Steel preservative paints : prevent corrosion induced by acids, alkalis, moisture and other rust-producing agencies.
A 1926 trade catalogue published by Toch Brothers of New York, promoting steel preservative paints to architects, engineers and builders against rust and corrosion. The photographs show large steel-framed buildings and a steel truss bridge, presented as evidence of protected structural steel in urban settings; a designer might take from them the monumental stone-and-steel city architecture of the period, with grid-like window rhythms, setbacks and Art Deco ornament, and the industrial bridge trusses seen against overcast skies.
