Composite vs Timber vs Metal Gates

Composite needs the least upkeep: no painting or staining, and the aluminium frame doesn't rust. Timber is cheaper to buy but needs treating every year or two. Steel is strongest but rusts where the coating is broken.

Timber wins on price on the day and on looks for a traditional house. Composite wins over the years: no stain, no oil, no rot at the bottom rail. Steel and iron win on strength and on the open, barred look, and lose to rust where the coating is chipped.

Near the sea, choose an aluminium frame: salt air finds every chip in steel. On a windy, open site, remember a solid composite or timber gate catches the wind where an open metal gate doesn't.

Questions

Questions we get asked

Is composite better than timber for a gate?

Composite needs the least upkeep: no painting or staining, and the aluminium frame doesn't rust. Timber is cheaper to buy but needs treating every year or two. Steel is strongest but rusts where the coating is broken.

Do composite gates rot?

The boards don't rot or splinter. Hang the gate so it isn't sitting in water, as with any gate.

Are composite gates more expensive than timber?

Usually more than a ready-made timber gate, less over the years because there's no staining. A composite side gate kit is €400–€500.

Which is best near the sea?

Composite boards on an aluminium frame: neither rusts in salty air.
