Introduction to the Contractor Line

 

All Al Globus welcome to the channel! We’re assembling our contractor line, which a DIYer can also use, but it’s engineered for contractors. This system is super durable, designed to withstand tough conditions. You’ll be securing your screws directly into the flat, ensuring the fence is solid and won’t go anywhere without relying on brackets. We work with a ¾ gap for optimal spacing.

Aluminum Fence Installation: A Complete Guide

Short answer: A DIY aluminum fence goes up in 3 main steps: set the posts in concrete about 24 inches deep, level them, then slide the slats into the posts from the top slat down.

If you’re considering a new fence, aluminum fence installation is one of the smartest choices for homeowners. The process is straightforward, cost-effective, and results in a long-lasting barrier that looks sleek and modern. Unlike wood or iron, aluminum panels are pre-engineered with powder-coated finishes and modular components, which makes installation faster and easier without the need for welding or heavy tools.

The first step in aluminum fence installation is setting strong posts in concrete. Once the posts are secure, the panels or slats slide directly into the channels, locking into place for a tight, professional finish. Even on sloped yards, aluminum panels are designed to “rack,” which means they adjust to uneven ground without leaving gaps.

Another advantage of aluminum fence installation is its speed. A standard team can complete an average-sized yard in just one or two days, while DIY homeowners can also achieve great results with basic tools like a level, drill, mallet, and measuring tape. The result is a rust-proof, maintenance-free fence that adds security, style, and long-term value to your property.

Before You Start: Utilities, Tools and Fence Layout

Short answer: Call 811 (the free U.S. call-before-you-dig line) before you dig, mark the fence line with string and stakes, and space 2″ posts 72½″ apart center to center (73″ for 2.5″ posts) so standard 6 ft panels fit.

Quick overview

  • Estimated install time: 1–2 days
  • Tools needed: drill, post hole digger, level, concrete, measuring tape
  • Panel spacing: 72.5″ for 2″ posts, 73″ for 2.5″ posts
  • Permits: many cities and HOAs require a permit for a new fence, so check local zoning first (see our California fence permit guide).

Check for underground utilities

Before you break ground, make sure there are no cables, pipes or other utilities where you will dig:

  • Call 811 a few days before you dig so the utility companies can mark underground cables and pipes, or call your local utility companies directly. Contact both the water and the electricity provider, as they may be separate in your area.
  • Contact your local health department to find the location of septic lines.
  • Call your local government if you are unsure which agencies manage certain utilities. They can also tell you the zoning rules.
  • If you are still unsure, a land surveyor can locate utilities, drainage and sewer lines before you start digging.

Gather the right tools

  • String and wooden stakes to mark the fence line.
  • Post-hole digger (manual for small projects; an auger, often available to rent, for larger ones) and a shovel.
  • Level and measuring tape for straight, evenly spaced posts and panels.
  • Concrete to anchor the posts. It lasts longer than gravel.
  • Cordless drill or impact driver. A magnetic bit holder helps you avoid losing screws.
  • Optional: a digging bar for hard ground and a rubber mallet to tap posts into place without damage.

Mark and lay out your fence line

Set stakes at the end and corner posts first, then stretch string between them to make a straight guideline. Mark each post position along the string: 72½″ center to center for 2″ posts (the standard spacing for 6 ft panels) or 73″ for 2.5″ posts.

Cut a panel to fit if needed

Not every run divides evenly into 6 ft sections. Measure the length you need and add ¾″, because ¾″ of the panel sits inside the post. Mark the cut on the rails with a silver marker (easy to see on black aluminum) and cut with an angle grinder and metal cutting wheel, or a hacksaw. Always wear safety glasses and ear protection.

Keep the screw side facing in

When you attach panels to posts, face the screw side of every panel inward. The outside of the fence stays clean, and the whole run looks consistent.

Team Installation Process

Short answer: Two people install an aluminum fence much faster than one: one holds and levels the posts and slats while the other fastens them.

