Viaduct Steel Structure

Steel structure pre-treatment: The steel components are painted with primer coating immediately after the shot blasting treatment and the interval between which is less than 30 seconds guaranteeing the strong adhesion film. The thickness of primer can be adjusted with different components to satisfy the anti corrosion requirement. The high quantity of surface treatment and strong primer adhesion together with normative fireproof coating guarantee the high efficient and long-term anti corrosion.
