  1. Id much prefer Pu conveyors over cotton and dont mind paying extra as its worth it in the long run

  2. I'm currently studying and researching conveyors garment conveyors, belt conveyors and floor conveyors right now and this really helped me. Thanks for sharing!

  3. But are Pu conveyors really what they are cracked up to be or are they a waste of money. I'm not convinced.
