Mazzella is dedicated to the fabrication of material handling products that meet or exceed current industry and government requirements (OSHA and AMSE B30.9). Our calibrated testing allows us to test components and finished slings to help assure the quality of our products. Proof-testing and certificates of test are available for all of our products when requested at time of order. All of our synthetic slings are tagged with the information currently required by OSHA and ASME B30.9.
