Tarpaulin, generally known as tarp, is a large sheet of strong, flexible, water-resistant or waterproof material, made of plastics such as polyethylene or Polypropylene. Inexpensive modern tarpaulins are made from woven fabric of High Density Polyethylene and then coated with Low Density Polyethylene on single or both side to make it water-resistance or waterproof. Tarpaulins often have reinforced grommets (usually Aluminum eyelets) at the corners and along the sides to form attachment points for rope, allowing them to be tied down or suspended. When treated against ultraviolet light, these tarpaulins can last for years exposed to the elements. Tarpaulins multiple use includes providing shelter from the natural elements, i.e. wind, rain, or sunlight or as a ground sheet or a fly in camping, a drop sheet for painting, for protecting the infield of a sports arena, and for protecting rail wagons carrying materials or wood piles. Polyethylene tarpaulins have proven to be a popular source to procure an inexpensive, water resistant fabric.
Benefits of Tarpaulin
Water and UV-resistant, good weather ability.

Designed for extreme outdoor use.
Good flexibility, easy handling, excellent tensile strength and tear strength.
Economical, easy to transport and sustain long time for good performance.
Excellent choice for the truck tarp industry.
Resistant to mildew and chemicals
Excellent resistibility to Agro-chemicals like phosphorus, ammonia, sulfur
Types : Depending upon the manufacturing criteria both during weaving and coating, tarpaulins can be made in different weight categories as per square meters. Generally, it is made from100 GSM to 400 GSM. GSM is a unit to specify weight in grams of finished fabric or tarpaulin per square meters.
Size Waterproof tarps typically come in ready-made sizes or rolls. Ready-made tarps vary but are usually available in sizes from 6 feet (2 meters) to 90 feet (30 meters). Polytarps are measured by two different sizes--the cut size and the finished size. Shrinkage occurs during the manufacturing and the finished size may be up to 6 inches smaller than the cut size. Roll sizes of waterproof tarps also vary and can generally be customized for the buyer. However, 200 meters is a standard length.
