How to Properly Install Rectangular Aluminum Extrusions

Rectangular aluminum extrusions are versatile and durable building materials that can be used in a variety of applications, from framing to cladding. However, it is important to install them properly in order to ensure their performance and longevity. This article will provide a step-by-step guide on how to properly install rectangular aluminum extrusions.

Planning and Preparation

Before starting the installation, it is important to plan the layout of the extrusions and gather the necessary materials. The extrusions should be cut to the desired length and any necessary holes or notches should be made. The following materials are typically required for the installation of rectangular aluminum extrusions:

Extrusions

Fasteners (bolts, screws, rivets, etc.)

Sealant

Measuring tape

Level

Drill

Mounting the Extrusions

Once the extrusions have been prepared, they can be mounted in place. The mounting method will vary depending on the application, but there are two general methods:

Direct Mounting: The extrusions are directly attached to the substrate using fasteners. This method is typically used when the extrusions are used as framing or cladding.

T-Slot Mounting: The extrusions are mounted using T-slot fasteners that allow them to be easily adjusted or removed. This method is typically used when the extrusions are used as a structural support or as a component of a modular system.

Sealing the Joints

Once the extrusions have been mounted, it is important to seal the joints between them. This will prevent water and debris from infiltrating the structure and causing damage. The type of sealant used will depend on the application, but a silicone-based sealant is typically recommended.

Inspection and Maintenance

After the installation is complete, it is important to inspect the extrusions regularly and perform any necessary maintenance. This includes checking the fasteners for tightness, inspecting the sealant for damage, and cleaning the extrusions to prevent the accumulation of dirt and debris. By following these steps, you can ensure that your rectangular aluminum extrusions are properly installed and will provide years of reliable service.
