Because of their special weathering qualities, Corten Steel A-plates—also known as ASTM A242—are a common choice for several uses. A type of weathering steel, corten A creates a protective layer of rust on its surface that stops more corrosion and eliminates the need for painting. This quality makes it a low-maintenance, aesthetically beautiful material.
Prized for their atmospheric corrosion resistance, Corten B steel plates are a form of weathering steel. These plates are made especially to get a stable, rust-like patina on their surface when left outside. Unlike regular steel plates, corten B plates generate this protective rust layer when they come into contact with the atmosphere. This quality qualifies them as a better choice in many different sectors.
Popular for many uses, Corten Steel Plates provide a number of benefits. Their natural corrosion resistance guarantees a long lifetime with minimum maintenance and is one of the main advantages. For structural projects including bridges, building facades, and other

Corten steel sheets are made from a special alloy steel containing copper, manganese, and nickel. This unique composition gives Corten steel exceptional resistance to weathering and corrosion. This is a popular choice for outdoor applications like bridges, railings, and sculptures.
Corten Steel Plates and Corten Steel Sheets differ mainly in thickness. Sheets are thinner, typically ranging from 0.5mm to 6mm, making them suitable for architectural cladding, decorative panels, and lightweight structures. Plates, on the other hand, are thicker, starting from 6mm and above, and are used in heavy-duty applications such as construction, bridges, marine structures, and industrial equipment. Despite the difference in thickness, both offer excellent corrosion resistance and develop a protective rust-like layer over time, eliminating the need for painting or coating.
