How to Choose the Right Sliding Gate for Your Property

Thinking about installing a sliding gate to update your entrance, save space, or improve security? This guide walks you through how to measure for a sliding gate step by step, highlights common mistakes to avoid, and helps you select the best option for your outdoor space.

1. Measure the Width Between the Posts

Measure the inside distance between your two gate posts at three different heights:

A
Top
B
Middle
C
Bottom

Why three measurements? Posts may not be perfectly parallel—especially on older installations or if they've shifted over time.

Record the smallest of the three measurements—this is the usable width for your sliding gate.
If the difference between measurements is more than 1/2 inch, check the alignment of your posts before installing. For example: If you measure 119.3" at the top, 118.5" in the middle, and 118.9" at the bottom, use 118.5" as your reference width.

2. Measure the Height from the Ground to the Bottom of the Post Cap

Next, measure the total height available from the finished ground level up to the underside of the post cap (or cover).

  • • Take this measurement on both sides, as the ground may slope slightly.
  • • The final gate height should be 2–4 inches less than the available height to allow for hardware clearance and smooth operation.

Make sure the rack and motor (if using automation) will fit without interfering with the gate height.

3. Plan for Side Clearance

A sliding gate opens to the side, so you’ll need enough space on one side of the opening.
Clearance = gate width + at least 20 inches.
This extra space is needed for the rack, motor (if automated), and end stops.

4. Check Ground Level and Alignment

Before installing a sliding gate, make sure the ground is level and solid. If the surface isn’t flat, the gate may drag, get stuck, or wear out faster.
The base should be firm, without holes or bumps—even small uneven spots can cause issues. If needed, pour a straight concrete pad (called a threshold) along the full width of the opening.

If your driveway slopes, consider a cantilever gate (which doesn’t require a ground track) or adjust the concrete to create a level base. Before installation, always check with a laser or bubble level to confirm everything is straight—this ensures smooth operation and long-lasting performance.

Summary:

Measure the width between posts at the top, middle, and bottom. Use the smallest value.
Measure the gate height from the ground to the post cap.
Allow for side clearance at least equal to the gate width plus 20 inches.
Check that the ground is level and stable. If not, install a straight concrete threshold.

If you’re unsure, contact a professional for on-site measuring—this is the best way to ensure a perfect fit.

How do I install a sliding gate kit? +

To install an aluminum sliding gate kit, start by preparing a level foundation. Secure the guide rail onto the concrete base, set the guide posts in place, and fit the end stops. Our detailed installation guides walk you through each step, making the process straightforward even if you're new to DIY projects.

How do I maintain a sliding aluminum gate? +

Maintaining a sliding aluminum gate is straightforward and requires minimal effort. Clean the gate twice a year using warm soapy water and a soft cloth, then rinse with clean water. Regularly check the guide rail and remove any leaves or debris to ensure smooth operation. It's also a good idea to lubricate the moving parts once a year to keep your gate in top condition.

Can the gate open both ways and be motorized? +

Our aluminum sliding gates kits are designed for smooth manual operation, allowing you to open the gate to the left or right depending on your setup. The lightweight aluminum makes daily use easy, even without a gate opener. If you prefer, you can add a motor later—our sliding gate kits are compatible with automation systems for added convenience.

What are the drawbacks of an aluminum gate? +

While aluminum gates offer many advantages, there are a few factors to consider before making your purchase. The initial cost is generally higher than PVC gates, though this can be offset by aluminum’s impressive lifespan.

For sliding gate models, your outdoor space needs enough room on one side to allow the gate to open fully. This requirement can be a challenge if your driveway or entrance is narrow.

Dimensions may also require adjustments. If your property is on a steep slope, installing the guide rail may involve extra leveling work. Additionally, because our gates are fully welded for strength, it’s not possible to replace individual sections if they’re accidentally damaged.

What is the average price of an aluminum gate? +

Standard swing aluminum gates start at around $700, while sliding models typically begin at $1,000. The higher price for sliding gates is due to the more complex sliding mechanism and the tracks required for installation.

Our DIY gate kits are a great way to save on costs. Assembling the gate yourself helps you cut down on labor expenses, while still enjoying the premium quality of aluminum. Gates are available in several colors, including anthracite gray and white, at no extra charge.

Scheduled delivery makes it easy to receive your gate at home. The final price will depend on the size, optional motorization, and finish you select. Our range is designed to fit a variety of budgets and provide a long-lasting solution for your property.
