Galvanized steel strip is a material produced by continuous hot-dip galvanizing process with hot-rolled steel strip or cold-rolled steel strip as the substrate. Hot-dip galvanized coils are supplied in coils after coiling; hot-dip galvanized sheets are supplied in rectangular flat plates after cross-cutting, and galvanized strips can be obtained by cutting the plates.

Galvanized steel strip has good coating adhesion and weldability, and can be directly processed, with strong corrosion resistance, good surface quality, benefit from deep processing, economical and practical, it is used for construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, The electrical industry has provided a new type of raw material, especially the steel structure construction, automobile manufacturing, steel silo manufacturing and other industries, which has achieved good effects such as replacing wood with steel, efficient construction, energy saving, and pollution prevention.

However, in different regions and different parts of use, the service life of color-coated boards with the same amount of galvanizing, the same coating, and the same coating thickness will be very different.
