We are convinced that the 360 degree Tempered Glass Road Stud which comply with CNS13762 are the best choice.
1.Environmental friendliness: Glass is an environmental friendly and recyclable material. The major element (70%) is SiO2. It's one of the most common element in earth. Concerning the trend of energy conservation and carbon reduction, glass is a better material choice compared with the difficult decomposable plastic materials (in order to prevent the deterioration by UV, the manufacturer has to blend anti-ultraviolet agents in the plastic which is not easy to be decomposed naturally.)
2.Lifespan: Regarding to the actual installations on Taiwan freeways it has been proven that the lifespan of 360 degree Tempered Glass Road Studs is over twenty times greater than the lifespan of plastic road studs.
3. Effective-cost: 「Short-lived goods must be cheap」, that is common sense. We also have to compare the installation cost (road marker, adhesive, installation, traffic management) and social cost (waste of time and gasoline due to traffic jam, work risk and risk of car collisions during road stud replacement).Detailed consideration over 5 years requires with plastic road markers a huge annual budget in order to replace many times the “cheap”plastic markers with short lifetime.
