One of our customers sent us this Mexican, three quarter inch, heavy duty woven strap and buckles for testing. They thought they were getting a pretty good deal, but in our opinion, it’s very flimsy and in comparison tests Readback strapping and buckles achieve 40% higher system performance. So today let’s go back to the lab and take a look at the data so you can see how Redback’s superior weave patterns coatings and buckle geometry together provide some of the highest joint strengths and repeatable performance in the industry.
Using our newly calibrated load cell with accuracy of more than 99%, we pulled three linear tests of the Mexican strap at five inches per minute. The result was an average break strength of 2,768 pounds. Next, we pulled three linear tests of redback three quarter inch CW 7525 woven strapping and achieved an average break strength of 2,609 pounds, just slightly less than the Mexican product, but close enough for our main objective, which is to compare system strengths.
Straps are used in loop form. So for a true performance comparison, we pull straps in loop form with their recommended buckle. This is called a system test. In three consecutive tests of the Mexican strap, with their three quarter inch 157 gauge phosphated wire buckle, their strap slipped at 2,270 pounds, slipped at 2,491 pounds, and slipped at 2,398 pounds for an average system strength of just 2,263 pounds.
This translates to a 41% joint strength. In comparison Redback CW 7525 with redback BF 1940 B buckles achieved system strengths of 3,198 pounds, 3,123 pounds and 3,215 pounds for an average system strength of 3,178 pounds. This is a whopping 40% higher system strength than the Mexican product, and just another example of redback’s weave patterns, coatings and buckle geometry working together to provide some of the highest joint strength and repeatable performance in the industry.
