Having everything ready will save time and ensure a smooth installation process.
Step-by-Step DIY Aluminum Fence Installation
Step 1: Plan and Layout Your Aluminum Fence
Proper planning is key to a successful fence installation. Follow these steps:
Mark the Post Locations
Use wooden stakes to mark the locations of end posts, corner posts, and gate posts. Run a string line between the stakes to create a straight line, which will guide you when digging the holes. (Refer to our Materials List for information on lines of fence NOT divisible by 6′).
Check for Utilities
Safety first! Before digging, Use your property’s plot plan to locate and mark any utilities like gas lines, water pipes, cables, drainage, or sewer lines. If the plan isn’t readily available, consult a local surveyor to avoid costly damage.
Measure Carefully
Use a layout guide to mark the placement of the post holes. Posts should be spaced 72.5″ apart (center to center). For gate openings, add 1/4″ to the width of single gates (e.g., a 36” gate requires a 36 1/4″ opening). For double gates, omit the additional 1/4″.
💡Pro Tip: Adjust your layout measurements for any sections of fencing that aren’t divisible by 6 feet. Some aluminum fence panels may need to be trimmed to fit properly.
Step 2: Dig the Post Holes
With your layout complete, it’s time to dig:
- Use a post-hole digger to drill holes; holes should be 4-6” wide and 24-42” deep, depending on your area’s frost line.
- As previously mentioned, space the holes 72.5 inches apart on-center for consistent panel alignment.
- Center each hole along the string line to ensure a straight fence.
💡Pro Tip: Use the layout guide provided by your aluminum fence supplier for accurate measurements specific to your aluminum fence styles.
Step 3: Install Aluminum Fence Panels and Posts
Now it’s time to set everything in place:
Attach the First Panel
Slide the notched rails of the fence panel into the corresponding holes on the post. Secure the panel to the post using 1” self-tapping screws.
Position the Post
Place the post into the first hole. Use a level to ensure it’s perfectly straight on two adjacent sides. Align the post with the string line for accuracy.
Secure with Concrete
Mix and pour concrete into the hole, leaving the top 2” unfilled. Fill the remaining space with compacted dirt for extra stability and press tightly to hold in place. If the concrete is too wet and the post has a tendency to dip down further, place a 2” block under the fence to keep it at the proper height. Install one post and panel at a time before moving to the next section.
Adjust as Needed
Once you’ve secured a section, ensure the posts align and follow the slope of the ground in your yard smoothly. Make adjustments before the concrete sets to maintain a consistent and polished appearance.
Repeat the process one post and one panel at a time for each section of your fence, following the string line closely for straight alignment.
Installing Your Aluminum Gate
With the fence panels and posts in place, it’s time to add the finishing touch—your aluminum gates.
Ensure Posts Are Stable
Ensure gate posts are fully set in concrete. Wait at least 24-48 hours after pouring the concrete.
Attach Hinges
Install the hinges on the gate frame (approximately 6” from the top and bottom) using the screws provided. Position the gate in the opening and secure one screw in each hinge. Use a helper to assist in holding it steady. Lastly, adjust as necessary before fully tightening all screws.
Finalize the Hinges
Once the gate swings freely above the ground and fits perfectly, add the remaining screws. Avoid adjusting the hinges, as they should be pre-calibrated for optimal function.
Install the Latch
Add the latch of your choice (we recommend a Magna latch for security and ease of use), ensuring it securely closes the gate. For double gates, attach a drop rod for additional stability.
💡Pro Tip: Minimize gate movement while the concrete is curing to ensure long-term durability.
Aluminum Fence Post Types
The image below illustrates the various post types mentioned in this guide.
DIY Installation Example
This step-by-step guide outlines the materials required and the precise process for installing your fence.
Materials Needed:
- End Posts (Quantity depends on total runs)
- Line Posts for every 6 feet of paneling.
- Corner Posts where lines meet at 90 degrees.
- Fence Panels: Preassembled 6-foot-wide sections.
- Gate Posts with thicker walls for added stability.
- Gate Hardware: Includes hinges, latches, and optional locks.
Step 1: Run A to B (10′ of Fence)
- Start at Point A with an End Post placed 2-3″ away from the house.
- Measure 10′ away from the house to Point B, a Gate End Post.
- Use 2 Fence Panels (6′ each). Panels are only available in 6′ widths, so round-up from the calculation (1.67 panels).
- Add 1 Line Post (number of panels minus 1).
- Add 1 Gate Post (similar to an End Post but thicker).
What you need for this section:
- 1 End Post
- 2 Fence Panels
- 1 Line Post
- 1 Gate Post
Step 2: Run B to C (Gate)
- From Point B to Point C, install a 4′ Wide Gate (measured from inside of one Gate Post to the other).
