Galvanized steel, while one of the strongest metal materials in the world, isn’t impervious to misinformation and myths. In fact, there are plenty of galvanized steel myths floating around that tend to mix with the actual facts.

Is your knowledge of galvanized steel up to par? If you can tell which of these statements is myth and which is fact, you’ll be an expert in no time.

Spangle size is a reflection of the amount of zinc present.
MYTH. While this may have been true in the past, technology has improved vastly over the last few years. Now, a smaller spangle and a smoother surface are both signs of a stronger resistance to corrosion. If you want your knowledge of galvanized steel to stay up to date, you should always keep your eyes peeled for steel suppliers’ news.

White rust doesn’t interfere with the structure of steel.
FACT. White rust is commonly referred to as storage stain, and can occur on stainless strapping left to the elements. It’s the result of steel, galvanized strapping in particular, coming into contact with water when stacked. Rust does cause a loss of zinc coating, but the amount of corrosion is minuscule in the vast majority of cases.

Wet galvanized sheets can be saved from white rust by separating them.
MYTH. If your stainless strapping is unpassivated, there’s a slim chance that you’ll be able to prevent any white rust from forming. Passivation minimizes the chances of white rust stains, and should be opted for while placing an order for steel as an additional protective measure. However, if you require unpassivated steel for a job, the best way to prevent white rust is to keep all of your steel 100% dry.

Steel can be stored for over a year without fluting or straining
MYTH. Ask any steel supplier. The maximum amount of time for steel to sit in storage is around six months. Any longer and issues will start to occur as the carbon begins to age.

Steel parts are up to 30% more durable than they were 10 years ago, but that doesn’t mean they’re invincible. Before you purchase steel or work with it, make sure your stainless strapping knowledge is up to par!
