Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer of high-quality lifting and rigging products. With over two decades of experience and an annual export value exceeding US$5 million, we serve global markets across North America, South America, Europe, Asia, Africa, and Oceania. Our Nylon Flat Woven Lifting Sling with a 4:1 Design Factor and 6000lb SWL (Safe Working Load) in Red Color Coding is engineered to deliver reliable performance for demanding lifting applications. This sling combines robust nylon construction, flat woven flexibility, and clear visual identification to ensure safe, efficient, and long-lasting service in workshops, warehouses, construction sites, and industrial facilities.
The 4:1 design factor means the sling's breaking strength is four times its safe working load, providing an extra margin of safety that meets industry standards. The 6000 lb SWL rating makes it suitable for medium-to-heavy lifting tasks, while the red color coding simplifies on-site identification and inventory management. Manufactured from high-tenacity nylon yarns, the flat woven structure resists abrasion, UV degradation, and most chemicals, ensuring durability even in harsh environments. Below, we detail the key specifications, features, and benefits of this product.

Technical Advantages
Our Nylon Flat Woven Lifting Sling is manufactured using advanced weaving technology that ensures consistent tension and uniform load distribution across the entire width. The edges are heat-sealed to prevent fraying, and the sling is treated with a UV inhibitor to resist sunlight degradation. Each sling is individually proof-tested to 2 times the SWL and bears a permanent identification tag showing the SWL, length, and serial number for traceability. The red color coding follows the international standard (ASME/OSHA) where red indicates 6000 lb capacity, making it easy to integrate into your existing color-coded lifting system.
Compared to polyester or polypropylene slings, nylon offers superior elongation (up to 10% at rated load), which provides shock absorption during lifts. This elasticity helps protect fragile loads and reduces peak forces on the crane or hoist. The flat woven construction also minimizes the risk of twisting or kinking, ensuring smooth operation even in tight spaces.
