Products Description
Corten steel square tubes are structural components made from weathering steel, known for their strength, unique aesthetic, and resistance to atmospheric corrosion. These tubes, often used in architecture, landscaping, and outdoor furniture, develop a protective rust layer when exposed to the elements, which prevents further corrosion and eliminates the need for painting. Their strength, durability, and distinctive appearance make them a popular choice for various applications.

Key Characteristics:
High Strength and Durability:
Corten steel, also known as weathering steel, is a high-strength, low-alloy steel that offers excellent structural integrity and load-bearing capacity.
Corrosion Resistance:
The protective rust layer (patina) that forms on the surface of Corten steel acts as a barrier against further corrosion, making it ideal for outdoor use.
Unique Aesthetic:
The rusty, earthy appearance of Corten steel is highly sought after in architectural and design applications, adding a distinctive and natural look.
Low Maintenance:
The self-protecting rust layer eliminates the need for painting or other protective coatings, reducing maintenance requirements.
Versatile Applications:
Corten steel square tubes are used in a wide range of applications, including architectural structures, fences, railings, landscaping elements, and outdoor furniture.
Good Weldability and Formability:
These tubes can be easily welded, cut, and formed, making them suitable for various fabrication processes.
Common Uses:
Architectural Structures:
Corten steel square tubes are used in building facades, columns, beams, and other structural components due to their strength, durability, and aesthetic appeal.
Landscaping:
They are popular for creating garden edging, retaining walls, planters, and other landscape features.
Outdoor Furniture:
Corten steel square tubes are used in the construction of benches, tables, and other outdoor furniture.
Fences and Railings:
Their strength and corrosion resistance make them suitable for creating durable and aesthetically pleasing fences and railings.




FAQ
Q: What is the description of corten steel?
A: Corten Steel (sometimes known as weathered steel) is a group of steel alloys that are often used in outdoor construction. Corten Steel was designed to eliminate the need for painting and if left outside, exposed to the elements, they will develop a rusted appearance in just a few months
Q: What is the ASTM standard for corten steel?
A: What is Corten Weathering Steel? Weathering steels are a family of ASTM specifications, as well as several trademarked specifications exhibiting similar corrosion-resistant properties. The ASTM specifications are A588, A242, A606-4, A847, A871-65 and A709-50W. The primary trademarked product is Cor-ten®.
Q: Is corten steel malleable?
A: Combination of elements: Combined with iron, manganese, and carbon, corten steel plates is more malleable and resistant to impact damage than other steel forms because of the high carbon content. Iron and carbon combine to make regular steel.
Q: What are the advantages of Corten steel?
A: The longevity and low maintenance nature of Corten Steel make it a highly cost-effective choice in the long run. Its durable nature means fewer replacements over time, resulting in cost savings. The absence of painting and ongoing maintenance costs also contribute to Corten's cost-effectiveness.
Q: What are the properties of Corten steel?
A: Corten stands out from the crowd thanks to its unique characteristics and a huge array of benefits. Its superior corrosion resistance, robust tensile strength, and cost-effectiveness over the long haul make it a highly desirable material for a wide range of projects.
