Corten A Plates are high-strength, weather-resistant steel plates specifically designed to form a stable rust-like protective layer when exposed to atmospheric conditions. This natural protective coating eliminates the need for frequent painting or surface treatment, making Corten A an economical and long-lasting material for outdoor structural applications. Known for their superior corrosion resistance, durability, and aesthetic appeal, these plates are widely used in architectural structures, bridges, railway wagons, shipping containers, chimneys, and heavy industrial equipment.
Manufactured according to international standards such as ASTM A242, EN 10025-5, and other global specifications, Corten A Plates offer excellent weldability, machinability, and mechanical strength. Their ability to withstand harsh environmental conditions makes them a preferred choice for infrastructure, construction, power, and transportation industries worldwide, ensuring long service life with minimal maintenance costs.
Product Overview:-
Corten A Steel Plate is a type of weathering steel with phosphorus alloys of copper, nickel and chromium. Commonly used in shipbuilding, rolling stock, oil rigs, port construction, oil platforms, and other construction parts affected by hydrogen sulfide corrosion in petrochemical equipment Corten A steel plate is known for its corrosion resistance and it's a protective layer called 'patina'. when in moisture This is increasing the resistance The steel grade does not corrode when exposed to moisture, and the rust layer underneath protects the underlying steel, making it stronger. Corten A steel plates are aesthetically pleasing and have been used in a variety of construction projects including the design of bridges due to their high weather resistance.
Corten B Steel Plate is a great example of weather-resistant steel which has high tensile strength and high toughness. The plate is made up of a copper chromium alloy steel which is characterized by its outstanding resistance to atmospheric weathering as compared to other unalloyed steels. Corten B steel Plate chemical composition includes copper, chromium and phosphorus as they go into making this metal more resistant to corrosion. This type of steel develops a protective layer when exposed to atmospheric elements, which eliminates the need for maintenance like painting, making it a cost-effective alternative to other structural steels
