Flat-Flex® Conveyor Belt Advantages

The unique design and manufacturing quality of Flat-Flex® belts offer a range of benefits that support operational efficiency, reduce maintenance, and extend service life:

  • Up to 86% open area for improved air and liquid flow
  • Lightweight construction with tension evenly distributed
  • Precise tracking with positive drive design
  • Easy to clean and clean-in-place compatible
  • Supports maintaining product separation during movement
  • Customizable belt width, pitch, and wire diameter

These features help reduce energy usage, improve sanitation, and maintain product integrity across challenging environments and product types.

Proven Open Mesh Performance

Flat-Flex® belts offer a typical open area of up to 86%, creating a smooth carrying surface with good ventilation advantages. This open area improves airflow and drainage, supporting consistent baking, frying, or coating applications such as chocolate coating. The fine workmanship of the wire mesh ensures minimal product sticking, and the belt’s flat surface helps maintain shape, structure, and product separation during transfer.

Smaller diameter transfer rollers and drive components enable tight transfers and reduced product damage. The result is a positively driven, stable system that moves with accuracy, even with complex products or delicate loads.

Stainless Steel Construction Built for Sanitation

The standard stainless steel Flat-Flex® belt is manufactured using 302 stainless steel, offering excellent corrosion resistance and durability in demanding environments. For applications requiring enhanced chemical resistance or higher temperature performance, 316 stainless steel and specialty alloys are also available.

Flat-Flex® belts are designed to withstand repeated washdowns without compromising structural integrity. This makes them especially well-suited for food processing operations where hygiene, reliability, and ease of cleaning are critical to daily production.

Edge Options and Custom Specifications

Flat-Flex® belts are available with several edge loop types to meet safety, hygiene, or mechanical needs. Options include:

  • Single loop edge
  • Double loop edge
  • C-shaped loop edge

These variations help tailor the belt to your process, product, and equipment requirements. Whether you’re working with gear transmission belt systems or need precise alignment with sprockets, our engineering team will ensure each design is optimized to your operation.

Each Flat-Flex® belt is manufactured to custom specifications, including strand count, joint style, belt width, and required support components. We also offer assistance with installation, integration, and ongoing maintenance.
