The invention provides a gear rack with an anticorrosion structure. The gear rack with the anticorrosion structure comprises two strip plates (1) and multiple pin posts (2) arranged between the strip plates (1), wherein the pin posts (2) and the strip plates (1) are of a split structure. The gear rack with the anticorrosion structure can be used for effectively solving the corrosion problem of the gear rack transmission structure under outdoor and heavy-pollution region environment conditions, omitting the maintenance work of the gear rack, improving the use efficiency of equipment, avoiding the dependence on special anticorrosion materials to the greatest extent and greatly lowering the gear rack processing cost, and is suitable for large-area popularization and application.
