The RhinoRock Concrete Fence is affordable because we only use our proprietary, high performance (5,800psi) concrete only where it is needed. The inside portion of a typical concrete fence panel doesn't contribute to the surface texture or to its weather resistance... so, through a revolutionary new process, we eliminated it along with thousands of pounds of concrete that now you don't have to pay for! The RhinoRock Concrete Fence utilizes a patented column and panel attachment system that has been used in the traditional concrete fencing industry for the past 14 years. Two patents and two pending patents make the RhinoRock system extremely efficient and cost effective to produce and install.
