By the very nature of the product damage, wear, or discolouration may occur due to a wide range of reasons. AATi pledges to give advice on a sensible course of action to remedy problems with either its own products or those of other manufacturers.
We have patterns which accommodate for our products which were installed from over 25 years ago to the present day, thus having the capability to either restore or upgrade old products. Wear takes place principally on the nose or leading edge when gradual abrasion by passenger footfall removes metal from around the encapsulated silicon carbide granules.
