Galvanized Sheet Steel G90

In the realm of steel doors and frames there are three types of galvanized and galvanneal steel used a40 a60 and g90.

Galvanized sheet steel g90.

These coating weights are a total for both sides of the strip. Galvanized steel sheets are easy to weld form and drill. Commercial steel deep drawing steel and extra deep drawing steel are designations described in the astm specifications for steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process a653 a653m. For example g 90 designates a zinc coating of 90 oz square foot while g 140 designates a zinc coating of 1 40 oz square foot.

G90 galvanized steel sheet astm a527 a653 galvanized steel sheets are intended for usewhere greater corrosion protection is required without painting. Galvanized g90 flat sheet standard mill sizes for galvanized g90 flat sheet range from 28 gauge 018 thick all the way up to 8 gauge 1681 thick. Galvanized steel sheet plates are intended for use where greater corrosion protection is required without painting a lower cost alternative to stainless steel galvanized sheet and plates have a rust free protection for up to 30 years while maintaining strength with a durable surface coating. The differences in the three are based on the percentage of galvanneal coating per square foot and the protection they offer.

Batch galvanizing coating specifications are given in weight per surface area. The galvanized sheet coating parameters relate to the total for both sides of the sheet. G 90 and g 140 are coating designations for galvanized steel. The standard product is class g90 which has 0 9 oz ft 2 of sheet total both sides or about 0 76 mils 18 µm thickness per side.
