About System
Protect your trailer or camper from ugly scratches and dings
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?

“I was very pleased with the product and service. The price was the best I found, the shipping was fast, the diamond plate was packaged well (no damage in shipment), the material quality is good, it installed easily, and it looks good. All that should add up to a seven, but you only wanted a five!”

“We would rate our recent purchase from your company as a full "5". The diamond plate stone guard was competitively priced and we received it very quickly. It fit perfectly and the installation instructions were clear, concise and easy to follow. Best of all, the new stone guard made our rusty 1988 W-W stock trailer look presentable again. Thanks again for smooth transaction and we'll recommend your company to our friends.”

“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.”

“Five stars!!! I love this product and it was extremely easy to work with. I've never worked with metal before and cut this product very easily with a jigsaw. I now have the best looking horse trailer around and everyone agrees, thanks in part to the trailer stone guard. 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!”

“Still in the process of restoring my horse trailer, so haven't had a chance to put the gravel guard on quite yet. However, I can say that I'm excited to see the finished product! The trailer will be looking as good as new soon enough. Great website, awesome service, super fast shipping…excellent all the way around. Will definitely be recommending your products to others, and I'll be returning for some accents for the shop. Awesome stuff you have to offer! 5 stars, for sure. Thanks again!”
