A panel run gets bought for the day it goes up and judged on the day it comes down. That is the part nobody prices. A collection buys forty frames for a holding yard, runs them two seasons, then needs the same steel three hundred meters away for an intake bay.
If the joints were welded on site, the posts went into concrete and nobody wrote a number on a frame, those panels are scrap with a delivery receipt. If the run was built to come apart, the same steel does the next job. Wire cage panels sell on durability, and durability is the easy half — the half that decides whether you buy them once or four times is whether the run can be taken down, stacked flat and rebuilt by people who were not there the first time.
Executive Summary
A demountable run rests on four decisions made before the first order: a joint that repeats, a footing that releases, a module that divides the perimeter, and a marking system that survives a winter in a container. Get all four right and a set of wire cage panels moves between paddocks, intake bays and seasonal pens for a decade.
Get one wrong and the panels become a permanent fence at permanent-fence cost. That is not a figure of speech; it is what happens when the only tool left is a grinder.
What follows covers module arithmetic, footing options and what each gives back, stack and lift limits, the joints that open under animal pressure, and the checklist that keeps a rebuild possible. Every decision here is cheap at the order stage and expensive afterward.
Quick Answer
Wire cage panels stay reusable when four things are specified together: a joint that repeats without adjustment, a footing that releases without demolition, a module that divides the perimeter, and a number on every frame. Miss any one and the run turns into a permanent fence the first time it goes up.
Key Takeaways
- A panel run is worth what it is worth on the day it comes down, not the day it goes up.
- Module count decides whether the perimeter closes on a full panel or a cut one.
- Cast sockets and base plates give the steel back; driven stakes usually do not.
- Stack flat, number every frame, and keep the bottom panel off the ground.
- Joints open under animal pressure well before the mesh itself fails.
Why the Run Is Judged on the Day It Comes Down
A permanent fence and a demountable run use the same mesh. They differ in four details that cost almost nothing at the order stage and a full rebuild later.
The four conditions
A joint that repeats comes first. A bolted clamp with a fixed hole pattern returns to the same position every time. A welded splice or a field-drilled hole does not, because the second assembly never lands where the first one did.
A footing that releases comes second. Anything cast around the upright is permanent by definition. Anything the upright sits inside, or bolts down onto, can be given back.
A module that divides the perimeter comes third. A run that closes on a full panel rebuilds anywhere. A run that closes on a cut panel rebuilds only on that exact footprint.
Identification comes last, and it is the cheapest. Someone sorts a frame with no number by trial and error on a cold morning. Panels stop being interchangeable once a crew cuts, drills or fits one to a corner.
Buyers pick the animal fence mesh on aperture and gauge. These four details decide the run’s second life.
Counting Panels Before You Design Anything
Panel count for a pen perimeter is arithmetic, not estimation. Measure the perimeter, subtract the gate openings and divide by the module.
A 40 m perimeter with two 3 m gates leaves 34 m of barrier. At a 2.5 m module that is 13.6 panels, which is not a number anyone can order.
Round down to 13 and you have 32.5 m against 34 m of gap. Round up to 14 and you carry 35 m into it, so someone cuts a panel or forces a joint open.
The honest answer is 13 full panels plus a purpose-made filler. That filler is the odd panel at the end of a run, and it belongs in the first delivery rather than a discovery on site. Cut one from a standard frame and it loses its edge treatment and its second takedown.
When the perimeter will not divide
Most real perimeters do not divide. Corners, gate returns, a tree that predates the project and a building line all eat into the module.
Fix the panel count first and let the filler absorb the remainder. Decide the module from the lift limit and the ground, then size one filler to the actual gap. Writing it into the order keeps every other panel standard, and standard panels are the ones that move.
The modular panel specification follows the same logic: you choose the module once and derive everything else from it.
Footings Decide Whether You Get the Steel Back
The footing is the most common reason a run cannot be moved. A post set in a concrete collar is a post you will cut out, and a cut upright no longer matches its neighbours.
| Footing | Ground it suits | How it releases | Reuse after removal |
| Cast socket | Firm soil, long stay | Lift out, cap the hole | Full, if kept clear |
| Base plate | Slab or hardstanding | Unbolt four anchors | Full, new anchors |
| Driven stake | Soft ground, one season | Pull with a lever | Tips deform |
| Ballast foot | Roof or deck | Lift the weight off | Full, no damage |
Ground socket versus surface base plate
A cast socket gives the stiffest connection and the cleanest rebuild, because the upright returns to a fixed position in a fixed sleeve. Its weakness is the empty socket, which becomes a trip hazard and a water trap. Cap it.
A base plate releases faster and leaves nothing in the ground. It needs a slab or sound hardstanding, and it spreads load into four anchors rather than a buried sleeve. On a run that moves twice a year, it wins.
Neither option tolerates a panel run on uneven ground without help. A 20 mm fall across a 2.5 m module is enough to lift one corner of a rigid frame off its bearing.
