Welded steel mesh (358, 656, expanded metal), tubular steel pickets, hot-dip galvanized panels. Commercial, industrial, anti-climb security-rated.
Steel fence is the commercial workhorse beyond chain-link. Where chain-link is a perimeter marker, steel mesh and tubular profiles are security barriers — engineered to resist climbing, cutting, and impact. Fenced.ca stocks the full commercial steel range.
358 welded mesh (3″ × 0.5″ × 8 gauge — narrow rectangular apertures defeat finger and toe-hold climbing) is the residential-equivalent commercial standard, widely specified for school perimeter, utility substation, and data centre work. 656 welded mesh (6″ × 0.5″ × 6 gauge — heavier wire, slightly larger apertures) is prison-grade and used for federal and critical-infrastructure perimeter. Expanded metal offers a more architectural appearance and is common on parking-garage screening and rooftop mechanical enclosures. Tubular steel pickets in 1″ or 1-1/2″ square section with welded horizontal rails are the commercial-budget equivalent of aluminum ornamental — less ornate, more secure.
Finish: hot-dip galvanized is the universal substrate (sacrificial zinc protection for the 25–40 year service life expected of commercial perimeter). Powder-coat in safety yellow, black, or dark green available as a second-stage finish for visual integration.
Galvanized vs powder-coated steel: Hot-dip galvanized (zinc-coated steel by immersion) gives 40+ year service in inland environments and 25+ years coastal. Powder coating adds aesthetic colour but a coating crack starts rust at the breach. Best practice: galvanize THEN powder-coat (duplex finish) — combines corrosion protection with finish flexibility.
Commercial perimeter: Steel mesh, ornamental, palisade, and security combinations dominate industrial yards, data centres, electrical substations, and bulk-fuel terminals. 6-gauge welded wire mesh is the modern alternative to chain-link for commercial — looks cleaner, no visible mesh-edge selvage, fewer climb points.
Engineering: Steel posts engineered for wind load CSA S37 (telecom-grade) for tall security perimeters above 2.4 m. Footings sized to NBC 9.20 with frost-depth adjustment per region. Posts sleeved over galvanized rebar cages in concrete for maximum pullout resistance.
Pricing & lead time: Steel fence pricing: welded wire mesh commercial runs $45–85 LF installed, palisade security 2.4 m at $120–200 LF, anti-climb topping adds $15–30 LF, steel ornamental panels at $90–160 LF. CCDC-3 contract experience for capital projects. P.Eng-stamped drawings included for heights above 2.4 m. Lead time 3–8 weeks depending on coating spec and panel quantity.
How steel fence stacks up against the alternatives — at a residential height of six feet, in median Canadian markets.
Stake the line, check setback rules with the municipality, locate utilities (Info-Excavation in QC, Ontario One Call elsewhere).

Steel T-posts and wood posts each have their place. T-posts win on: install speed (driven in 30 seconds with a manual post driver, no concrete cure time), longevity (galvanized or painted T-posts last 25-40 years in most soils), cost ($8-12 each vs. $20-40 for a comparable cedar or PT post installed), and uniformity. Wood posts win on: lateral strength (a 4×4 PT post in concrete holds gates and tension corners better than a T-post), aesthetics (wood reads warmer for residential), repair (you can screw rails to wood, you need clips on T-post), and longevity in some soils (a T-post in wet acidic soil corrodes at the grade line in 10-15 years). Standard practice: T-posts on line, wood or steel pipe at corners and gates where structural load is highest. For pure farm fence, all-T-post is normal; for chain-link, line posts can be schedule-40 steel pipe set in concrete for a longer-life upgrade.
Steel T-posts should be driven so that the soil plate (the wide anchor wing welded near the bottom of the post) is fully buried plus 4-6 inches of post above the plate is still in the ground. For a standard 6-foot T-post that leaves about 4 feet above grade and 2 feet in the ground; for a 7-foot post about 4.5-5 feet above grade and 2-2.5 feet in. Driving deeper than that runs into diminishing returns and risks bending the post on a buried rock. Tools: a manual T-post driver (a heavy steel sleeve with handles) is the standard — slide it over the post, lift, drop, repeat. Hydraulic drivers exist for fencing crews. In rocky soil, switch to wood post in concrete; in deep loose sand or muck, drive deeper or upgrade to a longer post. Frost heave can lift T-posts over winters; for permanent line work in frost-prone soil add a clip wire from post to a buried T-post anchor or pour a small concrete collar.
Common T-post problems and their fixes: 1) Bending on impact — a 12.5-gauge T-post bends under a vehicle hit or tractor side-swipe; upgrade to a 14-gauge studded or schedule-40 pipe at access points. 2) Frost heave — repeated freeze-thaw lifts T-posts in clay soils; add a buried T-anchor or concrete collar. 3) Grade-line corrosion — galvanized or painted T-posts corrode at the soil/air interface where moisture cycles; expect 25-40 years in most soils, 10-15 in wet acidic conditions; coat the grade line with bitumen or fence-post sealer for prevention. 4) Clip slip — wire ties or hog rings on T-post studs walk over time under wind load; switch to dedicated T-post clips or replace ties annually. 5) Sharp top hazard — exposed T-post tops cut livestock and people; install plastic safety caps. 6) Magnetic interference — T-posts near aluminum chain-link tension wire can cause galvanic corrosion in salt; isolate with rubber bushings.
T-post wins on strength for almost every fence application. A standard 1.33 lb/ft studded T-post has substantially higher resistance to bending in both axes than a U-post of similar gauge, because the T-profile (three perpendicular flanges) resists deflection from any direction, while the U-profile (two parallel flanges) resists well in one axis and poorly perpendicular. T-posts are also driven straighter — the anchor plate near the base resists rotation during install. U-posts have niches: they're cheaper, lighter, and easier to drive in shallow soils, so they work for temporary garden fence, snow fence frames, and signage where wind load and animal pressure are low. For permanent fence carrying wire tension (chain-link, woven wire, high-tensile), spec T-posts. For 3-strand barbed cattle fence on flat ground, either works; for woven wire on rolling pasture, only T-posts.
Yes — Fenced.ca operates as a Canada-wide multi-category fence supplier, with our Canada-wide network in Toronto, Montreal, Calgary, and Vancouver. We ship every fence category we carry — chain-link, wood, vinyl, aluminum, wrought-iron, steel, privacy, picket, split-rail, glass pool, temporary, security, farm, dog, electric, garden, gabion, snow, silt, and driveway gates — to all 10 provinces. The three Territories are quote-on-request because freight is the dominant cost line; we will quote Whitehorse, Yellowknife, and Iqaluit, but a flatbed lane has to be confirmed first. We do not ship internationally. Installation is offered nationally through our vetted installer network where coverage exists, and supply-only for everything else.
Supply means we ship materials — panels, posts, hardware, gates — to your jobsite or yard, and you (or your contractor) install. This is our primary business and covers all 20 fence categories nationally. Rental is offered for temporary fence (construction site fence, event fence, crowd-control barrier), silt fence, and snow fence — categories where the fence comes down after a defined project window. Rental includes delivery, pick-up, and weekly billing; minimum rental is typically one week, with multi-month and multi-site rates available. Installation is offered through our regional installer network in major metros (GTA, Montreal, Calgary, Vancouver, Ottawa, Edmonton) and quoted per-project elsewhere. You can mix and match: supply only, rental only, or supply + install as a turnkey package.
