Why SEWPRO

Questions Buyers Ask

What does EN 1492-1 require?

It is the European standard for flat woven polyester slings: a 7:1 safety factor, colour coding by working load limit, and permanent labelling with WLL, length, material and a traceable batch number. Every sling we ship complies and carries a batch certificate on request.

Which colour should the eyes be?

EN 1492-1 codes violet 1 t, green 2 t, yellow 3 t, grey 4 t, red 5 t and brown 6 t and above. We can follow that code, or your own colour system if you sell under a private brand.

Why is the webbing 12 mm thick?

Thicker webbing spreads load across the eye and resists edge cutting on steel and concrete. All our standard capacities from 1 t to 6 t are built on 12 mm finished thickness.
