[0021] As a preferred embodiment, the overall cross-section of the thin plate body 1 is a wave-shaped structure, and the cross-section formed by the flat plate portion 2 and the two groups of inclined plate portions 5 fixedly connected on both sides is an isosceles trapezoidal structure.

[0027] As a preferred embodiment, the reinforcing plates 3 in the adjacent shaping grooves 7 on the upper and lower surfaces of the thin plate body 1 are staggered, and a plurality of sets of through openings 4 are provided at parallel and equidistant ends of the reinforcing plates 3 close to the flat plate portion 2, and the through openings 4 are all isosceles triangle structures.

[0028] In this embodiment, if Figure 1 , Figure 3 and Figure 4 The staggered distribution of the reinforcing plate 3 can further enhance the overall compression resistance of the metal sheet body 1, and can also further reduce the probability of bending and deformation of the metal sheet body 1 in the width direction of the shaping groove 7. At the same time, the opening of the through-hole 4 can help reduce the probability of zinc liquid remaining on the surface of the metal sheet.
