Guidelines, Applications and Questions for the Different Thickness of Aluminum Diamond Plate

0.032″ and 0.045” thickness black diamond plate are both thick and strong, making it perfect for all applications.

0.063 thickness diamond plate is a good thickness which can be used for covering walls and lightly used floors. It’s thick enough to take a lot of wear and tear for any wall. Some clients use it for covering the floors which are not heavily used.

It’s great for :

  • covering walls
  • back splash
  • fitness room/gym
  • garage
  • shelves or shelf front covering
  • displays
  • stone guard for horse/animal trailers
  • trailer
  • art project
  • cars/trucks
  • easy to be bend around the corner in protecting the worn of wall
  • door guard and kick guard
  • wall border base board
  • ceiling
  • trucks trims

Aluminum is light, soft and remarkable for its ability to resist corrosion

Most of aluminum diamond plate are made with 3003 aluminum alloys strengthened with Manganese.

Hot-rolled diamond plate materials are generally better than cold-rolled diamond plates because hot-rolled materials have uniform microstructure with less defects and cracks.

Cold-rolled material has a lot of micro-defects and cracks resulting in the tendency to crack when bending. All of our products are hot-rolled for maximum product quality.

The best about aluminum diamond plate is that you can cut it relatively easily.

Generally, a wood saw or metal saw will work fine with cutting.

You can easily drill through these aluminum diamond plate easily with regular drills

These materials are typically used for both industrial and domestic purposes due to their high strength and low cost, combined with malleability and machineability. In addition to being well suited as a form of safe, resilient flooring, they are employed as a light construction material and sometimes for architectural applications.

As well as being used as a functional, non-slip surface, diamond plate has cosmetic application due to its attractive appearance and is sold as a tiled flooring material. Its black finish makes it the ideal way to contrast and highlight other materials or items, including custom cars in show rooms.

Black aluminum diamond plate is also known as checker plate, tread plate, and Durbar floor plate. Although it is often manufactured from aluminum, steel or stainless steel variants are also made, depending on the specifications required.

Our aluminum diamond plate has been specially formulated and manufactured to create an attractive yet robust material suitable for a wide variety of applications. The raised diamond pattern on the sheets is formed by hot-rolling the aluminum. Embossed (recessed) diamond sheets are also available.

The sheets are made from Aluminum 3003, which consists of aluminum alloyed with 1.2 percent manganese and traces of several other materials. This provides superior strength over pure aluminum, creating a more durable product that can still be cut and shaped effectively. The metal is strain-hardened and partially annealed (a form of treatment the improves malleability). The sheets gain their strength from cold-working alone and cannot be heat treated.

The result is that aluminum diamond plate sheets have good innate corrosion resistance and moderate strength for their thickness. As well as being robust and lightweight, Aluminum 3003 is moisture and weather-resistant. The raised diamond pattern provides a high degree of slip resistance despite the smooth, mirror finish which gives the product a reflective surface and unique decorative appearance. The powder coating on the sheet itself offers another durable layer of protection.

Aluminum 3003 has a wide range of applications in chemical equipment and sheet metal work, as well as cooking utensils and pressure vessels, garage doors, awning slats, storage and gasoline tanks and a variety of drawn and spun components. In sheet form, a relatively low thickness nevertheless provides a high degree of rigidity, whilst remaining formable under the right circumstances.

Aluminum 3003’s excellent machinability for its strength means it can easily be cut, shaped and finished while remaining a durable and versatile material. It is straightforward to weld, drill, saw, shear and form, with little wear on tools. Diamond sheets can be cut down to the required size and shape with minimal effort, whilst the pre-formed diamond texture provides an attractive and anti-slip surface to the aluminum. This makes it popular as a flooring material, particularly where safety is an issue or where surfaces need to be resistant to dirt and moisture and easy to clean.


0.063-inch diamond plate is suitable for the majority of applications. Its diamond texture gives excellent anti-skid properties, and it is often used in industrial settings for stairways, catwalks, ramps and walkways where wet conditions may otherwise pose a risk of sliding or falling. These non-slip properties also make it a common solution for ambulance floors and for the footplates of firetrucks, as well as domestic truck beds and trailer floors.

Diamond plate can also be used for wall panels, counter tops and tiling for other surfaces, and various architectural uses. Since it is easy to machine as well as being robust and attractive, diamond plate tool boxes are another popular application. It is frequently employed to finish edges and corners of items made of other materials, where an extra element of wear-resistance is required. When fitting diamond plate in sheets or angles, care should be taken to select the right materials for fixing. Zinc-plated screws can be used but aluminum rivets or other fixings may contribute to corrosion due to the differing electrolytic properties of the metals. If in doubt seek advice and be sure to match materials appropriately to avoid long-term problems.

Overall, the corrosion-resistant properties and weather-proof nature of the aluminum alloy and powder coating used, means that maintaining the appearance of the product should be a simple matter. Maintenance is usually a case of brushing and wiping clean, though in many instances this will not be necessary at all.

    The semi-gloss black is great and the powder coating makes it so durable. I think I want to do white for my next project and will come here for that

    Badass material! Used it for my truck bed and it looks awesome. I got the 0.045 and it was thin enough to cut with tin snips, but thick enough to be durable in my truck. Look to install this on my 5th wheeler later this year. Coming here for sure.
