Improving the static compressive strength of Road Studs is mainly achieved by increasing the strength of Road Studs material. At present, the Road Studs sold in the domestic market are divided into metal material Road Studs (such as aluminum Road Studs), engineering plastic material Road Studs (such as engineering plastic Road Studs made of polycarbonate, polyacrylic acid, etc.) and mixed materials. Road Studs (such as Road Studs with engineering plastic shell + quartz sand filling). Among them, Road Studs made of metal have the highest compressive strength, followed by Road Studs made of engineering plastics and mixed materials.
