scope:

This specification covers a one coat shop-applied primer for open web and long span steel joist and joist girders and for cold formed steel framing, and primary and secondary structural framing for metal buildings. This coating is intended to provide temporary protection to the steel joist during delivery, storage on site, and erection in an atmosphere comparable with SSPC Environmental Zone 1, normally dry. This coating is intended to be used as a holding primer that may or may not be removed before or after erection or assembly in the field.

The specification does not address the formulation of the coating but covers the physical and performance characteristics of the coating.
