What is Weathering Steel?

Weathering or Corten steels are low alloy steels with high strength. It offers enhanced resistance to atmospheric corrosion. It can form a protective layer on its surface when exposed to weather elements like rain, humidity, and outdoor conditions. This acts as a barrier that protects the steels from further corrosion.

It also eliminates the need for painting or additional coatings. Weathering steel sheet is used in outdoor structural applications like bridges, buildings, sculptures, and facades. This is due to its mechanical properties, unique weathered appearance and low maintenance requirements.

A606 Weathering Steel Sheet

A606 COR-TEN weathering steel sheet is a high strength material designed to develop a rust-like surface patina if left unfinished, eliminating the need to paint the material and protecting the material from corrosion. A606 weathering steel is intended for welded, bolted, or riveted construction and common applications include landscaping, retaining walls, planter boxes, outdoor sculptures, building exteriors, electrical power poles, railcars, and other structures where high strength and enhanced corrosion resistance are required.

Difference Between Weathering Steel and Normal Steel?

  • Normal steel primarily consists of iron and carbon. It may also contain small amounts of other elements but lacks specific alloying elements to enhance corrosion resistance. Weathering Steel B Plate contains specific alloying elements like copper, chromium, nickel, and phosphorus.
  • Normal steel is susceptible to corrosion in atmospheric conditions. Thus, it requires painting or additional coatings to protect itself from rust and damage. Weathering Steel A Plate steels develops a natural patina on its surface when exposed to weather elements. This acts as a protective barrier and reduces the rate of further corrosion.
  • Weathering steel sheet has an aesthetically pleasing weathered appearance which normal steels don’t have.

FAQs for Weathering Steel Sheet

Weather resistant steel plates tend to be more expensive than regular carbon steel plates. This is due to the inclusion of specific alloying elements in the chemical composition, which enhance its corrosion resistance.

These alloying elements improve the atmospheric corrosion resistance of the steels by the development of a rust-like layer. This natural patina eliminates the need for painting or additional coatings which reduces maintenance costs in the long run. The cost-effectiveness of Atmospheric corrosion resistant steel plate comes from its lower maintenance requirements and extended service life.

Weathering plate rusts due to its chemical composition has a unique combination of alloying elements. The material forms a rustic layer on the surface when the plate is exposed to various weather elements. This, however, protects it from corrosion.

Painting Weathering Steel Plates for External Structures will interfere with the formation of this layer. Clients buy the plates due to the patina formation which helps with corrosion resistance and is aesthetically pleasing. Thus, the plate is not generally painted.

Weathering steel plates are highly durable, offering enhanced resistance to atmospheric corrosion. The natural rust-like patina reduces the need for frequent painting, lowering maintenance costs. With an aesthetically pleasing rustic appearance, they also provide high tensile strength and can be welded using conventional methods, making them ideal for a variety of outdoor and structural applications.

Corten Flat Sheets are available in different standard sizes in terms of their:

  • Length ranging between 2000 to 3000mm
  • Width can be within 1000 to 1500mm.
  • Thickness lies in the range of 1.5 to 10mm.

You can get customized sheets as per your project requirements from reputed suppliers like Corten Steel Tube.

The lifespan of corten roof sheets depends on environmental conditions, maintenance practices and thickness. Generally, it shows good long term performance and thus, is preferred over other material. On an average, corten roof sheets can last anywhere from 30 to 50 years or even longer, depending on its operating conditions.

Corten steel plates can be found in railroad coal wagons and other harsh condition applications. The name of Corten plate material is derived from its two main properties- corrosion resistance and tensile strength.

Yes, Weathering steel and Corten steel refer to the same type of material. “Corten” is a trademarked name often used to describe weathering steel, a group of steel alloys designed to develop a stable, rust-like patina when exposed to weather over time. This patina layer acts as a protective barrier, preventing further corrosion and eliminating the need for painting.
