JIS G3141-2005 is the specification for cold-rolled carbon steel plates and strips in the Japanese Industrial Standard. This standard specifies the classification, dimensional requirements, chemical composition, mechanical properties, surface quality and other related requirements of cold-rolled steel plates and strips.
SPCC cold rolled steel can be classified differently according to its thickness and size, and also has specified dimensional requirements. The following is a general guide to the classification and dimensional requirements of SPCC cold rolled steel:
1. SPCC cold rolled steel classification:
a. SPCC-SD: Standard cold-rolled steel plate with grease-coated surface.
b. SPCC-SB: Bright cold-rolled steel plate, no grease coating on the surface, with good surface quality.
2. SPCC cold rolled steel size requirements:
a. Thickness range: usually 0.15mm to 3.2mm, generally 0.15mm to 3.2mm. Under certain circumstances, thicknesses beyond this range can also be provided.
b. Width range: usually 600mm to 2,000mm, the specific width depends on user needs.
c. Length range: usually 600mm to 12,000mm, the specific length is determined according to user needs.
It is important to note that specific dimensional requirements can be negotiated with the supplier or manufacturer at the time of ordering to meet the specific needs of the project or product.
In addition, SPCC cold rolled steel has other parameters and performance limitations, such as chemical composition, mechanical properties and surface quality. These limitations and requirements can be found and referenced in the JIS G3141-2005 standard.
