In the lifting and rigging industry, synthetic slings are indispensable for their versatility, strength and various applications. However, one aspect that often confuses users is the array of colours these slings come in. These colours are not merely aesthetic choices; they convey crucial information about the sling's material, capacity and best practices for usage. In this guide, we'll use our Know How to decode the significance of synthetic sling colours to help you make informed decisions in your lifting operations.
