volume production runs of repeatable small parts
- Strong metallurgical bonds and protection (zinc becomes part of the steel surface)
