Our aluminium circles are specially manufactured for road traffic signs, warning signs, guide signs and other outdoor traffic facilities, using premium pure aluminium and alloy materials to meet strict international traffic safety standards.
Mainly made of 1050, 1060, 3003 and 5052 grade aluminium, these round blanks feature outstanding corrosion resistance, weather resistance and flatness. They are lightweight, high-strength, non-rusting and have a long service life, perfectly adapting to long-term outdoor exposure, rain, snow and extreme temperature changes.
With a smooth, burr-free surface, our aluminium circles are highly compatible with reflective film lamination, screen printing and digital printing, ensuring clear and long-lasting sign display and excellent daytime and nighttime visibility. They are easy to punch, cut and form, supporting efficient mass production of standard and custom road signs for highways, urban roads, rural roads and industrial traffic areas.
Aluminium sheets for road signs are also called traffic sign aluminium sheets, road sign blanks, reflective sign aluminium plates, highway sign aluminium sheets, and traffic sign substrates.
Common shapes include square, rectangular, round, triangular, octagonal and custom-cut special shapes for different traffic instructions. They usually adopt a composite structure: an aluminium alloy base sheet (mostly 1100, 3003, 3104, 5052) bonded with reflective film for high visibility at night.
These sheets are widely used in highway signs, city road signs, warning signs, traffic guidance boards, and safety signs.
Major Purchasing Countries:
The United States, Canada, Australia, Germany, the UK, France, UAE, Saudi Arabia, Malaysia, Thailand, Indonesia and South Africa. Strong demand comes from infrastructure construction, transportation projects and urban traffic management.
To ensure quality of Aluminium Circles for Road Signs: We use 1050/1060/1100/3003 alloy, strict thickness & diameter tolerance, smooth surface without scratches, uniform mechanical properties, corrosion resistance, and compliance with traffic material standards. Stable stamping performance ensures long service life.
We mainly use high-quality alloys including 1050, 1060, 1100, 3003, and 5052. These grades offer excellent durability, strength, and resistance to environmental stress.
Yes. The smooth, burr-free surface of our aluminium sheets makes them perfectly compatible with reflective film lamination, screen printing, and digital printing, ensuring outstanding visibility both day and night.
We supply standard round, square, rectangular, triangular, and octagonal shapes. Custom shapes can also be precision-cut based on specific client designs and road safety standards.
Our aluminium circles are highly corrosion-resistant and non-rusting. They feature outstanding weather resistance, keeping their shape and properties intact under extreme heat, snow, heavy rain, and intense UV exposure.
Yes. We implement strict thickness and diameter tolerances during manufacturing. This ensures scratch-free surfaces, uniform mechanical performance, and stable stamping for a long operational lifespan.
