The utility model relates to an anticorrosive board of two -sided complex for the construction of bridge culvert, including basic unit's steel sheet, the upper surface of basic unit's steel sheet and lower surface all complex have corrosion resistant plate and evanohm wearing layer, form the composite construction that top -down is evanohm wearing layer, corrosion resistant plate, the steel sheet corrosion resistant plate of basic unit and evanohm wearing layer in proper order, Q235 steel or Q345 steel are select to basic unit's steel sheet, corrosion resistant plate selects Q304 steel or Q316 steel, the gross thickness of anticorrosive panel is 2.0~8.0mm. The utility model discloses material itself belongs to environment -friendly products, the recoverable environmental contaminant that does not contain, and the security performance is good, have very high corrosion resistance and intensity, it is reliably durable, the long -life, it is little to have thermal expansion coefficient, and thermal conductivity is low, the various environment of the better adaptation of ability, material sexual valence relative altitude, does the anticorrosive cost reduction 20 of pure stainless steel of the same type compare 40%.
