4. Packaging

  In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging：



According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.

Packing standard: according to the following national standard requirements (the parts beyond the requirements will be specified separately)

GB／T191 packaging-pictorial marking for handling of goods

GB／T4857 (all parts) basic test for transport packages

GB／T4879 rustproof packaging
