When a small, conventional tarp just will not do, visit Tarp Surplus for its selection of heavy duty vinyl tarp covers in either 13- or 18-ounce varieties. These super-strong vinyl tarp covers have a high resistance to abrasion and are extremely difficult to tear. For construction or industrial purposes, or any type of heavy cargo-hauling you may be doing, these heat-sealed, waterproof tarps will do a great job of warding off oil, grease, mildew and acid.
When vinyl fabric is laminated, a polyester reinforced scrim layer is pressed between at least two layers (sometimes more) of PVC film. Then, the layers get compressed via pressure, heat and an adhesive, helping to form one integrated piece. What you end up with is a fabric notable for its exceptional durability, enhancing its use for outdoor structures.
An even stronger option than laminated vinyl fabric is coated-PVC vinyl fabric. When fabric is treated in this fashion, it is extremely resistant to abrasion and tearing. The coated vinyl material is comprised of a fabric scrim that supports the hot molten coating, which is where the high tensile strength comes from. When the tarp is coated in this way, it will not run the risk of de-lamination that is present if the tarp fabric is merely laminated rather than coated. The laminated fabric is available in either 13 oz. or 18 oz. per square yard. The coated fabric is available only in 18 oz. per square yard.
