Nothing less. No exceptions.
High quality steel without any defects. It is made to order by producers or purchased from stockholder's inventory. Prime steel includes full mill certification since it has passed all manufacturing inspections.
Surplus steel that is leftover for various reasons but is otherwise perfectly usable and possibly even of high quality. Obtained due to an over-order, miscut, canceled project, location closure or it was simply overstocked.
Ideal for applications that don't require the stringent quality controls that prime metal does. A few dings or aesthetic flaws don't matter when your material is getting painted, coated, or going non-visible application.
Following HD GALV coating process, the strip is immediately run through an annealing furnace and then recoiled. This step anneals the zinc coating to the steel strip. Iron in the base metal combines with zinc coating.
Similar to HD Galv process, but the molten bath is comprised of 55% Zinc and 45% aluminum. Galvalume has superior corrosion resistance and is primarily used in metal building applications.
