Introduction to aluminum discs for traffic signs

Aluminum discs for traffic signs are one of the important raw materials for making road traffic signs. These aluminum discs are usually cut from high-purity aluminum plates (such as 1050 aluminum circle, 1100 or 3003 alloys). They have good weather resistance, oxidation resistance and mechanical strength, and are suitable for long-term outdoor use.

In the manufacturing process of traffic signs, aluminum discs can be processed according to the standard sizes stipulated by the country and used to make circular or partially circular traffic signs, such as speed limit signs, no-travel signs and other circular pattern signs. wait. Their diameter and thickness can be customized according to actual needs to meet the requirements of different application scenarios and climate conditions.

Specifications of aluminum discs for traffic signs

The specifications of aluminum discs for traffic signs can be customized according to actual application requirements, but usually, the specifications of aluminum discs include diameter and thickness:

Diameter: The blanking diameter may range from 85 mm to 900 mm, depending on the sign design requirements and national standards.

Thickness: The thickness of the roll material is generally between 0.4 mm and 6.0 mm, which is also selected based on the design load-bearing, structural strength and environmental conditions of the sign.

In addition, aluminum plates, the raw material for aluminum wafers, also have different width and weight specifications:

Roll width (Width): The common range is 500 mm to 1600 mm.

Coil weight (Weight): The weight of each roll can be 8,000 kg or 10,000 kg, etc.

Aluminum disc alloy for traffic signs

Aluminum discs for traffic signs are usually made of aluminum alloy because aluminum alloy has good weather resistance, mechanical properties and processing properties. Commonly used alloy grades include:

  • 1050: This is a high-purity aluminum alloy containing more than 99.5% aluminum. It has excellent corrosion resistance and conductivity, but its strength is relatively low. This material may be used for traffic signs that do not require high strength, such as some lightweight signs or highly decorative components.
  • 1100: Similar to 1050, it is also a high-purity aluminum alloy with an aluminum content of more than 99.0%. It has excellent formability and weldability, and has a low cost. It is suitable for making traffic signs that do not require high strength.
  • 3003: This alloy contains a small amount of manganese. Its strength is higher than that of the 1000 series aluminum alloy, and it has better corrosion resistance. Therefore, it is often used in outdoor traffic signs that require a certain degree of strength and weather resistance.

In addition, for more complex environmental conditions or occasions with higher requirements on mechanical properties, other series of aluminum alloys such as 5000 series (such as 5052) or 6000 series (such as 6061 Aluminum) may be selected. These alloys have excellent corrosion resistance and tensile strength. Better performance in terms of strength and toughness.

In actual applications, the specific choice of alloy will be determined based on factors such as the design requirements of traffic signs, the use environment, and budget.

Why use aluminum discs to make traffic signs?

Corrosion resistance: Aluminum discs have excellent corrosion resistance and can resist wind and rain erosion, allowing them to maintain clear marking information under various climate conditions. This greatly extends the service life of traffic signs and reduces the frequency of frequent replacements, thereby reducing maintenance costs.

Light and strong: Aluminum discs are both light and strong, which means that when making traffic signs, the stability of the sign can be maintained while reducing the overall weight. This not only facilitates installation, but also reduces safety hazards caused by overweight signs.

Easy to process and install: Aluminum discs have good processing performance and can be cut, bent, etc. according to design requirements to produce traffic signs of various shapes and sizes. In addition, the installation of aluminum discs is relatively simple and can be quickly and accurately fixed at the desired location.

Cost-effectiveness: The price of aluminum discs is relatively reasonable. Compared with other expensive materials, it can better meet the needs of large-scale, low-cost production of traffic signs. At the same time, the recycling value of aluminum wafers is high, which is conducive to environmental protection and sustainable development.

Good reflective properties: The surface of the aluminum disc is smooth and has good reflective properties. Especially at night or under low light conditions, it can improve the recognition of signs by drivers and pedestrians and reduce the risk of traffic accidents.

Aesthetics: The surface of the aluminum disc is smooth and not easy to rust. It maintains a bright and new appearance for a long time, improving the aesthetics of traffic signs.
