Performance Features of Plastic Alloy Bridge Beams:
(1) A thick, dense layer of pure zinc covers the steel surface, preventing contact between the steel matrix and any corrosive solutions, thereby protecting the steel matrix from corrosion. In normal atmospheric conditions, a thin yet dense layer of zinc oxide forms on the zinc surface, which is hardly soluble in water, thus providing some protection to the steel matrix. If the zinc oxide combines with other atmospheric components to form insoluble zinc salts, the corrosion prevention becomes even more effective.
(2) Featuring an iron-zinc alloy layer with a dense structure, it demonstrates exceptional corrosion resistance in marine salt fog atmospheres and industrial environments.
(3) Due to its strong interdiffusion, zinc-iron alloys exhibit excellent wear resistance.
Due to zinc's excellent ductility, its alloy layer is firmly bonded to the steel substrate, allowing for various forming processes such as cold stamping, rolling, drawing, bending, etc., without damaging the coating.
(5) After hot-dipping galvanized steel joints, it is equivalent to a heat treatment process, which can effectively improve the mechanical properties of the steel matrix, eliminate stresses during the shaping and welding of steel components, and facilitate turning processing of steel joints.
