1100 H14 Aluminium Circle Aluminum Disk For Road Sign Product

Aluminium discs, also known as aluminium circles, are manufactured by punching or cutting them from an aluminium coil, and are widely used in road and traffic signs. They are gaining popularity due to their lower density compared to stainless steel and superior strength to plastic. Most of these discs are exported to the Middle East and Europe, with a monthly shipment exceeding 200 tons owing to their good and stable quality offered at a competitive price.

Why Aluminum Circle Is Used for Road Signs

Lightweight and Easy to Install

Aluminum circle disks are lightweight, making road signs easier to transport, install, replace, and maintain compared with heavier metal materials.

Good Processing Performance

Aluminum round sheets can be processed by stamping, spinning, stretching, cutting, and forming. This allows manufacturers to produce different road sign shapes, sizes, and structures efficiently.

Corrosion Resistance and Durability

Aluminum circles have good corrosion resistance and long service life, especially when prepainted, anodized, or surface treated. This makes them suitable for outdoor traffic sign applications exposed to rain, sunlight, and changing weather.

Stable Surface for Coating and Printing

The flat and clean surface of aluminum disk material is suitable for color coating, reflective film lamination, printing, and sign graphics, helping road signs maintain clear visibility and consistent appearance.

Recyclable and Environmentally Friendly

Aluminum is recyclable and supports sustainable sign production. Recyclability helps reduce material waste and environmental impact throughout the product lifecycle.

FAQ About Prepainted Aluminum Circle and Aluminum Disk

What sizes of aluminum circle can you produce?

Conventional aluminum discs are available in diameters such as 300mm, 400mm, 500mm, 600mm, and 800mm. Customized aluminum circles can be supplied within a diameter range of 100-800mm according to customer requirements.

Can you supply sample pieces before bulk order?

Yes. Small sample pieces can be supplied for checking quality, color, coating, and processing performance before bulk order.

What color options are available for prepainted aluminum disks?

Color coated aluminum disks can be produced according to customer requirements, actual samples, or specified project color standards.

What thickness range of aluminum disks can you produce?

For punched aluminum disks, the available thickness range is usually not larger than 1.20mm. Specific thickness should be confirmed according to alloy, temper, diameter, and application requirements.
