[0024] It should be noted that the steel plate base body 1 involved in the present application is a rectangular piece, which can be other structural pieces such as a pipe or a column in actual application, and all are hot-dip galvanized pieces.

[0025] As shown in Figure 5 The surface of the steel plate base body 1 is provided with a groove 13, and the inside of the steel plate base body 1 is provided with a lightening hole 14.

[0026] As a preferred embodiment, the groove 13 is provided on the surface of the steel plate base body 1 in multiple and arranged in a matrix structure, so that the contact area of the galvanized layer 2 with the steel plate base body 1 can be increased when the galvanizing process is carried out, the thickness of the galvanized layer 2 is increased, and the performance of the galvanized piece is improved.

[0027] As a preferred embodiment, the lightening hole 14 is arranged at the broken end surface of the steel plate base body 1, and the arrangement path is staggered with the position of the carbon fiber structural piece, so that the overall weight of the galvanized piece is further reduced, facilitating transportation and use.
