The Application of Aluminium in Traffic Signs
10-30
Aluminium is a staple in the manufacturing of traffic signs worldwide due to its lightweight properties, durability, and resistance to weathering. From Aluminium Composite Panels to Premium External Aluminium Composite Mirrors, the adaptability of aluminium materials has made them the go-to choice for road signage, enhancing visibility, safety, and longevity on the road.
What is Aluminium Signs?
Aluminium signs refer to signage panels made from pure aluminium or aluminium composite materials (ACM). These signs are primarily used for road signs, directional signage, and regulatory signs. The natural properties of aluminium, such as its resistance to rust, make it ideal for outdoor use. To further enhance their performance, aluminium signs often incorporate reflective coatings, increasing visibility both day and night.
What Aluminium is Used for Road Signs?
For road signs, aluminium composite materials (ACM) are highly popular, consisting of layers of aluminium with a lightweight polyethylene core in between. The most commonly used aluminium alloys for road signs include 1050, 1060, and 1100 in the 1xxx series, known for their excellent corrosion resistance and cost-efficiency. In high-durability applications, aluminium sandwich panels and premium external aluminium composite mirrors may be used to add a reflective, mirror-like surface that withstands harsh weather conditions.
How Long Do Aluminium Signs Last?
Aluminium signs are well-regarded for their longevity, with a typical lifespan of 7 to 10 years, and in some cases, even longer depending on environmental exposure. High-quality aluminium composite panels (ACP) and aluminium composite materials (ACM) significantly enhance durability. Alum panels treated with UV-resistant coatings are particularly effective in extending lifespan, as they resist fading and weather-related wear, ensuring that signs maintain clarity and legibility over time.
What is the Difference between Aluminium and Aluminium Composite Signs?
Pure aluminium signs are made entirely from aluminium and are valued for their high durability and recyclability. In contrast, aluminium composite signs (or aluminium composite panels) are made by layering aluminium sheets around a core, often made of polyethylene. This structure provides exceptional strength while keeping the sign lightweight. Additionally, aluminium composite signs offer greater flexibility in terms of finishes, like premium external aluminium composite mirror surfaces, and can incorporate textures or reflective qualities that standard aluminium signs do not. This makes them more versatile and economical for larger or customized signage applications.
In summary, aluminium and aluminium composite materials are essential for traffic signage due to their durability, weather resistance, and adaptability in design. Aluminium wall panels and aluminium sandwich panels add structural integrity to road signs, ensuring clear visibility and extended lifespan, crucial for maintaining safe and navigable roads.
