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.
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 are 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.
