Therefore, we can produce large quantities of this product.

It is a weather-resistant plate with an outer layer known as a patina, which provides additional corrosion protection. It’s an ideal material for weather resistance in conditions where natural alloys are excellent. The mill has set up facilities for making them

The Corten grade can be formed and welded. Most standard welding processes apply to it. The plates are rolled out from hot and cold rolling processes and annealed or heat treated to increase corrosion resistance.

During drawing, they are subjected to work hardening and are resistant to pitting and crevice corrosion in mild cyclic environments.

We are making our manufacturing team aware of the importance of quality. Our international customers comply with all regulations governing our production. We implement quality control systems at all production levels to ensure the highest quality of products.

Testing includes flaring, hardness, flattening, mechanical properties, intergranular corrosion, ultrasonic, and radiography testing.

Other tests can also be performed, such as a tensile test, a positive material identification test, a micro and macro test, and a chemical test. A third party inspects the quality of products by conducting a composition test, a hydro test, a destructive/nondestructive test, a pitting corrosion test, and a visual inspection. Among our services are MTC reports following EN 10204 3.1 or 3.2, NABL test reports, raw material test reports, mill test reports, quality assurance plans, heat treatment charts, stamping details, attested certificates, and warranty letters.

Commercial invoices, specification guides, disinfection reports, packing lists, net and gross weights, quantities, marks, and numbers, Certificates of Origin from legalized manufacturers, and information about chemical composition and hardness after heat treatment are also available.

Depending on the customer’s norms, we carefully design each package. Customers receive them in wooden boxes, pallets, and standard packaging. Depending on the customer’s norms, we carefully design each package.

In addition, a thin film of plastic prevents oxidation during shipping.

The CORTEN A PLATES are available at the most reasonable prices, and our technical staff and sales representatives are available to help our customers access their belongings

What is CORTEN A Plate?

Ratnaexpores.com has a long history of supplying quality industrial products since its establishment in 2005. Because the industry is providing excellent quality products manufactured by industry standards, it has gained appreciThe industry offers a comprehensive range of CORTEN A PLATES. hensive range of CORTEN A PLATES. To be able to meet the diverse requirements of the clients quickly, the industry exports and supplies Corten A PLATES in a variety of specifications. As a result, the product is supplied to global patrons at factory rates per several industry standards. Allows them to place their orders in large quantities. The Corten  A plates fall under the banner of ‘Corten  A Plates, which are highly acclaimed for their improved resistance to atmospheric corrosion compared to ordinary. In addition, these plates are also known as low alloys, owing to their chemical composition, which provides them with high tensile strength.


In addition to being stockholders of CORTEN A plates, we also stock plates with the following features:

1. Corrosion Resistance

A Corrosion Resistant Plate, UNI FE 510 D1K1, comprises alloys like Copper, Nickel, and higher Phosphorous content. The copper bonds to the oxidized shielding layer to improve its anticorrosive properties. Moreover, these plates rust slower than regular plates because the rusty layer helps slow down the speed rate of corrosion.

2. Weather Resistance

As a result of exposure to the atmosphere, weathering resistance plates like the NFA 35-502 E36 WA 4 develop a thin layer of oxide, known as “patina,” over the surface of the. The patina acts as a protective upper film that protects the underlying structure surface from harsh atmospheric conditions when the underlying structure is exposed to acute atmospheric conditions.

3. Paint Durability

There is no need to paint IRSM 41-97  plates to protect them from tarnishing. They form a corroded coating, orange or brown, which is mild. Thus, even without paint, these high-strength plates are safe and durable.

4. Weldability

As a result of the high content of carbon in EN10025-5 S355 J2WP  plates, these plates have superior mechanical properties and good welding capabilities. UNI FE 510 C1K1  plates can be welded using spot, submerged arc, and manual welding, making them easy to flange.

5. Unique Look

Under DIN 1.8945, corrosion-resistant plates can play a significant role in raising the aesthetic value of a tower. The oxidized finish of the corroded layer gives it an intriguing appearance.

6. High Tensile Strength

When used in large quantities, copper plays a pivotal role in raising both the tensile strength and the resiliency of ASTM A 242 TYPE 1 Corten plates due to its ability to initiate the rust-forming process on the structure.

Manufacturing process-

Plates are manufactured using a very high-quality alloy acquired from the best mills worldwide, which is then used efficiently in the production of the plates. This production process is strictly carried out under the supervision of a professional team with a good deal of experience in the same field and is certainly highly skilled.

Additionally, the quality control team is looking at the quality factor of the plates to supply delicious quality. Several product quality standards and industry norms or policies are being considered by manufacturers when producing leaves to enhance their quality. The industry has also improved the plate’s production process with the latest technology and modern tools.


The manufacturers use advanced tools to test the range of CORTEN A / B PLATES they produce. Tests include positive material identification, hardness tests, intergranular corrosion tests, pitting resistance tests, chemical/mechanical tests, flattening/flaming tests, macro/micro tests, etc. Consequently, suppliers must supply their customers with good or good-quality plates.

Documents provided

Yes, to assure the respective patrons that they are given the best possible quality plates that are 100% pure,

documents in the proof are provided. Documents include certificates of origin, material traceability reports, raw material testing reports, packaging lists, guarantee letters, commercial invoices, fumigation certificates, and heat treatment charts. In addition, they also offer test certification according to EN 10204/3.1B, a 100% radiography test report, a third-party test report, and a lab test report.

Delivering the plates

Delivery of ordered CORTEN A PLATES will depend on whether those are in stock. If the product runs out of stock, the time for plates to be delivered will depend on the product’s manufacturing according to the specifications requested. With the supplier’s connections to the best logistic partners, all shipping activities are quickly handled, and the product is delivered in good condition and on time.
