Some of the most popularly used synthetic web slings are manufactured with yarns that are polyester or nylon in nature.

You can also obtain wide widths with these slings. They also absorb shock very well. Some synthetic materials perform at a higher level than others depending on the environment or application involved.
The manufacturer places a marking on synthetic slings to indicate the type of web material used and the rated load for each hitch. A sling may also have a marking that indicates the stock number or manufacturer’s code, as well as the trademark or name of the manufacturer.
The nominal breaking strength of the material of the sling as well as other factors affecting its strength will determine the rated capacity of the synthetic sling.

As well, only a qualified individual should perform the necessary routine inspections of a sling – this may be based on how often the sling is used and the particular severity of its service activity and conditions.
Some of the inspection items that may be checked for and evaluated include:

* Cuts, holes, tears or snags
* Damage to end fittings
* Worn or broken stitching in load bearing splices
* Knots in any portion of the synthetic sling
