The A/B grade panels are seen as the highest quality. Both sides of the panel (A and B) can be used for visible surfaces. The panels show minor to no defects and have consistent colour and grain patterns.
The B/C grade panels have one side adequate (B) for visible surfaces and the other side (C) shows several defects or irregularities. The B side is typically smoother and with fewer imperfections than the C side. The B/C panels are used when only one side is visible and the other is concealed or its appearance isn’t essential.
Rustic-grade panels have a natural and unique appearance. They show prominent knots, colour variations, mineral streaks, and several imperfections. Customers appreciate the rustic-grade panels for their appearance. Therefore, they are used where a rugged or traditional appearance is desired.