 

Working as a team makes the job much easier and faster. While it is possible to install the fence solo, doing it alone will not only take much longer but also might cause unnecessary frustration and errors. Having a team to assist with the installation process can save significant time, reduce mistakes, and ensure the overall stability of the fence. Working in tandem also allows you to handle the heavy lifting of posts and slats while maintaining the precision needed for a solid, long-lasting installation.

post and slat setup | Step-by-Step Aluminum Fence Installation for DIYers | Aluglobusfence.com

Method 1: Tapping Screws into Each Slat

 

In this method, screws are tapped into each slat, securing each slat individually to the posts. This technique ensures that each slat is firmly attached, offering additional stability to the entire structure. This method is ideal when you’re looking for a more secure and durable fence, particularly in areas prone to wind or where extra stability is needed. It also creates a clean, uniform look across the slats, with each one being held tightly in place.

Method 2: Tapping Screws into Top and Bottom Slats Only

 

This installation method is less time-consuming and allows for more flexibility, especially when working with a larger fence. By tapping screws only into the top and bottom slats, the middle slats remain free within the post channels, which can make the entire installation process faster. To keep the middle slats from shifting, you’ll need to use spacers to maintain consistent gaps between them. For additional help, check out our expert DIY installation tips.

Setting Up Posts and Aligning the First Slat

Short answer: Set each post in a concrete footing at least 24 inches deep, check it is plumb, and align the first slat at the top before adding the rest.

First, set your posts in concrete, level them, and align your first slat at the top. This ensures that your line is straight and professional-looking. From there, you can continue installing the slats. The slats slot into the channels and remain secure. Our fence hardware line is fully aluminum, 100% made and powder-coated in the U.S., offering endless color options to suit your preferences. For detailed guidance, visit our installation overview.

Durable Features of the Contractor Line

Short answer: The contractor line has a breaker point in the middle of the run, so the slats will not buckle, backed by a lifetime guarantee against buckling.

 

We’ve designed our aluminum system with a breaker point in the middle to maintain stability and prevent buckling. Rest assured—our slats will never buckle, and we offer a lifetime guarantee against it. The robust construction is made to last, whether you’re a professional contractor or a DIY enthusiast.

Installation of Stainless Steel Components

Short answer: Use only the stainless steel hex screws supplied with the system, which comes in 6 ft and 18 ft lengths, so no fastener will rust.

Our system uses high-quality hex screws and stainless steel components. We understand that rust can ruin your beautiful fence, so we ensure every part is corrosion-resistant. This system comes in 6 ft and 18 ft lengths and is excellent for use as wall toppers or privacy fences.

Customizing the Fence for the Perfect Fit

Short answer: If the last slat does not fit at the bottom, finish the run with a narrower end slat or trim a slat to size for an exact fit.

 

Many clients ask what happens if the last slat doesn’t fit perfectly at the bottom. The solution is simple: purchase our smaller slat to finish with a perfect fit. This gives you the flexibility to achieve the precise dimensions you need, even if the final slat is slightly different.

Efficiency of Installation

Short answer: Once the posts are set and cured, the slats slide in quickly, so most of the time on a DIY aluminum fence goes into setting and leveling 1 post at a time.

 

Once your posts are set, the fence won’t budge. We had two panels up in just 20 minutes after pouring the concrete. Installation is quick and easy, and if you need to make adjustments, simply remove the screws or spacers depending on your setup. Aluglobus contractors and DIYers alike will appreciate the efficiency and durability of our system. Return to the homepage to explore more options.

ALU60 Slat Horizontal Fence: Step-by-Step

Short answer: Set the posts, fit the bottom rail level, slide the boards in, add stoppers if you want gaps, fasten the frame, snap on the gap closer and finish with the top rail and post cap.

This is the same horizontal fence built with the ALU60 Slat system, where the boards slide into the post channels without screws.

Step 1: Set up your posts

Short answer: Set each post at least 24 inches deep in concrete, plumb it on 2 sides, and let it cure before you add rails or boards.

  • Measure and mark each post position, allowing for any change in ground level.
  • Align the three-way post at the correct height with a laser or bubble level, checking both directions.
  • Mounting on concrete or brick? Pre-drill pilot holes and use masonry screws or anchors.
  • Check for level again. An out-of-level post makes the whole fence look uneven, so brace it with temporary supports while it sets.

