Spiral Grid Conveyor Belts

Spiral Grid Conveyor Belts

Spiral Grid Belt also named Flexible Rod Conveyor Belt, it is an innovative wire mesh conveyor belt, specially designed for multi-tier spiral conveyors commonly used in the food industry. As a leading wire belt manufacturer, our wire belt factory has developed this high-quality belt to meet the diverse needs of various industries. This unique spiral conveyor belt is engineered with precision using premium stainless steel wires, ensuring excellent durability and resistance to corrosion. The interlocking mesh pattern creates a strong and stable surface, making it an ideal choice for conveying various products. Spiral Wire Belts usually used for frozen food industrial, the surface is smooth for quick and easy cleaning, also can bear heavy pressure and tension, good performance can reach 180 and 360 degree turn.


Spiral Grid Belts are constructed from cross rods with foldable links on each side. To improve product support, the rods can be covered with spiral mesh. Spiral conveyor belts can also be equipped with a link in the center of the belt width to reduce its turning radius , as well as side guards to prevent product spillage. Additionally, it has many other features:

Straight running and curve to 180 and 360 degrees.

•  Available edge including welded, laddered, hook and chain edge.

•  Finish is smooth and burr-free for quick and easy cleaning, maximizing production.

•  High temperature resistance as the stainless steel material can maintain the perfect performance even in the extremely high or low temperature applications.

•  Corrosion and rust resistance as the stainless steel material and galvanized steel have excellent chemical stability.

•  Durable and long service life as the high quality material and rigid structure.

•  Easy to install and replace as the flexible rod conveyor belt is lightweight.
