Sawmills and Plywood Mills

The US lumber and plywood manufacturing industry includes about 6,000 companies with combined annual revenue of about $55 billion. Large companies include divisions of Weyerhaeuser, Louisiana-Pacific, Georgia-Pacific, and Universal Forest Products. The industry is concentrated: the 50 largest companies hold about 50 percent of the market.

Manufacturers of wood windows and doors and wood flooring are covered in separate industry profiles.

Sawmills can operate with only a modest investment of capital, but plywood mills require expensive equipment and therefore are usually plants with high annual volume.

PRODUCTS, OPERATIONS & TECHNOLOGY

Sawmills process raw logs in a few simple operating steps. Logs are debarked and cut into "cants" that are further cut into finished pieces of lumber, using either circle saws or bandmills. Once lumber is cut to size, it may be sold as "green" lumber or may be stacked and dried to a specific moisture content through air- or kiln-drying. Kiln-drying involves stacking wood in shed-like structures and ventilating with hot air for ten to 30 days. Many sawmills produce a range of "dimension" lumber, lumber of various standard lengths, widths, and thicknesses. Some sawmills specialize in producing only "stud" lumber, ...
