Corrosion Protection

As a steel garage protects the cars within from the effects of nature, so hot-dip galvanizing protects the steel itself from deterioration due to damaging rust and corrosion. To preserve your frame long into the future, take advantage of the extended, maintenance-free lifespan attributed to hot-dip galvanized steel structures.

Galvanizing protects steel from the inside out, utilizing both tough barrier protection and intrinsic cathodic protection created during the coating process to defend against corrosion. The zinc coating created during the hot-dip galvanizing process is harder than the substrate steel, providing a tough-to-penetrate barrier that will defend the steel against the corroding effects of exposure, guarding the steel from corrosive moisture and vehicle pollutants.

The metallurgical reaction that occurs during the galvanizing process also protects the steel cathodically meaning nicks and scratches (up to ¼ in. diameter) exposing the substrate steel will be protected from corrosion by the sacrificial properties of the surrounding zinc. This makes galvanized steel particularly well-suited for the potentially rough garage environment, where vehicles may bump or scratch exposed beams.

Corrosion protection is extremely important to the preservation of the frame structure, as rust can shorten the lifetime of the garage. By hot-dip galvanizing steel elements, the garage can have gleaming corrosion protection that will defend and uphold the structure for generations.

Now that you are familiar with the corrosion protection provided by galvanized steel, we can translate how these advantages turn into economic benefits.
