20 Years Steel Stockist
We are a professional supplier with 18 years of export experience. We maintain a large stock of steel coils and produce high-quality stainless steel plates and corten steel processing.
Our product range includes carbon steel, wear plates, galvanized steel, and aluminum. We focus on long-term stability and guaranteed quality packaging.
One-stop Steel Supplier
High quality and reasonable prices for steel coils, sheets, and pipes.
Corten steel, also known as Weather Resistant steel or Atmospheric Corrosion Resistant steel, is a low-cost and highly effective material. It is classed as "self-protecting" steel due to its "patina" which results from surface oxidation during atmospheric exposure.
The surface will develop a rusted appearance over approximately 3 months. For specific building requirements, we offer accelerated rust processing in our workshop with a finish that maintains its color for 3-5 years.

Frequently Asked Questions
What makes Corten steel different from standard steel?
Corten steel is "self-protecting." It develops a stable rust-like patina on its surface when exposed to the weather, which acts as a protective layer and enhances corrosion resistance compared to standard steels.
How long does it take for the rust patina to form?
Naturally, it takes about 3 months for the protective oxide layer to develop. However, we can provide accelerated rust processing in our workshop if your project requires an immediate rusted finish.
What thickness ranges are available for Corten steel plates?
We offer cold-rolled sheets in the 0.3mm to 1.5mm range and hot-rolled plates from 1.6mm up to 40mm thickness.
Can Corten steel be used for structural applications?
Yes, it is widely used in high-strength structural applications including bridges, heavy equipment structures, railcars, mining truck frames, and crane booms to reduce weight while maintaining durability.
What international standards do your products comply with?
Our products comply with several global standards including ASTM (Corten A/B, A588), EN (S355J0W), JIS (SPA-H), and GB (09CuPCrNi-A).
What is the minimum order quantity (MOQ)?
Our minimum order quantity is 1 ton. For items currently in stock, we can even provide single sheets.
