Grade 80 chains are used in many lifting operations and are preferred were the demands on ruggedness and flexibility are high. But, they are 'heavy' and they still are only as strong as the 'weakest link'. Because of that, CONSISTENT quality and regular inspections are of utmost importance.

Our chain components are manufactured under a ISO 9002 Quality System (SGS), meet European Specification EN 1677.

Furthermore: WE SERVICE WHAT WE SELL. We come to you and will do the inspections at your plant if you wish so. We do the repairs, we do ACTUAL proof testing, and we re-certify used chain slings... not only ours but others brands as well.
