Climbing Webbing: Tape, Sewn Slings & Certification

Coiled climbing slings and runners in nylon and Dyneema webbing with carabiners on a rock face, showing flat and tubular webbing used in anchor systems.

Climbing tape, a sewn sling and a harness component are different purchasing items. Before comparing nylon, polyester or UHMWPE, identify the exact product, standard and manufacturer instructions required. General industrial webbing must not be substituted for specified climbing equipment.

EN 565 Tape and EN 566 Slings Are Different

UIAA identifies EN 565 with mountaineering tape and EN 566 with slings. Do not describe the finished-sling strength requirement as a universal requirement for every loose tape, and do not transfer an assembly certification to a roll of raw webbing.

The product’s certification and instructions define its intended use and limitations. A straight-pull material test does not reproduce every knot, seam, connector, edge or dynamic event in an equipment system.

Flat vs Tubular Climbing Webbing

Both constructions can be used in appropriately designed products. EDELRID’s PES SLING 16mm, for example, is a flat polyester sling listed with EN 566 and other certifications. This is evidence about that identified finished product, not an approval of generic flat polyester webbing.

Tubular construction can provide a different hand, thickness and handling behavior. Neither shape alone proves greater strength, abrasion resistance or suitability. Use the actual construction and test evidence. Knots and seams change the load path and must be assessed for the intended product.

Material Trade-offs

NylonExtension, moisture conditioning, abrasion and heat exposureThat elongation at break proves an assembly can safely arrest a fall
PolyesterLower moisture uptake, construction and finished-sling certificationThat all flat polyester is unsuitable for climbing
UHMWPE/hybridMass, surface friction, joining, heat and sustained loadingThat high fiber specific strength establishes a finished sling rating

What Technical Buyers Should Request

  • Product drawing and intended equipment-system function.
  • Applicable standards, revisions and required certification/qualification route.
  • Material identity, construction, width, thickness, tolerances and finish.
  • Relevant material results and final assembly test evidence.
  • Traceability, marking, inspection and retirement information from the equipment manufacturer.

TMG Component Sourcing

TMG manufactures webbing in Dongguan, China. A material discussion, GRS certificate or OEKO-TEX certificate does not establish a climbing-equipment certification. Send the component drawing and qualification requirements for assessment. Obtain complete equipment approval through the responsible finished-product manufacturer before use.

For general construction decisions read flat vs tubular webbing. For test interpretation read how to read a webbing test report.
