Guide To Installing Aluminum Diamond Plate In Truck Bed

As a truck owner, it’s normal to experience issues as your truck starts to age. But don’t worry, there’s a solution that can breathe new life into your truck and give it a fresh, young look. The answer to your problems is the aluminum diamond plate, a product that not only enhances the appearance of your truck bed but also offers numerous benefits.

If you’re considering buying an aluminum diamond plate for your truck bed, my advice is that you’ll be making the best choice for circumstances where both durability and appearance are important. The diamond plate provides optimal protection for your truck bed rails, caps, bulkhead, and tailgate from dents, scratches, and dings when hauling anything with your truck.

The diamond-plate finish is widely popular among truck and trailer owners, and it’s easy to see why. It offers advantages such as rust and corrosion resistance, protection from all forms of damage, added strength and durability, and a stylish touch to your truck. These benefits make the aluminum diamond plate a great investment for any truck owner who wants to keep their vehicle looking great for years to come.

How To Install Aluminum Diamond Plate?

The safety of those using your truck bed is of utmost importance, which is why proper installation of the flooring is a critical step. To ensure a safe and secure surface, it’s important to check for uneven areas, raised edges, sharp corners, and loose surfaces.

  • Before you begin, make sure you have the correct measurements for your truck bed. Carefully measure the length and width, and transfer those measurements to the back of the diamond plate. The raised patterns on the diamond plate metal make the back the best place to use a marker for your measurements.
  • Using a wood cutting saw that is appropriate for cutting aluminum is the easiest and most accurate method. Be sure to sand any sharp edges and burs to avoid any injury or unsightly appearance. To secure the diamond plate, drill evenly spaced holes along the edge, approximately every 10 inches or adjusted to your truck bed’s size or shape. A ¼ inch diameter drill bit is a good start.
  • Once the holes are drilled, place the diamond plate over the surface and mark the holes on the existing surface. Then, drill holes in the existing surface for easy installation. When using a ¼ inch drill bit, use ⅛ inch self-tapping metal screws. These screws are designed to tap their own mating thread into the surface, ensuring a secure hold. With these steps in mind, you can ensure that your aluminum diamond plate installation is both safe and correct.

Mistakes to Avoid During Installation

When installing an aluminum diamond plate in your truck bed, it’s important to avoid some common mistakes to ensure the best results. Here are some common mistakes to be mindful of:

  • Improper measurement: Not accurately measuring the length, width, and shape of your truck bed before cutting the diamond plate can lead to an improper fit and wasted material.
  • Cutting the diamond plate with an inappropriate saw: Using a saw that is too small or not designed for cutting aluminum can result in jagged edges and an overall poor finish.
  • Neglecting to sand sharp edges: Sharp edges can be dangerous and unsightly. Make sure to sand down any sharp edges or burs to ensure safety and a polished look.
  • Drilling holes too close or too far apart: Incorrectly spaced holes can lead to a less secure hold and potential damage to the truck bed.
  • Not using self-tapping metal screws: Self-tapping metal screws are specifically designed for metal surfaces and provide a secure hold. Using a different type of screw can result in a less secure installation.
  • Not drilling holes in the right place: Make sure to mark the holes on the existing truck bed surface before drilling to ensure they are in the right place.

By avoiding these common mistakes, you can ensure a safe and successful installation of your aluminum diamond plate in your truck bed.
