Choose standard balanced weave when it supports your product well and provides the open space your process needs. Consider double balanced weave when small or delicate products need closer support. Product size and shape guide the mesh choice; loading and operating temperature help determine the wire sizes and material.
Here is a direct comparison to help you decide which construction to discuss with PFM Screen.

The clear opening depends on the pitch and wire diameter in either construction. PFM offers both standard and double balanced versions with crimped or straight cross wires.
Standard Balanced Weave
Double Balanced Weave
Choose Standard Balanced Weave If...
Your product already has enough support
Trays and larger components may sit comfortably on a standard mesh without needing a closer surface. Start with the product's contact points: a baking tray resting on the belt has different support needs from small food pieces resting directly on the wires.
Airflow or drainage is a priority
For cooling, drying, washing or frying, an open standard specification is a useful starting point when it also retains the product. This lets you focus on the flow needed by the process without adding mesh density that the product does not require.
You want to replace a standard belt that worked well
If the old belt suited the process, matching its specification is usually the simplest choice. Send the old drawing or a close-up photo of the mesh and edge. We can help identify the details needed for a replacement.
Applications to consider: tray baking, cooling, washing and general parts conveying, where the selected mesh gives adequate support.
Choose Double Balanced Weave If...
Small or narrow products need closer support
The paired spiral arrangement allows closer spacing across the belt. It is worth considering for small components or food products that need a finer supporting surface than the proposed standard mesh provides.
Products tilt or catch in the existing openings
If a small part tends to tip into the mesh, compare its shape with a closer specification. Double balanced weave offers one way to obtain that closer support. A revised standard mesh may also work; we can compare the two against the product you convey.
Delicate products need more closely spaced contact points
A closer supporting surface may suit products that rest unevenly on a more open mesh. If surface marks matter, a mesh sample is useful for checking the contact pattern with your product.
Applications to consider: conveying small parts or delicate products, including processing lines where close support is needed during heating or cooling. Material and mesh details are selected for that particular process.
What About Heavy Loads, High Temperatures and Cost?
For heavy loads, compare the proposed belt specifications, including wire sizes, cross rods and conveyor support. “Double” describes the spiral arrangement; it does not mean twice the load capacity.
For high-temperature service, select the alloy for the temperature, atmosphere and load. A denser weave alone does not establish a higher operating temperature or guarantee fewer product marks.
If both constructions suit the job, ask us to quote the alternatives against the same belt dimensions and operating conditions. Material, mesh and edge details affect the price. For maintenance planning, we can also confirm the joining method for the proposed belt so you know what replacement or repair will involve.
Let PFM Screen Help You Choose
Tell us what you convey, its approximate size and weight, and the operating temperature if known. A product photo or a photo of the existing belt is a useful starting point; share the weight information you already have, and we can help with any further details.
We can help compare the mesh options and set out a proposed specification for your review. See our Balanced Spiral Woven Conveyor Belts for construction photographs and enquiry forms.