Step 2: Install the bottom rail

Short answer: Fasten the bottom rail level between the 2 posts first, because every board above it rests on this rail.

  • Slide the bottom rail in so it sits flush between the posts or wall extrusion.
  • Secure it with screws. Over soft ground, drive small stakes underneath for extra support.
  • Check that it is level. If it is off, every slat above it will be off too.

Step 3: Slide in the fence boards

Short answer: Slide the boards down into the post channels one at a time. The boards themselves need no screws.

  • Start each board at a slight angle so it drops smoothly onto the bottom rail.
  • Press down lightly so it seats fully, then add the next board snug against it.
  • In hot weather, leave a 1/16″ gap between boards for expansion.

Step 4: Create a privacy gap (optional)

Short answer: For airflow or a modern open look, set an even gap between boards instead of stacking them tight for full privacy.

  • Use the stoppers (spacers) to set 2″, 1″ or custom gaps.
  • Insert them at regular intervals so every board sits evenly.
  • Step back and check the gaps are uniform before you continue.

Step 5: Secure the fence to the wall or post

Short answer: Screw the rails and end boards to each post or wall with stainless steel fasteners so the run cannot sag or shift over time.

  • On concrete or brick, fix the wall extrusion with expansion anchors.
  • Fasten to the posts with corrosion-resistant screws.
  • Give the frame a shake. If anything moves, tighten the connections.

Step 6: Install the gap closer and hide the screws

Short answer: Snap the gap closer over the post channel to cover the screws and give the fence one clean, finished face.

Press the gap closer firmly until it clicks into place, then slide it so it sits flush.

Step 7: Install the top rail and finish

Short answer: Fit the top rail last to lock all the boards in place and give the fence a finished top edge.

  • Slide the top rail in so it fits snugly between the posts, then screw it down.
  • Install the post cap for a clean, modern finish.

Questions buyers ask

Quick answers on installing an aluminum fence yourself. Every answer is shown; tap a question to fold it away.

Can I install an aluminum fence myself?

Yes. Aluminum fences are one of the easiest fencing systems for DIYers to install. With a pre-engineered Aluglobus kit you set the posts, slide the slats into place and secure the panels with basic tools, with no welding or cutting required. A second person makes the job faster and helps keep posts level.

How do I secure aluminum fence posts?

Set aluminum posts in concrete footings for maximum stability. Dig each hole at least 24 inches deep, level and plumb the post on two sides, and let the concrete cure fully before you attach any slats. Where you have an existing slab, surface-mount the posts on base plates instead.

Can I install aluminum fencing on a slope?

Yes. Aluminum fencing can go on a slope by racking, where the slats follow the grade, or by stepping, where each panel stays level and steps down the hill. Aluglobus slats work with both methods, so you can choose based on how steep the terrain is and the look you want.

How do I keep the slats from shifting?

Use spacers between the slats. If only the top and bottom slats are screwed to the posts, spacers keep every slat aligned and stop movement over time. Aluglobus section kits include the spacers for the gap size you order, so the fence stays straight and evenly spaced for years.

Is aluminum fencing rust-proof?

Yes. Aluglobus aluminum fence kits use powder-coated aluminum and stainless steel screws, so they will not rust, even in coastal or humid climates. Aluminum forms its own protective oxide layer, and the powder coat adds a durable color finish that only needs an occasional wash with water and mild soap.

What if the last slat does not fit perfectly?

Finish the run with a narrow end slat. Aluglobus offers narrower slats for a clean last row, and you can also trim a slat to fit your height or ask our team for custom sizing. This keeps the bottom gap even and gives a seamless look along the whole fence line.

Can aluminum fences be used as privacy fences?

Yes. Tongue-and-groove aluminum slats such as ALU50/60 interlock with no gap for full privacy, and you can also combine aluminum frames with composite inserts. The Aluglobus system supports both open slat styles and solid privacy panels, so you can pick the level of privacy each side of your yard needs.
