Grades and timber flooring.
Within Australia
there are usually 3 grades of timber flooring. These are Select, Standard &
Better & Feature grades. In the last few years [at 2013] other grades have
slipped in. Standard, Feature & Better & Low Feature. Essentially mills
must decide how best to capitalise on the timber that they produce to value add
the logs that they receive.
All of these grades apply to the aesthetic area of the
timber [how the face looks.] All of the grades are sound, suitable for use in
flooring and all are quality offerings. One is not inferior to the other, they
are simply different to look at.
In order to produce select and standard and better grades
there is some waste produced as gum marks at the ends of boards may be docked
off and the timber discarded. The labour components and the wasted timber adds
cost to the production and therefore these timbers attract a premium.
At times a mill may have a lot of feature grade but also
some shorter clear boards. This may be supplied as a feature and better grade
of flooring.

Overseas the grades often follow different lines. Instead
of gum marks the timbers may have knots and other pin holes, birds eye etc. Knots
are not an issue as long as they are sound. Again the grading follows aesthetics
going from rustic-feature-standard-standard plus & prime. The most popular
grade is usually standard grade as this allows for better overall lengths of
timber. [With some timbers it is rarely possible to get long lengths and clean timber faces so the 'so-called higher grades' are often shorter lengths.] Each mill offers their reasons for allowing knots in various sizes. Several
of the better mills pre-fill the knots to ensure quality.
