Selecting the Right Webbing Slings
Before you buy any web sling, you must always pay attention towards the properties of webbings and your work environment where they will be used.

The polyamide or nylon webbings, on the other hand, are better option when working with alkalis but they can be damaged by acids. The polypropylene webbings are only slightly affected by acids or alkalis but can be damaged by certain solvents, tars and paints. So, use web slings made of the right material for your required job.

The web sling should be long as well as strong enough for the load and the slinging method. Check the manufacturer's reference chart for knowing and comparing the capacity rating of webbing slings.

If you see the possibility of abrasion, heat generated by friction or cutting from edges or corners during the operation where web sling would be used, buy a sling fitted with protective sleeves or you may also use suitable packing.
