The cost of a custom steel gate depends on the size of the opening, the type of gate (swing, track slider or cantilever slider), the frame and infill design, the posts and footings, the hardware, the finish, and whether it's automated and installed. That's why there's no honest single price for a steel gate: a 1 m pedestrian gate and an automated driveway gate share a material and little else. This guide explains what drives the number, where installation costs come from, and how to get and compare an accurate quote.
Why steel gates are priced job by job
A gate is a small amount of steel and a lot of work. The frame is cut, fitted and welded square; the infill is laid out and welded in; hinges, latches or rollers are fitted; and the whole thing is finished and installed on posts that have to carry it for decades. Each of those steps changes with the design and the site, so gate fabricators price from measurements and a design rather than a rate per metre.
The parts of a gate quote usually fall into five groups:
- The gate itself (frame, infill, fabrication)
- Posts, footings and any frame or track
- Hardware (hinges, latches, rollers, stops)
- Finish
- Automation and installation
What drives the cost of a custom steel gate
Size
Width and height set the amount of steel, but they also change the engineering. A wide swing leaf hanging from one post needs a stiffer, braced frame, heavier hinges and a stronger post to stop it sagging. Splitting a wide opening into a double gate keeps each leaf shorter and lighter, which can mean lighter hardware.
Type of gate
| Gate type | What adds cost |
|---|---|
| Pedestrian or garden gate | Small and simple; latch, closer and hinge choice matter most |
| Single swing driveway gate | Long leaf, heavy hinges, stiff post |
| Double swing gate | Two leaves, two hinge posts, a centre stop and drop rod |
| Track sliding gate | Wheels, a ground track set level across the opening, guide rollers |
| Cantilever sliding gate | A longer frame with a counterbalance tail, roller trucks, heavier posts and footings |
The right type depends on your driveway's slope, space and winter conditions. Our guide to steel driveway gates: swing vs sliding covers that decision.
Frame and infill design
The infill is what most people picture when they think of a gate, and it's one of the biggest variables:
- Vertical pickets or bars: efficient and classic; picket count and spacing drive welding time.
- Flat bar or horizontal slats: clean modern lines; more cutting and fitting for tight, even spacing.
- Solid or privacy panels: fewer welds, but more weight and much more wind load on the posts and hinges.
- Decorative ironwork style: scrolls, twisted bars, collars, spear tops and arched tops take far more hours than a straight picket design.
- Cut panels or patterns: a pattern cut into sheet steel, framed into the gate, depends on the design and cutting time.
A matching gate and fence or railing can share details, which keeps the design consistent and can simplify fabrication.
Posts and footings
Posts carry the gate, and for swing gates they also resist a large bending load from the leaf hanging off one side. Steel HSS posts on base plates or set into concrete footings are typical. Footings must be deep and wide enough to resist frost movement and keep the post plumb, and the right depth depends on your soil and location. Hanging a gate on existing masonry pillars can be possible, but the pillars and their anchors have to be checked; see embedding steel posts in concrete vs base plates for the post options.
Hardware
Heavy-duty adjustable hinges, latches, drop rods, gate stops, closers for pedestrian gates, and roller assemblies or tracks for sliding gates. Quality hardware costs more up front and is the difference between a gate that swings freely for years and one that drags.
Finish
Steel gates need protection from rust, especially at the bottom where salt spray and snowmelt collect:
- Primer and paint: the lowest first cost, the most maintenance.
- Powder coat: a durable factory finish in many colours.
- Hot-dip galvanizing: the standard protection for exterior steel, done by a specialist galvanizer after fabrication.
- Galvanized plus paint or powder coat: colour over galvanized protection; usually the longest-lasting option.
Automation
An automated gate adds the operator, safety devices (photo eyes, safety edges, guarded rollers), controls and remotes, and an electrician to bring power. Operators are rated for weight and length, so a heavy steel leaf needs a suitably rated unit. In Canada, look for an operator certified to CSA C22.2 No. 247 and plan entrapment protection from the start. Automation can be a large share of a driveway gate's total.
Installation and site conditions
"Steel gate installation cost" covers more than hanging the gate:
- Removing an old gate, posts and footings
- Digging and pouring footings, or anchoring to existing concrete or masonry
- Setting posts plumb and hanging and adjusting the gate
- Track installation for sliding gates
- Slopes, rock, tree roots, buried services and poor access
- Field touch-up of the finish
Pedestrian gate vs driveway gate
| Pedestrian gate | Driveway gate | |
|---|---|---|
| Typical opening | Walkway width | Vehicle width |
| Frame | Light | Heavier, braced against sag |
| Posts | Smaller posts and footings | Larger posts, deeper footings |
| Hardware | Hinges, latch, often a self-closer | Heavy hinges or rollers, stops, drop rods |
| Automation | Rare (sometimes an electric lock) | Common |
Why online gate cost calculators fall short
Steel gate cost calculators usually ask for width, height and a style, then multiply. They can't see your slope, your posts, your soil, your hardware choice, whether the gate will be automated, or how hard the site is to work on, and those are often what separate one quote from another. Use a calculator, if at all, to decide whether a project is worth pursuing, not to judge a quote.
How to compare steel gate quotes
Make sure each quote covers the same:
- Gate type, opening width and height
- Frame sections and infill design
- Posts, footings and any track
- Hardware brand or grade
- Finish system
- Operator, safety devices and electrical work, if automated
- Removal of the old gate, delivery and installation
- Any permit or by-law review
If one quote is much lower, check whether it leaves out posts, galvanizing, safety devices or installation. Driveway gates are usually governed by your municipality's fence by-law, so confirm height and design rules before you finalize.
How to keep a custom gate within budget
- Keep the infill simple where the gate isn't on show.
- Use a double gate instead of one very wide leaf when it suits the space.
- Choose the gate type for the site. A cantilever slider costs more than a swing gate, but on a sloped or snowy driveway it may avoid problems that cost more later.
- Plan automation early so the gate, posts and operator are designed together.
- Choose the finish once. Galvanizing plus a colour coat costs more up front but saves repainting.

Quotes are free. For a list of what to measure and photograph, see getting a custom steel gate quote, and for material choices, steel vs iron vs aluminum gates.
Send your opening width, height, photos and the style you like and we'll price it. We can prime or galvanize the gate to suit the job; the gate operator and installation are handled by your installer or contractor. See our steel products for the other miscellaneous steel we make.
Frequently asked questions
How much does a steel gate cost?
It depends on the opening size, the type of gate, the infill design, the posts and footings, the hardware, the finish, and whether it's automated and installed. A small pedestrian gate and an automated cantilever driveway gate are very different jobs, so get a quote built from your measurements.
Why is a steel driveway gate priced per job?
Most of the cost is fabrication time, hardware, finishing and installation, which change with the design and the site. Two gates with the same width can take very different amounts of work depending on infill, slope, posts and automation.
What adds the most to steel gate installation cost?
Posts and footings, automation and electrical work, and difficult site conditions such as slopes, existing masonry pillars or poor access. Removing an old gate and its posts also adds work.
Are online steel gate cost calculators accurate?
They give a rough idea at best. They usually can't account for your infill, slope, posts, hardware, finish, operator or local labour, so the final quote can differ a lot. A quote from your measurements and photos is the reliable number.
Is an iron gate more expensive than a steel gate?
Most iron-style gates are made from mild steel, so the difference comes from the design: scrolls, forged details and castings take more work than a plain picket gate. Genuine wrought iron is a specialist restoration material.
