Aluminum circle plate for traffic signs are usually made of 3003 aluminum alloy, which is an aluminum-based alloy with elements such as manganese and magnesium. 3003 aluminum alloy has good corrosion resistance, strength and plasticity, which can meet the requirements for the production and installation of traffic signs. The thickness and size of aluminum circle for traffic signs depend on the specific application scenarios and specifications. Generally speaking, the thickness of aluminum discs for traffic signs ranges from 0.5mm to 3mm, while the size depends on the size of the sign and the installation location.

For the quality and performance requirements of aluminum circle plate for traffic signs, the following are some aspects to be noted:


High purity 3003 aluminum alloy is required to ensure that the aluminum discs are uniform and free of impurities and slag.


According to the size and installation location of the traffic sign, it is necessary to choose different thicknesses of aluminum circle plate. Generally speaking, the thickness ranges from 0.5mm to 3mm.

Surface treatment:

The aluminum circle for traffic signs need to be anodized to improve their corrosion resistance and aesthetics. At the same time, it also needs to be painted to enhance the color and durability of the sign.


The aluminum circles are required to be processed with high precision without obvious deformation and warping. In addition, it is also necessary to test the flatness and curvature of the aluminum disc to ensure that it meets the requirements of the relevant standards and specifications.


The aluminum discs of traffic signs need to be easy to install and can be firmly fixed on the road surface. Therefore, the edges of the aluminum discs need to be bent or rolled in the production process to improve their installation stability and durability.

In conclusion, in order to ensure the safety and durability of the traffic signs, it is necessary to choose the aluminum circle plate for traffic signs material with stable quality and excellent performance, and carry out strict processing and treatment.
