Corrosion of weathering steel sheet

Weathering steel sheet is produced by adding corrosion resistant elements such as copper and nickel to common carbon steel in production, which improves the corrosion resistance of weathering steel sheet. With the frequent occurrence of some bad weather, many steel plates and other building materials are damaged more and more. To reduce these losses, some building materials companies began to choose weathering steel sheet instead of ordinary steel, and achieved good application results. Weathering steel sheet in use will also produce some rust, below we follow weathering steel sheet manufacturers to learn this layer of rust.

Weathering steel sheet, also known as corrosion-resistant steel sheet, originated from Cotton steel in North America, is a series of low-alloy steel between ordinary steel and stainless steel. Weathering steel sheet is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel.

Weathering steel sheet has the characteristics of tenacity, plastic elongation, forming, welding and cutting, corrosion, high temperature, fatigue resistance and so on. Rust occurs in natural climate, which results in a dense oxide layer between the rust layer and the matrix. Because of the existence of this dense oxide film, oxygen and water in the atmosphere are prevented from infiltrating into the steel matrix, thus improving the atmospheric corrosion resistance, rustproof and corrosion resistant. Weathering steel sheet has higher atmospheric corrosion resistance than ordinary steel. Materials can be recycled, very low carbon and environmental protection. Steel parts are corrosion resistant, prolong life, reduce consumption and save energy. Green environmental protection does not need initial coating; it can reduce the use of fire-proof coating and fire-proof coating, thereby reducing pollution, shortening construction period, reducing costs and reducing maintenance. Weathering steel sheet is a kind of economic steel with "green environmental protection" and sustainable development.

Weathering steel sheet has outstanding visual expression. The corroded steel plate will change with time. Its color brightness and saturation are higher than the general building materials, so weathering steel sheet is easy to highlight in the background of green planting in gardens. In addition, the rough surface produced by steel corrosion makes the structure more volumetric and quality.

The corrosion of weathering steel sheet is different from that of ordinary steel plate. It will change color over time. Weathering steel sheet is also gradually used by artists, and has been applied in landscape and curtain walls of buildings. The weathering steel sheet produced by BBN steel is reliable in quality and has a long service life, and has won good comments from many old and new customers.
