Does Galvanized Steel Rust?

Rust corrodes and damages metal, leading to structural damage. Should you worry about your metal roofing or metal siding panels? Galvanization provides a protective zinc coating over the top of steel. This coating offers extra protection and prevents rust. Unlike paint, which only provides minimal safeguarding against corrosion, galvanization gives your metal roof at least a half-century of durability.

How Does Galvanization Work?

Corrosion, in a nutshell, deteriorates metal when oxygen attacks iron. The iron oxide created will flake away over time. If left alone, eventually, the entire metal siding panels or roof will rust and deteriorate considerably. Aluminum and stainless steel have a special oxide layer that limits corrosion. Applying a special zinc layer on top of steel, the design ensures water and oxygen cannot reach the metal. This is galvanization.

In some cases, the galvanized steel does not hold up as well to the elements. Why? Galvanized steel may not last as long in humid environments, extremely water-soaked environments, places with acid rainwater, or even where saltwater is prevalent. Local environmental conditions affect the durability and quality of the metal over time. For example, you would not want to use galvanized metal for the interior of a car wash where constant high-pressure moisture affects the panels for the bulk of the day.

Long-lasting and Reliable

Despite all of these circumstances, surprisingly enough, galvanized steel last for decades and decades. Most homeowners install a metal roof and don’t have to worry about replacing it again in their lifetimes. Galvanized steel has been in use for centuries. Metal roofing works for a variety of applications, including: 

  • Residential Homes
  • Commercial Buildings
  • Industrial Warehouses
  • Medical Buildings
  • Temperature-Controlled Storage Facilities
  • Agricultural Facilities
  • Architectural Institutions
  • And more

Additionally, galvanized steel can be used in environments exposed to industrial pollutants, tropical areas, frigid climates, underground, and even in extremely high temperatures. Finding a material that durable can be difficult. Galvanized steel offers superior protection to more traditional materials like wood or asphalt.
