Corten Steel
Corten Steel Manufacturer
Corten Steel, also known as weathering steel, is a high-strength low-alloy steel designed to develop a stable protective patina when exposed to natural weather conditions. This self-protecting surface layer helps reduce corrosion and eliminates the need for regular painting, making Corten steel suitable for architectural, structural and outdoor applications.

Key Advantages
Self-Protecting Patina
Corten steel forms a stable oxide layer that slows further corrosion, reducing the need for traditional painting and maintenance.
High Strength Performance
As a HSLA steel, Corten provides excellent strength-to-weight ratio, allowing lighter structures while maintaining load-bearing capability.
Distinctive Appearance
The natural orange-brown patina creates a unique industrial aesthetic widely used in modern architecture and landscaping.

Processing Guide
Due to its alloy composition and weathering characteristics, Corten steel requires suitable fabrication methods to maintain appearance and structural performance.
Cutting
Laser cutting, plasma cutting and other CNC cutting methods can be used according to plate thickness and precision requirements.
01
Bending & Forming
Proper bending radius and controlled forming conditions help prevent cracking, especially for higher-strength Corten grades.
02
Welding
Specialized weathering steel welding consumables are recommended to ensure the weld area develops similar corrosion resistance and appearance as the base material.
03
Surface Treatment
Natural weathering typically requires several months to develop a stable patina. Accelerated pre-weathering treatment is available for projects requiring immediate appearance.
04
For customers who need ready-to-install Corten components, we provide customized fabrication services based on drawings, samples or technical requirements.
Available services include:
CNC laser and plasma cutting
Bending, drilling and forming
Welding and profile fabrication
Pre-rusting and sealing treatment
Pre-Rusting & Anti-Runoff Treatment:
Natural weathering may cause rust runoff during the initial patina formation stage. We provide factory pre-rusting and clear sealing treatment to stabilize the surface color and reduce staining risks on surrounding materials such as concrete and stone.
Quality Control & Certification
We maintain strict quality control throughout production to ensure Corten steel meets international standards and project requirements.
Our inspection process includes:
Chemical composition analysis
01
Mechanical property testing
02
Thickness and dimensional inspection
03
Surface quality inspection
04
Material Test Certificate (MTC) supply
05
Third-party inspection services from SGS, BV and other recognized inspection agencies are available upon request.
