A60 and a40 are ratings for galvannealed steel.
Galvanized sheet metal grades.
Galvanized steel is a hot dipped coated metal that provides customers with better resistance to corrosive environments.
This standard is issued under the fixed designationa653 a653m.
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.
Steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process1.
Hsla grades 40 80.
For example 1010 steel is a carbon steel with a nominal 0 10 percent carbon level.
The sae j403 grade 1010 specification states that the steel may be supplied with carbon content from 0 08 to 0 13 percent.
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.
Both types a and g are available on a full range of steel grades from cs commercial steel through edds extra deep drawing steel.
To create galvanized steel cold rolled steel is submerged into a molten zinc bath known as the hot dip process galvanization can also be achieved through continuous galvanizing.
On the other hand in the case of sae j403 grade 1008 the spec allows for up to 0 10 percent carbon with no minimum.

This is a hot dipped process where the steel is heated after coating with zinc converting the zinc coating into a harder zinc iron alloy coating that is also smoother more scratch resistant and more paintable than a galvanized finish.

Metals depot stocks many sizes in precut sizes full mill sizes or we can hot dip virtually any.
Common applications range from construction framing and ductwork to machinery framing.
These grades have varying ability to be formed.
Continuous sheet galvanizing a variety of coating weights are available ranging from 0 25 mils 6 µm to just under 2 mils 50 µm per side.
Hot dipped galvanized is produced to meet astm a 653 specifications general requirements for steel sheet zinc coated by the hot dip process.
