This specification covers the material requirements for a Basic Lead Silico-Chromate, Oil-Alkyd Paint System intended for use on exterior iron and steel structures (bridges), for either new or re-paint work, except where exposed to severely corrosive conditions such as within the splash-zone from bridge decks or on other members likely to be affected by de-icing salts or persistent moisture conditions. This system shall consist of a primer-, intermediate-, and finish-coat paint as hereafter specified. Uses of the component paints other than as an integral part of this system are specifically excluded.
