Specs That Matter: Composite + Cantilever
Composite At a Glance
| Weight | Light to medium (60-180 lbs per panel) |
| Rust | High - no rust, no rot, holds up in sun |
| Upkeep | Clean once a year. That is it |
| How long it lasts | 25-35 years |
| Best for | Near the coast, Low upkeep, Looks like wood, Budget-friendly |
Composite looks like wood but won't rot, warp, or attract termites. It's the best of both worlds.
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 Composite
✅ Choose when:
- You want wood look without wood upkeep
- Coastal or humid. You want durability.
- Low upkeep. Install and forget.
- No rot. No bugs. Holds up in sun.
❌ Think twice when:
- You need max security. Composite is lighter than steel.
- You want 50+ years
- Opening over 24 ft. Composite can flex.
💡 Pro tip: Composite works with modern homes, coastal properties, and vinyl fencing. Looks like wood. Lasts longer.
Cantilever Gate: What to Know
Best for: Uneven ground. Gravel. Steep slopes. Snow and ice. The gate floats. Ground does not matter. Best for ranch and rural properties.
⚠️ Watch out: The gate needs extra length. A 20-ft opening needs a 30-ft gate. The extra part balances it. Many people are surprised how much fence space it uses.
💡 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.

Every market is different. What works in one city may cost more or require different permits in another. Here's the San Antonio breakdown.
State: TX Climate zone: Dry Heat Permits: Building permit required for structures over 6 ft; SAWS utility clearance needed
San Antonio Properties & Styles
Typical lots: Ranch-style lots in outer suburbs, traditional lots in Alamo Heights and Terrell Hills, acreage properties north of 1604 Popular gate styles: Wrought iron with Spanish colonial details, rustic wood and iron combinations, Hill Country stone pillars with metal gates
HOA & Architectural Review
Heads up: HOAs in new developments (Stone Oak, Helotes) are moderately strict. Older neighborhoods like Alamo Heights have architectural review but are more flexible on traditional designs.
Climate Impact on Gate Selection
UV exposure degrades powder coatings and dries out wood. For gates in San Antonio, choose UV-stabilized powder coat colors; apply UV-protectant sealant to wood gates annually.
Recommended inspection frequency: Inspect coatings quarterly, lubricate moving parts every 3 months
Composite in San Antonio's Climate
Composite holds up well in desert climates. The material does not warp or crack from low humidity. Choose a light-colored composite to minimize heat absorption; dark colors can get hot to the touch in direct sun.
