2019-02-18 15:03:01FEATURES
The grade 70 chains are extremely strong for their light weight and are mostly used for loading on platform trucks in the transportation field. They are also widely used on farms, for wood transportation, towing and construction. The ratio of great strength versus the weight of the grade 70 chains is achieved through a special heat treatment. They resist wear thanks to their exceptional hardness properties.
