6 indicates that the steel wire rope is a 6-strand steel wire rope;37 indicates that there are 37 wires in each steel strand, which is a point contact structure.
Electro-galvanized is obtained by applying a power source and obtaining a plating layer by electrodeposition. The obtained plating layer is composed of fine pure zinc grains.
When its diameters from 0.5mm to 2mm,the cable remains very flexible, when its diameters is from 6mm to above, 6X7+FC steel wire rope become quite rigid.
