Corten B Steel Plates & Sheets

Corten B Steel Plate Suppliers in India

Corten Steel Tube is a renowned producer and exporter of durable and strong Corten B Plates. These plates are available in standard and custom size, width, and wall-thickness as per the diverse needs of global industries. Corten B is weather resistant steel that is popularly suitable for heavy and load-bearing structures. It forms a protective layer when it comes in contact with atmospheric elements. Corten B contains several alloys such as nickel, carbon, manganese, and chromium that offer excellent workability and durability.

Corten B Plates have a better finish that does not require any maintenance like paint. The maintenance and painting is required only when the plates are wet for a longer time. We are manufacturing Corten B Plates that are highly resistive to corrosion, pitting, and oxidation. These are lightweight and offer an extended working life.

What is corten B plate ?

Corten B is a weathering steel plate belonging to the ASTM A588 steel specification. The steel can withstand higher atmospheric corrosion than regular carbon steel. The Corten B Steel Plates develop a protective layer of rust-like appearance which acts as a barrier against further corrosion. This weathered appearance adds a unique aesthetic appeal to structures and eliminates the need for additional surface treatments. Corten B Steel Plate shows a combination of strength, weather resistance and longevity and thus, it is a popular choice for various construction projects.

What is a cor-ten B plate used for?

Corten B Steel Plates are suitable for applications like bridges, buildings, facades, sculptures and architectural elements. It offers high strength, durability and aesthetic appeal due to its reddish brown layer. Due to the properties, Corten B has become a popular choice for projects that require functionality and visual appeal in outdoor environments.

FAQs for Corten B Steel Plate & Sheet

Can you bend a cor-10 grade B plate?

Cor-10 Grade B Plate can be bent using appropriate techniques and equipment. It has a higher strength and hardness compared to regular carbon steel, and thus is tougher to bend.

Is cor-ten B plate rust proof?

COR-TEN B Hot Rolled Steel Plates are not entirely rust-proof, but it exhibits excellent resistance to atmospheric corrosion. They develop a protective layer of rust-like appearance called patina. This provides effective protection against atmospheric corrosion but cannot resist rust completely. Regular maintenance will help preserve the integrity of the patina and prolong the lifespan of the plate.

What can I use instead of corten B sheet?

Some alternatives to Corten B sheet for outdoor applications with weather resistance are galvanized steel, stainless steel and aluminum sheets.

What is the difference between corten A and B?

The main difference between Corten A and B is in their chemical compositions and mechanical properties. Corten Steel Grade A Plate contains a higher percentage of cu, which enhances its corrosion resistance. Corten B has a slightly lower cu content and is used in industrial and heavy duty applications. Corten B shows higher strength and hardness than Corten A.
