Installing corner aluminum extrusions requires meticulous attention to detail to ensure a sturdy and aesthetically pleasing finish. These tips will guide you through the process step by step, ensuring a successful installation.

Cutting and Prepping

1. Measure and mark the desired length on the extrusion. Use a miter saw equipped with a fine-toothed blade to achieve precise cuts.

2. Deburr the cut edges using a file or sandpaper to remove any sharp burrs or imperfections.

3. Clean the extrusions and the installation surface with a degreaser to remove any oils or debris.


1. Apply a thin bead of construction adhesive along the inside corners of the extrusions.

2. Position the extrusions perpendicular to each other and press them firmly into place.

3. Use a level to ensure that the extrusions are aligned vertically and horizontally.


1. Use self-tapping screws or rivets to secure the extrusions to the installation surface.

2. Space the screws or rivets evenly along the length of the extrusions, approximately every 12 inches.

3. Check the tightness of the screws or rivets periodically and tighten them if necessary.


1. Apply a bead of silicone caulk along the seams where the extrusions meet.

2. Use a putty knife to smooth the caulk and remove any excess.

3. Allow the caulk to cure according to the manufacturer’s instructions.

Additional Tips

Wear gloves and safety glasses during installation to prevent injury.

Use a sharp blade and cut slowly to minimize burrs.

Allow the adhesive to fully cure before applying any weight or pressure on the extrusions.

If the extrusions are exposed to the elements, apply a protective coating or paint to prevent corrosion and weathering.
