I bought 20 OSB3 T&G boards delivered on a palette in heavy rain and on unwrapping found that 3 had been slightly damaged. It looked like a fork lift or similar had broken a 4-5 cm area on the long sides of the board in two places into the groove. Since I was cutting shapes into the boards to fit an irregular sized roof it wasn't a problem but I did expect the boards to be as advertised.
