[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model aims to solve the problems that rainwater on the steel bridge cannot be quickly drained, dust stays on the top plate for a long time, increasing the cleaning difficulty, and the accumulation of rainwater and dust will corrode the steel bridge, reducing the service life of the steel bridge, and provides the following Figures 1 - 3A corrosion-resistant steel cable tray based on a protective layer is shown, including a bottom frame 1. Both sides of the bottom frame 1 are inclined planes. A cross plate 2 is arranged on the top of the bottom frame 1. On both sides of the top of the cross plate 2, a top plate 21 is fixedly connected. The top plate 21 is arched.

The arched shape of the top plate 21 and the inclined shape of the outer surface of the bottom frame 1. During daily use, when dust and rainwater fall on the top plate 21, they will slide down along the arc to both sides. After moving to both sides of the bottom frame 1, they will continue to slide down along the inclined plane. Due to the inclined and arched design, rainwater can be quickly drained away. At the same time, it can also reduce the staying time of dust on the surface, reduce the cleaning difficulty, avoid the accumulation of dust and rainwater on the surfaces of the top plate 21 and the bottom frame 1, reduce the corrosion of the steel cable tray by dust and rainwater, play a protective role, increase the service life of the steel cable tray.
