Comparison of two other differences between coating steel and stainless steel

# Comparison of powder coating and stainless steel on environmental issues

Powder-coated steel can provide a color lasting finish that stands in most environments. The high-density particles used in the powder coating form a protective layer on the metal surface, preventing indentations and scratches. The powder coating also protects against discoloration from sunlight. However, powder coatings usually only last 15-20 years, depending on the pretreatment of the metal and the type of powder coating material used.

The chromium in stainless steel makes it very resistant to damage over long periods of use. Stainless steel can withstand high and low temperatures, from cold storage areas to hot outdoor environments. Stainless steel holds up well in sunny and humid conditions. In fact, stainless steel is very resilient and has a long life in almost any environment.

# Powder coated steel or stainless steel rust and corrosion prevention?

Powder-coated stairs are usually resistant to corrosion. The powder coating itself does not corrode or rust, but if the powder coating is damaged or cracked, the steel underneath it will corrode or rust. This can be a particular problem if the steel underneath the powder coating is exposed to moisture or salt water.

Although stainless steel can rust, it can endure much longer. Stainless steel stairs will rust only in unusually harsh environments. There are different grades of stainless steel. The more chromium in stainless steel, the better its corrosion resistance. Because the chromium in stainless steel forms a protective layer on the surface, it does not rust even in wet conditions.

Other additives such as molybdenum help to further improve the corrosion resistance of stainless steel. For example, adding molybdenum to grade 316 stainless steel makes it more resistant to harsh chemicals than grade 304 stainless steel. Whether 304, 316 or other grades of stainless steel, stainless steel stairs will remain smooth and shiny even after prolonged exposure to water.
