By dividing the wood into fibers or shells of the wood, it can be seen into several grooves, which absorb less water. or oblique type gives 100% burr surface, while re-saw type is To cut the wood straight and then bring it to the saw to cut the oblique into two oblique sheets. It has a 90% burr surface texture (less due to sawing) and is available in sizes 18″ (150) and 24″ (610) along the length.

Synthetic roofing sheet

The wood is coated on top with pigment or cement. The inorganic fiberglass medium has very good fire resistance (Class A), whereas the wood organic medium has moderate fire resistance (Class C). Synthetic shingle boards have adhesives attached to hold the roof sheet firmly against the foundation sheet to prevent it from being blown off the roof when strong winds strike. especially the roof with a slight slope
