Economy Grey recycled rolled rubber flooring is an inexpensive alternative to our standard rolled rubber products. Economy Gery rubber is a durable rolled rubber but slightly less dense than our standard tough rolls. Economy rubber rolls are made from industrial recycled rubber that is naturally made during the production of our standard recycled rubber products and combined with recycled white wall car tires. Every effort is made to eliminate aluminum but is not uncommon to find the occasional piece in this product. These economy rolls have an anti slip and slightly softer surface to help keep traction even in the most demanding movements. Economy rolls work well as home gym flooring or in commercial gyms where heavy exercise equipment is being used and the customer is in need of the inexpensive commercial grade rubber flooring solution. If used as a commercial flooring, we recommend a 3/8″ or thicker.
