![]() The largest lumber manufacturing regions in the world are: China (18%) United States (17%) Canada (10%) Russia (9%) Germany (5%) Sweden (4%). ![]() Different areas of the world are recognized as significant timber suppliers however, these areas (Indonesia, Sarawak, New Guinea, etc.) are exporters of raw logs and do not have a significant domestic lumber producing industry. Historical wood-frame home building regions are: Europe, North America, China. Lumber manufacturing globally is determined by the preferred style of building areas with a "wood building culture" (homes were built from wood rather than other materials like brick) are the countries with significant sawmilling industries. This method produces the widest possible boards with the least amount of log waste. Each additional cut is then made parallel to one before. Plain sawn lumber is produced by making the first cut on a tangent to the circumference of the log. Lumber is the most common and widely used method of sawing logs. The basic understanding of lumber, or “sawn planks,” came about in North America in the seventeenth century. Plastic fiberglass structural lumber can have a "class 1 flame spread rating of 25 or less, when tested in accordance with ASTM standard E 84," which means it burns more slowly than almost all treated wood lumber. Blending fiberglass in plastic lumber enhances its strength, durability, and fire resistance. Its introduction has been strongly opposed by the forestry industry. Structural lumber may also be produced from recycled plastic and new plastic stock. (In the UK, the word lumber is rarely used in relation to wood and has several other meanings.)įurther information: Plastic lumber, Fiber-reinforced composite, and Wood-plastic composite In contrast, in Britain, and some other Commonwealth nations and Ireland, the term timber is used in both senses. In the United States and Canada, milled boards are called lumber, while timber describes standing or felled trees. It is more commonly made from softwood than hardwoods, and 80% of lumber comes from softwood. įinished lumber is supplied in standard sizes, mostly for the construction industry – primarily softwood, from coniferous species, including pine, fir and spruce (collectively spruce-pine-fir), cedar, and hemlock, but also some hardwood, for high-grade flooring. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. Beside pulpwood, rough lumber is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. ![]() Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. Lumber is sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (including the United States and Canada) the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. ![]() Lumber has many uses beyond home building. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber is wood that has been processed into uniform and useful sizes (dimensional lumber), including beams and planks or boards. The harbor of Bellingham, Washington, filled with logs, 1972 ![]()
