How This Cattle Fence Panel (Heavy-Duty) Is Fabricated and Checked
A heavy-duty cattle panel is a simple product with one hard requirement: it has to stay rigid and corrosion-free in a wet, abrasive environment for a decade. Both are decided before the panel is dipped in zinc.
| Stage | What happens | What is verified before the job moves on |
|---|---|---|
| Tube cutting | 42 mm tube cut to length on the tube laser, with the ends prepared for welding | Cut length and end squareness on the first frame. A panel is a set of parallel members, so a length error shows up as a diagonal rather than as a short member |
| Bending and end preparation | Any bends formed, and every tube end closed or capped before galvanising | That no tube is left with an open end. An open tube takes the galvanising bath in and does not let it drain |
| Drain and vent provision | Holes drilled into closed sections so air and zinc can move through during dipping | Hole size and position on every closed member. A closed tube without drain holes holds acid and zinc, and corrodes from the inside out within a season |
| Frame welding and squaring | Frame MIG welded with the rail spacing held in a fixture | Diagonals and overall size, measured before galvanising and again after, because the bath heat moves thin sections |
| Hot-dip galvanising | The panel is dipped, drained and cooled | Zinc thickness against the specified figure, and the drain condition. Zinc can bridge a narrow gap between two members if the design does not allow it to escape |
| Post-galvanising check | Threads re-tapped where used, and any zinc spikes or runs removed | Thread condition, and the absence of sharp zinc runs that would catch on an animal or a handler |
| Packing | Panels stacked with spacers between them for transport | That panels are not stacked wet. Wet-stacked galvanised steel forms white rust in transit, and that is a claim waiting to happen |
Adjusting Cattle Fence Panel (Heavy Duty) Without New Tooling
A fence panel is specified by its span and its infill. Almost everything else follows.
| What can be changed | What it affects | What it does not affect |
|---|---|---|
| Height, length and rail spacing | Tube lengths, rail count and the packing | The tube diameter and wall thickness |
| Tube diameter and wall | Rigidity against a rubbing animal, and the weight the installer handles | The galvanising process |
| Infill: horizontal bars, mesh or sheet | What the panel keeps in or out, and how much an animal can lean on it | The frame |
| Joining to the next panel or the post | Whether the run is bolted or pinned, and how it is aligned on site | The panel geometry |
| Finish: galvanised, or a colour applied over the galvanising | Appearance against the life of the coating | Nothing structural |
| Bundling and packing | How the panels are handled and stored on site | The panel itself |
Questions Buyers Ask About Cattle Fence Panel (Heavy Duty)
Why do the tubes need holes drilled in them?
Because hot-dip galvanising means dipping the whole part in molten zinc, and a closed section has to let air out and zinc in and back out again. Without drain and vent holes the inside of the tube is never coated and holds the acid from the pre-treatment, so the tube rusts from the inside while the outside still looks new.
The finished panel is not exactly the drawing size – why?
Because galvanising adds zinc on every surface, and the bath temperature can move a thin section while it is hot. Overall dimensions are quoted with that in mind, and where a dimension has to be exact – a bolt hole, a hinge pin – it is either masked, re-machined after dipping, or moved to a part that is not dipped.
Can the panels be supplied in a colour?
Yes, as a powder coating applied over the galvanising. It is worth being clear about what each layer does: the galvanising is what protects the steel and cannot be repaired on site, and the coating is what gives the colour and takes the damage. Where a colour is required, the answer is coating over galvanising rather than instead of it.
Drain holes and the dipping allowance are what separate a panel that lasts from one that rusts from inside. Send the run length and the post centres through the RFQ form and the panel and its fixings are sized to them. Related: tube and frame welding, surface finishing and export packaging.
Reinforced Rails Are a Span Decision, Not a Thickness Decision
A heavy-duty cattle panel is usually specified by tube diameter and wall thickness, and those numbers are the least interesting part of it. What decides whether a panel survives cattle leaning on it is the span between posts and the section of the top and bottom rails, because those two rails are what take the bending. Adding wall thickness helps, but making the rail deeper helps more and adds less weight to a panel that somebody has to carry and erect by hand.
- 2.1 m wide is a handling dimension. A panel wider than that gets awkward for one person and starts needing two, which is a real cost on a long fence line.
- The vertical members are what keep the rails apart and stop the panel racking. They are lightly loaded compared with the rails, and they are where most drawings over-specify.
- Modular means interchangeable. A panel that is nominally the same size but not actually interchangeable is a fence that cannot be repaired with a spare, and that is a straightness and hole-pattern question rather than a strength one.
Galvanizing a Long Thin Panel Without Turning It Into a Banana
A welded panel this size goes into a zinc bath at roughly 450 degrees and comes out having been heated and cooled as an assembly, which lets the residual stress from welding rearrange itself. Long, thin members are the worst case: a panel that is flat on the bench can come out of the bath with a bow. Hollow sections also have to be vented, or trapped air expands in the bath and the section can be damaged, and they have to drain, or zinc stays inside.
Vent and drain holes need to be placed where they do their job and where an animal cannot catch on them – which is a drawing instruction, not a shop-floor decision. Panels are jigged for dipping and checked afterwards. If your panels need to be interchangeable between bays, tell us at quote stage, because flatness has to be specified and held rather than assumed. Lead time is quoted after drawing review and process confirmation.

Questions buyers ask before sending drawings
The questions that come up most often before a project starts, answered the way we answer them by email.
What do you need from me to quote Cattle Fence Panel (Heavy-Duty)?
2D drawings as PDF, DWG or DXF, or 3D files as STEP, IGES or SolidWorks, together with material grade, sheet thickness, surface finish, quantity and destination country. If the drawing is not finished yet, send a photo, a sketch or the existing part instead — we review what can be measured from it and reply with the questions that still need answering.
How long does a quotation take?
Enquiries are answered within one business day. Simple laser-cut and bent parts are quoted within 24 hours. Welded frames, assembled units and multi-part structures are quoted after the drawing review and process confirmation, and the date is confirmed in our reply.
Is there a minimum order quantity?
Prototypes are made from a single piece and small batches of 10–50 pieces are routine. Prototype, first batch and repeat volume are quoted together so the numbers stay consistent as the project scales.
Can you work from a sample or a photo if I have no drawing?
Yes. Send the part itself, clear photographs with a rule or caliper in frame, or a dimensioned sketch. We measure what can be measured, list what is still undefined, and confirm it with you before production.
Need a Similar Part?
Most enquiries that start on a page like this are not an order for Cattle Fence Panel (Heavy-Duty) — they are a search for a factory that can make something like it. Send us your drawing, 3D model or sample and we will review the manufacturing process and the quotation requirements, then come back with a process plan, a price and a lead time.
We work from 2D drawings, STEP / DWG / DXF / PDF files, or a physical sample if that is all you have.
