DC52D + Z deep-drawing grade galvanized steel sheet, where D represents cold-forming flat steel, C represents cold-rolled base steel, 52 represents serial number (one level higher in deep-drawing performance than DC51D), D represents hot-dip galvanizing, and Z represents pure zinc coating (30-350g). This is a popular high-end stamping steel solution.

Core Advantages
- Extreme Formability: R-value ≥ 1.8, suitable for complex forming processes such as deep drawing and drawing.
- Fatigue Resistance: Cycles > 500,000
- Welding Compatibility: CEV ≤ 0.18%, laser weld penetration consistency improved by 30%
- Coating Adhesion: Bend Test d = 0 (no peeling after 0T bend)
- Diverse Surfaces: Spangled or Zero Spangled to meet diverse aesthetic requirements
- Excellent Corrosion Resistance: The zinc layer provides rust protection, and the coating thickness can be adjusted depending on the application.
Applications
DC52D+Z galvanized steel, with its excellent plasticity and formability, is widely used in automotive manufacturing, home appliance production, building structures, and decoration, where complex forming or surface protection is required.
- Automotive Manufacturing: Door inner panels, floor panels, roof covers, fuel tanks/mufflers, heat shields, and wiring harness mounting brackets.
- High-end home appliances: Refrigerator, washing machine, air conditioner housings, drum washing machine drums, and microwave oven cavities.
- Architectural decoration: Factory walls, warehouse partitions, metal ceilings, elevator cars, and ventilation ducts.
- Other applications: Agricultural machinery panels, transportation equipment linings, electronic equipment housings, and electronic chassis.
DC52D Galvanized Steel Factory
Wanzhi Group‘s galvanized steel factory operates three continuous hot-dip galvanizing (CGL) lines with a monthly production capacity of 30,000 tons. We can produce galvanized steel coils and sheets in a variety of specifications and surface treatments. We also provide precision processing services such as cutting, roll forming, and spray coating.
