G90 Hot Dipped Galvanized Steel is a hot-rolled galvanized steel with a galvanized layer weight of approximately 275 grams per square meter.

G90 is a code used in the American ASTM standard (ASTM A653/A653M) to describe the thickness of galvanized layers. Its meaning is: The total weight of double-sided galvanizing is 0.9 ounces per square foot (approximately 275 grams per square meter), corresponding to the Z275 mark in the European steel standard.

The lifespan of G90 coating in ordinary atmospheric environments can reach over 50 years, far exceeding G60 (180 grams/square meter) and G40 (120 grams/square meter).

Architecture field: Roof panels and steel structural frames (such as ASTM A653 Grade 50), have a service life extended by 3-5 times.

Automobile manufacturing: Replace high cost stainless steel with car body panels and exhaust pipes.

Agriculture: Grain storage and irrigation systems, resistant to chemical fertilizers and moisture corrosion.

A: Yes, the only difference between the two is the unit, G90（ASTM）≈Z275（EN）。

A: It is recommended to use a heavy coating (such as Z600) or additional anti-corrosion treatment. The lifespan of single-layer G90 in seawater is about 10-15 years.

A: Zero zinc flowers are suitable for spray pre-treatment, while large zinc flowers are used for decorative exposed structures.
