Success and failure in British Columbia's softwood plywood industry, 1913 to 1999

Griffin, Robert Brian 15 January 2018 (has links)
British Columbia's plywood industry between 1913 and 1935 bore little relationship to the industry of the post-World War II period. In 1913, the Canadian Western Lumber Company's Fraser Mills plant manufactured Douglas fir plywood, but until the late 1930s the largest part of its production was used in door manufacture. Two cottonwood plywood manufacturers, Laminated Materials Company (1913–1931) at New Westminster and the British Columbia Veneer Works (1928–1945) at Nelson, sold their plywood for interior wall paneling and specialty uses such as packing crates. The opening of the H. R. MacMillan Export Company's (MacMillan Bloedel) Vancouver plywood plant in 1935 and its Alberni plant, built in 1942, began a new era of plywood production. Sanded Douglas fir plywood dominated sales. The major producers (MacMillan Bloedel, Canadian Forest Products, Crown Zellerbach, British Columbia Forest Products, and Weldwood), assisted by the Plywood Manufacturers Association of British Columbia, targeted customers and created demand for waterproof Douglas fir plywood. The major producers established a network of wholesale warehouses across Canada and used these warehouses as a competitive strategy to develop and influence sales. The major manufacturers after World War II used the high profits generated by Douglas fir plywood to assist their expansion into integrated forest products. Each company chose a different strategy of expansion and adapted its plywood production to suit its corporate goals. Plywood became one product among several and declined in importance for each company. By the 1970s substitute products such as oriented strand board were being promoted as replacements for plywood. Cheaper production costs and the use of waste wood fibre, instead of high quality Douglas fir logs, meant that government and industry favourably viewed the substitute products. The high value of old growth Douglas fir logs and increased costs in all aspects of production resulted in the closure of all but one coastal plywood plant, Richmond Plywood, by 1999. Exports were a small percentage of total plywood sales and did not compensate for declining domestic demand. The interior plywood industry was re-established in 1951 with the opening of Western Plywood's Quesnel plant. A number of plants, scattered throughout the interior, produced plywood using small logs and species other than coastal Douglas fir. Production was mainly sheathing used to clad building floors, roofs, and walls. The scattered nature of plant location, cheaper log costs, small log processing technology, and different harvesting tenures contributed to the success of interior plywood production. The large producers closed their coastal plywood plants arguing that production costs were too high and that other products were replacing plywood in the marketplace. The prosperity of interior plywood manufacturing suggests that the coastal industry stopped production because neither government nor manufacturers saw any reason to seek viable alternatives. The forest industry's diverse nature and its perception of future, based on past activities, supported the closure of the coastal plants and the continued survival of the interior plants within a new forest economy. / Graduate

Effect of Multiple Knots in Close Proximity on Southern Pine Lumber Properties

Barbosa, Marcela Cordeiro 14 December 2018 (has links)
This research investigates the effect that knots in close proximity have on strength properties of southern pine lumber. The project involved specimens of 2×4 dimension southern yellow pine lumber exhibiting multiple knots in close proximity. Knot dimensions were measured to determine the knot diameter (KD) parallel to the cross-section of the specimen, knot area (KA), and clear wood (CW). In addition, the density (D) using the entire specimen weight by volume was determined. A third-point bending test was used in a flatwise orientation to quantify the modulus of rupture (MOR) and modulus of elasticity (MOE). The relationships between the simple correlation coefficients showed significant correlation. Multiple regression analysis with one dependent variable, MOR, and three independent variables, KD, MOE, and D resulted in a coefficient of determination value (r2) of 0.702 as contrasted with 0.564 obtained by using MOE alone to predict MOR.

Production Structure, Input Substitution, and Total Factor Productivity Growth in the Softwood Lumber Industries in U.S. and Canadian Regions

Li, Jingjing 15 February 2010 (has links)
This study uses a translog cost function to specify the production structures of the softwood lumber industry in three U.S. regions (the West Coast, the Inland, and the South), and four Canadian regions (Ontario, the British Columbia Coast, the British Columbia Interior and Quebec), from 1988 to 2005. First, two separate production models are specified and analyzed, one is a “U.S. model” for the U.S. regions, and the other is a “Canada model” for the Canadian regions. Second, all seven regions are included in one production model, a “U.S.-Canada model”. In the U.S.-Canada model, purchasing power parity over the Gross Domestic Product is used to convert cost and price data of Canada from Canadian into U.S. dollars. The Allen and Morishima elasticities of substitution, price elasticiteis of demand, rate of technical change, and total factor productivity growth are estimated in each model, and the results are presented and compared.
