Steel gates: structural strength, priced sensibly
Fabricated steel is the workhorse of gate making — stronger and stiffer than aluminium, more affordable than hand-worked wrought iron, and the basis of every security-rated design. Galvanised and powder-coated steel gates for Surrey properties run £4,500–£12,000 installed and automated, spanning contemporary panel designs to heavy estate work.
Where steel is the right answer
- Wide spans. Steel's stiffness carries 5m+ sliding leaves and tall boarded gates without the section sizes aluminium would need.
- Security-led briefs. Anti-climb designs, heavy solid-bar infills and certified security gates are steel territory — aluminium equivalents don't exist at the top ratings.
- Iron looks at a working budget. Clean vertical-bar steel gates deliver 80% of wrought iron's presence at 50–60% of the cost, because fabrication replaces hand forging. Where the difference shows — and whether it matters at your viewing distance — is set out honestly on the wrought iron page.
- Steel-framed hybrids. The frame behind timber-clad gates and many premium boarded designs is steel doing the structural work invisibly.
The protection system is the whole game
Steel's only weakness is corrosion, so the specification of the coating system matters more than any other line in a steel gate quote:
| System | Realistic life in Surrey conditions | Verdict |
|---|---|---|
| Paint only | 1–3 winters before rust spots | Reject it |
| Zinc-rich primer + paint | 5–8 years, touch-ups needed | Budget work only |
| Hot-zinc spray + powder coat | 15–25 years | Our standard |
| Hot-dip galvanised + powder coat | 25–40 years | Closed sections, exposed sites |
Two checks to make on any steel gate quote: are closed sections vented and drained (trapped condensation rusts gates from the inside out), and is the gate galvanised after fabrication, not built from pre-galv tube with raw welded joints?
Automation notes for heavy leaves
Steel leaves reward properly sized automation: hydraulic rams or high-torque underground motors for pairs beyond ~250kg, rack-driven sliders with motor duty cycles matched to leaf mass. The hydraulic vs electromechanical comparison covers the decision; the short version is that heavy steel is exactly where hydraulics earn their premium.

Frequently asked questions
What's the difference between steel and wrought iron gates?
Material-wise, modern 'wrought iron' gates are steel — the difference is workmanship: hand-forged scrolls, tapers and collars versus fabricated bar and box section. Fabricated steel costs less and suits contemporary design; hand-worked iron is for period authenticity.
Will steel gates rust?
Only if the coating system is inadequate. Hot-zinc-sprayed or galvanised gates with powder coat don't rust through; budget paint-only gates rust visibly within a couple of Surrey winters.
Are steel gates too heavy to automate?
No — weight simply dictates the motor class. Hydraulic and heavy-duty underground operators handle leaves of 400–500kg routinely; the critical items are hinge specification and post foundations, which we engineer accordingly.
