Aluminum Diamond Plate Sheet Metal 6 in x 120 in - 17 GA Thick Stone

Our review of this Aluminum Diamond Plate Sheet Metal focuses on practical use for trailers, RVs and campers; the bottom line is that installers and DIYers who need a corrosion-resistant, accurately sized stone guard will find it a dependable choice. The sheet arrives roll-packed with protective film on both sides, and the true 17 gauge base thickness delivers a noticeably solid feel compared with thinner hobby-grade plates. In this review the single biggest reason to buy is durability: the hot-rolled 3003 aluminum construction resists rust and stands up to rock impact and heavy foot traffic better than cold-rolled alternatives.

Key Features

• Material and finish: Hot-rolled 3003 aluminum provides enhanced corrosion resistance for outdoor and marine-exposed installations.
• True thickness: The sheet uses a real 17 GA 0.045 in base thickness, giving greater rigidity and long-term durability than many thinner plates.
• Deeper diamond pattern: The pronounced embossing improves slip resistance for ramps, steps and trailer floors.
• Roll-packed protection: Double-sided film and a careful rolling process reduce shipping creases and surface blemishes for a cleaner install.
• Installation kit: Each roll ships with pop-rivets and working gloves to simplify mounting and handling on site.
• Accurate dimensions: The listed 6 in x 120 in size matches installers expectations for consistent fit on common trailer and camper panels.

Who It's For

This plate is aimed at vehicle owners, fabricators and contractors who need a rugged stone guard or protective kick plate for trailers, RVs, campers and heavy-use vehicle floors. The combination of 3003 aluminum and 17 GA thickness makes it well suited where corrosion resistance and impact protection matter.

It is less appropriate for projects that require laser-thin, decorative trim or intricate metalwork where a lighter, more malleable sheet would be easier to cut and shape. Customers seeking pre-drilled or pre-formed panels should look for finished accessories rather than this raw sheet stock.

Pros & Cons

Pros

• Excellent corrosion resistance from hot-rolled 3003 aluminum for outdoor use.
• Solid, true 17 GA base thickness provides superior strength and durability.
• Deep embossed diamonds improve grip and lend a professional metallic appearance.
• Roll-packed with protective film and included rivets/gloves simplifies installation.

Cons
