GRATEX BELT GRATEX BELT 11 TYPE No. F2, A2 left and right spirals are alternately embedded and connected in a straight-lined rod. A2 with rod pitch less than twice spiral pitch. F2 with rod pitch more than twice. The left-wound and right-wound spirals are alternately arranged and jointed with the straight rods. If the rod pitch is less than two-fold spiral pitch, the belts are called A2. If the rod pitch is equal to or greater than two-fold spiral pitch, the belts are called F2. Feature Advantages ●conveying of unstable product is possible because surface is smooth. The surface is flat, so that unstable items can be carried. ●allowable tension is large and heavy load conveying is possible. The allowable tension is high, so that heavy load can be carried. ●It can be used for high temperature. The belts can be used at high temperature. ●aperture can be made small, so small conveying is possible. The belts can have tight mesh, they can carry small materials.
