| Rust | High - does not rust. Great near the ocean |
| Upkeep | Clean once a year. Little else |
| How long it lasts | 30-40 years |
| Best for | Near the coast, DIY install, Budget-friendly, Low upkeep |
Aluminum is one-third the weight of steel.
Cantilever Gate At a Glance
| Min width | 10 ft |
| Max width | 60 ft |
| Space needed | Space beside fence for gate - 1.5× gate width (extra part balances it) |
| Best for | Any slope - gate floats above ground, Uneven ground, Gravel driveways |
| Opener type | Chain or gear drive |
Cantilever gates float above the ground. No track. They handle slopes and gravel that other gates cannot.
When to Choose Aluminum
✅ Choose when:
- You live near the coast or in humidity. Aluminum does not rust.
- Low upkeep is your top priority. Install and forget.
- Budget matters. You still want quality.
- You might install it yourself. Aluminum is light.
❌ Think twice when:
- You need max security. Aluminum bends easier than steel.
- You want the heavy look of iron or steel
- Your opening is over 20 ft. Aluminum can sag.
💡 Pro tip: Aluminum works with any style. Many paint colors. Great with stucco and modern homes. Solar openers work well. Aluminum uses little power.

💡 Pro tip: Gravel driveway? Cantilever is your answer. No track on the ground. No gravel jams. No track to clean. Other gate types struggle with gravel.
