Composite vs metal fencing
Composite wins on privacy, sound dampening, and corrosion resistance; metal wins on perimeter security and very long unmaintained life in the right alloy.
Aluminum and steel fencing are dimensionally stable and require little maintenance, which is why they show up around pools, parks, and commercial perimeters. The trade-off is privacy and acoustics: an open picket gives you neither. Compoxen is the privacy-and-acoustics answer when metal is overkill or the wrong shape.

| Attribute | Compoxen composite | Metal | Winner |
|---|---|---|---|
| Warranty | 20 years | 10–20 years typical | |
| Privacy | Full privacy panels | Open picket — no privacy | |
| Sound dampening | Measurable | Negligible (open picket) | |
| Corrosion | None — non-metallic | Rusts at fasteners and cuts | |
| Heat conduction | Low (composite) | High — too hot to touch in summer sun | |
| Impact resistance | High | Dents (aluminum), bends (steel) | |
| Color options | 5 architect-led palettes | Powder-coat black/bronze typical | |
| Coastal salt air | No corrosion | Aluminum OK, steel fails fast | |
| Security perimeter | Privacy fence — not a picket | Steel pickets are hard to climb | |
| Pool code | Available in code-compliant heights | Standard pool-code option | |
| Upfront install $ | $45–$85 / linear ft | $30–$60 / linear ft (aluminum) |
Choose composite if…
- Privacy from neighbors or the street is the goal.
- You want sound dampening from a road or shared boundary.
- You live near salt air and have seen steel fail.
- Hot afternoon sun makes a metal fence dangerous to touch.
Choose metal if…
- You need an open-sightline perimeter (parks, pool decks, view lots).
- Security against climbing is the primary requirement.
- You want the cheapest possible aluminum picket in a black powder coat.
Privacy is the deciding factor
Most "do I want metal or composite?" conversations end as soon as privacy comes up. A six-foot ornamental aluminum fence is still a fence you can see through. If a homeowner wants visual separation from a neighbor, a road, or a pool, the answer is composite (or wood, or vinyl). Metal is the right answer for security perimeters and view-preserving boundaries — different jobs.
Heat and touch safety
A south-facing aluminum picket in summer easily clears 140°F surface temperature, which is hot enough to burn skin on contact. Compoxen composite stays substantially cooler and is safe to touch.
Corrosion at the joints
Even powder-coated steel eventually corrodes where the coating is scratched at fasteners and cuts. Aluminum fares better but the mounting hardware is still steel. Composite is non-metallic end-to-end with hidden composite fasteners, so corrosion is not in the failure-mode list.
