Aluminum and wrought iron fences both offer a strong, classic look. Aluminum is lightweight, rust-resistant, and easier to maintain. Wrought iron is heavier and traditionally hand-forged, but it rusts and needs painting. Here’s how they compare on cost, upkeep, and durability.
Overview of Aluminum Fencing
Aluminum fences are made from aluminum alloy, usually hollow or solid extruded rails and pickets. They’re powder-coated or anodized to resist rust and come in black, white, bronze, and other colors. Aluminum is much lighter than wrought iron, which makes shipping and installation simpler. Most residential aluminum fences are sold in prefabricated sections that bolt together around posts.
Because aluminum doesn’t rust, it holds up well near pools, in coastal areas, and in humid climates. It won’t stain concrete or pavers from rust runoff. Aluminum fences are often used for pool enclosures, front yards, and property boundaries where you want visibility and a clean look without heavy maintenance.
Overview of Wrought Iron Fencing
Traditional wrought iron is iron that has been heated and shaped by hand or machine. Today, many “wrought iron” fences are actually mild steel formed to look like classic wrought iron. True wrought iron is rare and expensive. Either way, these fences are heavy, solid, and known for ornate scrollwork and decorative tops.
Wrought iron and steel fences rust when exposed to moisture unless they’re coated and maintained. They need priming and painting every few years to prevent corrosion. In wet or salty environments, rust can appear sooner. The weight of the material also means higher shipping costs and more labor during installation.
Cost Comparison
Use our fence cost calculator for a custom estimate. Below are typical price ranges per linear foot, installed.
| Material | Per linear foot (installed) | 100 ft fence |
|---|---|---|
| Aluminum (standard) | $25–$40 | $2,500–$4,000 |
| Aluminum (premium) | $35–$55 | $3,500–$5,500 |
| Wrought iron / steel (standard) | $30–$50 | $3,000–$5,000 |
| Wrought iron (custom) | $50–$100+ | $5,000–$10,000+ |
Maintenance Comparison
| Task | Aluminum | Wrought Iron |
|---|---|---|
| Rust prevention | Not needed | Priming and painting every 3–5 years |
| Washing | Occasional soap and water | Same; check for rust spots |
| Scratch repair | Touch-up paint available | Sand and repaint affected area |
| Lifespan | 30+ years | 20–30 years with good upkeep |
Pros and Cons
Aluminum Fence Pros
- Rust-resistant. Won’t corrode in rain, pool spray, or coastal air.
- Low maintenance. No painting or sealing required.
- Lightweight. Easier to handle and install than wrought iron.
- Won’t stain surfaces. No rust runoff onto concrete or stone.
- Good for pools. Many designs meet pool safety codes.
Aluminum Fence Cons
- Can dent. Softer than steel; impacts can leave dents.
- Less ornamental. Fewer hand-forged, custom design options.
- Hollow vs solid. Cheaper aluminum may feel less substantial.
Wrought Iron Fence Pros
- Strong and heavy. Resists impact better than aluminum.
- Ornate designs. Scrolls, finials, and custom patterns available.
- Classic look. Traditional elegance for historic or formal homes.
- Repairable. Bent sections can sometimes be bent back or replaced.
Wrought Iron Fence Cons
- Rust. Requires regular painting to prevent corrosion.
- Heavy. Harder to ship, handle, and install.
- Rust stains. Can discolor adjacent concrete or stone.
- Higher upkeep cost. Painting labor and materials add up.
Which Is Better for Your Climate?
In humid, rainy, or coastal areas, aluminum is usually the better choice. It resists rust and needs little maintenance. Wrought iron can work in dry climates, but even there it will eventually need painting. Near pools or in regions with salt air, wrought iron rusts faster unless it’s galvanized or coated and kept in top condition.
When to Choose Aluminum
Choose aluminum if you want a metal fence with minimal upkeep. It’s ideal for pool fencing, modern or casual landscapes, and anyone who doesn’t want to paint every few years. Aluminum also suits budget-conscious projects where custom wrought iron would be too expensive. For more metal fence ideas, see our decorative metal fence designs guide.
When to Choose Wrought Iron
Choose wrought iron if you want ornate scrollwork, a historic or formal look, and don’t mind periodic painting. It fits traditional homes, estates, and commercial properties where the classic aesthetic matters. Be sure to factor in long-term maintenance costs when budgeting. Compare options with our fence cost calculator before you commit.
Installation Notes
Both aluminum and wrought iron need solid post footings, usually concrete. Aluminum sections are lighter and faster to install. Wrought iron sections are heavy and may need extra workers or equipment. Gate hardware must be sized for the weight of the gate—wrought iron gates often need heavy-duty hinges. Check local codes for height and spacing requirements, especially for pool fences.
Pool Fence Considerations
Many homeowners choose metal for pool fencing. Aluminum is ideal: it won’t rust from pool chemicals or splash. Wrought iron can work but needs careful maintenance—rust stains from corroding metal can run onto pool decks and stain concrete or pavers. Pool fences must meet local safety codes: typically 4 feet minimum height, no climbable openings, and self-closing, self-latching gates. Aluminum pool fences come in styles that meet these requirements. Have your installer verify code compliance before finalizing the design.
Resale Value
Both aluminum and wrought iron can add curb appeal and help with resale. Buyers often prefer low-maintenance options, which favors aluminum. Wrought iron appeals to buyers who value traditional or ornate styling. A well-maintained metal fence in good condition is generally a plus. A rusty, peeling wrought iron fence can be a negative. If you’re selling within a few years and want minimal upkeep, aluminum is the safer bet.
FAQs
Does aluminum fence rust?
No. Aluminum does not rust. It can oxidize to a dull gray over many years, but it won’t corrode or flake like iron or steel.
Is wrought iron more secure than aluminum?
Both can be secure when installed correctly. Wrought iron is harder and heavier, but aluminum can be just as effective as a barrier when built to proper height and strength.
How often do you paint wrought iron?
Every 3–5 years is typical. In humid or coastal areas, you may need to paint more often to prevent rust.
Can aluminum fence look like wrought iron?
Yes. Many aluminum fences mimic wrought iron styles with similar picket and scroll designs. From a distance they can look very similar.
Which is cheaper, aluminum or wrought iron?
Standard aluminum is often slightly cheaper than wrought iron. Custom wrought iron is usually much more expensive than aluminum.
