Flat Eye & Eye Polyester Web Sling

Flat Eye To Eye Polyester Lifting Sling | 100% Polyester Web Sling | WLL 1T–50T

Flat Eye & Eye polyester web slings deliver dependable, high-strength lifting for general rigging and heavy industrial work. Woven from 100% high-tenacity polyester, the flat body spreads load evenly and protects delicate surfaces from damage, while the integrated eye ends offer fast, flexible rigging. Available with a 7:1 safety factor and certified to EN 1492-1 / ASME B30.9.

1. Product Overview

The Flat Eye & Eye Polyester Web Sling is a flat, endless-free lifting sling constructed from 100% high-strength industrial polyester webbing with a sewn loop (eye) at each end. Designed for horizontal, choker, and basket hitches, it combines the load-bearing power of synthetic web lifting with superior surface protection for the goods being handled.

Unlike chain or wire rope, the wide flat bearing surface distributes pressure evenly across the load, preventing edge pressure, surface scoring, and load deformation. The soft, non-marring polyester body makes it the first-choice lifting accessory for precision equipment, coated materials, polished steel, and packaged goods.

Every sling is manufactured with continuous-inspection weaving, double-stitched load-bearing eyes, and a permanently bonded identification label stating the WLL, batch number, and standard — fully traceable from yarn to finished product.

2. Key Features

• Load capacity — High-strength 100% polyester webbing with certified breaking strength; typical safety factor 7:1 (6:1 and 5:1 optional).

• Soft load protection — Wide flat bearing surface spreads pressure evenly, protecting painted, polished, and fragile surfaces from scratches and deformation.

• Lightweight & easy to handle — Up to 80% lighter than steel chain or wire rope of equal capacity, reducing rigging effort and operator fatigue.

• Durable & corrosion-free — Resists moisture, chemicals, and UV degradation; does not rust, corrode, or spark — safe for hazardous environments.

• Reinforced eye ends — Precision-stitched, reinforced eye loops give secure, quick connection to hooks, shackles, and crane hooks.

• Versatile rigging — Works with vertical, choker, and basket hitches; flexible body conforms to the load shape for stable lifts.

• Easy identification — Color-coded by WLL per EN 1492-1 for instant capacity identification on site.

• Complete capacity range — Full range 1T–50T (custom up to 【100】T) with lengths from 1m to 20m+.

3. Technical Specifications

4. Color Coding System (EN 1492-1)

Each capacity has a permanently woven identification color, allowing riggers to verify the safe working load at a glance:

5. Structure & Construction

• Flat woven body: 100% polyester warp yarns woven into a single flat belt with uniform width and thickness for even load distribution.

• Eye loops: precision-formed at both ends and closed with multi-pass box-stitching (zigzag + bartack) — the stitching is load-bearing and 100% inspected.

• Edge finish: heat-sealed / bound edges prevent fraying and yarn pull-out under repeated use.

• Label: woven into the body (not glued or printed), remaining legible for the full service life.

• Traceability: each sling carries a unique batch/serial number linked to raw-material and production records.

6. Applications

Suitable for general lifting, transport, and rigging in industries where load protection and operator safety matter most:

• Steel, aluminum and coil handling (surface-sensitive material)

• Machinery, equipment and mold installation

• Construction and precast concrete lifting

• Logistics, warehousing and container loading

• Shipbuilding, offshore and marine rigging

• Automotive, glass and fragile-goods handling

• Paper rolls, pipes, and packaged goods transport

7. Standards & Certifications

• Test certificates: breaking-force test, proof-load test report provided with each batch (【JZJC2026062808】)

8. Quality Control

• Incoming inspection: 100% polyester yarn tensile test on every batch of raw material.

• In-process control: continuous width/thickness monitoring during weaving and stitching.

• Proof loading: each sling proof-loaded to 【3】× WLL before packing.

• Breaking-force test: sample destructive testing per batch with test report.

• Visual & dimensional inspection by QC per EN 1492-1 rejection criteria.

• 100% inspection before packaging; export packing with moisture-proof wrapping.

9. Customization Options

• Capacity & dimensions: WLL, length, width, and eye length made to order.

• Color: standard EN 1492-1 coding or customer brand colors.

• Labeling: woven logo, capacity, barcode/QR, and custom text on request.

• Packaging: rolls, bundles, or individual polybags with labels (OEM/ODM welcome).

• Accessories: hooks, shackles, protective sleeves, and corner guards available.

• MOQ & lead time: MOQ 【10】 pcs; lead time 【1】 days after deposit (samples available).

10. Usage & Safety Instructions

• Inspect before each use: check for cuts, abrasion, broken stitches, chemical damage, and label legibility; discard damaged slings immediately.

• Apply rated angles: for basket hitches, derate capacity by 0.8 at 45°–60° and 1.0 at 90°; never exceed the WLL marked on the label.

• Avoid edge contact: use corner protectors when lifting sharp-edged loads.

• Never knot, twist, or shorten the sling; avoid dragging on rough surfaces.

• Do not use beyond -40°C to +100°C working temperature range.

• Store dry, away from direct sunlight, UV sources, and chemicals; keep off the ground.

• Retire slings showing wear or damage — the service life depends on usage conditions; annual inspection by a competent person is recommended.

11. FAQ

Q1: What does "Eye & Eye" mean?

It means the sling is a flat webbing belt with a sewn loop (eye) at each end. Each eye connects directly to a hook or shackle, so the sling can be used in vertical, choker, or basket hitches without extra hardware.

Q2: What safety factor do you use?

The standard safety factor is 7:1 (breaking strength is 7 times the WLL), meeting EN 1492-1 requirements. 6:1 and 5:1 are available on request.

Q3: What is the difference between a flat web sling and a round sling?

A flat web sling has a wide, flat bearing surface that spreads load over a larger area — ideal for protecting delicate surfaces. A round sling has a circular cross-section and is more flexible for choking odd-shaped loads. Both are made of polyester; the choice depends on the load shape and surface sensitivity.

Q4: Can you make custom lengths, widths, and capacities?

Yes. WLL, length, width, and eye length are fully customizable. Please provide your requirements, and we will confirm the design drawing before production.

Q5: Do you provide test certificates?

Yes. Each batch ships with a breaking-force test report and proof-load test certificate. Third-party inspection (SGS, BV, TÜV, etc.) is available on request.

Q6: What is your MOQ and lead time?

MOQ is 【10】 pcs per size. Lead time is 【1】 days for standard sizes after deposit confirmation; samples can be prepared within 【1】 days.

Q7: How should I store the slings?

Store in a dry, cool place away from direct sunlight, UV, and chemicals. Do not hang on sharp edges; keep slings clean and free from oil and dirt to extend service life.
