Wood Flooring Grain & Grading Rules
Every species of wood has its own unique set of "grading rules," which helps to define and categorize the wood's appearance.
At Gate, we primarily work with oak, which has three grades to choose from: rustic, light rustic, and select.
- Rustic grade is the second most popular grade. It's color interruptions and character marks are generally more prominent than the Light Rustic grade for greater contrast and variation.
- Light Rustic grade is generally the most popular grade. It has prominent color interruptions and limited-size knots, wormholes, mineral streaks, and other character marks.
- Select grade has minimal character marks and small color interruptions.
When choosing your wood, you'll also want to consider its cut. The cut used affects the wood floor's appearance and performance. It also determines what width sizes are available for the wood floor.
- Plain Sawn cut wood is the most popular cut today and has a shorter production time compared to the other cuts.
- Quarter Sawn involves cutting the wood into quarters, with the wood's growth rings set at 90 degrees to the surface.
- Rift Sawn wood can have planks with growth rings that are angled around 45 degrees, which makes it hard to get rift sawn wide-plank flooring.
- R&Q Sawn is made from a mixture of rift sawn and quarter sawn cuts. R&Q sawn boards create less wood waste.
- Live Sawn is the latest wood cut trend. It includes a combination of plain sawn, rift sawn, and quarter sawn cuts, making it one of the most versatile cuts for size and grain pattern.
Because wood is hygroscopic, it will shrink or swell depending upon the amount of moisture in the air or ground. This direction of plank movement as it expands or contracts is largely determined by how the growth rings are cut. That's why you'll see plain sawn boards expand and contract across their width, while quarter sawn and rift sawn boards will expand and contract in thickness.
