SPF (spruce-fir-pine) English: Spruce-Pine-Fir

White spruce, alpine fir, and conifer pine, the three conifer species that make up the S-P-F (spruce-fir-pine) tree species combination, share many common traits and the same origin, so they are packaged together in Promote in the market.

SPF grows slowly in boreal temperate forests, resulting in densely grained, high-strength sawn timber with relatively small knots, ideal for construction use. In North American construction, SPF sawn timber is the most used primary lumber species. SPF sawn timber is a typical light-colored wood. The wood usually has a bright and clean appearance. The color ranges from white to light yellow. It has a dense straight grain and a smooth texture. Its drying properties are good. After kiln drying, its strength High and stable performance, with excellent machining properties, suitable for grooving and drilling, easy to nail or screw. SPF sawn timber is also easy to glue with a variety of adhesives and is suitable for direct and laminated timber. Kiln-dried SPF sawn timber is mainly used for the structural frame of various types of civil, commercial, industrial and agricultural buildings, and is also widely used in the manufacture of prefabricated houses, wooden truss roofs and other structural parts, and can also be used for terraces, houses Panels, decorative parts, etc. In addition to being used to produce high-quality structures, with a little processing, SPF wood can also be used to make very attractive and economical solid wood furniture.

Canada is rich in forest resources, of which SPF is the largest tree population. In terms of forest reserves, SPF accounts for about 17 billion cubic meters, and about 5.5 billion cubic meters in British Columbia and Albert. The commercial softwood species with the largest forest reserves of the species. Canadian-produced SPF sawn timber is lightweight, stable, easy to machine, beautifully textured, and available in plentiful supply, making it an excellent choice for building and structural timber. Every piece of SPF lumber produced in Canada has a grade stamp to identify the tree population, grade, drying condition, grading agency and manufacturer, which are certified and audited by the Timber Standards Institute Council for the quality of SPF lumber Provides the strongest guarantee.

Western Red Cedar English: Western Red Cedar

Western red cedar, commonly known as red cedar, is a special tree species with high stability (about 50% less shrinkage than other softwoods), light weight, and natural decay resistance. Western red cedar accounts for 20 percent of coastal mature forests. They can grow up to 30 to 45 meters in length and 120 centimeters or more in diameter. The color of the wood is usually reddish-brown, but can vary in color, between white (sapwood) and dark brown (heartwood).

Because of its natural decay resistance, western red cedar is ideal for building siding, roof tiles, doors and windows, outdoor patios, walks, fencing, fences, pavilions, and a variety of yard landscaping uses. The stability of western red cedar makes it an excellent choice where the exterior needs to be painted or stained. Due to its fine texture and natural stability, cracks rarely develop when subjected to wet and dry cycles. Western red cedar is an excellent choice for solid wood shutters due to its light weight and low deformation resistance.

The density, strength and hardness of western red cedar are lower than other coastal softwoods, so it is not usually used in building structures, but designers still specify this wood for appearance reasons, such as exposed beams and columns, etc. important place. Because of its warm tones, western red cedar is also often processed into interior wainscoting and suspended ceilings.

Douglas Fir English: Douglas Fir

Among Canadian conifers, Douglas fir is one of the most famous and popular. It accounts for 10% of BC's coastal forests. It is the tallest and stoutest of the coastal trees, reaching a height of 35 to 55 meters and a diameter of 120 centimeters.

Douglas fir has all the characteristics required for high-quality building materials: high hardness, high strength, high density, easy processing, less warping and some corrosion resistance. This species is widely used in structural and general buildings. Douglas fir is also the material of choice for glulam beams in heavy timber construction. Defect-free and processed-grade Douglas fir sheets are popular for use in doors and windows, finishing wood products, and more. It has excellent machinability and has a good bite on nails and screws. Due to its unique texture and reddish-brown appearance, it is usually only necessary to finish it with clear paint in actual use.

Hemlock English: Hemlock

Hemlock is the most grown tree species in coastal BC, accounting for 60 per cent of mature forests in the region. Typically 35 to 55 meters tall and 90 centimeters or more in diameter, hemlock wood is strong, hard, and dense (similar to Douglas fir), making hemlock ideal for construction and industrial use : It can be used as wood frame material, beam column, and engineering wood component. Hemlock is also amenable to pressure preservative treatment, making it the tree of choice when preservative-treated wood is required.
