BOARDS
- Spruce
- Pine
Boards Boards can be produced from any kind of tree, but Spruce and Ponderosa Pine are the two most commonly used species. Both of these species have strong, beautiful characteristics, yet there are some differences found within these two. Ponderosa Pine tends to have larger knots, but these knots are spread throughout the lumber. Spruce has smaller, tighter knots, which are more consistent throughout the boards. Ponderosa Pine is easier to stain, but Spruce accepts a pattern more readily. While boards are mostly used for trim work, and fascia; small craftsmanship is also another common use.
DIMENSION
- Western SPF
- Hem Fir
- White Fir
- Douglas Fir
- Southern Yellow Pine
Dimensions Dimension is the name given to lumber that has been cut to standardized sizes of width and height in inches. Dimension lumber is most commonly used to frame walls, floors and roofs. Logs are sawn into rough size lumber or cants, then edged and sawn again to final dimension and cut to length. Dimensional lumber is used for housing and commercial construction.
LONGS
- Douglas Fir
- Hem Fir
- Spruce
Longs Long length cuttings are commonly used in roof rafters and flooring. Long lumber, up to 32' in length, is best used for housing and commercial construction.
STUDS
- SPF & ESLP
- Finger-Joint SPF
- Hem Fir
- Douglas Fir
Studs Studs, traditionally, are 2 x 4 pieces of lumber used for framing basic buildings in residential construction. They are considered one of the most basic and simple building materials. A stud has nominal dimensions of 2" to 4" thickness and 2" to 6 " widths. Studs are separated into three different categories: construction, standard and utility.
SELECTS
- Douglas Fir
- Ponderosa Pine
- Radiata Pine
Selects Selects are clear, finished lumber for finishing products and are graded specifically for their appearance. Selects are primarily used for trim, cabinetry or anywhere finished appearance matters.
PLYWOOD

Plywood By gluing a number of thin veneers or plies of softwood or hardwood, the first engineered lumber was created: Plywood. The specific type of glue and veneer determine the suitability of a sheet of plywood and its particular application. Each sheet of plywood is graded for exterior or interior use. Plywood is used in everything from construction to furniture. This is because plywood has great strength, low cost, and stability. Plywood is commonly used as a base under flooring or carpeting because it remains flat and gives a smooth, uniform surface that will not split or crack. Plywood is also useful for wall paneling because it helps against wind, earthquakes, and the settling of a house, while also providing thermal protection. There are many uses to plywood, making this piece of lumber a great choice. Cook County Lumber is proud to supply plywood from Roseburg, Murphy and Hoquim.
TIMBERS
- Douglas Fir



Timbers Timbers provide a skeletal-like frame, which supports an entire building/structure, including fence posts. Traditionally, timbers were driven face out, begged together, and then in filled. This produced a visible frame from the inside, out. Today, timbers still provide great structural support with fewer, larger pieces of lumber, while also providing aesthetic and structural benefits. Vertical timbers are also known as posts, which support structures at corners or other major uprights. Horizontal timbers include sill beams, noggin-pieces, and wall plates. And sloping timbers provide trusses and braces. Timbers provide great structural support in new numbers!

Cedar Cedar lumber is a great choice for decking, siding, paneling or any house project. Cedar has a natural resistance to moisture, decay and insect intrusion. With unmistakable dimensional stability, cedar lumber lays flat and straight. These boards retain fasteners and are sure to stay firm and solid throughout the life of your house. With a cellular structure that creates interior air spaces, cedar provides great insulation, better than most woods and higher than brick or concrete. This creates a cooler house in summer, warmer in winter, and helps absorb sound. Although cedar provides a great base for stains and paint, cedar is naturally a beautiful wood. With fine grain and texture and warm tones, light amber to deep honey, cedar makes a durable and beautiful choice.

Pattern Patterned lumber is largely associated with early American Décor but with modern technology, new patterns create modern finishing lumber. Most patterns are reversible providing a choice of pattern or surface finish in one board. Patterned boards are inspected and graded on the pattern or face side, but the back face can add to the design (which may be a lower the grade). There are many different patterns, and each pattern has a style and number. For example, Tongue and Groove, Beaded Ceiling, WP-4, and Car Siding are just a few patterns available.
