The Job Telescopic Fence Fabrication Has to Do
Telescopic fences and adjustable barrier systems provide flexible livestock containment that can be extended, retracted, or reconfigured as needed. These systems are valuable for temporary holding areas, variable-width races, and adaptable pen configurations. At Fulei Metal, we fabricate telescopic fence systems for livestock operations across Europe and Australia.
Telescopic Fence Applications
Adjustable race systems use telescopic panels allowing race width adjustment without disassembly. Temporary holding pens use telescopic connectors for quick assembly at various angles. Variable-width gateways use telescopic gate panels that extend or retract to fill openings of various widths. Crowd gate systems use telescopic or sliding mechanisms to move animals forward through races. Show and auction equipment uses telescopic panels that are lightweight but strong for portability.
Decisions to Make Before Cutting Telescopic Fence Fabrication
The telescopic extension mechanism must operate smoothly in dirty, outdoor environments with appropriate clearances and sealed bearings. Panels must maintain structural strength at full extension with appropriate overlap length. Locking mechanisms must lock positively at each extension position using spring-loaded pins, cam locks, or lever-operated latches. Telescopic mechanisms are vulnerable to corrosion, requiring galvanized steel with anti-seize compound on sliding surfaces. Systems must not have pinch points or protruding hardware that could injure animals.
What Material Suits Telescopic Fence Fabrication
Hot-dip galvanized steel is the standard material with zinc coating providing corrosion resistance. Powder coating over galvanizing provides additional protection and smoother sliding surfaces. For telescopic mechanisms requiring smooth, corrosion-free sliding, stainless steel components resist corrosion and galling.
Cutting, Bending and Welding Telescopic Fence Fabrication
Our TRUMPF fiber laser cuts telescopic mechanism components, locking plates, and mounting brackets with dimensional accuracy directly affecting sliding operation. Steel tubes are precisely dimensioned for telescopic sections with appropriate clearance. CNC tube bending creates consistent bends in inner and outer sections. Component assembly uses MIG welding with care to avoid weld spatter on sliding surfaces. Telescopic components are hot-dip galvanized, with sliding surfaces receiving anti-seize compound.
Our assembly team assembles telescopic sections, installs locking mechanisms, and verifies smooth operation throughout the full extension range. Each unit undergoes functional testing including extension, retraction, and locking engagement.
Adjustable Fencing: Tolerance After Galvanizing
An adjustable fence adds a tolerance problem to a normal panel: the sliding or pinning elements have to work after galvanizing, and galvanizing adds thickness to every surface it touches. A pin that fits a hole comfortably in bare steel will not enter the same hole once both parts are coated. That is why the holes in adjustable assemblies are either cut oversize to a coating allowance or drilled after galvanizing and treated at the cut. Slots, where they are used, are checked for full travel on a galvanized sample rather than on the first bare part off the line.
Closing Notes on Telescopic Fence Fabrication
Telescopic fence fabrication requires precision manufacturing, understanding of sliding mechanism design, and corrosion protection expertise. Fulei Metal’s experience in livestock equipment fabrication makes us a trusted partner for telescopic fence projects.
Fulei Metal builds components like this in-house. The DFM engineering review page explains how the process is set up and checked, while custom sheet metal fabrication covers the materials and finishes we normally run. Related reading: Cattle Fence Panel Fabrication.
What a Telescopic Fence Drawing Has to Get Right
A telescopic or extendable livestock fence is a sliding mechanism before it is a barrier, and the drawings that come to us usually specify the barrier and leave the mechanism. The items that decide whether it works are the section fit, the travel length, and the stop. Section fit: the inner section has to slide inside the outer one without enough clearance to rack when it is extended, and that is a tolerance call-out rather than a nominal size. Travel: how far it extends, which sets the length of each section and the overlap at full extension. Stop: what prevents the inner section coming out, which needs to be a designed feature rather than a bolt added later.
Overlap at full extension is the dimension most often missed. A fence extended to its maximum with too little overlap will bend at the joint under animal pressure, and the bend is permanent. Give us the extended length and the load case if you have one; if not, we will state the overlap we recommend and you can confirm it.
Can you build to our existing fence drawings?
Yes. Send the drawings with the extended and closed lengths, the section sizes and the galvanizing note, and we will flag anything that will rack, will bind, or has no positive stop.
Do you supply the latch or the gate hardware?
Hardware can be supplied to match or bought to your specification — tell us which on the enquiry. Pen layout and animal handling practice are yours or your supplier’s; we fabricate the metal components to the drawings.
Sliding Fit, Coating and What Binds After a Season
The reason a telescopic fence stops working is almost never wear — it is coating build-up and corrosion in the sliding fit. Hot-dip galvanizing adds thickness to both sections, and if the clearance is specified on the bare steel dimensions, the coated parts will not slide. The clearance has to be specified after coating, and that is a drawing note worth stating explicitly.
The second cause is corrosion in the overlap. Water sits between the sections, and a galvanized surface in a wet, salty, manure-laden environment will still eventually bind if the fit is tight and there is no drainage. A drain path at the low end of the outer section, and a specified clearance that tolerates some surface build-up, keep a fence serviceable for years rather than seasons.
Inspection follows the buyer drawing and the approved sample, with general tolerances to ISO 2768 unless stated. Sliding fit is checked on a sample from each batch by extending and retracting the assembly, and coating thickness is recorded. Material and coating documentation is issued per order — see material certification and traceability. Sections are bundled with separation; for export consignments see export packaging standards.
Need a Similar Part?
Most enquiries that start on a page like this are not an order for Telescopic Fence Fabrication — 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.
