Product Description
SGCC Galvanized Steel Coil – JIS G3302 | Factory Direct Supplier
Our SGCC Galvanized Steel Coil is manufactured strictly to the Japanese Industrial Standard (JIS G3302). This commercial-grade hot-dipped galvanized steel coil features a uniform zinc coating applied through a precise continuous galvanizing line. It offers consistent surface quality, excellent corrosion resistance, and outstanding formability, making it the ideal base material for electrical enclosures, roofing sheets, panels, and general fabrication.
We supply SGCC galvanized steel coils, a Japanese Industrial Standard (JIS G 3302) commercial-grade electro-galvanized steel widely used in forming, painting, and general fabrication. Featuring a uniform zinc coating applied through the electro-galvanizing process, this coil offers consistent surface quality, good corrosion resistance, and excellent paintability for cost-sensitive applications.
Core Features
Uniform Electro-Galvanized Coating: Provides consistent zinc layer thickness with smooth surface finish, ideal for subsequent painting or coating.
Good Corrosion Resistance: Suitable for indoor and mild atmospheric environments where moderate protection is required.
Excellent Formability and Weldability: Can be stamped, bent, and welded using standard fabrication techniques without coating damage.
Cost-Effective Material Solution: Balances performance and affordability for volume production and general industrial use.
Applications
Ideal for electrical enclosures, cabinet panels, home appliance housings, interior building components, lighting fixtures, and general-purpose metal fabrication.
We supply coils in various thicknesses, widths, and zinc coating weights (e.g., Z12–Z27), with options for slitting, leveling, oiling, and passivation treatment. Full certification compliant with JIS G 3302, ASTM A591, and related international standards is provided.
【Why Choose Our Factory?】

The line integrates online thickness monitoring and surface inspection systems, ensuring full-process quality control. Custom coil weight and ID/OD specifications are fully supported to meet diverse application requirements.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
【FAQ】
Q: What is the difference between SGCC and DX51D?
A: SGCC is a JIS standard designation for commercial grade galvanized steel, while DX51D follows the European EN standard. The chemical properties are essentially equivalent. We supply both upon request.
Q: Do you provide Mill Test Certificates (MTC)?
A: Yes, every batch is fully traceable and supplied with MTC to guarantee chemical composition and mechanical properties.
