Aluminum Diamond Plate

Our aluminum diamond plate sheets are pressed aluminum sheets bearing a raised diamond pattern on one side. Diamond plate is also called tread plates, checker plates, and/or durbar plates. Here at SizeMetal, our sheets are top quality and even our modern-looking raised diamond pattern gives you a striking look. A great benefit of aluminum diamond plate is that it is weather and corrosion-proof, easy to clean, and skid-resistant. This makes them suitable for a wide variety of applications for both indoors and outdoors. 

This material is typically used for both industrial and domestic purposes due to its high strength, low cost, malleability, and machinability. It is commonly used as a form of safe, resilient flooring and can also be used as a light construction material.

On top of being durable and non-slip, many use aluminum diamond plate for cosmetic applications due to its attractive appearance and shiny finish. Many companies use it for flooring or wainscoting to add some contrast or even highlight parts of the space. One of our personal favorite applications for aluminum diamond plate is using it as wainscoting in car showrooms.

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, tiling for other surfaces, and various architectural uses. Since it is easy to machine along with 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.

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 is formed by hot-rolling the aluminum. Diamond plates can be polished to a highly reflective finish for applications that require a beautiful surface as well as a tough exterior.

Our 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.

Aluminum 3003 has a wide range of applications in chemical equipment, sheet metal work, cooking utensils, 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 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. 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.

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