Belt Mesh Overlay Type

Balanced Weave Mesh

Balanced Weave Mesh

Provides a flat and stable surface. Offers good flexibility and can handle a variety of product shapes and sizes. Well-suited for applications where a smooth and even surface is important.

Unilateral Weave Mesh

Unilateral Weave Mesh

Can be designed for increased strength in a specific direction. Suitable for applications where directional strength or specific performance characteristics are crucial.

Links Availability

Spiral Metal Belt with Standard links

Spiral Metal Belt with Standard links

The most commonly used, stable, reliable and durable links.

Spiral Metal Belt with Guard Edge Links

Spiral Metal Belt with Guard Edge Links

Side guards are attached to the edges of the belt to create a containment area that prevents products from falling off the sides during transport. The height and design of the side guards can vary based on the specific requirements of the application.

Spiral Metal Belt with Edge Drive Links

Spiral Metal Belt with Edge Drive Links

The positive edge drive and cageless design minimize the risk of catastrophic failures, such as belt flipping or misalignment. This enhances the reliability and stability of the conveyor system during operation.

Edge Availability​

Small Radius Flexible Rod Belts with Welded Button Edge

Spiral Metal Belt with Welded Button Edge

Sturdy and durable, it can meet most application scenarios and is extremely cost-effective.

Small Radius Flexible Rod Belts with 360° Welded Edge

Spiral Metal Belt with 360° Welded Edge

In contrast to a conventional bridge weld, the 360° buttonless weld is devoid of surface imperfections and crevices. This enhances hygienic properties by eliminating the potential for bacteria entrapment. Additionally, it offers a greater product load capacity and reduces wear on the caps of spiral system cage bars.

Flexible Rod Conveyor Belts offer several advantages in various industrial applications due to their unique design and features. Here are some key advantages:
