Protect your trailer with our stunning Stone Guard MX™. Crafted from real 17GA (0.045"tk) Commercial Grade Aluminum Diamond Plate – not the imitation 22GA (0.025"tk) stamped pot metal that others use – so be sure you're getting your money's worth. Available in any size you need up to 4'x10' and ships conveniently via FedEx Ground so you save on shipping cost. Beautiful, high-polished, chrome-like shine and World Exclusive anodized colors will turn your trailer into a stunning machine. Trailer Stone Guard MX™ is flexible so it’s easy to flex around curves and bends. Will not peel, flake or corrode. Stands up to heavy duty abuse. Easy to cut, drill, form around radius corners by hand, etc. Diamond Plate is also known around the world as tread plate and checker plate.
Our diamond plate is absolutely, authentic, real commercial grade aluminum diamond plate. The same brilliant metal found on big rigs, NASCAR, fire trucks and other astonishingly cool objects and cool places. Not to be confused with imitation stamped metal that many of others use. Our real diamond plate will not rust, rot, corrode or degrade.
How can you tell the difference between real diamond plate and the fake stuff? The secret is on the backside of the metal. The diamonds on real diamond plate are forged from solid metal and therefore are perfectly solid when viewed from the back. Fake diamond plate is stamped from sheet metal producing diamonds that are hollow on the backside making the fake stuff weak, feeble and less desirable. Real diamond plate has a beautiful chrome like metallic luster. The fake stuff can fake the shine but can't fake the strength of real diamond plate. They say diamonds are a girl's best friend... but who wants hollow diamonds?

“It arrived in great shape. I used my old ugly gravel shield as a template and it fit perfectly. It took only about an hour to install. I used double faced tape to hold it in place while I installed the screws. Overall very easy installation. I'm very pleased with the quality and price.”

Here's a pic of the before and after and you can see the diamond plate finishes it off perfectly!!!! It's functional meets finish!”
