What is OSB?
 

I emailed about a Blazer for sale inquiring about rust. He said the bed had OSB as the foundation. Maybe I am experiencing a "brain fart" and can't remember. Can someone tell me what OSB is?

Oriented strand board.

OSB is a building material similar to plywood, except it is made of wood chip fibers glued together.

ahhh...like MDF for sheathing! chip board......can see we are all working really hard pre-holiday here!
