Slings in Post Tensioning usually refer to the slights that are used in the construction business such as the lifting slings, the web slings, the round slings, the wire rope slings, the chain slings, the mesh slings, etc. Web slings are usually light weight as well as highly flexible, helping avoid shocks during loading. These are used in the maintenance sections of the manufacturing departments. Chain slings are mostly used when the conditions are on the rough side, especially in steel mills and foundries. They are made of high strength alloy steel that are resistant to both abrasion as well as cutting.
