Below is a list of Tarps manufacturers from Madison, Wisconsin. Tarps are large protective covers used to protect objects from unwanted exposure to moisture, dirt, dust or other hazards. The word “tarp” is short for “tarpaulin.” Tarpaulin is believed to be derivative of the words “pall” and “tar,” the combination of which would indicate a covering coated with tar. Modern tarps certainly fit this description, at least to a point; they are used as coverings and are known for their water resistance.
