SPCC Galvanized Steel Coil

SPCC galvanized steel coil is a high-quality cold-rolled steel that undergoes a hot-dip galvanizing process to provide enhanced corrosion resistance. The “SPCC” designation refers to a general-purpose cold-rolled carbon steel with good surface quality and moderate strength, commonly used for applications requiring good formability. The steel is zinc-coated (denoted by the “galvanized” term) to protect against corrosion, making it ideal for use in harsh or outdoor environments. SPCC galvanized steel coils are widely used in automotive, construction, home appliances, and electrical industries, offering excellent weldability, smooth surface finish, and resistance to corrosion. This makes it a reliable and durable material for products exposed to moisture, humidity, and other corrosive elements, where both strength and longevity are required.

Our SPCC Galvanized Steel Coil inventory is stored in ISO-certified warehouses equipped with humidity control (≤60% RH) to preserve zinc coating integrity. Strategically located near Shanghai and Guangzhou ports, facilities feature wide-span shelving systems to store coils vertically, preventing edge damage. Real-time RFID tracking enables efficient stock management, while 10-ton overhead cranes and coil grabbers ensure safe handling. Anti-static flooring and dust-proof zones minimize surface contamination. Partnering with global logistics networks, we guarantee lead times of 10–25 days for FOB/CIF shipments, supported by 24/7 digital inventory access and flexible JIT (Just-in-Time) delivery options.

The appearance of the coating is bright, meticulous, without sagging or wrinkles. Thickness inspection can use coating thickness gauge, the method is relatively simple. The thickness of the coating can also be obtained by converting the amount of zinc adhesion. For the bonding strength, a bending press can be used to bend the sample at 90-180°, and there should be no cracks or peeling of the coating. A heavy hammer can also be used to test, and the salt spray test and copper sulfate corrosion test can be done in batches.

SPCC Galvanized Steel Coil is manufactured to exact specifications, with thicknesses ranging from 0.3mm to 3.0mm, widths from 600mm to 1,500mm, and inner/outer diameters of 508–610mm and 1,200–1,800mm, respectively. Precision laser gauges and micrometers verify zinc coating uniformity (40–275g/m²) and adherence to JIS G3141, ASTM A653, and EN standards. Critical parameters like flatness, edge trim, and surface finish (e.g., regular spangle or minimal spangle) are inspected using automated optical systems. Mill test certificates (EN10204 3.1/3.2) validate mechanical properties, including yield strength (140–440MPa) and elongation rates, ensuring suitability for stamping, bending, and automotive applications.

SPCC Galvanized Steel Coil is meticulously packaged to safeguard against corrosion, scratches, and deformation during transit. Each coil is tightly wound and secured with rust-resistant steel straps, then encased in waterproof plastic film or coated paper to block moisture and contaminants. For enhanced protection, edges are covered with protective sleeves, and anti-corrosion VCI (Volatile Corrosion Inhibitor) paper is added upon request. Custom packaging solutions, including wooden pallets, steel crates, or customized bundle sizes, are available to align with industrial handling requirements. All packages are labeled with grade, thickness, width, and batch numbers, ensuring traceability and compliance with international freight regulations.
