Rough Cut – Random Widths – Random Lengths

Red Alder is stocked in two different grades: Premium Frame and Superior. Superior Alder is the top grade in Alder. It's primarily used for moldings and applications where clear faced cuttings are required.

Alder, when freshly cut, is very pale, almost white in color. As it begins to oxidize, the color grows deeper and takes on golden and red tones. Heartwood occurs only in trees of advanced age. The boundary between Alder sapwood and heartwood is virtually invisible. The wood has a fine, uniform textured with a straight, yet subdued grain.

Alder is a medium-density wood with low shock resistance and medium crushing strength. It is easily worked with both hand and machine tools and turns well. It has very good nailing and gluing properties. It is highly valued for upholstery framing, due to its stability and excellent tack- holding qualities. It stains and polishes well, producing a finish that blends beautifully with Walnut, Mahogany, or Cherry. The inconspicuous grain also makes Alder an excellent choice for painting.

Superior Grade Rule Summary: 83 1/3% Clear 1 Face and at least 66 2/3% on the back. Minimum clear-cutting size: 3" x 6' or 4" x 3' *Pin Knots are not a defect in Alder.

The following board foot calculator can be used to help you calculate your order.

Board Foot Calculator
The easiest and most common way to calculate board feet is to use a board foot calculator.
Several different board foot calculators are available online or check your app store and download to your phone.

To calculate board feet of lumber, use the following formula:

    Board Feet = Width (inches) x Thickness (inches) x Length (FEET) divided by 12.
    Example – For a piece of lumber 2 inches thick, 6 inches wide and 10 feet long, you calculate board feet as follows:
    Board Feet = (6 x 2 x 10) divide by 12 = 10 board feet.

If your order requires specifics, call to verify we have exactly what you need.
Example: If you order 100 board feet and need one board 8'6" that is at least 8" wide and one board 10' at least 6" wide – be sure to state exactly what you need.
