In order to play a better anti-oxidation effect, the surface of the galvanized coil is usually lightly coated with oil, 2-80mg per square, which can temporarily block the contact between water and the surface.

We usually source hot coils from steel mills and cold rolled coils them in processing plants. Because it is galvanized on the basis of cold-rolled coils. There are many factors that affect HRC, such as the price fluctuation of iron ore, the price fluctuation of coke and the demand for HRC futures, etc., which will affect the price of HRC.

Here is a sample conversion directly associated with Z275:

1 oz/ft2 is equal to 305.15 g/m2

And to convert from ASTM standard to SI system, you need to multiply by 305.15

So if the ASTM weight designation is G90 (0.90 oz/ft2) , it will become Z275 (275 g/m2) in STI.

Z275 will directly be translated to a steel product with a Zinc coating, and the 275 as the weight of zinc applied on the surface of the steel.
