Simtek makes beautiful maintenance free fences made out of plastic. When you think of a plastic fence your probably thinking it would probably look ugly or not be very durable, but that is not the case with these Simtek fences. They look exactly like beautiful large granite stone or concrete walls. These fences are tougher than vinyl too. You can see the video of a star baseball pitcher throwing 90 mph fastballs at it and it doesn’t phase the fence. If someone does graffiti on your fence, unlike other fences you have to repaint, you can simply use a citrus based cleaner to get off the graffiti on Simtek fences.
