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.

Understanding the Colour Code
Synthetic slings typically follow a colour code system that signifies their material and capacity. While the exact colour code may differ between manufacturers, a typical pattern exists across the industry. 


Sling Cover Colour: Where colour is used to identify the WLL of the sling, the following system shall be used:

  • Violet: 1 tonne
  • Red: 5 tonne
  • Green: 2 tonne
  • Brown: 6 tonne
  • Yellow: 3 tonne
  • Blue: 8 tonne
  • Grey: 4 tonne
  • Orange: 10 tonne +


Slings may also have black stripes through the cover, indicating the WLL. The number of stripes shall represent the WLL with one stripe per one tonne. For example, four stripes indicates a WLL of 4 tonnes.

Label Cover: The colour of the label shall be used to identify the fibre material using the following colour code system

Green: Nylon                         Blue: Polyester                         Brown: Polypropylene                         Yellow: Amarid Polyamid
