The bridge is an important auxiliary equipment for electric energy transmission, and can be used in indoor and outdoor environments. In order to prolong the service life of the bridge frame and prevent the bridge frame from rusting, the bridge frame manufacturers use many methods.

The more traditional and ancient method is to apply paint, paint on the surface of the bridge, and use paint to form a protective layer, so as to prevent the bridge from contacting with nature, and naturally there will be no rust. However, the paint is more likely to fall, and the paint needs to be repainted later, so this method costs more.

The same is to form a protective layer on the surface of the bridge, galvanizing technology is more popular. The bridge manufacturer performs hot-dip galvanizing on the surface of the bridge to form a galvanized layer, which can also prevent the bridge from rusting, and the galvanized layer will not fall off, which also saves a lot of trouble in later maintenance.

With the update and development of technology, the bridge has discovered a new method to prevent the bridge from rusting, that is, using fiberglass, aluminum alloy or SMC plastic to make the bridge. These materials are not rusty materials, used to make the bridge will not rust, very suitable!
