This is some tough material. Did some puncture and tear tests held up to and impressive amount of pull before failure. I cannot speak to the longevity, but it is installed outside as dock cushion re-covers, and will get the works from -25F to 110 above, humidity's all over the scale, and direct sunlight almost daily. Time will tell.
I have a metal frame that I think was to be used as a 1 car carport. Needless to say, the weak link was the cover. My neighbor had purchased a tarp from Tarps America and I was very impressed with the quality of materials and workmanship. I ordered one for the frame, it was shipped promptly and I received it undamaged within a short while. TA is a reputable company that takes care of their customers. I highly recommend them to anyone that needs a QUALITY covering.
We are using this tarp as a floor covering to protect the gym floor when the batting cage is in use. It's working perfectly. We needed a 20' x 60' area covered, so we split the tarp into two 20' x 30' pieces that weigh about 100 pounds each. It's easy enough to maneuver and store away, and provides a firm and secure footing for kids swinging a bat. The tarps came exactly when ordered, also!
Shipped fast. Excellent selection of product sizes.
