DC53D Galvanized Steel Benefit
- Excellent deep drawing performance: DC53D grade steel features high ductility and low yield strength, with an LDR of ≤2.5.
- Excellent corrosion resistance: A coating provides rust protection for the steel substrate. Coating thickness (20-350g) and coating material (+Z, +AZ, +ZAM) can be selected based on application requirements.
- Surface quality: Smooth and aesthetically pleasing, and various surface treatments such as painting and lamination are possible.
- Lightweighting: Thinner substrates result in lighter parts.
DC53D Galvanized Steel Applications
- Automotive body panels
- Chassis and structural parts
- Appliance and electronic product housings and interiors
- Building and infrastructure exterior walls and roofs
- Lightweight steel structures
- Power and energy equipment
