Swing Gates — Your Guide to Making the Right Gate Choice
Welcome back to our gate automation series! If you’ve been following along, you’ve already explored the environmental fundamentals in Part 1 and automation considerations in Part 2.
Now it’s time to dive deeper into swing gate choice, popular for residential and commercial properties. Whether you’re leaning toward a single gate or considering a double setup, we’ll walk you through everything you need to know to make a smart decision.
Understanding Your Swing Gate Options
Swing gates are iconic for a reason. They’re intuitive, reliable, and work beautifully across a wide range of properties. But not all swing gates are created equal and the choice between single or double configurations can make a huge difference in how well your gate suits your space.
1. Single Swing Gates: The Standard Solution
Single swing gates are the workhorse of the automation world. They’re a popular choice and for good reason, they’re straightforward to install, easier to maintain and cost-effective compared to other options.
Single swing gates are ideal when you have:
– A driveway entrance that doesn’t require exceptional width
– Limited space on one or both sides for the gate to swing open
– A relatively lower traffic volume
– A standard residential or small commercial setting
The beauty of a single swing gate lies in its simplicity. It opens in one direction (typically inward depending on your preference and property layout) and the automation mechanism is straightforward to install and operate. If something goes wrong, there are fewer moving parts to troubleshoot.
However, consider your actual needs carefully. If you find yourself constantly wishing the opening was wider or if large vehicles struggle to squeeze through, you might regret not going with a wider system from the start.
2. Double Swing Gates: When You Need More Space
Double swing gates are your answer when a single gate simply won’t cut it. They swing open from both sides, with each leaf opening inwards. This caters for a much wider opening, which becomes critical when you’re dealing with:
– Wide commercial entrances or estates
– Large vehicles like delivery trucks or RVs
– Entrance is too large for single swing gates, (over 3.5m)
– Situations where you want a more balanced, symmetrical aesthetic
The trade-off? Double gates require more space on both sides of the entrance to swing fully open. You’ll also need two motors instead of one and the system is slightly more complex to install and maintain. But if your property can accommodate them, double swing gates provide a level of functionality and visual impact that single gates simply can’t match.
3. Motor Placement: Why 300mm Matters
Here’s where many people make their first mistake: undersizing the motor mount height. The industry standard is to mount the motors on the bottom rail of the gate. This can be as low as 50 – 100mm from the ground. Our recommendation is a minimum of 300mm (roughly 12 inches) above ground level.
Why? Think about what your motor experiences:
Rain and moisture splash up from the ground every time it rains or when you wash your driveway. A motor mounted too low will collect water and debris, leading to corrosion and electrical problems. Mounting at 300mm or higher keeps the motor out of the splash zone and dramatically extends its lifespan.
A higher mount absorbs some of that stress when the gate closes against a gate stop and distributes the pressures more evenly.
Accessibility for maintenance is another practical consideration. When technicians need to service or repair your motor, they’ll be grateful it’s at a reasonable working height rather than lying down at ground level.
Our recommendation? Aim for 400-500mm if your gate posts allow it. This gives you a safety buffer above typical splash zones and makes future maintenance far more convenient.
4. Wind Resistance: Closed in Gates vs. Open Balusters
Here’s a critical factor that surprises many homeowners: wind can be your swing gate’s worst enemy, but the impact varies dramatically based on your swing gate choice.
Solid or Closed in-Panel Gates
If you’ve chosen a gate with solid panels (wood, metal sheeting, or composite material), wind resistance becomes a significant concern. A solid gate essentially becomes a sail, the wind pushes against it with considerable force, placing massive stress on the motors, hinges and posts.
In areas with regular high winds or severe weather, a solid gate might experience:
– Increased motor strain and potential burnout
– Premature wear on mounts, hinges and moving parts
– Difficulty opening in extreme wind
– Risk of structural failure in storms
This doesn’t mean you shouldn’t choose a solid gate, many homeowners prefer the privacy and aesthetic they provide. Just go in with your eyes open. Typically upgrade the motor for a more powerful version.
5. Pipe Baluster or Louvre Design
Open design gates with pipe baluster or louvre construction are wind-friendly by comparison. Because air can flow through the gate rather than being stopped by it, wind resistance is dramatically reduced. This is especially valuable if you live in a coastal area, windy region or anywhere with seasonal storms.
The trade-offs are minimal: you may get less privacy and the open design might not suit your aesthetic preferences. But from a mechanical and durability standpoint, an open design gate will age far better in high wind environments.
If you live in a windy area and are torn between styles, this could be your deciding factor. A beautiful solid gate that fails during a storm is far more expensive than an open-design gate that keeps working year after year.
Posts: Where Strength Really Matters
This is the part that separates amateur installations from professional systems: everything ultimately rests on your posts and their foundations.
Why Strong Metal Posts Are Non-Negotiable
Your gate posts carry all the weight of the gate itself, all the stress from the motors opening and closing thousands of times per year and all the wind and weather forces we just discussed. Weak or wooden posts don’t get a second chance, they’ll bend, crack or fail and there’s no easy fix once that’s happened.
Use high-quality steel or aluminium posts, not timber or thin aluminium. Steel or aluminium posts should be:
– At least 100mm square for most residential applications
– 3mm thick for structural integrity
– Hot-dip galvanised to prevent rust in the ground
– Properly welded or reinforced bolting to any hinges or hardware
Skimping on post quality is one of the biggest false economies in gate automation. A $200 difference in post quality now will ensure your swing gate choice will align properly, automatically open and close without problems and save you thousands in repair or replacement costs later.
Solid Foundations: The Hidden Hero
Your posts are only as good as what they’re anchored to. Many gate failures trace back to poor foundations, not poor posts. Here’s what you need:
Concrete depth: Posts should be set in concrete that extends at least 700-900mm below ground level and 3oomm in diameter, depending on your soil type and climate. The longer the gate the deeper you need the concrete foundation.
Concrete quality: DO NOT USE QUICK SETTING PRE MIXED CONCRETE. Your posts will be carrying hundreds of kilograms of stress greater than any standard fence post. Premixed packs of quick set concrete are designed for ease of use. They never really mix properly in the hole and your weak concrete will settle, crack or fail over time. Mix your own builders mix and cement in a wheel barrow with a minimum of 6:1 ratio.
Post spacing in the concrete: The concrete should completely surround and encapsulate your post. Any gaps or air pockets are weak points waiting to fail. Allow concrete to cure fully (at least 4 days, preferably 7) before putting any load on the gate system.
Pro tip: If you’re replacing an old gate and the existing posts seem questionable, seriously consider replacing them too. Reusing weak posts will haunt you for years.
Putting It All Together
A swing gate choice for automation isn’t just about choosing single or double. It’s about understanding how every component from the motor height to the foundation depth work together to create a system that will serve you reliably for decades.
The three core principles to remember:
1. Choose your configuration (single or double) based on your actual space and future needs
2. Mount your motor properly 300mm minimum if practical but higher if possible. Make sure the motor mounts are solid.
3. Build for durability, strong posts set in solid foundations are your insurance policy against failure
