Honeycomb Conveyor Belt and Flat Wire Belt

Yes. In this product range, honeycomb belt and flat wire belt describe the same basic construction: formed flat-strip pickets connected by straight cross rods to form an open lattice. Both names are used internationally, with terminology varying by market and supplier.

The strips stand on edge, and their upper edges form the carrying level. “Flat wire” describes the rectangular strip material; it does not mean the wide face of each strip lies horizontally beneath the product. The openings permit air, steam, water and oil to pass through.

PFM Screen uses Honeycomb (Flat Wire) Conveyor Belt for this range. It is a different construction from the lightweight formed-wire belts commonly called flat flex or enrober belts.

• Honeycomb / flat wire belt: Consider it when an even carrying level, open drainage and a relatively rigid lattice suit the product and load. Small or fragile items must bridge the actual openings and transfer gaps.
• balanced spiral woven belt: Consider this where a different mesh density, product-contact pattern or airflow balance is needed. Suitable tightly woven configurations can support smaller products.
• eye link belt: Consider it where modular construction and stable support are needed. Eye link belts can have small or wide gaps, depending on the link and spacer arrangement; they are not limited to large products.

PFM Screen supplies all three types. Compare clear opening, product support, load rating, material, cleaning access, drive and transfer geometry. A flat wire belt is not automatically smoother or better for every delicate product than a round-wire construction.

Available materials include stainless steel 304, stainless steel 316, carbon steel and galvanised steel. The published approximate temperature figures below require confirmation for the selected construction and actual operating conditions:

These figures are not guaranteed maximum continuous-duty temperatures for a loaded belt. Material strength, atmosphere, exposure time, thermal cycling, load, coating and the ratings of sprockets, chains and support components all affect suitability.

304 is commonly considered for suitable food, baking, drying and cooling duties. 316 can be considered for some salt, brine, marinade or acidic environments, but is not resistant to every concentration and temperature. Carbon steel is an option for suitable industrial heating and drying; galvanised steel requires a separate review of coating and process compatibility.

The published low-temperature guide of approximately −80°C applies only to suitably specified stainless assemblies. Blast freezing and cryogenic processes are different duties; provide the actual belt temperature and cooling medium rather than treating −80°C as a universal cryogenic rating.

• Welded edge: Cross rods are retained by welded button or washer ends as specified. Check the rod projection and edge clearances.
• Clinched edge: Rod ends are mechanically bent or crimped without a welded end joint. Availability depends on rod size and belt geometry; it is not automatically the preferred edge for every stainless belt.
• Chain edge: Roller chains along the sides engage matching chain sprockets. This provides positive drive through the chains, but alignment, tension, guides and support still control tracking.

All three arrangements can be reviewed, but they are not necessarily interchangeable on every listed mesh size. Confirm the splicing rod and end-fastening method with the ordered edge. Some joints require forming tools or welding; “no special tools” should not be assumed for every belt.

The published guide is approximately 40–65% open area, depending on the construction. This is not a universal limit for all flat wire belts. Ask for the calculated value for the selected pitch, strip thickness, rod diameter and edge arrangement.

• Baking: Openings allow hot air to reach the underside of products; temperature uniformity depends on the oven and loading.
• Frying: Oil can circulate through and drain from the mesh.
• Washing: Spray liquid can pass through the belt; contact points may still shield parts of a product.
• Cooling and freezing: Openings support through-belt airflow and heat removal, subject to the process conditions.

H CB01 has a 13.7 mm cross-rod pitch and a 14.6 mm nominal lateral pitch. These are repeat dimensions, not clear aperture dimensions. Confirm the actual opening against the smallest product before selecting this specification.

Please provide:

• Material: SS304, SS316, carbon steel, galvanised steel or another grade for review.
• A — overall width: In mm, together with total belt length in m. State whether width includes chain edges, guards or rod ends.
• B — cross-rod pitch: Measure from the centre of the first rod to the centre of the eleventh rod and divide by 10. Repeat in several locations, preferably on an unworn section. Averaging reduces reading error but does not remove wear or elongation.
• C and D: Nominal lateral pitch and cross-rod diameter.
• E × F: Flat-strip height × thickness, in mm.
• G: Number of apertures across the width, plus edge finish and actual clear opening.

Also provide product load, temperature, speed and drive details. A sample section, original drawing or photos with a scale can help identify the belt. Confirm the replacement dimensions and sprocket fit before manufacture.

PFM Screen can review metric and imperial honeycomb / flat wire belt replacements from other manufacturers. Supply cross-rod pitch, lateral pitch, strip height and thickness, rod diameter, aperture count, edge finish, overall width and total length, or provide a sample.

A nominal size alone does not establish interchangeability. Check the actual pitch, edge geometry, sprocket tooth profile, clearances and wear condition of the existing drive. Replacement compatibility should be agreed from a drawing or sample rather than promised as an automatic drop-in fit.

Single-belt replacement and trial enquiries are welcome, including trials on a suitable non-critical line. Confirm availability and any order restrictions for custom material or dimensions with the quotation.

• Order quantity: PFM Screen accepts single-belt replacement or trial enquiries as well as production quantities. Confirm any restrictions for special grades, widths or pitches.
• Standard specifications: The published planning estimate is 2–4 weeks after confirmed order.
• Custom widths, pitches or materials: The published planning estimate is 4–6 weeks.
• Rush orders: Priority scheduling can be requested, subject to material and production availability.

These are planning estimates, not guaranteed dispatch or delivery dates. Confirm the production lead time, drawing approval requirements and shipping time in the quotation. Matching sprockets and spare splicing rods can also be requested.
