About Inside Corner Trim molding

a drawing of Aluminum inside corner trim dimensions and sizes

Our aluminum inside corner trim molding can help to achieve a clean finished look to your diamond plate wall panel project.  For example, they work by allowing you to hide the edges of your diamond plate sheets where they meet at the inside corner of a wall.   Additionally, these moldings are 100% aluminum and have a beautiful finish.

As an added bonus, the use of these moldings can help to streamline the installation of diamond plate wall panels.

Inside corner trim molding finishes the inside corners of a diamond plate wall panel installation.  Use inside corners where two diamond plate sheets meet at a 90 degree angle.

We recommend using one Inside corner molding at every 90 degree inside corner where one panel meets another.  By doing so, you will accomplish a professional looking installation of diamond plate.

How to install Inside corner molding .

To install these aluminum inside corner trim moldings, First,  We recommend that you plan your install ahead of time because the trim moldings have to be installed in a specific order.  For instance, a typical installation will start at one corner with an inside corner trim molding, followed by the diamond plate sheets and h-seam moldings for the first wall.  The final sheet of diamond plate on the first wall should fall to within 1/4″ or less to the next wall.

The installation of the wall perpendicular to the first wall starts with an inside corner trim molding. The corner trim conceals the gap in the corner, and will begin your next wall run.

Each job will have different requirements that should be considered when planning how to install the inside corner trim moldings.

Aluminum inside corner trim molding is a very good alternative to using other inside corner trim methods. Additionally, the extrusions have been custom made to match our .025″ aluminum diamond plate wall panel finishes. We recommend using the inside corner trim molding on jobs that require the most professional look and finish.  Install inside corner trim over the top face of diamond plate wall panels to hold them in place.
