Electro Galvanized Steel (EG Steel)

Electro Galvanized Steel (EG Steel) is a premium cold-rolled steel coated with a thin, uniform layer of zinc through an advanced electroplating process. Unlike hot-dip galvanizing—where steel is immersed in molten zinc—electro-galvanizing uses controlled electrolysis to deposit zinc particles evenly across the surface.

This results in a smooth, bright, and dimensionally precise finish, making EG Steel ideal for applications that demand superior formability, surface aesthetics, and reliable corrosion resistance.

Its consistent quality and clean surface make EG Steel a preferred choice for precision manufacturing, decorative components, and electronic enclosures.

Specifications

Standard	JIS G3313
Grades	SECC, SECD, SECE
Coating Weight	10 GSM – 60 GSM
Thickness Range	0.25 mm – 2.3 mm
Width	Up to 1500 mm

Surface Treatments Available

Surface Treatment	Key Benefits
Anti-Fingerprint Phosphate (AFP)	Ideal for electronics and appliance panels; resists smudges, enhances appearance, and improves corrosion resistance.
Chromated	Protects against white rust and corrosion during storage and transport; suitable for direct use or as a base for further coating.
Phosphate	Improves adhesion of paints and top coatings; commonly used in automotive and engineered components prior to painting.

Technical Advantages

Uniform Zinc Coating Thickness	Precise control (typically 5–25 microns) ensures consistent corrosion protection and surface quality.
Excellent Adhesion	Zinc layer bonds at the molecular level, providing superior adhesion for paints, sealants, and powder coatings.
High Formability & Ductility	Retains cold-rolled steel properties, making it suitable for deep drawing, stamping, and complex bending operations.
Minimal Surface Roughness	Mirror-smooth surface enhances visual appeal and reduces friction in precision components.
Lower Zinc Consumption	Requires less zinc than hot-dip galvanizing, making it cost-effective and environmentally responsible without compromising protection.

Applications

• Automotive components
• Electrical panels and enclosures
• Home appliances
• Furniture and storage systems
• General engineering and fabricated parts

EG Steel is the material of choice for manufacturers seeking consistent quality, clean aesthetics, and dependable performance.
