1100 Aluminum Diamond Plate Description
When sourcing non-slip, corrosion-resistant metal for light-duty, decorative, or highly corrosive environments, the 1100 aluminum diamond plate is an industry standard.
As a China aluminum supplier, GNEE manufactures and exports premium 1100 aluminum tread plates globally, designed to meet strict dimensional tolerances and aesthetic requirements.

The Engineering Reality of 1100 Aluminum
Because 1100 is commercially pure, it is soft. It has a relatively low tensile strength compared to 3003 or 5052 alloys. You should not use 1100 aluminum diamond plate for structural, heavy-load-bearing applications (such as flatbed tow trucks, industrial catwalks spanning large gaps, or forklift ramps).
However, this "softness" is exactly what makes 1100 the ultimate choice for specific fabrications. It is highly ductile, meaning it can be subjected to severe forming, bending, and spinning without cracking. If you are building enclosed trailers, food trucks, walk-in coolers, or architectural wainscoting where the metal is supported by a subfloor or wall, 1100 is highly cost-effective, easy to fabricate, and aesthetically superior.
Tempers of 1100 Aluminum Diamond Plate
The temper of the aluminum determines its hardness, yield strength, and how tightly you can bend it before it fractures. We supply 1100 aluminum diamond plates in several tempers to match your fabrication line:
- 1100-O Aluminum Diamond Plate: This is the softest state available. The metal has been heated to remove internal stresses. It is ideal for deep drawing or extreme forming. If you need to wrap a diamond plate tightly around a curved pillar or a sharp 90-degree corner without any radius cracking, the "O" temper is your best choice.
- 1100-H14 Aluminum Diamond Plate: This is the most popular temper we sell for diamond plates. The metal is strain-hardened to achieve a balance between strength and formability. You can still easily break-form it to 90 degrees for stair nosing or trailer edges, but it holds its flat shape much better than the "O" temper during installation.
- 1100-H24 Aluminum Diamond Plate: Very similar in strength to H14, but it has slightly better elongation properties. It is often preferred when complex bending is required but the final product still needs moderate rigidity.
- 1100-H114 Aluminum Diamond Plate: This is a temper designation specific to embossed or patterned sheets. It indicates that the material was patterned from an "O" temper sheet, but the actual mechanical pressing of the diamond pattern imparted work-hardening to the metal, raising its final strength closer to an H14 level.
Surface Finishes for 1100 Aluminum Diamond Plate
The aesthetic and functional requirement of your project will dictate the surface finish. GNEE offers two primary finishes:
Mill Finish (Standard): This is the natural appearance of the aluminum as it exits the rolling mill. It has a matte, slightly dull, silver-gray look. It is cost-effective and perfectly suited for hidden applications, industrial freezer floors, or interior utility trailer linings where a mirror-like shine is not required.
Bright Finish (High Polish/Mirror-like): The 1100 alloy polishes better than almost any other aluminum grade. Our bright finish 1100 aluminum diamond plate has a highly reflective, chrome-like appearance. This is heavily utilized in fire trucks, customized RVs, food truck interiors, and commercial gym walls. Aside from aesthetics, a bright finish is significantly easier to wipe down and sanitize, making it ideal for food-grade environments.
Pattern Classifications of 1100 Aluminum Tread Plate
The raised pattern on the plate is not just for decoration; it dictates traction multidirectionality and ease of cleaning. GNEE manufactures several distinct patterns:
- Classic 1-Bar (Diamond / Compass Pattern): Features a single, raised, diamond-shaped lug. It offers aggressive traction but can be slightly harder to sweep clean due to the isolated raised bumps.
- 3-Bar Pattern: Features clusters of three parallel bars set at opposing angles. It provides excellent slip resistance and a rugged, industrial aesthetic.
- 5-Bar Pattern (Small & Big): This is the global standard for aluminum checker plates.
Small 5-Bar: The length of the raised bar is approximately 34mm. It looks visually denser and is excellent for small panels, toolboxes, and decorative trim.
