In this article, one of the leading US tarp suppliers provides interesting and helpful info to those looking for buy a poly tarp online. While most of us think of the economy blue tarps found in most hardware stores, there are actually more variety than that.
Although polyethylene material is the standard, common poly tarps can be found in a different colors, and strength variations.
In
addition to the ever-present silver and blue tarps, there are green, yellow, white,
and even camouflage tarps.
-------------------
The modern poly tarpaulin that is sold in the United States are all imported from the far East mainly from China, although Vietnam and India are now large producers of poly tarps. The majority of the polyethylene waterproof material is manufactured in South Korea, and is then exported to the countries mentioned above and fabricated into fully waterproof poly tarps.
A large amount of the workers that produce poly tarps are aged from 16 to 30, work long hours in medium size factories. Although tarp manufacturing is mechanized, a lot of the work is done by the factory operatives. For example, the hems and grommets are usually made by hand. Most of the factories are situated in Qingdao Northern China. The tarps are stuffed into 40ft containers transported to the port where they are shipped all over the world.
Blue poly tarps in the main are all made with three layers of polyethylene material. The main body of the tarp is made from strips of high density woven polyethylene which is woven into a sheet. This is done in a special weaving machine and then coated on both sides with low density polyethylene to around 30 microns. The coating is then colored, this can be any color requested however the most common in the USA is blue. The three main weights that are sold in the USA are as follows; 3.0 oz per sq yard 10 x10 weave, 4.5oz 12x12 weave and 6oz 14x14 weave. Typically grommets are at one yard intervals on the 3.0oz, and grommets at every eighteen inches with the 4.5oz and 6.0oz product.

Note: Poly tarps are strengthened by nylon strands that are coated, then bonded
on both sides with the polyethylene layers. The 10x10 or 12x12 refer to the number
of mesh strands per foot of tarpaulin fabric. The greater the mesh density, and
the heavier the nylon strands (measured in denier), the greater the durability
and flexibility.
--------------------
All good quality tarpaulins should have a least a 3% U.V. inhibitor added. This additive extends the life of the tarp during long periods of direct sunshine. As previously mentioned tarpaulins are available in a variety of weights. Generally the heavier the tarp the better the quality, the ounce per square yard and the mil thickness are two ways of gauging the quality of a tarp. Thinner tarps are usually found in flea markets and some online retail sites.
Tarps can be purchased in many locations, hardware stores, auction sites, flee markets, & online vendors. The benefit of purchasing online is that you have a far greater choice of quality, size, color and the convenience of having it dropped to your door. Most internet sellers offer tarps in a very wide range of colors, even red and yellow are on offer. Camouflage tarps and fire retardent poly tarps are also very popular and once again can be purchased from many providers.
The poly tarp can be used in many ways for home improvement; roof repair, waterproofing the side of buildings during construction, covering building materials on site, as damp proof membrane, removing grass/leaves from the back yard, covering logs, use as a drop cloth, covering garden tractor, boat cover, and many other uses. For roofing repairs the best option is a 6oz silver tarp, as this will stand up to the sun rays to the greatest extent. For covering the side of a building, the 6.0z tarp is again the ideal choice. It is the most popular heavy duty tarp. For all other uses the 4.5oz or 3.0z would be good for the job.
