SECC Electro-Galvanized Steel Coil
SECC stands for Electrolytically Galvanized Cold-Rolled Steel Coil. Through an electrolytic deposition process, a uniform and dense zinc layer is formed on the surface of cold-rolled steel sheets. This coating process is more precise and controllable, resulting in a thinner and more uniform coating.
Wanzhi Steel supplies SECC electrolytically galvanized steel coils in a full range of sizes, featuring advanced manufacturing processes and consistent performance.
Ensure product quality and transportation
SECC is an electrogalvanized steel coil classified as a general commercial-grade material under the Japanese JIS G3313 standard and typically features an anti-fingerprint treatment. While retaining the excellent formability of cold-rolled steel, it provides superior corrosion resistance and surface consistency, making it one of the foundational materials in modern industrial manufacturing that offers both performance and cost advantages.

SECC Characteristics
- Excellent Workability: SECC has nearly the same ductility as the base metal, making it well-suited for complex forming processes such as stamping, bending, stretching, and flanging.
- High Corrosion Resistance: The zinc coating on the surface of SECC protects the base metal; compared to ordinary cold-rolled steel, SECC offers 3 to 5 times better corrosion resistance in indoor environments.
- Superior Surface Quality: After fingerprint-resistant treatment, the SECC surface exhibits a uniform, fine, light gray matte finish, free of zinc bloom or bright spots, offering a modern and clean visual appearance.
- Versatile Surface: This surface can be used directly for exterior components and is compatible with secondary finishing processes such as spray painting, powder coating, lamination, or printing.
SECC Application Scenarios
- Electronics and Electrical Equipment: Computer cases, server enclosures, power supply enclosures, control panels, and inverter housings.
- Automotive Industry: Fuel tank mounting brackets, interior trim strips, instrument panel frames, filter housings.
- Construction and Hardware: Indoor drainage system components (e.g., rainwater pipe elbows), low-voltage distribution boxes, ventilation duct fittings, toolbox covers.
- Office and Residential Furniture: Steel filing cabinets, metal partitions for office desks, display racks, LED lighting housings.
Application Guidelines
For applications involving long-term exposure to high humidity, acidic or alkaline chemical environments, or those requiring high structural load-bearing capacity (e.g., heavy-duty outdoor brackets), we recommend prioritizing galvalume steel coils, hot-dip galvanized steel coils (SGCC), or pre-painted galvanized steel coils (PPGI).
SECC vs SGCC
| Item | SECC electro-galvanized steel coil | SGCC Hot-Dip Galvanized Steel Coil |
| Production Process | The zinc layer is deposited onto the substrate surface via electrolytic deposition. | High-temperature galvanizing, with molten zinc adhering to the substrate surface. |
| Coating Characteristics | Thin and uniform. | Thick zinc coating, Z30-Z275g/㎡ |
| Surface Appearance | Uniform light gray (fingerprint resistant treatment), no zinc speckles, extremely high flatness. | Bright silvery-white, with visible typical zinc crystal patterns. |
| Corrosion Resistance | General (suitable for dry indoor environments) | Excellent (suitable for humid, outdoor, or semi-outdoor environments) |
| Processing Performance | Higher elongation, more suitable for deep drawing and complex bending. | The coating is relatively hard; micro-cracks may occur during deep drawing. Suitable for general bending and rolling. |
| Typical Applications | Applications include computer cases, control panels, office furniture, electronic components, etc. | Applications include roofing panels, outdoor cabinets, and automotive chassis parts. |
