What is SPCC coil?
SPCC is an abbreviation for Steel Plate Cold Commercial, referring to cold-rolled low-carbon steel plates/strips produced according to JIS G 3141 standards. They are delivered after room temperature rolling and annealing, and their core characteristics are a smooth surface, precise dimensions, and good cold formability.
What is the key difference between SPCC coil and hot-rolled coil (SPHC)?
SPHC is hot-rolled, with a rougher surface and lower precision, emphasizing strength and weldability, and is mostly used in load-bearing structures. SPCC is cold-rolled, with a smooth and bright surface, and a thickness tolerance within ±0.02mm, emphasizing formability and surface quality, suitable for decorative and precision components.
What is the core positioning of SPCC coil in the construction industry?
It is used in non-load-bearing structures, emphasizing lightweight, high precision, and easy painting. It is suitable for scenarios with high requirements for surface texture and dimensional consistency, such as decoration, enclosures, and auxiliary structures.
What are the main specification ranges of SPCC coil?
Thickness 0.15–3.2mm (commonly used in construction 0.3–1.5mm), width 600–2000mm, length 1000–6000mm, roll weight 3–10 tons, custom lengths available.
What is the chemical composition range of SPCC rolls?
Carbon ≤0.12%, Manganese ≤0.50%, Phosphorus ≤0.045%, Sulfur ≤0.050%. Low carbon content ensures weldability and formability, while impurity control ensures stable processing.
