G40 Galvanized Coil

Galvanized Steel Coil

Galvanized coil is made of hot-rolled or cold-rolled steel strip as the substrate, which is divided into hot-dip galvanizing and electrogalvanizing.

G40 Galvanized Coil

Galvanized steel coils are covered with a zinc coating to provide corrosion resistance. G40 galvanized steel coil is a galvanized layer name or A653 standard specification specified in the hot-dip coating process galvanized or zinc-iron alloy steel coil requirements.

G40 Galvanized Coil Description

The coating designation G40 represents the type of coating and the weight of the applied coating. The letter "G" indicates that the coating is galvanized, meaning zinc-based. Meanwhile, the number "40" represents the thickness of zinc on the surface of the steel coil. Galvanized steel coil is covered with a zinc coating to provide corrosion resistance. The G40 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G40 is the average coat weight and therefore provides moderate protection.
