As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in high-quality lifting solutions. Our Custom Polyester Round Sling with a working load limit (WLL) from 1 to 10 tons is designed to meet diverse industrial lifting needs. We offer free samples and dedicated technical support to ensure your satisfaction. With an annual export value exceeding US$5 million and shipments to major global markets, Boli is your reliable partner for safe and efficient lifting equipment.
Our polyester round slings are engineered for superior strength, flexibility, and durability. Unlike wire rope or chain slings, they protect delicate loads from scratches or damage. The endless loop design allows easy attachment to hooks, cranes, or other lifting devices. Each sling is manufactured with high-tenacity polyester yarns and a protective outer cover, providing excellent resistance to abrasion, UV rays, and most chemicals. The customizable options — including length, color, and special end fittings — make them suitable for a wide range of applications, from construction sites to warehouse logistics.
Key Features & Technical Specifications:
- High-Strength Polyester Core: Made from continuous filament yarns, ensuring consistent load distribution and minimal elongation under load.
- Durable Outer Cover: Woven sleeve protects the load-bearing core from wear, cuts, and environmental factors.
- WLL Range 1–10 Tons: Available in standard rated capacities; custom loads can be engineered upon request.
- Safety Factor: Standard 5:1 safety factor (6:1 optional). Each sling is individually tested before shipment.
- Color Coding: Standard industry color coding for easy identification of capacity (e.g., green for 1 ton, yellow for 2 tons, etc.). Custom colors are available.
- Free Sample: We provide free samples for evaluation. Just contact us with your requirements.
- Technical Support: Our experienced team offers guidance on selection, usage, inspection, and maintenance.

Frequently Asked Questions (FAQ):
Q1: What is the minimum order quantity for custom polyester round slings?
A: For standard sizes, there is no strict MOQ. For custom sizes or special colors, we typically require a minimum order of 10 pieces, but we can discuss based on your needs. Free samples are always available for evaluation.
Q2: How do I know the correct sling capacity for my lifting application?
A: The required WLL depends on the weight of the load, the type of hitch (vertical, choker, basket), and the angle of lift. Our technical support team can help you calculate the correct sling size. We also provide a detailed load chart upon request.
Q3: Are your slings tested before shipment?
A: Yes, each sling is individually proof-tested to 1.25 times the WLL (or as per customer specification) and visually inspected. We maintain traceability for every batch.
Q4: Can I get a free sample and what is the shipping cost?
A: Yes, free samples are provided. You only need to cover the shipping cost (or we can arrange collect shipping). Contact us with your address and preferred sling parameters.
Q5: What is the typical lead time for production?
A: For standard slings, lead time is 7–15 days. For custom orders, it may be 15–25 days, depending on quantity and specifications. We always confirm the schedule with you before production.
Q6: Do you offer technical support for sling selection and inspection?
A: Absolutely. Our team provides full technical support including selection guidance, usage instructions, and periodic inspection recommendations. We can also provide user manuals and safety guidelines.
Q7: Are the slings resistant to UV and chemicals?
A: Polyester has good resistance to UV radiation and most chemicals (except strong acids and alkalis). For specific chemical environments, please consult us for material compatibility advice.
Q8: Can I have custom printing or labeling on the sling?
A: Yes, we can add your company logo, WLL, or other identification on the sling label or directly on the outer cover. This is a common customization option.
