Steel bridge is the most widely used metal bridge in various industries at present

According to the material, the bridge is divided into metal bridge and non-metal bridge, and the metal bridge can also be divided into steel bridge, aluminum alloy bridge and stainless steel bridge. Steel bridge is the most widely used metal bridge in various industries at present. Because the price of steel plate is relatively cheap, and procurement is very convenient, large and small steel mills are everywhere, so they are welcomed and loved by major cable bridge manufacturers.
A characteristic of steel bridge is that it is easy to spot and rust after a long time in the environment of high temperature, high humidity and high corrosion. in order to solve this problem, a variety of bridge surface protection technologies have been produced. the commonly used surface protection technologies include galvanizing, hot-dip galvanizing, electrostatic powder spraying, anodizing and so on, but these technologies are not perfect for long-term placement in the natural environment.
Under this background, the latest VCI bimetallic coating technology was born, which is especially suitable for long-term outdoor perforated cable tray, which can replace the hot-dip galvanizing process, and then is much cheaper than the stainless steel bridge tray. 1. VCI bimetallic coating technology principle VCI bimetallic coating technology uses VCI antirust primer cathodic active protection principle and VCI topcoat shielding passive protection principle.
The steel bridge can resist the strong ultraviolet radiation and the corrosion of all kinds of gas outdoors. The corrosion curve of galvanized layer is not linear growth, but becomes a parabola.
2. The characteristics of VCI bimetallic coating technology VCI bimetallic coating technology has the following characteristics: 1: the coating has good adhesion and resistance to salt fog corrosion, which is especially suitable for steel bridges by the sea.
Feature 2: good heat resistance, adaptive temperature from 40 degrees below zero to 150 degrees above zero.
Feature 3: the thickness of the coating is 100-120um for wet film and 35-45um for dry film.
