Product Overview
Our Electro and Hot-Dip Galvanized Steel Sheets are cold-rolled carbon steel coated with high-quality zinc layers for exceptional corrosion resistance and mechanical performance:
-
Electrogalvanized (EG/SECC): Zinc thickness of 5–30 µm via electroplating; retains steel strength (YS 140–550 MPa, TS 270–600 MPa)
-
Hot-Dip Galvanized (HDG): Zinc coating ranging 60–275 g/m² (10–40 µm); highly durable in harsh outdoor environments ß
Core Parameters & Grades
-
Standards: AISI, ASTM, DIN, JIS, GB, EN
-
Thickness: 0.12–6.00 mm
-
Width: 600–1,500 mm
-
Length: 1–12 m or customized
-
Grades for Forming:
-
DX51D to DX57D+Z (China/EN) – ideal for deep drawing, ductile, elongation 22–41%
-
SGCC / SECC variants – commercial to deep-drawing quality for appliances
-
S220GD to S550GD+Z – strength grades (220–550 MPa YS) for structural tasks
-
Unique Advantages
-
Long-term Corrosion Resistance
-
Electro-galvanized sheets pass 500–1,000 hrs salt spray tests
-
Hot-dip sheets with Z60–Z275 coatings hold up in urban and coastal settings
-
-
Excellent Formability & Surface Quality
-
ELONGATION ranges from 22% to 41%, bends to 0.5× thickness, with low roughness (Ra 0.4–1.5 µm)
-
-
Versatile Surface Treatments
-
Options include chromate, phosphoric treatments, oiling (Code C/S/P/Q/T/V/O/M) for improved corrosion resistance and paint adhesion
-
-
Range of Coating Styles
-
Choose between zero, minimized, or varied zinc spangle finishes to suit painting or decor needs
-
Where It Works Best
| Sector | Key Applications |
|---|---|
| Construction | Light steel framing (0.5–2 mm), roofing, cladding (AZ100–AZ200 HDG substrate) |
| Automotive | Body panels, door inners, chassis parts (0.7–1.5 mm SECC/SECD) |
| Appliances | Fridge liners, washing machine drums, HVAC ducts (0.5–2 mm SECE/SECF/SECC) |
| Specialty Use | Electrical cabinets (EMI shielding), solar mounts (≥20 µm HDG or Zn–Ni coatings) |
Systems often exceed durability expectations—architectural and industrial tanks, equipment housings, or building components—lasting significantly longer than non-galvanized steel.
