A588 weather-resistant steel plate is a kind of steel with special properties, which requires special anti-rust treatment measures to ensure its service life. Weather-resistant steel plate, commonly known as atmospheric corrosion-resistant steel, is a steel plate that forms a protective coating on the surface of the steel to resist atmospheric erosion. The weathering process of weathering steel is a natural oxidation process.
In the environment of air or water, A588 weathering steel plate surface will form a layer of rust protection layer, which has self-healing ability, can resist atmospheric corrosion and prolong service life.
Common anticorrosion treatment methods of A588 weathering steel include hot dip galvanizing, paint coating, mechanical zinc plating, etching, flame spraying, etc.
1. Hot dip galvanizing: it is to treat the weathering steel plate with a layer of zinc, so as to achieve the purpose of anticorroding. In this way, the weathering steel plate can withstand moderate corrosive environments and prevent the atmosphere from corroding.
2. Paint coating: paint coating can cover up the zinc layer at the surface of weathering steel plate, prevent water, oxygen and other corrosive elements from corroding the atmospheric corrosion resistant steel, and the weathering steel plate can offer better anticorrosion effect.
3. Mechanical zinc plating: mechanical zinc plating is a kind of coating treatment which uses mechanical impact by applying a layer of zinc to the surface of the weathering steel plate to protect the surface from corrosion, rust and other destructive factors.
4. Etching: It can form a certain micro-roughness on the surface of the weathering steel plate. The micro-rough surface formed has better tear resistance and can prevent the steel plate from rusting.
5. Flame spraying: Flame sprayed coating with zinc or aluminum alloy powder can make the surface of weathering steel plate have good wear resistance and corrosion resistance.
Through the anti-rust treatment method of the above A588 weather-resistant steel plate, the weather-resistant steel plate can be effectively protected from corrosion, its service life can be extended, and the environmental pollution caused by rust can also be reduced.
