Round aluminum discs for road signs are aluminum materials specially designed for the manufacture of traffic signs, signboards and other road signs. They are ideal materials for the manufacture of traffic signs because of their light weight, durability, corrosion resistance and good processability. With proper surface treatment and design, these aluminum discs can improve road safety and ensure the visibility of traffic signs.
Specification of round aluminum discs for road signs:
- Alloy: Generally, aluminum alloys such as 1060, 3003, and 5052 are selected. Among them, 3003 aluminum alloy is widely used in the field of traffic signs and has good corrosion resistance and strength.
- Thickness: The thickness is usually between 1.0mm-3.0mm, and can be selected according to factors such as the size of the sign, the use environment, and wind resistance requirements. Generally speaking, larger signs or signs used in windy areas will use thicker aluminum discs to enhance the strength and wind resistance of the signs.
- Diameter: Common diameters of round aluminum discs are 600mm, 800mm, 1000mm, etc. Different application scenarios and sign types will use aluminum discs of different diameters. For example, on highways, due to the high speed of vehicles, larger signs are needed to ensure visibility, and aluminum discs with a diameter of 800mm or 1000mm may be selected; while on urban roads, aluminum discs with a diameter of 600mm can generally meet the needs.
- Cutting: According to the diameter size required by the design, use cutting equipment to cut the aluminum plate into round aluminum discs. Common cutting methods include laser cutting, plasma cutting, mechanical cutting, etc. to ensure the dimensional accuracy and edge quality of the discs.
- Surface treatment: In order to improve the corrosion resistance, wear resistance and reflective performance of the aluminum discs, it is necessary to perform surface treatment on them. Common treatment methods include anodizing, painting, film pasting, etc. Among them, film pasting is to paste the reflective film on the surface of the aluminum disc, which is one of the key processes for making round aluminum discs for road signs.
Features of aluminum discs for road signs:
- Lightweight: The density of aluminum is relatively low, which makes the round aluminum discs light, easy to transport, install and maintain, and reduces labor intensity and cost.
- Corrosion resistance: Aluminum easily reacts with oxygen in the air, forming a dense aluminum oxide film on the surface, which can effectively prevent further corrosion and can be used in outdoor environments for a long time, extending the service life of road signs.
- Easy to process: It has good plasticity and ductility. It can be made into circular aluminum discs of different diameters, thicknesses and shapes through various processing methods such as stamping, cutting, and bending to meet the design requirements of various road signs.
- Good reflectivity: The surface is smooth and can reflect light well. After matching with reflective film, it can improve the visibility of road signs at night or in low visibility conditions, and enhance the warning and indication effect.
- Strong stability: The chemical properties of aluminum discs are relatively stable, and they are not easily affected by external environmental factors such as temperature and humidity changes. They can maintain good shape and performance, ensuring the accuracy and reliability of road signs.
Application scenarios of round aluminum road signs:
- Indicator signs: Used to indicate road direction, location, distance and other information, such as straight signs, left turn signs, right turn signs, etc., to help drivers accurately choose the driving route.
- Warning signs: used to warn vehicles and pedestrians of dangerous places, such as sharp turn signs, steep slope signs, narrow road signs, etc., to remind drivers to take corresponding safety measures in advance.
- Prohibition signs: used to prohibit or restrict certain traffic behaviors of vehicles and pedestrians, such as no-passing signs, no-parking signs, speed limit signs, etc., to regulate traffic order and ensure traffic safety.
