WLL 300T Heavy Duty Round Slings | China Wristrong Supply
Australian & European standard heavy duty round slings WLL 300T from China manufactuer-Wristrong IndustryWristrong Industry is one of the most professional manufacturers in producing heavy duty / heavy lift round slings in China. These heavy duty lifting round slings are made from high tensile polyester yarns (5.6-8.0cN/dtex). Due to low moisture absorption, the break strength are basically the same with dry condition when it gets wet. This feature makes the polyester round slings ideal to opearate in moisture condition, like in rainy days, at seas,etc. Polyester round slings is also a good corrosion-resistant slings, can be resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids, not afraid of mold. That's why the polyester round slings are widely used in nearly every industrial sector wordwide. Each Wristrong Made 300Ton heavy lift round slings will be fufilled by proof test in designated lab and a proof test certificate will be issued and attached onto the heavy duty lifting sling packages. Wristrong China only use double ply sleeves:

The Advanges of Polyester Made Slings:
1. High strength , high strength fiber of 5.6-8.0cN/dtex, due to low moisture absorption, its wet strength and dry strength are basically the same. Impact-resistant strength is 4 times higher than nylon and 20 times higher than viscose fibers.
2. Exellent elasticity, elasticity close to wool, when elongated 5%-6%, almost complete recovery. Wrinkle resistance exceeds other fibers, that is, non-wrinkle, good dimensional stability. The elastic module is 22-141cN/dtex, 2-3 times higher than nylon.
3. Heat resistance, good water absorption, wear resistance than other natural fibers and synthetic fibers are better.
4. Good UV resistance, UV resistance is second only to acrylic.
5. Corrosion-resistant, can be resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids, not afraid of mold.
