SimTek EcoStone and Ashland Fencing

SimTek Ecostone is now Bufftech® Allegheny™ – same great product now offered under a different name.

EcoStone is available in a Residential-Grade Fencing System or a Commercial-Grade Fencing System (EcoStone Plus).

SimRock Fence is a SimTek Fence factory-direct dealer and installer and that we work directly with the SimTek Fence factory so our customers get the best pricing on the fencing system and the best, factory-approved installation. We do not hire anyone else to install the fence. All SimRock Fence installations are completed by SimRock Fence employees and we stand behind our installations. We will install the EcoStone Fencing System anywhere in the state of Utah and will ship the product anywhere in the continental United States and Canada.
