2 thoughts on “Comparison of stainless steel copper door 201 with stainless steel copper door 304”

  1. The so -called stainless steel copper door is the imitation copper door. The surface material is treated with copper -plating color to achieve the appearance effect of the copper door.
    It can’t afford the copper door, buy a copper door, and the face.
    201 materials are easy to rust and are not suitable for coastal areas; 304 materials are suitable for coastal areas and are not easy to rust.
    The is too smart in TM, with falseness.
