Discover how custom sheep gates are designed and fabricated for flock management. Learn about material selection, hinge systems, and galvanizing for long service life in pasture environments.
Introduction
Sheep farming requires specialized gating systems for flock management, drenching, drafting, and loading. Sheep gates must be appropriately sized for sheep, sturdy enough to withstand flock pressure, and designed for easy operation by a single shepherd. At Fulei Metal, we fabricate sheep gates and handling equipment for livestock farms across Europe, Australia, and New Zealand.
Sheep Gate Design
Standard sheep gate heights range from 900 to 1,200 mm. Vertical bar spacing must prevent sheep from getting their heads stuck, typically 100 to 150 mm for adults and 75 to 100 mm for lambs. Drafting gates allow shepherds to sort sheep into different pens with adjustable diverter mechanisms operated with one hand. Self-closing gates in race systems use weighted or spring-return hinges that close automatically after each sheep passes. Race and crush gates control sheep movement through handling systems, with crush gates holding individual sheep for drenching or inspection.
Material Selection
Galvanized steel is the standard material with zinc coating providing corrosion resistance in pasture environments. We use 1.5 to 2.5 mm thick steel tube, with heavier construction for crush gates. For enhanced appearance, powder coating over galvanized steel is available in green and other colors.
Hinge and Latch Systems
Sheep gate hinges must support gate weight while allowing smooth operation, fabricated from steel or stainless steel with replaceable pins. Gate latches must secure gates against sheep pressure while allowing easy one-handed operation, including slam latches, drop-bar latches, and chain-and-snap latches.
Fabrication Process
Our TRUMPF fiber laser cuts hinge brackets, latch components, and reinforcement plates. Steel tubes are cut to length and notched for tube-to-tube joints with accurate notching for full-penetration welds. Some sheep gate designs incorporate curved tube components created on CNC tube bending equipment. Gate assembly uses MIG welding, with all welds ground smooth. Welded assemblies are hot-dip galvanized after fabrication, with powder-coated finishes available.
Case Study: Sheep Handling Gates for a US Producer
Fulei Metal has been supplying a large US livestock operation since 2016, with around 10,000 galvanized fencing, penning and handling parts a year. Sheep gates in that kind of programme are usually the most demanding pieces in the range because they have to be light enough to swing easily and stiff enough not to sag. The section choice follows from that: a lighter tube with a deeper forming rather than a heavier flat bar. Bar spacing is set as a clear opening, not as a centre-to-centre figure, because a lamb can push its head through a gap that looks closed on a drawing. Gates are checked on a flat surface for the latch side dropping before the batch is packed, and the galvanized finish is checked inside the tube ends, where the coating is thinnest.
Conclusion
Sheep gate fabrication requires understanding of sheep handling requirements, precision manufacturing, and corrosion protection expertise. Fulei Metal’s experience in livestock equipment fabrication makes us a trusted partner for sheep farming projects.
