Grade M (40) Chain Assemblies

Grade M (40) Chain Assemblies to EN818-3

Finish: Self Colour / Hot Dip Galvanized to ISO 1461

Tested & Certified

Grade M (Grade 40) Chain Slings still have a prominent position within the lifting industry. Their ideal use are in areas of extreme temperature or acidic conditions, such as Foundries, Galvanizing plants etc. where it is not permissible to use Grade 8 / 10 Chain Slings, although within these extreme conditions, the W.L.L. should be reduced accordingly.

We have the ability to manufacture Chain Slings to customers individual requirements, conforming current standards and legislation.
