made up of laminae or thin layers. lumber lumber, term for timber that has been cut into boards for use as a building material. The major steps in producing lumber involve logging (the felling and preparation of timber for shipment to sawmills), sawing the logs into boards, grading the boards according to strand plants in NorthAmerica
In less than two years, Kenora will have the only Timber Strand plant utilizing hardwood hardwood: see wood.

Hardwood trees are deciduous trees, except in the warmest regions. resources in Canada, one of only three in North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. .
A few environment approvals need to be cleared before construction can begin on the $255-million laminated strand lumber (LSL (Link Support Layer) A common interface for network drivers.

After graduating, he coached at Mount Carmel High School (Chicago) and won three successive city championships. , who will be plant manager;
The approval process is going well, Brennan says, with construction on the 300,000-square-foot plant expected to start later this spring and the plant to be operational by mid-November 2002.
Kenora was chosen because of the available wood supply, its location close to Canadian and western U.S. markets, and the available workforce, Brennan says. The only other TimberStrand plants are in Deerfield, Minn., and Hazard, Ky. and were built in the early 1990s.
The plant, to be built on a 65-hectare site on Jones Road will employ about 190 workers in the mill and another 200 in woodland operations and related work. Spinoffjobs have been estimated at another 180 to 200 positions.
Trus Joist, a Weyerhaeuser company and leading manufacturer of engineered lumber products, developed the high-tech, proprietary TimberStrand LSL process in the early 1990s to utilize small-diameter, fast-growing trees such as poplar Poplar, city, England

Construction materials which, because of their ability to withstand external forces, are considered in the design of a structural framework.
Brick is the oldest of all artificial building materials. . The process uses most of the tree, leaving little waste.
TimberStrand replaces traditional sawn lumber products. The lumber replacement, as a structural material, is strong, straight and consistent, said Brennan, and not subject to twisting, warping or bowing.
The hardwood logs are conditioned and debarked before being sliced into strands about 13 inches long, an inch to an inch-and-a-half wide, and between 0.03 and 0.05 of an inch thick.
After drying, the strands are coated with adhesive and wax in a blender, and conveyed to the forming lines, aligned and deposited in a mat of the required mass. The combination of alignment and mass controls the mechanical properties of the thickness produced.
This continuous mat or billet is approximately eight feet wide and is cut to 35- or 48-foot lengths. The billet is pressed using a heated process where densification and adhesive curing occurs.
After pressing and cooling, the billet proceeds through a sander for final sizing and is cut into finished dimensions. The thickness ranges from 1.25 inches to approximately 4.0 inches.
LSL is used in window and door headers, wall studs A wall stud is a vertical member in light frame construction. Traditionally, studs were made of wood, usually 2×4 or 2×6 dimensional lumber. In North America, studs are typically placed 16 inches (400 mm) from each other's centre, but sometimes also at 12 inches (300 mm) or 24 , rim boards, and in industrial uses such as core material for windows and doors, furniture framing and concrete forming.
None of the value-added processes will be done in Kenora, he says.
"But Trus Joist could put in an I-joist plant down the road" if things go well, Brennan adds. The company already manufactures engineered wood products in Delta, B.C., and Claresholm, Alta., as well as at plants in the U.S.
The plant was first announced in November 1999, but the takeover of Trus Joist by Weyerhaeuser, already a shareholder due to its purchase of Canadian lumber giant MacMillan Bloedel, delayed the process.
