Product Introduction

SGCC galvanized steel sheet: Suitable for appliance housings and construction applications.

Designed specifically for appliance housings, interior architecture, and general corrosion resistance applications, it offers excellent surface quality and formability while maintaining cost-effectiveness.

SGCC galvanized steel sheet utilizes a hot-dip galvanizing process on a cold-rolled substrate. The zinc layer provides effective cathodic protection, and its uniform coating structure and excellent adhesion ensure long service life in typical environments. This material offers excellent stamping performance and surface quality, making it an ideal choice for appliance manufacturing, interior decoration, and electrical cabinets.

Certifications and Key Benefits

JIS G 3302, ASTM A653 certified: Complies with GB/T 2518 standards.

Surface Advantages: Corrosion resistance is over 300% higher than that of ordinary cold-rolled steel.

Customized Sizes: Thickness 0.4-2.5mm (±0.03mm), Width 800-1250mm.

Minimum Order Quantity 2 tons: Available with chrome-free passivation, oil coating, or fingerprint-resistant finish.

Technical SpecificationsMechanical Properties

Material Composition:

Carbon (C): ≤0.12%

Manganese (Mn): ≤0.50%

Phosphorus (P): ≤0.035%

Sulfur (S): ≤0.035%

Zinc Layer: 40-180 g/m² (Z12-Z60)

Surface Treatment Options:

Chromium-Free Passivation: Environmentally friendly, suitable for subsequent painting

Oil Coating: Short-term rust protection, easy storage and transportation

Anti-Fingerprint Treatment: Improves tactile feel and prevents marks

Dimensional Tolerances

Applications

Home Appliance Manufacturing: Air conditioner housings, washing machine panels, microwave oven cabinets

Architectural Decoration: Ceilings, partition panels, interior doors and windows

Electronic and Electrical: Computer cases, distribution boxes, control cabinets

Office Equipment: Copier housings, filing cabinets, office partitions

Automotive Parts: Interior components, door panels, trunk linings

Processing Guidelines

Stamping: Suitable for deep drawing, with a die gap of 6%-8% of the material thickness.

Welding: Resistance welding is preferred; arc welding requires dedicated galvanized steel electrodes.

Bending: Minimum bend radius = 1.5 times the material thickness to avoid cracking of the zinc layer.

Coating: Degreasing is required before application. An epoxy primer + polyester topcoat system is recommended.

Quality Assurance

Zinc Coating Testing: Zinc coating thickness is determined by gravimetric method (ASTM A90)

Adhesion: Bend test verifies zinc coating bonding strength

Surface Quality: Visual inspection for zinc spangle uniformity and defects

Certification: ISO 9001:2015, RoHS, REACH compliant

Competitive Advantages

Cost-Effectiveness: 25% lower cost than post-galvanizing for the same level of protection

Production Efficiency: Eliminates post-galvanizing, shortening production cycle by 40%

Delivery Time: 5-8 days (minimum order quantity 2 tons)

Environmental Advantage: Chromium-free passivation process meets environmental requirements

Logistics and Compliance

Packaging: PE film + moisture-proof paper + wooden pallet, with corner protection

Storage: Indoor, dry environment to prevent interlayer slippage

Optional Processing: Slitting to specified lengths or pre-coating available upon request
