Copper production process

    After certain treatment in the process of making bronze, bronze doors do not need to put too much work surface color treatment can keep its original color, and the bronze doors of the internal use in the processing time is steel structure skeleton, so the bronze in the process of using not easy deformation, the use of time is very long. You can use paint, and out of a hundred years is not deformation.

    Time in the production of bronze is the result of many processes, like processing, corrosion resistance and practical processing and so on, these technologies are all other material categories do not have, and process these processing also directly determines the quality and life of bronze.
