Flat webbing slings are a staple of general-purpose lifting — light, surface-friendly and cheap to ship. One of the first decisions when specifying them is whether you need a single-use (one-way, white) sling or a reusable one. Both are flat webbing slings, but they sit on different standards and very different duty cycles: single-use slings follow DIN 60005:2018-07 (5:1), while reusable slings follow EN 1492-1 (7:1). Written from a manufacturer and export source, this guide focuses on the single-use (one-way, white) sling and the specification details that decide whether it fits your one-way lifts.
1. What is a single-use (one-way / white) lifting sling?
A single-use lifting sling is an endless-loop flat webbing sling built for one trip. In the market it is called several names that all mean the same product: single-use sling, one-way sling, white sling, or disposable sling. It is typically made from 100% polyester or polypropylene yarn and built to DIN 60005:2018-07 (the German standard for disposable one-way textile slings, safety factor 5:1). Our standard range covers a working load limit of 1 t to 5 t, with custom capacities on request.
The load is lifted once, delivered, and the sling is left in place or discarded with the shipment — there is no return logistics to manage and no inspection history to track.
Why "white"? Single-use flat webbing slings are delivered in white as standard (other colors available on request). Many buyers simply ask for "white slings" or "one-way lifting slings" — they are the same product family.
Typical applications:
Steel, building materials and wood, welded mesh and tubing transport
Cargo loading and unloading, export and containerised one-way freight
Any shipment where the sling travels with the load and returning it is impractical or costly
2. What is a reusable webbing sling?
A reusable webbing sling is also a flat webbing sling made to EN 1492-1, but it is rated and built for repeated lifts. The two common constructions are eye-and-eye (a flat strap with a loop at each end) and endless (a continuous loop). After each lift it is recovered, inspected, and returned to service until it meets a retirement criterion.
3. Side-by-side comparison
The table assumes a comparable working load. Values are typical industry ranges; always follow the rigging plan and the manufacturer documentation.
| Dimension | Single-use (one-way / white) | Reusable |
|---|---|---|
| Material | Polyester / polypropylene | Polyester / polypropylene |
| Standard | DIN 60005:2018-07 | EN 1492-1 |
| Typical WLL | 1 t to 5 t (our standard range) | Broad range across the catalogue |
| Safety factor | 5:1 per DIN 60005:2018-07 (not adjustable) | 7:1 per EN 1492-1 |
| Intended duty | One trip | Various repeated lifts |
| Return logistics | None — ships with the load | Must be recovered and re-inspected |
| Unit cost | Lowest | Higher upfront, amortised over cycles |
| Color | White standard (other colors available) | EN 1492-1 color coding by WLL |
| Inspection | None — discarded after one trip | Regular, documented inspection |
| Best for | One-way steel / wood / cargo moves | Repeated lifting |
4. When to choose single-use slings
Single-use slings are ideal for steel, building, wood production, welded mesh, tubing transport, and cargo loading/unloading — especially where returning a reusable sling would be impractical or costly. If the sling does one job and then the shipment moves on, paying for a reusable sling you will never see again adds no value.
Because they are ultra-light and compact, single-use slings also cut freight cost when they travel with the load, and the disposable design avoids carrying a worn sling between sites — useful where cross-contamination matters (food, pharma and cleanroom-adjacent handling).
5. When to choose reusable slings
Choose reusable webbing slings when the same sling performs many lifts in one facility — production lines, warehouses, and repeated crane moves. The higher upfront cost is spread across hundreds of cycles, and a durable sling with reinforced eyes handles wear points better over time. Reusable slings also suit delicate or irregular loads where you want a sling that stays in your inventory and is inspected under your own procedure.
6. The cost break-even: how many trips before reusable wins?
Both types can be the cheaper option depending on how many times the sling is actually used. The decision rule is the number of trips the sling will make:
One trip — single-use is cheapest. Buying a reusable sling that is left on the load or returns empty is money spent on durability you never use.
Many trips at the same facility — reusable wins on whole-life cost. The higher purchase price is amortised across hundreds of cycles, and single-use slings are not built to survive that repeated handling.
The gray zone — roughly, if the sling would come back and be reused more than a handful of times, a reusable sling is the better buy. Price the break-even on your own data: divide the reusable sling's purchase price by the per-trip cost of a single-use sling (unit price plus any return logistics) — the result is the number of trips at which the reusable sling pays for itself.
Procurement tip: single-use slings shine where the sling would otherwise travel back empty. For specifications and color options, see the Single-Use Lifting Slings — product page.
7. Procurement checklist
Confirm the same basics before ordering a single-use webbing sling:
Working load limit (WLL) — match it to the heaviest lift, not the other way around.
Safety factor — single-use slings run 5:1 per DIN 60005:2018-07; reusable slings run 7:1 per EN 1492-1. A single-use sling quoting a 4:1 factor is not built to DIN 60005 and must not carry that standard's marking.
Marking and color — single-use slings are white webbing as standard (color is not a WLL indicator; always read the tag) and carry the orange "do not reuse" label required by DIN 60005; reusable slings use EN 1492-1 color coding by WLL. Confirm any custom colors.
Material and cover — 100% polyester or polypropylene, and any sleeve/cover requirement.
Certification — manufacturer certificate of conformity with tensile-test reports; real break strength exceeds the rated capacity.
8. Safety notes
Do not reuse a single-use sling. It ships without a reuse-inspection history, so you cannot verify its condition after the first trip. For repeat lifts, specify a reusable sling and keep it in your inspection program.
Do not mix single-use and reusable slings on the same lift point. Different elongation changes load sharing and can overload one sling. Keep one type per set.
9. FAQ
Are single-use lifting slings certified and safe?
Yes. They are manufactured to DIN 60005:2018-07 and backed by tensile-strength test reports; verified breaking strength exceeds the rated capacity (MBL ≥ 5 × WLL). They are rated for one trip rather than repeated use.
Can I reuse a single-use sling?
We advise against it. The sling is sold as a one-trip product without an inspection history, so its condition after the first lift is unverifiable — treat it as expired. If your process requires reuse, specify a reusable sling from the start and put it under your inspection program.
Do single-use slings come in colors other than white?
White is standard, but custom colors are available on request.

10. Technical notes
Single-use (one-way) slings in this guide are built to DIN 60005:2018-07 (the German standard for disposable one-way textile slings, safety factor 5:1); reusable flat webbing slings follow EN 1492-1 (Textile slings — Safety — Part 1: Flat woven webbing slings made of man-made fibres, for general purpose use, safety factor 7:1). This guide is for procurement education and does not replace the rigging plan or the manufacturer certification for your specific order.
