The Grade
Discovering Inspiration at Every Step
When wood is lumbered, it is classified into four appearance categories, commonly known as 'grades.'
These grades do not indicate the wood’s quality but rather its visual characteristics.
The available grades for wood flooring are Prime, Select, Nature, and Rustic.
Rustic Grade

Rustic grade remains a popular choice for engineered wood flooring for several reasons. Its visual charm, affordability, and distinct character make it especially appealing.

These unique characteristics create a warm and inviting atmosphere, making it an excellent option for those looking to add a cozy, organic touch to their interiors.
