This is triaxial cloth which can be thought of as a double bias cloth combined with a uniaxial cloth. It is a warp triaxial which means that the uniaxial threads run along the length of the roll. It is 0.8mm thick and it has 283 gsm of uniaxial threads running along the length of the roll plus 230 gsm in each of the bias directions. A full roll is 52 metres long. It is 1.27m wide so it cannot go through the post unless it is folded.
