How to attach stainless wire mesh so it doesn't fray?

Hey all, I’m working on the trommel I was talking about in this other thread.



I now need to figure out the best way to attach stainless wire mesh so that it won’t fray over time. A couple hundred pounds of sawdust will be rolling around inside the machine, and at some points I can’t avoid the mesh needing to have holes to allow the support spars to connect through to hold the outer layer of screen. Obviously, I’m not going to put holes in it where I don’t have to – but the dual chambered nature of the machine means that the inner layer of mesh has to have some holes in it.

I’m worried though, about the mesh fraying over time like cloth would.

So first, is this an issue I need to be worried about? The mesh will be pinned between a traversing piece of angle iron and a radial hoop of flat bar. Doesn’t it seem like, over time, the wire mesh will fray? Or perhaps the stiffness of the stainless wire threads (60 mesh and 30 mesh) will mean that won’t be a problem like it would with cloth?

Second, what can I do to minimize the effect? I need 14mm holes in it for the spars to pass. I was planning to punch the holes on a bench punch, figuring that’d be the cleanest cut I can make. Would it be worth trying to braze around the hole after (or maybe before?) I make it – kind of like paper hole protector rings you use in a binder? Or, I was also wondering about using an external tooth lock washer against the mesh, figuring its teeth might kind of grab on to the wires and spread the pulling load, so it’s not as easy for individual wires to fray.
Or another idea – could I use my cnc plasma to cut the holes, assuming that the cut is going to fuse the ends of the wires together? (Perhaps with a sacrificial backing piece of stainless sheet metal?)

I looked around online for ideas on best practices for affixing wire mesh cloth, but most of what I found was for much bigger, heavier cloth where you can put a bolt through the (much larger than mine) holes that are already in the mesh. An approach that doesn't disturb the mesh might be a worthwhile "thought experiment".

Make the spars in two parts, 'top' and 'bottom'. Bottom spar holds inner mesh, top spar holds outer mesh. Spars are hollow, stacked, and set diametrically opposed to the pair on the other side, as needed. Spars have spikes on, say, 2" washers/plates, that 'mesh with the mesh' it's supporting. (Bigger washers=more stable spar.) (Spikes go into recesses of mating washer/plate, so it fully penetrates and locates mesh without cutting any wires.) To secure everything, run wire cable completely thru spars on one side, mesh x2, center member, spars and mesh on other side of 'diametrically opposed spars' and out the other side. Next, tension cable so spars support mesh appropriately. Number of spar locations, cable tension, cable diameter, and even number of cables within each spar are user-adjustable variables to give the support required while minimizing mesh disturbance. You might need to use a 'needle' to thread the cable, and you might need to bend the mesh to enlarge an existing hole for the cable to pass thru, but hopefully without wholesale cutting of mesh 'fibers', reducing the possibility a fraying quite a bit. The spikes in the washers will help locate mesh even if a few fibers are cut when penetrating mesh with needle/cable.

Or just weld the damn thing. As dgfoster said, try to keep the flame away from the relatively thin mesh. In my opinion not so much to keep it from melting but more to keep the SS from oxidizing or whatever it does when it gets too hot. I have silver soldered quite a bit of SS and if you overheat it, the solder will not stick. I'm not sure if it is in fact an oxidation issue but something very squirrely happens to the SS and nothing will stick to it unless you grind it down and start over.

I don’t think that overheating issue is limited to stainless. I’ve done it to just about everything—-certainly lots of alloy steels, copper, bronze,etc. I (perhaps incorrectly) attributed it to burning away the flux. Once the surface is oxidized no amount of additional flux will allow flow of solder. As you said, clean back to bright metal and don’t be so ham-fisted next time! ;-)

Manufacturing Process of Metal Mesh

Steel is created from iron and has distinct and desired qualities. Particularly, stainless steel is completely rust-resistant and incredibly robust, making it the perfect option for many economic applications. In addition, due to their superior ductile quality—the capacity to be shaped into wires—and their tensile strength and flexibility, steel wires are more advantageous for producing wire mesh and other products.

With competitive price and timely delivery, Yubang sincerely hope to be your supplier and partner.

Wire mesh is one of the earliest and most basic items manufactured from steel. Steel wire mesh has been used for thousands of years in various forms. However, the ever-growing social economies of the world have found new uses for objects like fencing and barricades, safety covers for working machinery, cages, grills, sifters, and shelves. Concrete reinforcement made of iron welded wire mesh fulfils another important function. Businesses that produce steel wire serve secondary-level ancillaries that use these wires to weld or weave mesh.

Types of Metal Mesh

Woven Wire Mesh

In woven wire mesh, the arrangement of intersecting wires resembles the weave of a fabric. The wires are typically woven over and beneath the parallel wires to form a strong sheet. “Plain Weave Mesh” is another name for woven wire mesh. A "Twill Weave" might be used when a more flexible sheet is required. This entails weaving wire below the first pair of parallel wires, over the second pair, and so on.

They are instead fed into a contraption that resembles a loom, weaving a straight wire over the design of the user's choice. After the wires have been bent oppositely, the following straight wire is passed through the pattern. The machine repeats this process until the correct dimensions are obtained, at which point the completed wire mesh sheet is cut to the requisite size.

Welded Wire Mesh

Using accurate, semi-automatic welding equipment, steel welded wire mesh is produced. This machine features a chamber that can give welds at expected intersections, which in the case of a mesh, are the locations where steel wires aligned horizontally and vertically cross.

After feeding one parallel alignment of stainless steel welding wire into the machine, another parallel alignment of wires perpendicular to the first is fed in. The machine then joins the two wires' 90-degree intersection by welding.

Wire Mesh Welding Machine

To construct the weld, heat is generated by electrical resistance. Following the completion of the welding, another length of the parallel wires is put into the device to carry out additional welding. Once the specified length of welded mesh has been formed, and the mesh has been cut to the necessary dimensions, the procedure is terminated.

In order to mechanically position the wires, they are fed from spools levelled crosswise, with cut wires placed out evenly. During mesh welding, the wires are perpendicular and at right angles to one another. The programmed welding procedure starts once the wires are in place and create a consistent weld at each cross-section.

The last processes involve rolling the welded wire mesh up like in wire weaving or cutting it into the right-sized sheets that may be stacked in rows to make wire mesh panels. Only larger wires that can endure the welding process can create a welded mesh, which is heavier, more robust, and stronger than woven wire mesh.

Vinyl Wire Mesh

Applying a vinyl coating to welded or woven wire mesh creates a strong barrier for very flexible wire mesh. Vinyl-coated wire mesh is stable over a broad temperature range and resistant to impacts, scratches, and abrasions. Due to the vinyl covering that makes the wire mesh appear composed of plastic, wire mesh is sometimes referred to as a plastic mesh. Wire mesh that has been vinyl-coated is strong, durable, immune to rust and corrosion, and has a nice appearance. The wire is also shielded from harmful elements like water.

Galvanized Wire Mesh

The raw or carbon steel wire used to make galvanized wire mesh is coated with zinc during the galvanizing process. The zinc layer is a barrier to keep the wire mesh from corroding and rusting. Galvanized wire mesh can be made using either galvanized wire or plain steel wire woven, welded, and then galvanized. Galvanizing the metal after it’s been produced increases its quality, but it is more expensive than the other two methods.

Window guards, infill panels, greenhouse fencing, agricultural and gardening fencing, building and construction fencing, and security fencing are all excellent uses for galvanized wire mesh. Due to its affordability, it is one of the most popular types of wire mesh.
