Why are the Colored Flat Lifting Slings So Thin?

The webbing sling manufacturer wholesale flat lifting slings at the best price. You can customize your required color, width and thickness of various flat webbing slings. Usually, the thickness of colored webbing sling is thinner than the common lifting slings. The thickness is determined by the number of layers of the strap. For slings made of AA-grade polyester silk, the default manufacturer produces two layers. If necessary, it can be thickened separately. , but for current use, 3 or 4 layers are generally not required. Even for large-scale industrial lifting, thickness is not the main consideration.

Thickness of Colored Flat Lifting Sling

Thin does not necessarily mean that the tensile force or quality of the flat sling is insufficient. After scientific tensile testing, it can be seen from the report that a sling with 6 or 7 times the breaking force can withstand 6 or 7 times the rated load of the sling. will break. Therefore, although the inspected and qualified product looks relatively thin, its tensile strength will not be affected by this, and its thickness also complies with the JB/T8521 machinery industry production standard.

In terms of thickness, you can choose white polypropylene lifting slings, which are 4-layer thick by default, and can also be requested to be 5-layers, and the thickness of a single layer will be larger than that of polyester slings. But its load range is only 1-10 tons, its tensile strength is slightly worse, and its acid and alkali resistance is better. In short, different types and materials of lifting ropes have different characteristics. Thickness is not the only reference standard for tensile performance. The thickness is different for different breaking forces and different tonnages.

Of course, the thickness also needs to be referenced. According to production standards of webbing sling manufacturer, the thickness of a single layer of straps must be ≥2mm, and the thickness of each layer of multi-layer lifting straps must be ≥1.2mm. On this basis, the thicker the better.
