Thép cạnh Corten

Kantstål Corten can be manufactured from multiple weathering steel grades, each with different strength levels, chemical compositions, and application focuses. ASTM A588 provides high-strength structural performance, S355J2W offers balanced European standard properties, while SPA-H and Q355NH are widely used in industrial and landscaping applications. Selecting the correct grade ensures optimal performance, độ bền, and aesthetic stability in outdoor environments.

Loại: Thép Corten

Sự miêu tả

Kantstål Corten refers to Corten steel edge strips or weathering steel flat bars used in landscaping, edging systems, and structural outdoor applications. These products are manufactured from different international weathering steel grades, each with slightly different chemical composition, sức mạnh cơ học, and corrosion performance.

Understanding the differences between common Corten steel grades is important for selecting the right material for landscape edging, garden borders, and outdoor structural projects.

Overview of Common Corten Steel Grades

Corten steel is not a single grade but a group of weathering steels defined by different international standards.

Major Grades Used in Kantstål Corten Products

ASTM A242
ASTM A588
Loại ASTM A606 4
S355J2W (Một tiêu chuẩn)
S355J0W
SPA-H (JIS standard)
Q355NH (Chinese standard)

Each grade is designed for atmospheric corrosion resistance but differs in strength level and application focus.
