Polishing Technology of A588 Weathering Steel Plate

A588 weather-resistant steel plate is an alloy material, which has the characteristics of strong atmospheric corrosion resistance, strong toughness, and rich and diverse colors. It is widely used in the construction of bridges and buildings, and its anti-rust durability has been greatly improved after restoration. At present, with the development of science and technology, the processing technology of A588 weathering steel plate is also constantly improving.

In order to ensure the performance of A588 weathering steel plate, after it has been stored for a period of time, it needs to be polished. In this regard, mechanical grinding and polishing technology is usually used to carry out corrosion resistance and preventive maintenance testing.

Firstly, the grinding process of A588 weathering steel plate mainly uses coarse and fine grinding machines to grind away the rust, dirt, and other impurities that accumulate on the surface of the weather resistant steel plate. After grinding, the surface of the weather resistant steel plate will become smooth, and any surface defects which may cause corrosion can be removed.

Secondly, the polishing process of A588 weathering steel plate mainly includes the following steps: first, the sheet metal is placed on the polishing machine and the polishing disc is loaded. After the polishing is started, the speed of the polishing disc needs to be adjusted until the surface of the sheet metal reaches the required gloss. For A588 weathering steel plate, it is required that the surface gloss shall not be lower than 75 on the 60° angle glossmeter.

Finally, the anti-corrosion and preventive maintenance testing is usually adopted for A588 weathering steel plate. This is an important process for long-term use of the plate. The surface of the plate is usually observed after the inspection to ensure that no corrosion is generated. Rust-inhibiting oil can be applied to the plate surface to prevent further corrosion.

The correct polishing process of A588 weather-resistant steel plate can not only meet the anti-corrosion effect of the steel plate, but also make the structural performance of the steel plate reach a better level. It also needs to be combined with other inspections and maintenance to ensure the rust resistance and durability of the steel plate.
