Z120 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.

Z120 Galvanized Coil

Z120 is the coating name, which means that the coating thickness on both sides is approximately 120g/㎡ or 36g/㎡ (three-point test). Z120 grade galvanized coil is coated with zinc to make it more durable.

Z120 Galvanized Coil Description

Galvanized coil is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. Galvanizing is a well-known and effective method to add a protective layer to prevent the exposed steel from being corroded by natural elements. Zinc not only acts as a barrier between the environment and the steel, but it also decomposes first to protect the underlying steel and extend its service life. Zinc is generally represented by Z. Z is the abbreviation of English Zinc. Z120 means that the galvanizing content is 120 grams per square meter. The number after Z indicates the average coating content at three points on both sides of the galvanized steel in grams per square meter.
