The invention provides a surface water removing device and a transportation system for profile steel. The surface water removing device for the profile steel includes a base, a transportation track and a first driving mechanism, and the transportation track is arranged on the base and used for receiving and transporting the profile steel in the transportation direction; the first end of the transportation direction of the transportation track is rotatably connected to the base; the first driving mechanism is connected with the second end of the transportation direction of the transportation track, and the first driving mechanism can drive the transportation track to rotate upwards relative to the base, so as to enable liquid on the profile steel on the transportation track to flow out. Thesurface water removing device for the profile steel can remove residual liquid on the profile steel, and thus the surface rust of the profile steel is effectively prevented, and the quality of profile steel products is improved.
