Pregalvanized steel is zinc coated by a hot dip process. Steel strip from a coil is fed through a continuous zinc coater which cleans, fluxes and coats the steel with molten zinc. After cooling, the steel is recoiled.
The pregalvanized zinc coating conforms to a G-90 thickness designation per ASTM A653.
The zinc thickness is .75 MIL or .45 oz./sq. ft. of surface area.
This coating is offered on Unistrut channel and tubing and is a well-proven, time-tested performer for indoor and outdoor applications.
