Galvanizing Basketball Goals for Rust Resistance
Hot-dip galvanizing is the process of dipping fabricated steel, in this case basketball goals, into a kettle or container of molten zinc. While the steel is submerged in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel. This process is use when the steel in the final product will be subjected to harsh weather conditions, corrosive situations and other damaging environments.
The term "galvanizing" is often used incorrectly to describe various zinc coatings for steel. The hot-dip galvanizing process used for basketball goals is after-fabrication hot-dip galvanizing and is not the same as in-line or continuous sheet galvanizing. Continuous sheet galvanizing, a coil-to-coil process used on 10-28 gauge sheet steel, is produced in a slightly different process. For basketball goals the process is applied after all of the parts have been fabricated or welded. The Raider basketball goal and the Viking basketball system use the hot dipped galvanizing process.
In addition to hot-dip galvanizing and continuous sheet galvanizing, there are a number of other zinc coatings applied to steel such as zinc-rich paint, electro-statically applied (plated) zinc, metallizing, and mechanically applied zinc. All of these zinc coatings are significantly different than hot-dip galvanizing and may be inappropriate for many situation and environmental exposures. The Destroyer basketball goal uses a zinc powder coating hat is baked on in a furnace before the final black powder coating is applied and baked on.
