Centrifuge / Spin Galvanizing
Dedicated Centrifuge/Spin Galvanizing Plant
Spin or Centrifuge Galvanizing is the process used on smaller steel parts, such as nuts, bolts and screws.
The Process
This follows the same process as general galvanizing except that the work is placed in baskets to be galvanized, so they are not lost in the bath. They are removed from the bath before the zinc on the work solidifies.
The basket is placed in a centrifuge and spun for several seconds to remove excess zinc from the surface and prevent items from sticking together, ensuring a smooth finish. This is especially important for nuts and screws with threads to ensure the threads are clear of excess zinc.
FAQs
Hot dip galvanized steel will last very well in most environments. It is not uncommon for galvanized steel to last more than 70 years under certain conditions. Latest corrosion rates can be found at the Galvanizers Association
The three intermetallic layers that form during the galvanizing process are all harder than the substrate steel and have excellent abrasion resistance.
“White Rust”, or wet storage stain, is formed because zinc on newly-galvanized steel is very reactive and quickly forms zinc oxide and zinc hydroxide corrosion products that go on to become the stable zinc carbonate.
When galvanized steel is stacked damp, stored in wet boxes or shrink wrapped with no free-flowing air, the zinc forms excessive layers of zinc hydroxide, otherwise known as wet storage stain.
Most wet storage stain can be easily removed with a nylon brush. To prevent wet storage stain, store galvanized steel indoors and in such a way to allow free-flowing air between each galvanized item.
