Cold rolled steel plates are essential materials in manufacturing and construction worldwide, with each major industrial region maintaining specific standards to ensure quality and performance. Understanding these international specifications is crucial for material selection, procurement, and global compliance.
Chinese Standard: GB/T 708-2019
China’s national standard GB/T 708-2019 establishes comprehensive requirements for cold-rolled steel sheets and strips, covering:
-
Product classification and dimensional specifications
-
Permissible deviations in thickness, width, and length
-
Shape characteristics including flatness and camber
-
Technical requirements for surface quality and mechanical properties
This standard ensures consistent quality for China’s massive manufacturing sector and export market, with particular emphasis on dimensional precision for automotive and appliance applications.
British/European Standard: BS EN 10130:2006
The BS EN 10130:2006 standard specifies technical delivery conditions for cold-rolled low carbon steel flat products for cold forming, featuring:
-
Specific grades (DC01-DC07) with varying formability characteristics
-
Mechanical properties tailored for bending, drawing, and stamping operations
-
Strict surface quality requirements for exposed applications
-
Testing methods for verification of chemical composition and mechanical properties
This European norm is particularly valued for its focus on formability, making it ideal for automotive components and complex fabricated parts.
American Standard: ASTM A1008/A1008M-21
ASTM A1008/A1008M-21 establishes specifications for cold-rolled carbon structural steel plates, providing:
-
Multiple strength grades (SS, Type B, C; CS, Type A, B, C; DS, Type A, B, FS)
-
Comprehensive chemical composition limits
-
Mechanical property requirements including yield strength, tensile strength, and elongation
-
Dimensional tolerances aligned with North American manufacturing practices
This ASTM standard is widely referenced in construction, manufacturing, and industrial equipment sectors throughout North America.
Japanese Standard: JIS G 3141:2017
JIS G 3141:2017 delivers technical requirements for cold-rolled carbon steel sheets and strips, emphasizing:
-
Classification based on surface finish (commercial, drawing, deep drawing, extra deep drawing)
-
Strict dimensional accuracy and shape characteristics
-
Mechanical properties suitable for Japanese automotive and electronics industries
-
Comprehensive testing and inspection protocols
The Japanese standard is recognized for its rigorous quality control and suitability for high-precision manufacturing applications.
Global Standardization Trends
