Most truck tarps have D-rings that are sewn on with webbing. Superior Truck Tarps utilizes a patented RF (radio frequency) welding technique to attach the D-rings to the tarps.
The Superior Truck Tarps D-ring attachments are stronger than the typical industry tarps with sewn on D-Rings.
A strength test was conducted on 30 samples of each style of d-ring attachment using a Leister Examo 600F.
|Weld (lbs)||Sew (lbs)|
After conducting a one-way ANOVA test on the data set, the results showed that the RF weld method was able to withstand a higher amount of force.
