Quick answer: table top chain, flat top chain, top plate chain and slat band all mean the same product: a single narrow strand of hinged plastic plates, sold by length in fixed plate widths of 82.6, 114.3 and 152.4 mm. Mat top, plastic mesh belt and modular net belt normally mean the other product: a plastic modular belt assembled from moulded modules on hinge rods, bricked across any width and sold by area. Chain plate is a translated term that can mean either, so it always needs a follow up question.
Is a table top chain the same as a flat top chain?
Yes. They are two names for one product. A table top chain is a single strand of moulded plastic plates joined by pins, running inside a guide track, driven by a toothed wheel at one end. The name comes from bottling and canning lines, where the chain runs at table height and containers slide across from one strand to the next.
Flat top is the same object described by its surface. Whichever word your supplier uses, the specification is identical: a series number, a plate width, a plate material, and a length, with the wheels, wear strips and transfer plates quoted alongside it. Veybelt's 820 series straight running chain is a table top chain, a flat top chain and a top plate chain at the same time.
Is mat top the same as table top?
No, and this is the term that causes the most wrong quotations. Table top describes one narrow strand. Mat top describes a wide plastic mat that behaves as a single surface across the full conveyor width.
In practice, when a buyer says mat top they are describing what the industry more precisely calls a plastic modular belt. It is built from moulded modules threaded onto hinge rods, laid in a brick pattern so the joints stagger across the width. It can be made in almost any width, because width is a build specification rather than a catalogue option. Where a table top chain is quoted per metre of one strand, a mat top is quoted per square metre.
The confusion is understandable, because the two are often used for the same job. A bottling line can carry containers on three parallel table top chain strands, or on one wide modular belt. The buying process is completely different in each case.
Chain or belt: the line that actually matters
| Flat top chain (table top, slat band) | Plastic modular belt (mat top, mesh belt) | |
|---|---|---|
| Construction | One narrow strand of hinged plates on pins | Moulded modules on hinge rods, bricked across the width |
| Width | Fixed plate widths: 82.6 / 114.3 / 152.4 mm | Built to the width you need |
| Sold by | Length, in metres or in links | Area, in square metres |
| Wider conveyor | Run several strands side by side | Build one wider belt |
| Rated by | Chain plate load in newtons, for example 4,300 N on the 820 | Belt strength in N/m of width |
| Repair | Replace a section of the strand | Replace individual modules and a rod |
| Support | Runs in a wear strip track | Runs on wear strips or a slider bed across the width |
Once you know which side of that table you are on, most of the naming noise stops mattering. The plate widths are the fastest tell. If someone quotes you 82.6 mm, you are buying chain. If they ask what width you want, you are buying belt.
Term by term
| Term | What it usually means | Product family |
|---|---|---|
| Flat top chain | Single hinged strand of plastic plates with a flat carrying surface | Chain |
| Table top chain | Exact synonym of flat top chain. Common in bottling and beverage | Chain |
| Top plate chain | Same product again, named after the plate. Common in European sourcing | Chain |
| Slat band, slat top chain | Same family. Slat is the plate. The term is also used for steel versions | Chain |
| Side flexing chain | A flat top chain built to go round bends, with a bevelled underside | Chain |
| Mat top chain | A wide plastic mat across the full conveyor width. In practice a modular belt | Belt, in nearly all cases |
| Modular belt, plastic modular belt | Moulded modules on hinge rods, bricked across any width | Belt |
| Plastic mesh belt, modular net belt | Translated names for a modular belt, usually an open grid version | Belt |
| Chain plate | Literal translation used in Chinese sourcing. Means the plate itself, or the whole chain | Either. Ask which |
The terms that are genuinely different products
Three distinctions are real and worth holding on to.
Straight running against side flexing. Both are flat top chains, and they are not interchangeable. A straight running chain has a flat underside and will bind, ride up or break if you force it round a bend. A side flexing chain has a bevelled underside that lets the plates fan out and needs a guided curve with wear strips on both sides of the bend. Both families are set out in the flat top chain range.
Plastic mesh belt against wire mesh belt. A plastic mesh belt is a modular belt with an open grid surface, moulded in PP, POM or PE. A wire mesh belt is woven or welded steel, used at temperatures where plastic cannot go. Both get called mesh belt in translated enquiries. If the working temperature in the request is above what plastic handles, the buyer almost certainly means the steel one.
Radius belt against straight running belt. Both are modular belts, and the geometry differs. A radius belt has slotted rod holes so the inside edge can collapse in a bend. Series such as the 916 quote an inner turning radius as a multiple of belt width. A straight running belt has round holes and only goes straight, which is the normal case across the straight running modular belt range.
Why the naming is such a mess
Three forces created it. Machine builders named these products after the job they did on their own lines, so bottling produced table top and food processing produced mat top. Translation added a second layer, because the Chinese terms for chain and belt render literally as chain plate and net belt. And buyers inherit whatever word appears on the last purchase order, which may be a machine builder's internal code rather than any belt maker's name.
The practical defence is to stop trading names and start trading geometry. Pitch, plate width or belt width, surface type, and material settle a product. A name on its own settles very little, which is the point of our note on modular belt naming conventions.
What to send if you are not sure which one you have
- One photo of the top surface and one of the underside, taken square on, with a tape measure in the frame.
- The measurement across one plate or module. If it lands near 82.6, 114.3 or 152.4 mm, you have a chain.
- The pitch, measured from the centre of one hinge rod to the centre of the next.
- The total width of the running surface on the machine, and whether it is one strand or several side by side.
- Any code printed on the underside of a plate or module, even if it looks like an internal machine builder's code.
