Step 1: Introduction to the Composite Fence

The composite fence system is designed to blend exceptional durability with modern aesthetics. This system features aluminum channels and posts that create a strong, long-lasting structure. Customers can personalize their fence with options for gap designs, solid panels, or multi-color setups, ensuring it complements any outdoor space.

The tongue-and-groove (TNG) composite boards are engineered for strength and longevity. These boards are resistant to water damage, termites, and other common problems found with traditional wood fences. Plus, they’re virtually maintenance-free—simply rinse them with water to keep them looking new.

This cutting-edge design provides a sleek, modern look while ensuring years of reliable performance, making it the perfect choice for homeowners and contractors alike.

Step 2: Setting a Strong Foundation for Your Fence

The foundation is the backbone of a durable fence, and the composite fence system ensures a solid start. Begin by cementing a steel post (1 1/4 inch in diameter) into the ground. This provides a sturdy base for the fence.

Once the steel post is set, slide the pre-cut aluminum post sleeve over it. If the fit is tight, use a rubber mallet to gently tap it into place until it’s secure. After the aluminum post is properly positioned, attach the first bottom channel to the post. At this stage, there’s no need to level it, as this can be done later in the installation process.

By following these steps, you establish a strong, reliable foundation for your fence.

Step 3: Installing the Base Rail and First Composite Board

With the foundation in place, it’s time to begin assembling the fence. Start by attaching the first aluminum rail at the base of the post. This rail serves as the structural guide for the fence panels above it.

Next, insert the first pre-cut composite board into the channel of the rail. Ensure that the board fits snugly into the groove, creating a secure and level connection. Take care to align the board properly, as this will set the tone for the rest of the installation.

Once the board is securely placed, you’ve successfully started the process of building a strong and visually appealing fence.

Step 4: Alternating Channels and Boards for a Seamless Build

After the first board is securely installed, the next step is to build the fence by alternating aluminum channels and composite boards. Begin by sliding the next aluminum channel into place over the top of the previously installed composite board. The channels are designed with a "T" profile that perfectly complements the tongue-and-groove edges of the composite boards, ensuring a snug and secure fit.

Once the channel is in position, add another composite board, sliding it into the groove of the channel. Repeat this process, stacking the boards and channels alternately, until the desired fence height is achieved. This modular system allows for a quick and efficient assembly, while also maintaining structural integrity and a seamless appearance.

By following this step, you’ll see your fence taking shape, one level at a time.

Step 5: Installing the Top Rail for a Polished Finish

The final structural step is to install the top rail, which provides both a polished appearance and enhanced durability for your fence. The top rail is a solid aluminum piece, designed to cap off the fence with a clean and professional finish.

Carefully position the top rail over the last composite board and ensure it aligns perfectly with the rest of the fence. The solid construction of the top rail not only adds aesthetic value but also reinforces the structural integrity of the fence, making it resilient against wind and other external forces.

Once the top rail is securely in place, your fence will have a sleek, modern look that enhances the overall appeal of your outdoor space.

Step 6: Repurposing Leftover Fence Materials into a Durable Planter

One of the benefits of working with Alu Globus composite fence materials is their versatility, even for leftovers. Instead of discarding unused aluminum or composite pieces, you can repurpose them to create a 100% rust-free, durable planter.

To make a planter, use the leftover aluminum channels and cut-off pieces of composite boards. Assemble them into a box-like structure, ensuring that the aluminum provides a sturdy framework. This project not only reduces waste but also adds a functional and aesthetic element to your outdoor space.

The resulting planter is not only eco-friendly but also highly durable, capable of withstanding outdoor conditions without rusting or degrading. It’s a practical and stylish way to make the most of your materials.

Step 7: Adding Finishing Touches for a Professional Look

The final step in installing your composite fence is to add the finishing touches that ensure a clean and professional look. Begin by covering any gaps with post covers, which are designed to conceal the steel and aluminum framework for a seamless appearance.

Next, add caps to the aluminum channels. These caps not only enhance the aesthetic appeal but also provide additional protection to the structure. To further improve durability and weather resistance, use silicone to seal the edges, preventing moisture or debris from getting inside.

If any of the cuts are slightly uneven, don’t worry. The combination of caps and covers will hide imperfections, resulting in a polished and cohesive finish. This attention to detail makes your fence look expertly installed, even if it’s a DIY project.
