Surface treatment method of steel grid cover plate for water collection well

The steel grid cover plate of the water collecting well is mainly used for the steel structure platform plate, the ditch cover plate, the tread plate of the steel ladder, the ceiling of the building, etc.

First, cold galvanizing, also known as cold galvanizing For electro-galvanizing, that is, the zinc salt solution is electrolyzed, so that iron ions and zinc ions are replaced and reflected. Generally speaking, no heating is required, and the amount of zinc is very small, and it is easy to rust in humid environment. If the cold galvanized water collecting well steel grille cover is used outdoors, it will rust after encountering rain, and it will rust in 2 to 3 months in a humid environment. The anti-rust effect is very poor. But the price is cheaper than hot-dip galvanized! 2. Hot-dip galvanizing 1. The service life is long. Generally, the service life of the hot-dip galvanizing well steel grille cover is 50-60 years. 2. Anti-rust and anti-corrosion, the steel grid cover plate of the collecting well is black after production, after grinding, pickling and then hot-dip galvanizing can play the role of anti-rust and anti-corrosion. 3. Reduce investment, the service life of the hot-dip galvanized water collecting well steel grille cover plate is greatly increased, thereby reducing the replacement, and virtually reducing the cost of the customer's purchase. 3. Painting and painting the steel grid cover of the water collection well is mainly for the surface treatment of the steel grid cover of the water collection well. When the steel grid cover of the water collection well is used for mechanical equipment, the The color and the color of the device are required to be consistent. In this way, we use spray paint for surface treatment. The processing cost of spray-painted water-collecting well steel grille cover is lower than that of hot-dip galvanizing, the rust-proof ability is moderate, and it is more afraid of wear, but spray-painting can choose a variety of colors.
