ASTM A653 JIS G3302 Hot Dipped Galvanized Steel Coils with Anti-Finger Surface for Appliances and Construction

１．Product Overview

ASTM A653 and JIS G3302 hot dipped galvanized steel coils are widely used in construction, home appliances, transportation equipment, industrial cabinets, and furniture manufacturing. The zinc coating provides effective corrosion protection, while anti-finger and chromated surface treatments improve handling, storage performance, and appearance quality.

Available in SGCC, SGCD, SGCE, SGCH, DX51D+Z, DX52D+Z, and DX53D+Z grades, these galvanized steel coils support forming, stamping, roll forming, and general fabrication requirements across multiple industries.

２．Technical Solution

The steel substrate is continuously hot-dip galvanized to form a protective zinc layer ranging from 40g/m² to 450g/m². The zinc coating acts as a sacrificial barrier that helps protect the steel from atmospheric corrosion.

Additional surface treatments including passivation, oiling, and anti-finger acrylic coating improve storage stability and reduce the risk of white rust during transportation and processing. Multiple spangle options allow manufacturers to select the most suitable appearance and coating structure for their application.

３．Specifications

４．Application

Construction applications include roofing sheets, roof structures, wall cladding systems, garage doors, and window blinds.

Household appliance applications include washing machines, refrigerators, televisions, air conditioners, ventilation systems, vacuum cleaners, and solar water heaters.

Transportation applications include vehicle ceilings, mufflers, exhaust heat shields, ship bulkheads, and highway safety barriers.

Industrial applications include electrical control cabinets, industrial refrigeration equipment, and vending machines.

Furniture applications include lampshades, counters, signboards, and medical equipment components.

５．Processing

The coils can be processed through slitting, cut-to-length, roll forming, bending, stamping, profiling, and fabrication.

Surface options such as anti-finger coating, chromated finish, and oiled finish can be selected according to storage conditions and downstream manufacturing requirements.

６．Advantages

• High zinc coating range from 40g/m² to 450g/m² supports different corrosion protection requirements.
• Multiple steel grades provide options for forming, drawing, and structural applications.
• Regular, minimized, big, and zero spangle surfaces meet various appearance requirements.
• Anti-finger treatment helps reduce fingerprints and improves storage performance.
• 508mm and 610mm coil IDs are compatible with common processing equipment.
• Widely recognized ASTM A653, JIS G3302, and EN10147 standards facilitate international project acceptance.

７．How to Choose

• Choose DX53D+Z when deep drawing and excellent formability are required.
• Choose SGCH full hard grade for applications requiring higher strength and rigidity.
• Select zinc coating levels according to environmental exposure conditions.
• Choose anti-finger treatment for appliance panels and visible building components.
• Select minimized or zero spangle when painting or decorative appearance is important.
• Confirm thickness, width, coating weight, spangle type, coil ID, and surface treatment before ordering.
