Adaptable conveyor belts for spiral cage systems
· Collapsible for easy cleaning
· Protects product quality and loss
· Available as rods-only or with a mesh overlay
· Metal Grid belts are our most popular application – adaptable spiral cage systems conveyor belts. They’ve proven themselves in spiral cage system applications throughout the world, running smoothly and dependably year after year.
With their positive conveyor sprocket drive, Metal Grid belts provide a smooth, continuous product flow that is gentle with fragile or delicate products. They save money by protecting product quality and reducing waste.
Fully collapsible for easy cleaning, C Metal Grid belts are available in standard (2.2) radius, reduced (1.7) radius, and tight (1.1) radius designs. It can be manufactured with a double pitch overlay, or with plastic filler rods or strips for supporting extremely small products.
Rods-Only Construction
A rods-only construction provides maximum air circulation, making these Metal Grid belts ideal for cookers, proofers and freezers in bakeries. They are also suitable for other applications such as freezing of larger cuts of meat and poultry, and products in trays or packages where minimal product support is required.
Mesh Overlay
When product support or smaller openings are needed, a balanced weave mesh overlay to the conveyor belt is added. Flexibility is maintained, while adapting the Metal Grid belts for a particular application such as freezing soft dough products, beef patties, fish sticks, and other prepared products.

Standard Radius Spiral Cage Belts
The turning radius of a Metal Grid belt is determined by the ability of the links to nest on the inside edge of the turn and by the width of the metal conveyor belt. Since the slot length determines the amount of nesting and is a fixed dimension, the minimum turning radius becomes a factor of belt width. For a standard radius Metal Grid belt, the nominal inside belt radius is 2.2 x the belt width.
