How We Install Commercial Chain Link Fencing

Pipe sizes, wall thickness, security options and gates, and how we install commercial fence that stays straight and solid.

01 — Selection

Height, fabric & finish

Commercial fence is built heavier than residential: thicker fabric, bigger posts, and the option to add rails and barbed wire. We confirm every choice with your quote.

Taller specialty fence on request. Barbed wire is an option above 6′.

Privacy inserts

Slats woven through the fabric screen bins, equipment and yards. They catch wind, so posts go closer: 8′ max instead of 10′.

02 — Framework

Pipe sizes & wall thickness

Diameter sets the size of each post and rail; wall thickness sets its strength. Thicker walls give stiffer framework for taller fences, barbed wire, privacy inserts and high-traffic sites.

03 — Rails & security

Rails & barbed wire

Top rail · standard

Ties the posts together and holds the top of the fabric straight.

Mid rail · option

Adds rigidity to tall fences and makes the fabric harder to push in.

Bottom rail · option

Locks the bottom of the fabric so it can’t be lifted to crawl under. Bottom tension wire is the standard alternative.

Barbed wire

An option on fences above 6′. Three strands of barbed wire on steel arms along the top of the fence. Arms come single (angled out), double “V” or vertical. Barbed wire rules depend on zoning, so we confirm what’s allowed at your site.

04 — Gates

Pedestrian, swing & slide gates

Every gate is built with a square welded industrial frame. Pick the type by who and what goes through it.

Pedestrian gates

Typically 4′ wide for foot traffic. Self-closing, with panic hardware and access control available.

Swing gates

For larger openings. Single or double drive gates swing open for vehicles and equipment.

Gates with inserts

Welded frames carry privacy inserts for enclosures that need to stay screened.

  • Keypad entryCode, card or fob access control.

American slide gates

A wheel and fence track system: the gate rolls on wheels and runs along a track on the fence line as it opens.

Cantilever slide gates

The gate rides on rollers mounted to the posts beside the opening. No track in the ground, nothing to clear of snow or ice. Automation available: add a gate operator with keypads, remotes or access control.

Hang off a section

Gate posts are tied into a fence section. A lone post has nothing bracing it and leans over time.

Swing with the grade

Swing gates open toward the lower side so they clear the ground. The latch goes on the swing side.

Gate wheels

Wide swing gates can add a wheel on the free end to carry the weight and reduce sag.

05 — Layout, spacing & grade

Even spacing on real-world ground

Your layout

The layout is set when we put your quote together. Before install, we may need a few site details to place it exactly: survey pins, gate locations and widths, and any buried utilities.

Even spacing, not leftovers

Many installers set posts every 10′ and squeeze the leftover into short sections at the end. We measure each run and divide it evenly: 10′ max, 8′ with inserts. If a rock or buried line blocks a post, we re-divide the run, adding a post if needed.

Diagram: a typical 64-foot run with five 10-foot sections and two short 7-foot sections, compared with seven even 9-foot-1-3/4-inch sections, and the run re-divided around an underground rock

Most sites aren’t level

Most sites are graded to slope for drainage; some are close to level. Over a 50–100′ run, a level fence would leave a 6–12″ gap under one end. Instead, we run the top straight and follow the grade.

How we set the line

A string line across the top, measured off the ground, shows the top before we set the height. High spots get a little digging. A bottom rail or additional bottom wire can close valley gaps and keep a straight line. Steep slopes get a smooth curve, then run straight again.

Doing it right takes time — and it makes the biggest difference in how your fence looks for its lifetime.

06 — Posts & installation

Every post direct-driven

Line, terminal and gate posts are all driven straight into the ground, no concrete. A hollow steel post has a small surface area, so frost has very little to grab and push up. That push is called frost jacking, and it’s what lifts and leans fences after a Manitoba winter.

The driver damages the post top, so we drive each post just above fence height and cut it clean. Bigger diameters and thicker walls are available where the site needs more strength.

  3. Cut to height
