Evening Republican, Volume 22, Number 154, Rensselaer, Jasper County, 30 June 1919 — Spray Painting Corrugated Steel. [ARTICLE]

Spray Painting Corrugated Steel.

The corrugated steel used for airplane hangars in this country and overseas was painted before shipment. Owing to the large quantity of steel, it was out of the question to do this work by hand and machines could not be used on account of the corrugations. For this reason, a spray system of •painting was employed. First, the sheets were coated with red lead before being corrugated, and after that they received a coating of green on one side and gray on the other sijle, applied by means of a jet 14, Inches wide. —Scientific American.
