This chain is made from alloy steel heat treated and is recommended for overhead lifting purposes. Flints stock nominal size 8mm Grade 80 chain but we can supply other sizes to order from 6mm to 26mm. The chain is hard to cut so we supply it in selected lengths with a range of accessories to fit. We can also supply ready made chain systems with a shortening clutch so that onsite adjustments to the chain length can be quickly and simply made. The chain may be used at temperatures from -40°C to +200°C without effect on the strength. The chain is a natural black colour and finished with a glossy varnish. It must not be zinc plated or galvanised.
