Industry: 3443—Fabricated Plate Work (Boiler Shops)
Establishments primarily engaged in manufacturing power and marine boilers, pressure and nonpressure tanks, processing and storage vessels, heat exchangers, weldments and similar products, by the process of cutting, forming and joining metal plates, shapes, bars, sheet, pipe mill products and tubing to custom or standard design, for factory or field assembly. Establishments primarily engaged in manufacturing warm air heating furnaces are classified in Industry 3585; those manufacturing other nonelectric heating apparatus, except power boilers, are classified in Industry 3433; those manufacturing household cooking apparatus are classified in Industry 3631; and those manufacturing industrial process furnaces and ovens are classified in Industry 3567.
