Aluminum fencing is the quiet workhorse of the residential and commercial fence world. It looks like wrought iron, weighs a fraction as much, never rusts, and installs faster than any decorative metal option on the market. It's the default around pools because it meets most municipal pool-code requirements out of the box - and the default for front-yard enclosures because it doesn't block sight lines.
The catch: aluminum is sold in factory-welded panels (usually 6 ft long) with specific grade ratings. Getting the grade wrong means paying for industrial-strength panels on a residential job, or - worse - installing residential panels on a pool that fails inspection.
Aluminum Fence Cost by Grade
Aluminum fencing is sold in three tiers. Installed cost per linear foot, 54" height, panels set on concrete-poured posts:
- Residential (light-gauge): $28 – $40 per linear foot
- Commercial: $40 – $55 per linear foot
- Industrial / security-grade: $55 – $75 per linear foot
- Pool-code gates (self-closing, self-latching): $350 – $600 each
A typical 150-foot residential pool enclosure in residential-grade aluminum runs
$4,500–$6,200 installed, including two self-closing gates.
What Drives Aluminum Fence Estimates
1Panel Length & Post Count
Aluminum panels come pre-welded in 6 ft sections with pickets already attached.
Each panel needs a post on each end - your post count is (number of panels) + 1
plus extra terminal posts at corners and gates. Never spec fewer posts than panels + 1.
2Powder-Coat Color & Warranty
Black is the standard and cheapest. Bronze, white, and green add 5–10% material cost. Reputable manufacturers offer 20-year powder-coat warranties - always confirm the warranty document exists before quoting, because peeling coatings are the #1 complaint on cheap aluminum.
3Pool Code Compliance
Pool-code aluminum must be at least 48 inches tall with picket gaps under 4 inches and self-closing, self-latching gates with the latch at least 54 inches above grade. If the job is around a pool, spec pool-code panels from day one - retrofitting gate hardware after fail inspection is always more expensive than doing it right the first time.
4Terrain & Racking
Aluminum panels can "rack" (pivot at the posts) to follow a moderate slope without stepping. Sharp grade changes force you to step the panels, adding 10–15% material cost and more complex post-setting. Walk the line before quoting.
