    Please, help and give me the Chinese equivalent of these UK steel standard:
    S275, S355, and SHS.

    Regards.

      Hello, the Chinese equivalent steels are:

      S275 = Q275,
      S355 = Q355.
      And the Chinese SHS standard is GB/T 6728: Cold forming hollow sectional steel for general structure
