This ball are usually made of ductile iron materials through a casting process. This type of road sign usually has a hemispherical shape and can be used to mark road edges. The characteristics of ductile iron material make this kind of road signs resistant to corrosion and wear, and can usually be used in outdoor environments for a long time without losing their appearance and functionality. They are often painted in bright colors for increased visibility and warning. These road signs can also be made reflective on the surface as needed to improve visibility and traffic safety at night. Generally, ductile iron cast hemispheric road signs have high durability and stability and are suitable for marking and guiding public roads and traffic flow lines.
