SIC 3357

This classification covers establishments primarily engaged in drawing, drawing and insulating, and insulating wire and cable of nonferrous metals from purchased wire bars, rods, or wire. Also included are establishments primarily engaged in manufacturing insulated fiber optic cable. Establishments primarily engaged in manufacturing glass fiber optic materials are included in SIC 3229: Pressed and Blown Glass and Glassware, Not Elsewhere Classified, while those manufacturing fabricated wire products from purchased wire are classified in SIC 3496: Miscellaneous Fabricated Wire Products.

INDUSTRY SNAPSHOT

Nonferrous wire manufacturers shipped $19.1 billion worth of products in the late 1990s, up from $15.2 billion in 1995. While shipment values increased, so too did the cost of raw materials and capital investment. The performance of specific industry segments varied at the turn of the twenty-first century. For example, copper wire shipments increased from $774 million in 1999 to $869 million in 2000, and shipments in the aluminum rolling and drawing sector increased from $1.48 billion in 1999 to $1.61 billion in 2000, while the nonferrous metal (except copper and aluminum) rolling, drawing, and extruding sector saw shipments decline from $6.19 billion in 1999 to $6.03 billion in 2000.

Manufacturers involved in drawing and extruding nonferrous wire and cable supply five primary markets with various types of products manufactured from aluminum and copper—the two most widely utilized nonferrous metals—and other nonferrous metals. These products, ranging from fiber optic cable to insect wire screening, are drawn or extruded from wire bars or rods, a process that essentially winnows the larger bar and rod shapes into wire or cable. The wire and cable is then insulated with assorted materials such as paper, rubber, or other materials, including polyethylene and polyvinyl chloride. Once insulated, the wire and cable is used in an assortment of applications, including wiring for residential and commercial buildings, communication networks, power distribution, automobiles, and appliances.

Historically, the five primary markets for the industry's products have been communication industries; electric utilities; automobile, truck, and boat manufacturers; the construction industry; and manufacturers of home appliances and industrial machinery. Since the conclusion of World War II, the composition of the industry's primary markets has remained unchanged, although the order of importance of each market to the industry has fluctuated.

ORGANIZATION AND STRUCTURE

In the nonferrous wire drawing and insulating industry, approximately 380 companies in the United States were deriving the bulk of their revenue from the fabrication and insulation of wire and cable at the close of the twentieth century. These companies, many of which owned more than one manufacturing establishment, operated roughly 545 separate manufacturing facilities. Of these facilities, 357—or nearly 65 percent—employed 20 or...
