Aluminum Diamond Plate Sheet Metal 5 in x 120 in - 17 GA Stone Guard

Our review of this Aluminum Diamond Plate Sheet Metal focuses on who will get the most value from a heavy-duty, corrosion-resistant metal panel. The sheet is clearly aimed at owners of cargo trailers, RVs, campers and workshops who need a reliable stone guard or skid surface; the single biggest reason to buy is the use of 3003 hot-rolled aluminum with a genuine 17 gauge base thickness, which delivers noticeably greater corrosion resistance and structural stability than typical cold-rolled sheets while keeping the finish usable for exterior applications.

Key Features

• Material: 3003 hot-rolled aluminum offers improved corrosion resistance for outdoor and marine-facing installs.
• True thickness: The sheet uses a real 17 gauge (3/64 in) base thickness for extra rigidity and durability in high-wear panels.
• Embossed pattern: Deeper diamond pattern gives enhanced slip resistance on steps, ramps and trailer beds.
• Shipping and handling: The roll-packed design with double-sided protective film reduces shipping creases and surface stains during delivery.
• Installation extras: Each roll ships with pop rivets and gloves to speed basic mounting and handling.
• Finish: Sleek metallic texture maintains a clean appearance while resisting rust and common outdoor deterioration.

Who It's For

This product is best for DIYers and tradespeople who need a durable stone guard or rock guard for trailers, campers and RV lower panels, and for shop owners installing non-slip flooring in light commercial settings. The heavier 17 gauge base is suitable where long-term durability and resistance to salt or road grime matter.

Those who primarily need ultra-lightweight trim pieces, decorative panels with no structural demands, or custom-formed architectural cladding should consider thinner or specialty aluminum options instead; this sheet is optimized for protection and wear rather than purely decorative, easily bendable uses.

Pros & Cons

Pros

• Real 17 gauge base thickness provides solid rigidity and a long-lasting protective surface.
• 3003 hot-rolled aluminum improves corrosion resistance compared with common cold-rolled sheets.
• Deeper diamond embossing increases grip and gives a modern, durable look.
• Roll-packing with protective film and included rivets simplifies initial installation needs.

Cons

• Heavier gauge and deeper pattern make cutting and laying the sheet more demanding for casual users.
• Rolled packing reduces creases but some flattening or use of a roller/heat gun may be needed for a perfectly flat finish.

Frequently Asked Questions

Is the thickness listed the full pattern height?
The 17 gauge refers to the base thickness (3/64 in) and does not include the embossed pattern height.

Will it arrive flat or rolled?
The sheet is roll-packed to avoid deep creases; light rolling or a heat gun can help flatten the sheet if needed for installation.

Does it include hardware for mounting?
Yes, each roll ships with pop rivets and a pair of working gloves to assist initial installation.
