Pine Rough Clear Grade 50 x 152 6.600m refers to a piece of pine lumber that is rough-sawn on all sides, indicating that it has not been planed or smoothed. “Clear grade” means that the wood is of high quality and is free from knots and other defects that could affect its strength or appearance.

The measurements provided indicate that the piece of lumber is 50 millimetres thick, 152 millimetres wide, and 6.6 metres long. Pine lumber is commonly used in construction projects for framing, decking, and various structural applications due to its strength, workability, and affordability.

It’s worth noting that rough-sawn lumber typically requires additional processing, such as planing or sanding, before it can be used for finished applications. The rough surface can also make it more difficult to accurately measure and cut the lumber to the desired length or shape.
