At Ashworth Bros., Inc., we invented the lotension spiral system, and we continue to lead with our industry-leading all-metal and hybrid metal-backbone/plastic-surface belts designed for spiral and turn-curve conveyor systems. Our metal spiral & turn-curve conveyor belts enable you to minimize footprint, maximize throughput and ensure the strength, durability and sanitary performance required in today’s demanding production environments.
Whether you’re processing food, packaging goods, or designing a space-constrained spiral or turn-curve layout, our solutions deliver tight turn radii, proven wear life and hygienic stainless-steel construction.
Omni-Grid® 360 conveyor belts are engineered for rugged spiral and turn-curve applications requiring tight turn ratios and dependable tracking. Designed for continuous operation in food processing and industrial environments, these stainless-steel belts deliver long service life, consistent product flow, and reduced maintenance in compact conveyor footprints.
The Omni-Pro® metal turn-curve conveyor belt is engineered for maximum strength and long service life in high-tension spiral and turn-curve systems. Its patented design provides exceptional wear resistance, making it ideal for heavy loads, high-cycle processing, and harsh operating environments found in freezing, baking, and cooking lines.

FAQs
A turn-curve belt is engineered to navigate a bend or spiral rather than only travel in a straight line. In spiral or turn-curve conveyor systems, the belt must maintain smooth product orientation and handle lateral forces and tighter radii. Utilizing turn curve belting minimizes product transfers. Our turn-curve belts include features like special link geometry, higher tension ratings, and engineered turn-radius capabilities.
The turn ratio indicates the minimum radius of curvature a belt can manage, expressed in relation to the belt width (for example, 1.6× belt width means the inside radius is 1.6 times belt width). Smaller ratios mean tighter turns and a smaller system footprint. For example, our Super Small Radius Omni-Grid belts negotiate down to a 0.8× belt width turn ratio.
We use premium stainless steel (304, 316) or hybrid constructions (metal backbone with plastic surface) depending on the application. Stainless steel is preferred for durability, hygiene, corrosion resistance and high-temperature capability.
Yes. Our metal belts are constructed with burr-free finishes, open link designs for drainage and airflow, and are compatible with rigorous sanitation protocols. Consider our Omni-Grid range for optimal hygienic performance.
Absolutely. Many of our belt families are designed for “easy retrofit to existing systems”. For example, Omni-Grid® 360 Weld is described as “an easy retrofit to existing systems.”
Start by defining your required belt width, product size/weight, conveyor speed, required turn radius (or spiral diameter), load cycles, environment (temperature, wash down, sanitation), and budget. Then consult our engineers or product-specs to choose the belt family and variant that matches those requirements.
Belt life depends on system design, load, speed and maintenance. For example, our Super Small Radius Omni-Grid® offers belts rated at 100,000 cycles in typical use. Regular maintenance, correct tensioning and alignment will extend life considerably.
