Applies to establishments engaged in the construction of boilers or steel tanks. Boilers are tanks used to either store hot water or make steam. Tanks may be used to hold products such as, but not limited to, sand and gravel, water, solid waste or fuels. The product is constructed from steel plate and may use I-beams for structural support. The materials may be purchased in bulk, if the business has the brake presses and rollers to cut and shape the metals to the appropriate dimensions, or as fabricated components. These establishments may also use cutting torches and other welding equipment in the manufacture of their products. They usually have a large shop area in one or more buildings that is equipped with overhead cranes. There is usually a yard to store raw materials, work-in-process, and finished goods. This is a shop or plant only classification; it includes work being performed in an adjacent yard when operated by an employer having operations subject to this classification.

This classification excludes installation of boilers or tanks which is to be reported separately in the classification applicable to the work being performed.

Items manufactured include, but are not limited to, crab pots, gaff hooks, firewood boxes, rims for basketball hoops, and rebar. Raw material is cut to desired size with saws, shears, brake presses, punches, and flame cutters. Parts may be joined by welding, riveting, screwing, or bolting. The parts may be handled by overhead cranes, hoists, and forklifts. The products may be finished in a variety of ways including, but not limited to, sanding, grinding, cleaning with solvents and applying paint or lacquer. Finish work is included in this classification when performed by employees of employers subject to this classification. This is a shop or plant only classification; it includes work being performed in an adjacent yard when operated by an employer having operations subject to this classification.

This classification excludes establishments primarily engaged in structural iron or steel manufacturing which are to be reported separately in classification 5208; establishments primarily engaged in welding and machine shop activities which are to be reported separately in classification 3402; and establishments primarily engaged in manufacturing products from metal lighter than 9 gauge which are to be reported separately in classification 3404.

Applies to establishments engaged in the manufacture of wood or pellet burning stoves. Sheet steel or plate metal is sheared, formed, punched, baked and decreased. Parts are assembled by spot welding, then enameled or painted. Grey iron parts are foundry cast, chipped, and ground. Heating elements, insulation, wiring and control assemblies, glass panels and grey iron parts are assembled into stove shells on the production assembly line. The stoves are then packed for shipment. Materials include, but are not limited to, sheet steel, grey iron or ferrous castings, insulation materials, glass, aluminum and brass tubing control assemblies, chrome trim and hardware, and paints and enamels. Equipment includes, but is not limited to, power presses, shears, brake presses, welding equipment, spray painting equipment, baking oven, pneumatic and electric grinders and chippers, and pneumatic tools. This is a shop or plant only classification; it includes work being performed in an adjacent yard when operated by an employer having operations subject to this classification.
