What A Class Fencing builds
About Our Farm Perimeter Fences
A perimeter fence is the backbone of any working farm or ranch. It's the longest run on the property, the most exposed to weather and wildlife, and the most expensive to do twice. A Class Fencing builds farm perimeter fences across Southern Alberta with the right corner braces, the right wire spacing, and the right post depth to last 30+ years.

More About Farm Perimeter Fences
Built For Alberta — The A Class Way
Farm perimeter fencing around Calgary has to handle the long haul — kilometres of fence line in some cases, exposed to chinook winds, heavy snow, deer pressure, and seasonal flooding. A Class Fencing has built farm perimeter fences across Wheatland County, Foothills County, Rocky View County, Mountain View County, and out into ranching country. We bring the right gear (post pounders, wire spinners, augers, fence trucks) to put long runs in fast and straight.
The most important part of any perimeter fence is the corners and the braces. A weak H-brace will let the entire fence sag within a year. A Class Fencing builds proper double-H or even triple-H brace assemblies at every corner, gate, and tension change, with diagonal compression bracing wired in correctly. The wire then has something to actually tension against, and your perimeter stays tight for decades.

We work in high-tensile smooth wire for cattle perimeters, woven page wire for mixed livestock and wildlife exclusion, and barbed wire where the budget calls for it. Wood posts are pressure-treated for ground contact; steel T-posts are heavy-gauge with proper spacing. We also build hi-vis perimeter fences with vinyl rail or rail-on-mesh for properties where the perimeter is visible from the road.
Long-run perimeter fence sees the full punishment of Alberta weather. Chinook freeze-thaw cycles work soil around posts, prairie wind racks under-tensioned wire, deer pressure forces taller specs near wooded property lines, and snow drift loads bend under-spec T-posts. A Class Fencing engineers for all of it. Wood corner posts go 4+ feet deep with concrete where soil demands it. Brace assemblies are double or triple H — depending on the wire tension load. Wire is tensioned to manufacturer-spec PSI with inline strainers. The result is perimeter fence that stays tight and straight through Alberta seasons.

Perimeter fence pricing is one of the most efficient per-foot in agricultural fencing because of the long uninterrupted runs. High-tensile smooth wire runs the cheapest ($5-$10 per foot). Page wire and woven sits mid-range ($8-$15). Barbed wire is in between depending on number of strands. Costs add up at corners (each brace is a fixed-cost assembly) and at gates. A Class Fencing quotes by linear foot for runs and by item for corners, gates, and braces, so you can scope the project precisely.
Maintenance is the lightest of any fence type when it's built right. Annual walk-and-tighten in spring catches wire that stretched over winter. Corner assemblies should be visually inspected every 2-3 years for any loosening. Heavy snow years can require post-checking. Built to spec, an A Class Fencing perimeter fence holds tight for 30+ years.

Every perimeter fence build comes with a workmanship warranty in writing. Process: walk the line together, get a quote broken out by run/corner/gate, deposit confirms the schedule, balance on completion. A typical mile of perimeter takes 7-14 working days depending on terrain, brace count, and gate spec. Call (403) 971-4882 to get on the schedule.

Common Questions
Farm Perimeter Fences FAQ
How many strands of wire for a cattle perimeter?
+
Typically 4-5 strands of high-tensile smooth wire or 4 strands of barbed for cattle. Top wire at 48-52 inches, evenly spaced. Number of strands depends on cattle breed, presence of calves, wildlife pressure, and whether you're combining strands with hot wire reinforcement.
What's the difference between an H-brace and a double-H?
+
An H-brace is two posts with a horizontal rail between them, diagonal-wired for compression — used at every corner, gate, and tension change. A double-H adds a third post and rail in line for longer wire spans or higher-tension wire. Triple-H is used at end-of-line with very long wire pulls. A Class Fencing matches brace strength to wire tension load.
Can you fence a quarter-section perimeter (one-mile sides)?
+
Yes. Quarter-section perimeters are some of our most common long-run jobs. A full quarter (160 acres, one-mile each side, four miles total perimeter) typically takes 4-6 weeks depending on terrain, brace count, gates, and crew size. We mobilize for the run with post pounders, wire spinners, and a sized crew.
How do you handle wildlife pressure on perimeters near woods?
+
For deer pressure we typically go taller (8-foot page wire) on the wooded side, or add high-tensile strands above standard 5-foot page wire. For elk we go to 8-ft minimum. For predator exclusion (coyote) we add buried L-footer mesh or a hot bottom wire. The spec depends on the wildlife and the livestock or crop being protected.
Can you rebuild an old perimeter fence?
+
Yes. A lot of our perimeter work is rebuilds of fences that are 20-40 years old. We replace rotted wood corners with new pressure-treated H-braces, re-stretch or replace wire, and re-set or replace failed T-posts. We walk the line with you and recommend rebuild-vs-replace section by section.
