Strength Test

Introduction

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.

Hypothesis

The Superior Truck Tarps D-ring attachments are stronger than the typical industry tarps with sewn on D-Rings.

Experimental Approach

A strength test was conducted on 30 samples of each style of d-ring attachment using a Leister Examo 600F.

Results

  Weld (lbs) Sew (lbs)  
Average 378.667 288.467 31.2% Stronger

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.
