Reinforced rub rails are an excellent addition to any dump trailer, providing extra protection against wear and tear while enhancing the trailer’s durability. These rails serve as a safeguard for the trailer’s sides, absorbing impacts from loading equipment, debris, and general usage. Proper installation ensures longevity and optimal performance. Follow these steps to successfully install reinforced rub rails on your dump trailer.

Step 1: Gather Tools and Materials

Before beginning the installation process, collect the necessary tools and materials. Having everything ready ensures efficiency and minimizes interruptions.

Tools Needed:

  • Measuring tape
  • Marker or chalk
  • Angle grinder or metal cutting saw
  • Drill and metal drill bits
  • Welding machine (optional but recommended)
  • Clamps
  • Socket wrench set
  • Safety gear (gloves, goggles, and hearing protection)

Materials Needed:

  • Reinforced rub rail sections (cut to size for your trailer)
  • Bolts, washers, and nuts (grade 8 or higher for durability)
  • Metal primer and paint (optional for rust prevention)
  • Protective sealant (if needed)

Step 2: Measure and Plan the Installation

Careful planning and accurate measurements are crucial for a proper fit.

  1. Inspect the trailer: Examine the sides of your dump trailer to identify the best mounting locations for the rub rails. Ensure the areas are free of dents, rust, or debris.
  2. Measure the trailer sides: Use a measuring tape to determine the length of each side where the rails will be installed. Mark the locations where the rails will begin and end.
  3. Plan for reinforcement points: Decide whether the rub rails will be bolted or welded. Bolting is more flexible for future replacements, while welding provides a permanent, seamless installation.

Step 3: Prepare the Trailer and Rails

Proper preparation ensures the rub rails fit securely and remain durable under heavy use.

  1. Clean the mounting area: Remove any rust, dirt, or debris from the trailer’s sides using an angle grinder or wire brush attachment. A clean surface is essential for secure mounting.
  2. Cut the rails to size: If the rub rails are not pre-cut, use a metal cutting saw to adjust them to the measured lengths.
  3. Drill mounting holes: If bolting the rails, drill evenly spaced holes along the length of the rub rails and the trailer’s sides. Use a drill bit slightly larger than the diameter of the bolts for easy alignment.

Step 4: Attach the Rub Rails

The method of attachment—bolting or welding—will depend on your tools and preference.

Bolting the Rub Rails:

  1. Align the rails: Position the rub rails along the marked installation points. Use clamps to hold them in place temporarily.
  2. Insert bolts: Insert bolts through the drilled holes, ensuring washers are placed on both sides for added stability.
  3. Secure the bolts: Tighten the nuts using a socket wrench, making sure the rails are firmly attached without overtightening.

Welding the Rub Rails:

  1. Position the rails: Align the rub rails with the trailer’s sides, using clamps to hold them in place.
  2. Tack weld the rails: Start with small tack welds at each end of the rail to ensure proper alignment.
  3. Complete the welds: Weld along the entire length of the rails, focusing on creating clean, continuous welds to prevent weak points.
  4. Grind and clean welds: Use an angle grinder to smooth out the welds and remove any sharp edges.

Step 5: Finish the Installation

Once the rails are securely attached, take steps to protect them and ensure a professional look.

  1. Apply a protective coating: Use a metal primer and paint to cover the rails and any exposed metal surfaces. This step prevents rust and corrosion, especially in harsh weather conditions.
  2. Seal the edges: If desired, apply a protective sealant along the edges of the rails to prevent moisture buildup.
  3. Inspect the installation: Check that all bolts are tight or that welds are smooth and secure. Ensure the rails are firmly in place without any gaps or loose sections.

Step 6: Test the Reinforced Rub Rails

Before putting the trailer into full use, test the new rub rails for durability.

  1. Inspect for movement: Push or pull on the rails to ensure they are secure.
  2. Simulate impact: Gently tap the rails with a hammer to check their ability to withstand minor impacts.
  3. Load and unload: Test the trailer with regular operations, such as loading and unloading heavy equipment or materials, to confirm the rails function as intended.

Tips for Long-Term Maintenance

To maximize the lifespan of your reinforced rub rails:

  • Regularly inspect the rails for signs of damage or wear, such as dents or loose bolts.
  • Keep the rails clean by washing them after heavy use, especially if exposed to corrosive materials.
  • Touch up paint or sealant as needed to prevent rust and corrosion.

Conclusion

Installing reinforced rub rails on a dump trailer is a practical way to protect its sides from damage and extend its lifespan. By following these steps and maintaining the rails properly, you can ensure your dump trailer remains functional and visually appealing for years to come. Whether you choose to bolt or weld the rails, the key is a secure and precise installation that meets the demands of heavy-duty use. For professional help, we recommend Grizzly Trailer Sales.
