Stren-Flex (Web and Round Slings)

At our company, we trust Stren-Flex for web and round slings because they deliver safety, strength, and reliability built on a foundation of quality craftsmanship and rigorous manufacturing standards. Stren-Flex produces their nylon and polyester web slings — as well as their high-performance roundslings — right here in the USA, using premium materials and high-tensile thread to meet or exceed safety standards from organizations like OSHA and ASME.   Their slings incorporate safety-core yarns woven into the webbing, providing a visible warning if the sling becomes worn or damaged — a feature we value highly because it helps protect our crews and customers on critical lifts.  

Moreover, Stren-Flex offers a variety of sling types — from flat web (eye-and-eye, vertical, basket, choker) to premium roundslings like their “Simian GT” and “Simian Ultra” lines — giving us the flexibility to choose the exact sling best suited for each job.   Their roundslings are designed for heavy lifting but remain lightweight and easy to handle, with strong protection against abrasion and wear, which is crucial in demanding industrial or rigging environments.
