Since 1998, Cryzal manufactures and distributes high-end tempered glass road marking products. These became worldwide successes over the years, and set new standards of horizontal marking. Our product&＃39;s constancy and high reputation among our customers greatly participated in making us a preferred manufacturer for tempered glass road marking products. As a result, we produce and distribute more than 500 000 studs per annum. Through continuous work based on the useful feedbacks of our national and international distributors, our products are today approved by several ministries and transport authorities. The Holophane markers are actually often used as a reference when national authorities want to update their performance requirements for retroreflecting road studs. This is the rewarding outcome of more than 10 years of technical support and collaboration with our customers and with several road & transport authorities in countries like France, the UK, the USA, Holland, Germany, Italy, Turkey and others.
