Extended NAICS Code 331221-01 - Metals-Corrugated (Manufacturing)

Extended NAICS Code 331221-01 Description (NAICS 8-digit)

Metals-Corrugated (Manufacturing) is a subdivision of the NAICS Code 331221 that involves the manufacturing of corrugated metal products. Corrugated metal is a type of sheet metal that has been formed into a series of parallel ridges and grooves, which provide additional strength and rigidity to the material. This industry is responsible for producing a wide range of corrugated metal products that are used in various applications, including roofing, siding, fencing, and decking. The manufacturing process for corrugated metal involves several steps, including cutting, rolling, and shaping the metal sheets. The metal sheets are typically made from steel, aluminum, or other metals, and are coated with a protective layer to prevent rust and corrosion. The sheets are then fed through a series of rollers that create the characteristic ridges and grooves of corrugated metal. The finished products are then cut to size and packaged for shipment. Metals-Corrugated (Manufacturing) is a highly specialized industry that requires a range of specialized tools and equipment to produce high-quality corrugated metal products.
