Product Overview
Double Wall Round Sling Sleeves are used for double-layer protection of round slings, heavy-duty lifting points, and high-wear contact surfaces. They are suitable for lifting sling manufacturers, steel-structure lifting projects, equipment handling companies, and industrial lifting accessory buyers. The double-layer structure separates inner-layer fitting from outer-layer abrasion protection, improving tear resistance and abrasion protection on the sling contact surface. It is suitable for bulk orders requiring 6,000-lb breaking strength, low elongation, and interlayer stability.

Key Features
Inner/Outer Double-Layer Protection
The inner layer follows the round sling while the wear-resistant outer fiber takes edge friction, keeping abrasion on the sleeve surface during bending, rotation and repeated contact.
Less-Than-7% Elongation Under Heavy Compression
The paired sleeve layers work with less than 7% elongation under compression, limiting interlayer shift and keeping pressure more even along the protected sling section.
6,000-lb Strength Across Edge-Friction Contact
The 6,000-lb breaking strength helps the sleeve hold its protective contact when the sling is pulled against a hard edge, reducing sleeve displacement at the loaded contact zone.
-40℃ to 120℃ Surface Range for Wet/Oily Cycles
The -40℃ to 120℃ service range and water/oil-resistant surface keep the sleeve in contact during wet, oily or heated lifting cycles and leave the outer face easier to wipe down after use.
Customization
Double Wall Round Sling Sleeves support customization for round sling diameter matching, protection length, width, thickness, double-layer fitting method, color, RAL color, stripe, weave, label, and supply form.
Quality Control & Testing
For Double Wall Round Sling Sleeves, production control starts with the double-layer sleeve structure, interlayer fit, tube opening and slitting accuracy. Width, thickness and protection length are checked against approved specifications so the sleeve covers the round sling without local shifting, tight spots or uneven wear areas.
Under ISO 9001 and ISO 14001 controlled procedures, inspection focuses on inner / outer layer alignment, tear-resistant surface condition, abrasion-facing contact area, edge finish, color or stripe consistency and batch traceability. The wear surface and sleeve position are checked before shipment to keep the protection area stable during repeated lifting use.

FAQ
Q: 1. Can Double Wall Round Sling Sleeves be supplied as finished samples first?
A: Yes. Usually 1–2 samples are made first to confirm sleeve size, double-layer structure, and protection length. After confirmation, the order can move into trial production or bulk production.
Q: 2. What is the usual starting quantity for the first bulk purchase?
A: Double-layer sleeves are finished protective parts. The first trial order is usually arranged at 300–500 pcs / size / style, and later orders can be expanded by project size combination.
Q: 3. How do you prevent shipping confusion in multi-size orders?
A: Each size, color, and protection length is assigned its own label and outer-carton mark. Shipment is packed and recorded separately by order version.
Q: 4. Can repeat orders be scheduled directly according to the original size?
A: Yes. Repeat orders can be produced according to the approved sample and order records. Regular repeat orders usually take 7–15 days, while multi-size or multi-process repeat orders are arranged according to the project plan.
