Characteristics
1. Excellent weathering resistance and long life span
2. Fine wear resistance and chemistry stability. They are able to withstand the erosion of tire, sand, different kinds of solvent and oil fuel. Moreover they also have strong resistance to acid rain as well as salt fog. As a consequence, they can be used in various kinds of severe road conditions for a long time.
3. Safe, reliable and strong warning function.

Technology Index
1. Glass road stud are made from tempered optical glass of highly crystal silicon plating the silver reflective layer and its reverse reflection coefficient is over 80mcd/LX.
2. High compression strength. Its pressure- resistant degree is more than 157KN. It is well proved that they are still in good condition after being largely installed in the experimental road withstanding the pressure of large container loading vehicles for more than one year
3. Its economic effectiveness is so obvious that worth widely using by the masses.
4. This product has already been applied for the patent of People's Republic of China and Geneva.
