Advantage® Cast Iron Tactile Walking Surface Indicator (TWSI) plates are manufactured in strict accordance with ASTM A-48, Class 35B Grey Cast Iron. The Advantage® Cast in Place System is lightweight with exceptional high strength, and utilizes the most advanced metallurgical Engineering Science and Technology to meet and exceed the most stringent municipal standards. Advantage® Cast Iron is aesthetically pleasing, has exceptional longevity and incorporates integral texture for a permanent slip resistant surface.
There are two different methods to install the Advantage® Cast Iron Plates in your curve sidewalk. One is to use the standard tile or tile curve plates and the other is to use the additional wedge system found in the Premier line. When it comes time to replace the cast iron plates, the Premier System makes it easier and faster to extract from concrete.