- Add 1 Gate Post.
What you need for this section:
- 1 Gate Post
- 4′ Wide Gate (includes hinges and latch; upgrades available like a lockable latch or heavier frame).
Step 3: Run C to D (9′ of Fence)
- Measure 9′ from Point C to Point D (a Corner Post).
- Use 2 Fence Panels (6′ each; one may need cutting for an exact fit).
- Add 1 Line Post.
What you need for this section:
- 1 Line Post
- 1 Corner Post
- 2 Fence Panels
Step 4: Run D to E (40′ of Fence)
- Measure 40′ from Point D to Point E (another Corner Post).
- Use 7 Fence Panels. Most panels will fit at full length; however, the last panel will likely need cutting.
- Add 6 Line Posts (panels minus 1).
What you need for this section:
- 6 Line Posts
- 1 Corner Post
- 7 Fence Panels
Step 5: Run E to F (42′ of Fence)
- Measure 42′ from Point E to Point F (a Gate End Post).
- Use 7 Fence Panels (no cutting needed as the length divides evenly).
- Add 6 Line Posts.
What you need for this section:
- 6 Line Posts
- 1 Gate Post
- 7 Fence Panels
Step 6: Run F to G (Gate)
- Between Point F and Point G, install a 3′ Wide Gate.
- Add 1 Gate Post.
What you need for this section:
- 1 Gate Post
- 3′ Wide Gate (with hinges and latch; upgrades available for locks, heavier frames, or arched designs).
Step 7: Runs G to J
- Follow similar steps as earlier runs (D to F and others) to determine the layout and materials for these sections. End at another Gate End Post.
Step 8: Final Run J to K (Double Gate)
- From Point J to Point K, install a 10′ Wide Double Gate. This can be two standard gates, two arched gates, or one large arched gate (a “Rainbow Gate”).
- Add 1 Blank Gate Post (this post has no holes for rails).
- Include a Drop Rod Assembly.
What you need for this section:
- 1 Blank Gate Post
- 10′ Wide Double Gate (with hinges and latch; upgrade options available)
- Drop Rod Assembly
Important Notes:
- Fence panels are always 6′ wide and may need cutting to fit exact measurements. This is common in runs like 9′ (C to D) or 40′ (D to E).
- Each post type has a specific purpose:
- End Post is used at the start of a fence run.
- Line Posts go between panels.
- Corner Posts are for turns.
- Gate Posts are for attaching gates.
Upgrade options include various aluminum fence colors and accessories, such as decorative caps, key locks, or arched designs.
Customize for Slopes: Racking vs. Stepping
If your fence runs along a slope, you’ll need to adjust how it’s installed. There are two methods to choose from:
Racking
This technique allows panels to follow the slope naturally. For gradual slopes, aluminum fence panels can “rake” to match the angle of the ground.
- Most aluminum fence styles rack up to 16 inches per 6-foot section.
- For steeper slopes, request “double-punched” panels that can rack up to 29 inches at no extra cost.
- Ideal for smoother, continuous lines without gaps under the fence.
Stepping
For steeper slopes, install the panels in a stair-step fashion. For specific styles, such as “Castle,” stepping may be preferred.
- This method involves creating a stair-step effect or tiered appearance by keeping panels horizontal and using brackets to accommodate the height changes along the slope.
- Perfect for properties where a stepped look complements the landscape.
Not sure which method to use? Contact your fence supplier for guidance tailored to your setup.
Residential, Commercial & Industrial Fence Grades

Frequently Asked Questions
Does DIY (Do-It-Yourself) mean that anybody can install it themselves?
We’d have to say no. The sections are pre-assembled, but if you don’t know how to dig 2′ deep holes with a 6″ diameter that are spaced 72.5″ on-center, then you should probably hire someone to do it for you.
Can the fence curve?
If your fence line curves, even though the sections don't bend, the sections can easily be angled in the posts up to 10 degrees per side of the post or 20 degrees if you turn the post 10 degrees first. This will follow most curves. For a very tight curve, just cut the sections in half and put another post between the two sections. The sections themselves cannot be bent without ruining their structural integrity.
How do I make a double-drive gate?
Any two gates can be combined to make a double drive gate that include a drop rod at no charge. Double gates are also made to fit a given opening size, so a 12’ double drive gate will fit inside a 12’ opening.
Do I need gate posts on both sides of a gate?
Yes, heavier posts are needed to both support the weight of the gate and to withstand the constant impact when the gate latch closes.
Having pool fences installed around your pool, whether it’s above-ground or below-ground, not only adds to the safety of your yard, but can also increase your property value should you ever choose to sell.
