The energy-saving steel cable tray using high corrosion resistance VCI (gas phase corrosion inhibition) bimetallic composite coating technology has high load strength and long-term resistance to salt spray and chemical gas corrosion, providing electrochemical cathodic. The energy-saving steel cable tray using high corrosion resistance VCI (gas phase corrosion inhibition) bimetallic composite coating technology has high load strength and long-term resistance to salt spray and chemical gas corrosion, providing electrochemical cathodic. The bridge frame has undergone VCI bimetallic coating surface anti-corrosion treatment, which has extremely strong corrosion resistance. Its advantages are as follows: 1. The VCI coating has good adhesion with the steel plate, making the adhesion of the coating layer reach zero level; 2. VCI anti.
