We generally cast aluminum spike, plastic spike, spike ceramics, glass ball spike spike into the general category. Below classified by function in detail about the spike. Ceramic spike made of cement ceramics, round, early application is more, during transport frangible spike classification is generally not recommended. Spike made of glass glass ball, the early application are more difficult construction and installation, less basic applications. It is generally not recommended. FAQ sheeting poor impact resistance spike protruding signs the most important issue currently on the market is the reflector impact of intolerance, more than 80% of the products have this kind of problem spike, on the due process problems, most reflector ultrasonically welded to the housing spike specifications, reflective film by the impact on the loss and fracture, when it rains the rain immersion, lose reflective brightness. Inspection Methods: spike reflector impact test, after the white extraction, 1KG spike the ball free fall, vertical impact spike reflector surface, and then into the water, and then measuring the brightness of the reflector. Reflector without water, reflective brightness is not reduced.