Set plates to a string line and pack the low corners with a stainless spacer instead of cranking the anchors down. The load path into the ground runs through this detail, and crews leave it to whoever arrives first.
Stack, Lift and the Weight Nobody Plans For
A demountable run spends more of its life stacked than standing. That changes what matters at the order stage.
Start with the two person lift weight for a panel. A 2.5 m by 2 m frame in 3 mm wire with a perimeter tube lands between 35 and 55 kg. Two people carry that across flat ground, not across a muddy paddock in wind.
If the crew moves the run by hand, the lift sets the module, not the drawing.
Stack height follows from the frame. Flat-stacked panels bear on their frames, not their mesh, so the mesh stays safe.
What fails is the bottom frame, which carries the whole stack and sits in whatever water the ground holds. A storage rack for spare panels that keeps the lowest frame 150 mm clear solves most of it.
The panel stack height when stored flat is a structural question, not a space question. Six to eight frames is a working stack. Beyond that the bottom frame takes a permanent set.
Number every frame before the first installation. Paint it on the frame, not on a tag, because tags come off. That is the whole of labelling panels so a run rebuilds in order.
Storage is also where a run starts to corrode. Water sits between stacked frames, and the cut end and the ground line take the worst of it. A rack that drains beats a rack that shelters.
The Joints That Open Under Load
Mesh rarely fails first. Joints do. An animal that leans, rubs or charges puts its load into the connection between panels, and that connection is the only part of the run designed by whoever assembled it.
A panel that opens under animal pressure shows it three ways. The clamp rotates on the tube. The bolt loosens and the frames separate by a few millimeters.
The upright rotates in its footing, which opens every joint along that bay.
The fix is bracing, not a heavier clamp. A diagonal in the end bay, or a corner brace tying two panels into a rigid corner, takes the racking load out of the joints and puts it into the ground. Frames that rack open their fixings no matter how tight those fixings are.
Choose fixings for repeated assembly as well as strength. A reusable panel fixing that survives repeated assembly needs a captured nut or a threaded insert, so the crew does not cut a fresh thread into thin tube every season.
Panel-to-frame connections follow the same rules as any mesh-to-frame fixing: a fixing that comes undone without damaging either part beats one that cannot.
Rebuilding the Run Somewhere Else
The rebuild tests all four conditions at once.
Relocating a panel run to a new paddock means a different perimeter, a different slope and probably a different gate position. If the module divided the old perimeter, it may not divide the new one, so the filler travels with the run.
Site the new run before lifting anything. Set the corners, check the diagonals, and confirm the footprint closes on full panels plus the filler. A run set out by eye ends up re-erecting a run out of square, and that run cannot close its last joint without forcing it.
Crews skip ground preparation more than any other step. Strip the line, level the bearing points, and set the curb to a string. On soft ground, a shallow curb of compacted stone under each upright stops uneven sinking.
Two run types move most often. A demountable panel run for a quarantine pen moves because intake needs change with the season. A temporary holding pen for hoofstock moves because grazing rotation moves, and the pen follows.
The seasonal case is the clearest test. A seasonal pen that comes down each autumn and goes back up in spring will last about a decade if the footings release and the frames are numbered. The same pen with cast-in posts lasts one season.
Inspectors ask about bracing and fixings first, and the welfare and inspection guidance published by the national zoo associations assumes that record already exists.
The Order Checklist
Work through this before the purchase order goes out. Each line is cheap now and expensive later.
- Measure the perimeter and subtract every gate and service opening.
- Choose the module from the lift limit and the ground, then hold it.
- Count full panels, and specify one filler for the remainder.
- Pick a footing that releases, and cap every socket.
- Confirm the joint hardware bolts with captured threads, not field-drilled holes.
- Add a diagonal brace to each end bay and each corner.
- Number every frame and keep the numbering drawing with the run.
- Order the storage rack with the panels, not after the first winter.
A run specified this way costs a little more at the order stage and considerably less at the second installation. The mesh field is the part that lasts. The parts around it decide whether it lasts in more than one place.
For runs built to a non-standard module, custom panel fabrication keeps the filler and the standard panels in the same gauge and finish. A filler in a different gauge will not take the same clamp.
FAQ
Yes, if the footings release and the joints bolt rather than weld. Cast sockets, base plates and ballast feet give the steel back. Concrete-encased posts do not.
Divide the barrier length, after subtracting gates, by the module. Round down to full panels and order one filler for the remainder. That keeps every other panel standard.
Around 50 kg is the practical ceiling on flat, firm ground, which usually means a 2.5 m by 2 m frame in 3 mm wire. Across soft ground or in wind, reduce the module.
Racking, not vibration. A run without diagonal bracing moves as a parallelogram under animal load, and that works every clamp loose. Brace the end bays first.
Six to eight frames on a rack that keeps the bottom frame clear of the ground. Beyond that the lowest frame takes a permanent set.
