USA Piping Solution is a distributor and supplier of corten steel products, also referred to as weathering steel. Corten Steel is special in the sense that it is created to withstand rust, when uncoated it develops a layer called patina on its surface. This patina is successful in stopping the further corrosion of the steel below.
We have a vast product line, which comprises corten steel seamless pipes & tubes, Corten steel Welded Pipes, and grades with specifications as ASTM A423 A Gr.1 tubes and ASTM A847 Hss Welded Square Pipe.

Our inventory of standard sizes, materials and types of pipes is diverse, thus we are able to deliver instantly to the world at affordable prices.
We manufacture high-quality Square Corten Steel Pipes, Hollow Corten Steel Pipes, Rectangular Corten Steel Pipes, and Round Corten Steel Pipes with various wall thicknesses with the sole purpose of having a strong pipeline use.
What are Corten Steel pipes and tubes?
Corten Steel pipes and tubes are produced out of various grades of weathering steels, which are named so due to their quality of weathering, and their ability to form the distinctive layer of oxide, or patina, on the surface. It is the distinctive identifier of this material; as it is exposed to the atmosphere, it will create a protective layer of the material that is thin and serves as a kind of coating against further oxidation.
These types of steel are used in other specialized uses like in Exhaust Pipe systems. An example of this is the ASTM A847 specification that identifies high-strength low alloys that can be welded and bolstered and used in the areas that demand high corrosion resistance and structural integrity. Our pipes and tubes are of high quality and have a nominal diameter of 1 inch to 6 inches and a wall thickness of 0.133 inches to 0.280 inches. The price list and specifications of our Grade 1 Corten Steel Pipe, Seamless Pipe and A847 Welded Pipe are available on request.

Applications of Corten Steel Pipes & Tubes
Corten steel is also referred to as weathering steel, it is mostly applied in the areas where its distinctive corrosion resistance and rustic character can be exploited. It is best suited to difficult outdoor and industrial conditions because of its capability to develop a protective patina.
Marine industries: Corten steel pipes and tubes find a great demand in the marine industry because they have very good weather resistance. It is used in the construction of ships and marine containers as well as offshore structures whose components are in constant contact with saltwater, humidity, and corrosion in the atmosphere. The rust coating (patina) that develops on the surface of the steel guarantees the structural integrity of the material over an extended time and in very harsh environments (coastal and open-sea).
Petrochemical and Oil & Gas Industries: Corten steel is used in the Petrochemical and the Oil & Gas Industries in case of pipelines and structural elements that are prone to the effects of the corrosive fumes and chemicals as well as the elements of nature. Although it is not the best choice when it comes to transporting highly corrosive liquids such as stainless steel, its strength and resistance to overall degradation in the atmosphere makes it ideal in:
- External Piping and Ducting: This is applicable in the open sections of refineries and processing plants.
- Structural Supports: Frames and support structures of storage tanks and platform where high strength and low maintenance are needed.
- Exhaust Systems: Corten steel can withstand high temperature and corrosion hence is an excellent choice in exhaust systems in the industry.
Food Processing Industries: Corten steel is not normally applied to food or beverage direct contact in the Food Processing Industries. The reason is that its typical patina is a loose layer of oxide that may fall off and pollute products. Rather, this industry is very strict with materials that are highly sanitary and which are non-reactive such as Stainless Steel (particularly, grade 304 and 316) so as to maintain cleanliness and avert product contamination.
