Four species, White Spruce (Picea glauca), Engelmann Spruce
(Piceaengelmanni), Lodgepole Pine (Pinus contorta), and Alpine Fir
(Abieslaciocarpa) comprise the spruce-pine-fir species group. All yield
high grade timber with relatively small, sound tight knots. Lumber
produced from spruce-pine-fir Species is marketed together as SPF.
SPF lumber is a distinctly white wood, with very little color variation
between springwood and summerwood. The wood has a bright, clean
appearance, ranging in color from white to pale yellow, with a fine
straight grain and smooth texture.
Uses:
Kiln dried SPF lumber is used as a structural framing material in all
types of residential, commercial, industrial and agricultural building
applications.
Kiln dried SPF lumber is also used extensively in the manufacturing of
prefabricated housing, trusses and other structural components. In
addition to producing high quality structural lumber, with a little
preparation, SPF can be made into very appealing, economical solid wood
furniture.
Products:
Structural lumber, trusses, prefabricated housing, exterior decking,
preservative treated poles, railway ties, outdoor furniture. Transco Mills produces top quality tongue and groove SPF decking.
Technical
Specifications:
SPF lumber is seasoned uniformly in dry kilns to a moisture content of
19% or less. Kiln drying inhibits natural staining of the wood,
improves its strength and stiffness, enhances its appearance and
increases its resistance to decay and attack by insects.
SPF has a high strength-to-weight ratio and is well known for its
outstanding working properties. It takes and holds nails exceptionally
well and is easily worked with hand and power tools. It has good
gluing, painting and staining properties.
Transco
Decking is available from selected
lumberyards and retailers in Canada and in the USA.
