Aluminium, steel and composite sliding gates compared
Hot-dip galvanised steel (with steel bars or composite/hardwood infill) is the strongest value choice at €2,200 to €3,500 manual or €3,000 to €5,000 electric. Welded marine-grade powder-coated aluminium (€3,200 to €4,200 manual, €4,200 to €7,500+ electric) weighs half as much on the motor and rollers and can never rust, even on coastal driveways.

Estimated fitted price
€5,100 to €10,000 fitted
Gate & automation: €4,200–€7,500 · Groundworks/beam: +€500–€1,600 · Access control: +€400–€900
Guide price for an electric powder-coated aluminium tracked sliding gate, with keypad and GSM mobile opener (+€400–€900). Allow clear side run-back space along the boundary wall of at least the opening width plus 450mm–600mm behind the pier. All automated sliding gates in Ireland must include EN 12453 force limitation, resistive safety edges on leading and rear trapping points, and inner/outer photocells.

| Gate material | Typical 3.6m leaf weight | Electric fitted cost | Rust & maintenance | Privacy & styling |
|---|---|---|---|---|
| Galvanised & powder-coated steel (railed / ornate) | 180 to 280 kg | €3,000 to €5,000 | Hot-dip galvanised to EN ISO 1461; 25+ yr rust protection | Open rails let wind through; finial, flat-bar or heritage styles |
| Galvanised steel frame + composite woodgrain boards | 240 to 360 kg | €3,300 to €5,400 | Zero painting or oiling; composite boards never rot or warp | 100% solid privacy in walnut, oak, teak or anthracite grey |
| Galvanised steel frame + solid hardwood (Iroko / Oak) | 260 to 380 kg | €3,600 to €6,200 | Timber boards need UV oil/stain every 12 to 24 months | Authentic natural hardwood grain; heavier on motor as wood absorbs rain |
| Marine-grade powder-coated Aluminium (Qualicoat) | 90 to 160 kg | €4,200 to €7,500+ | 100% rust-proof forever — even within 1 km of the sea | Sleek horizontal slats, wind-passing louvres or woodgrain sublimation |
Why composite infill has largely replaced softwood on steel frames
On a traditional timber-infill sliding gate, red deal or cedar tongue-and-groove boards absorb rainwater in winter — adding up to 35% to the gate's weight on the motor — and shrink in summer sun, opening gaps and warping the frame if not oiled regularly.
Wood-polymer composite (WPC) or aluminium-core boards slot neatly into a 50mm × 50mm or 60mm × 40mm hot-dip galvanised, powder-coated steel box frame. They give full privacy, absorb zero moisture, never change weight between January and July, and clean down with a garden hose.
Three reasons lightweight aluminium excels on sliding gates
- Half the rolling mass. A 4-metre solid-privacy aluminium sliding gate typically weighs 110–140 kg, compared with 280–350 kg for a steel-and-composite gate. Less inertia means quieter rolling, less wear on track bearings or cantilever carriages, and lower-stress safety stopping distances.
- No rust bleed on light renders or granite piers. Even galvanised steel can weep rust if drilled on site without cold-galv treatment. Marine-grade 6063-T6 aluminium with a Qualicoat Seaside powder coat cannot rust.
- Louvred slats for windy sites. Aluminium horizontal louvre profiles give full visual privacy from the road while letting storm gusts bleed through the angled blades.

Questions homeowners ask
How long does a hot-dip galvanised steel sliding gate last in Ireland?
When the fully welded steel frame is submerged in molten zinc at 450°C (hot-dip galvanising to EN ISO 1461) before etching and powder-coating, the zinc layer protects the steel both inside and outside the hollow box section for 25 to 40+ years.
Can aluminium sliding gates look like real wood?
Yes. Sublimation woodgrain powder-coating bakes a textured golden oak, walnut or driftwood grain directly into the marine-grade polyester coating on the aluminium slats, giving the warmth of timber with zero oiling.
