Sheeting rubber products are most often sold in the form of rolls. Our sheet rubber rolls are usually stocked in gauges between 1/32” to 2” in thickness, depending on the specific type of elastomer. Since our sheet rubber is sold in roll form, they can be acquired in custom lengths of up to 25 or 50 ft according to your specifications. This will help ensure that you have the exact amount of material you need for your project. More importantly, however, you should know which type of material to choose from.
