Ornamental iron and aluminum fence Houston, TX look remarkably similar at first glance — both are metal, decorative, and available in spear-top, flat-top, and traditional picket styles. But they differ significantly in weight, rust resistance, strength, and long-term cost. For Houston homeowners, where Gulf Coast humidity and salt air accelerate corrosion, the choice between these materials has real consequences.
| Factor | Ornamental Iron / Steel | Aluminum |
|---|---|---|
| Cost (installed) | $25–100/ft (higher for custom) | $20–40/ft |
| Weight | Heavy (30–80 lbs/panel) | Lightweight (12–25 lbs/panel) |
| Rust Resistance | Rusts without maintenance | Will not rust — ever |
| Strength | Significantly stronger | Adequate for decorative use |
| Lifespan | 50+ years (maintained) | 30+ years; indefinite rust-free |
| Coastal Performance | Requires extra maintenance | Excellent |
| Custom Design | Highly customizable; weld-able | Good; limited custom welding |
| Pool Fence Use | Excellent | Excellent; common choice |
| HOA Approval | Widely approved | Many HOAs approve; verify first |
Houston's climate is particularly demanding on ferrous metals (iron and steel). The city's average relative humidity exceeds 75% throughout the year, and Gulf Coast properties within 10–15 miles of open water experience salt-laden air that dramatically accelerates oxidation. ornamental iron fence Houston, TX without proper coating will show surface rust within 2–3 years in inland Houston and within 12–18 months in coastal areas.
