Several important factors that determine the strength of durable tarpaulin are as follows.
#1-Weight
When looking at the tarps, you will see that some are listed as 3 or 7-ounce tarps, while others are 16 or 18-ounce tarps. What does that weight mean? It is the weight per square yard. If you surround that tarp into a yard, it will weigh several ounces. Higher weights may be stronger, but this is not always the best way to judge.
#2-Thickness
In addition to the weight, the thickness of the tarp is a certain mil. For example, the thickness of a common blue tarp is 4 mils. A mil is equal to one-thousandth of an inch. From an angle, the thickness of 4 mils is about the same as the thickness of a piece of computer paper. The blue polyethylene tarp is about the same thickness as a piece of paper, but the tarp is stronger because it is made of polyester braided thread. This does not mean that it is strong enough to hold several pounds of ice and snow without tearing.
What about the other end, the transparent PVC cloth? That is 20 mils thick. How strong is this tarp? The average thickness of a credit card is about 30 mils, so the thickness of PVC waterproof cloth is not as thick as that of a credit card. Although almost. It is definitely stronger and more durable, which is why it is ideal for protective plastic barriers. It does not tear easily.
#3-Knitting
That is the weight and thickness of the coverage. There is one more factor to consider. This is weaving. A looser weave like a mesh tarp will not bear the weight of a tightly woven tarp. Canvas tarpaulin is one of the most durable tarpaulins on the market because cotton is tightly woven. Add a protective coating to make it waterproof and will not tear easily. The iron horse is one of the strongest tarpaulins on the market. Its strength is twice that of canvas tarpaulin. If you want a sturdy and durable tarp that can be durable, please choose an iron horse tarp.
#4 – Grommet position
To be strong, the tarp must be fixed to the load or material it protects. Look for the grommets, they should be placed evenly and not far apart. Make sure that the spacing of the tarps is at least every two feet.
#5-UV protection
Prolonged exposure to sunlight will decompose plastic or vinyl. If the tarp is treated to prevent ultraviolet rays, the tarp can be protected. When the tarp is not used, it is important to clean and dry the tarp. If you leave it outside 365 days a year, it will decompose faster than the tarp required.
