Evening ordered and delivered two days later. Very good! The knot necklace is made of galvanized steel wire and electrically. The capacity should be at 150 Kg. For my purposes perfectly adequate. The weight of the chain is relatively low, estimated between 100 ... 200 g per square meter. Well worth buying for those people who need larger quantities. I have 30 running meters. ordered and need this for the fabrication of chassis stands (folding) of wood for exhibition cages (small menageries) for our local club. To reach here Price (incl. Delivery) of 0.67 per m chain I've seen this chain size in any hardware store (there usually between 1 ... 2 per m). To this extent buy recommendation! Addendum: above price refers to the time of my purchase present offer of a provider. Providers and prices can change, so watch prices!
