Importing gates from China to Australia: steel, aluminium, and automation
19 July 2026 · 9 min read
Why builders import gates from China
A custom driveway gate is one of those finishing items that quietly blows a budget. A bespoke steel or aluminium entry gate with automation, bought and installed through an Australian fabricator, commonly runs $6,000 to $20,000 depending on size, design, and motor. The same gate, sourced direct from a Chinese factory, often lands in Australia for $2,500 to $7,000 including the automation kit.
The saving is real because you are removing the local fabricator's margin and labour, which is where most of the cost sits. What you take on instead is the sourcing, the freight, and a few compliance checks. This guide covers how to do that well: choosing steel or aluminium, getting the automation right, sizing and corrosion protection, what a gate costs landed, and the mistakes that turn a bargain into a headache.
Steel or aluminium: which gate material
The material choice drives cost, weight, maintenance, and the size of motor you need. Both are made well in China. The right pick depends on the span, the look, and the environment.
Steel is stronger for a given section, which matters for wide or heavy feature gates and for security. It is heavier, so it needs a more robust motor and stronger posts, and it will rust if the coating is compromised. For steel to last in Australian conditions, hot-dip galvanising before powder coating is the specification that holds up, particularly within a few kilometres of the coast.
Aluminium is lighter, will not rust, and is the default for most modern residential entry gates. It runs a smaller, cheaper motor and puts less load on posts and hinges. It is softer than steel, so heavy vehicle-gate spans need proper internal framing to stay rigid. Powder-coated aluminium is the common finish.
| Factor | Steel | Aluminium |
|---|---|---|
| Strength for span | Higher | Good with proper framing |
| Weight | Heavy | Light |
| Corrosion | Rusts if coating fails, galvanise first | Does not rust |
| Motor size needed | Larger | Smaller |
| Best for | Security, wide heavy gates, ornate | Most residential, coastal, low maintenance |
For coastal sites, aluminium or hot-dip galvanised steel with a marine-grade powder coat is the sensible baseline. Ask the factory to confirm the coating system in writing.
Automation: motors, sensors, and access control
Automation is where a gate becomes a system, and where cheap imports go wrong if you do not specify properly. A good factory can supply the gate leaf, the motor, the controller, the safety sensors, and the intercom as one pre-matched package, so your electrician only connects mains power.
Two mechanisms cover most jobs:
- Sliding gate motors run a rack along the bottom rail. They suit wide driveways and sloping or windy sites, and need side room for the gate to slide open.
- Swing gate motors (ram or articulated arm) suit level driveways with room for the leaves to swing. Underground motors give the cleanest look at higher cost.
Match the motor's duty rating and pull to the gate weight and span, and add margin. An undersized motor on a heavy steel gate is a warranty claim waiting to happen. Specify safety photocells (so the gate reverses on an obstruction), a manual release for power failures, and the access method you want: keypad, remote, intercom, or app.
Two compliance points that are easy to miss. First, the automation motor and controller are mains electrical equipment, so they must carry electrical approval and the RCM (the SAA/RCM electrical approval regime), backed by a registered responsible supplier. Second, an automated gate is a powered moving object, and there are safety requirements covering entrapment and crushing points. Confirm the current automated-gate safety and electrical requirements with your electrician or state regulator before you order. For how the electrical approval side works across products, see our guide to importing lighting and SAA approval.
Sizing, corrosion, and finish
Gates are made to your opening, so the dimensions in your purchase order are the gates you get. Give the factory the clear opening width, the ground slope, the post-to-post dimension, and the swing or slide direction. For sliding gates, remember the gate needs to be longer than the opening and needs run-back space beside it.
On finish and corrosion, the order of operations matters more than the colour:
- Steel: hot-dip galvanise, then a zinc-rich primer or powder-coat system over the top. Galvanising after fabrication protects the welds and cut edges, which are the first points to rust.
- Aluminium: a quality powder coat over a properly pre-treated surface. Ask for the coating standard and, near the coast, a marine or severe-environment grade.
Get the RAL or powder colour code into the contract, and ask for a coated sample coupon before production if the colour is critical. Coatings applied at the factory cannot be adjusted once the gate is on the water.
What a gate costs landed from China
For a single automated aluminium sliding gate, roughly 4m to 5m wide, with motor, sensors, and a keypad:
| Item | Range (AUD) |
|---|---|
| Factory price (gate plus automation kit) | $1,600–$4,200 |
| Crating and export packaging | $200–$450 |
| Sea freight (shared container) | $500–$1,100 |
| Customs duty (typically nil under ChAFTA) | $0–$250 |
| GST (10% of value + duty + freight) | $250–$600 |
| Clearance and delivery | $400–$700 |
| Total landed | roughly $3,000–$7,000 |
A comparable custom gate and automation supplied and installed through an Australian fabricator commonly runs $6,000 to $20,000. Installation on your end (posts, footings, electrician, commissioning) is extra either way, so compare like with like. For how the duty and GST lines are worked out, see our duty and GST guide, and for the freight side our container shipping cost guide.
Freight and crating for a bulky item
Gates are awkward freight: long, flat, heavy, and easy to bend or scratch if packed poorly. A single gate is rarely worth its own container, so most orders travel as part of a shared or consolidated load, which is one reason to buy gates alongside other materials for the same build.
Insist on a proper timber crate or steel A-frame, edge and corner protection, and separation between the gate leaf and the motor and hardware so nothing rubs in transit. A bent bottom rail or a gouged coating on arrival is expensive to fix and slow to replace. Pre-shipment inspection with a photo log before the crate is closed is cheap insurance on an item like this.
Common mistakes when importing gates
Undersizing the motor. Speccing a light-duty motor for a heavy steel gate is the most common failure. Match the motor to the real gate weight and add margin.
Skipping galvanising on steel. Powder coat alone over bare steel will rust from the welds and edges out, fast near the coast. Galvanise first.
Getting the opening dimensions wrong. Forgetting run-back space for a sliding gate, or the slope of the driveway, means a gate that binds or will not close. Measure the real opening and site.
Ignoring the electrical and safety compliance. The motor is mains equipment and needs electrical approval and the RCM, and the gate needs entrapment protection. Confirm both before ordering.
Underpacking for freight. A gate is long and heavy and dents easily. Demand a real crate and inspect before it is sealed.
Frequently asked questions
How much does it cost to import a gate from China to Australia? As a planning range, a single automated aluminium sliding gate lands at roughly $3,000 to $7,000 AUD including the motor, before your on-site installation. Steel and larger spans cost more. Get a live freight quote for your dates.
Do imported automated gates need to meet Australian standards? The automation motor and controller are mains electrical equipment and must carry electrical approval and the RCM, and an automated gate must meet the relevant safety requirements for powered moving barriers. Confirm the current requirements with your electrician or state regulator.
Steel or aluminium gate, which is better for Australia? Aluminium for most residential and coastal sites because it will not rust and runs a smaller motor. Steel for security and wide heavy or ornate gates, provided it is hot-dip galvanised before coating.
How long does a custom gate take? Custom gates typically take 20 to 35 days ex-factory, plus 25 to 35 days sea freight and a week or two for clearance and delivery. Order early, gates are a long-lead item that holds up the final fit-out.
Threadline sources the gate, motor, sensors, and access hardware from a single factory so it arrives as a pre-matched system, confirms the coating and electrical approval, and crates it properly for the trip.