Big 5-Bar: The bar length is 42mm. The wider spacing makes this pattern the best choice for flooring, as it is much easier to sweep dirt and hose water off the surface without debris getting stuck between the lugs.
- Stucco Embossed: While not a traditional "diamond" plate, we also roll 1100 aluminum with a stucco (pebble) texture, widely used for refrigeration lining to hide dents and scratches.

Common Applications Of 1100 Aluminum Tread Plate
- Food Truck and Concession Trailer Floors: Health codes require surfaces that will not rust and can be sanitized daily. The bright finish 1100 plate is perfect for these subfloor-supported applications.
- Architectural Wainscoting & Wall Protection: Used in commercial garages, retail stores, and home gyms. The 1100-H14 0.8mm or 1.5mm sheets are lightweight, easy to glue or rivet to drywall, and provide excellent scuff protection.
- Walk-in Refrigeration & Freezers: The 1100 alloy does not become brittle at sub-zero temperatures. It is widely used as the interior floor lining and exterior kick-plates for commercial coolers.
- RV Camper Rock Guards & Trim: Fabricators love the 1100 alloy because they can easily bend the diamond plate around the curved front profiles of caravans to protect against road gravel, without the raised diamonds cracking.
- Custom Toolboxes: Lightweight, weather-proof, and visually striking, bright finish 1100 sheets are commonly bent into siding for truck-bed toolboxes.
The GNEE Manufacturing Advantage
Since 2008, GNEE has been a trusted cornerstone in the global steel and aluminum supply chain. Operating with 8 subsidiaries across regions like Tianjin, Hong Kong, and Singapore, we understand that supplying metal means delivering it free of defects, on time, and ready for your machines.
Why Global Buyers Trust GNEE:
- Ultrasonic Thickness Control: We don't sell "short thickness." If you order 2.0mm, our advanced rolling mills ensure the base thickness is exactly 2.0mm, independent of the 1.5mm raised bar height.
- Immaculate Surface Protection: Aluminum is prone to water stains (white rust) if exposed to marine humidity during shipping. We mitigate this entirely.
- Export-Grade Packaging: We interleave waterproof kraft paper or PVC protective film between every single sheet. The entire bundle is then wrapped in heavy-duty polyethylene, packed with industrial desiccants, and secured with steel strapping onto fumigated wooden pallets. It arrives at your port in pristine condition.
Q&A
Q1: Can I weld 1100 aluminum diamond plate?
A: Yes, 1100 aluminum is highly weldable using TIG or MIG processes. For the best results and color match, use an ER1100 filler rod. If you need slightly higher strength in the weld joint, ER4043 can also be used. However, remember that the heat-affected zone will lose its work-hardened strength and revert to an "O" temper (fully soft) state.
Q2: Is 1100 aluminum diamond plate suitable for outdoor marine environments?
A: 1100 aluminum has outstanding general corrosion resistance and handles rain and fresh water perfectly. However, for direct saltwater or marine environments (like boat decks or docks), we strongly recommend upgrading to a 5052 aluminum diamond plate, which contains magnesium and is specifically engineered to resist salt spray corrosion.
Q3: How do I cut the 1100 aluminum checker plate?
A: Because it is a softer alloy, 1100 is very easy to cut. Thin sheets (0.8mm - 1.5mm) can be sheared or cut with a high-quality jigsaw using an aluminum-cutting blade. For thicker plates (up to 10mm), plasma cutting, laser cutting, or heavy industrial shears are recommended. Use a lubricant to prevent the soft aluminum from gumming up your blades.
Q4: How do I maintain the shine on a bright finish 1100 diamond plate?
A: It is very easy to maintain. Simply wash it with warm water and a mild, non-abrasive detergent. Avoid strong alkaline cleaners or stiff wire brushes, as the commercially pure 1100 aluminum is relatively soft and can be scratched. For restoration, standard aluminum polishes work exceptionally well to bring back the mirror-like finish.
