Corten B Steel Plate Manufacturers in India

Corten Steel Tube is a leading manufacturer, supplier, and exporter as well as a formidable stockholder of a range of Weathering Resistant Plates, also known as Corten B Steel Plate. Fabricated to outperform regular steel plates, S355 J2G1W Steel Plates were primarily developed as maintenance-free alloy plates for heavyweight assemblies.

What is Corten B Steel Plate?

Corten B Steel Plates are roll-formed steel plates designed to resist corrosion through the formation of a protective rust layer, or patina, when exposed to the atmosphere. This patina shields the underlying steel from further corrosion, making it more durable than regular steel plates. Corten B Plates, such as BS 4360 WR 50 C Steel Plates, have low phosphorous content, making them a suitable alternative to other structural steels. Their unique properties make them ideal for various industries, offering long-lasting performance with minimal maintenance.

What is Cor-Ten B Plate Used For?

Cor-Ten B Plates are widely used in outdoor applications such as bridges, buildings, facades, sculptures, and other architectural elements. These plates offer high strength, excellent durability, and a unique reddish-brown patina that provides both corrosion resistance and aesthetic appeal. Their ability to combine functionality with visual charm makes them a popular choice for projects requiring long-lasting performance in outdoor environments.

Is Corten B Steel Plate Expensive? Why?

Yes, Corten B Steel Plate is relatively more expensive than standard carbon steel due to several reasons:

Alloying Elements: Corten B contains copper, phosphorus, nickel, and chromium, which enhance its corrosion resistance and weathering properties. These alloying elements are costlier than those in regular carbon steel.

Aesthetic Appeal: Its unique rustic appearance and popularity in architectural and structural projects increase its demand, influencing its price.

Specialized Manufacturing: The production process involves advanced techniques and treatments, which add to the overall cost.

Despite the higher price, its durability, low maintenance, and visual appeal make it a cost-effective choice for long-term applications.

FAQs for Corten B Steel Plate & Sheet

What is COR-TEN B?

Cor-ten B is a weather resistant steel which is better suited for heavy and load bearing structures. The material forms its own protective layer when exposed to atmospheric elements. Essentially, the top layer corrodes which then protects the steel beneath it.

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.
