we specialize in making honed tube for hydraulic cylinders, we CR steel just a UK registered company mainly for exporting, the workshop of mother group in mainland China specilizes in making such hydraulic products, if you are interested, you are welcome to be here to check everything, and our supply can be inspected before shipment either by yourself or any 3rd party is no problem
we wonder if you mean the workshop approved by any 3rd party, like the BV, SGS or Lloyds? in China, except the vessel making company need to get such certifiates, almost no other company need such approval, but our products can be approved and inspected by such company.
so, you pls see how to proceed on and if any more questions, pls contact us
Regards
Connie
