DC53D Galvanized Steel Applications
DC53D Galvanized Steel Benefit
- DC53D grade steel features high ductility and low yield strength, with an LDR of <=2.5.
- 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.
- Smooth and aesthetically pleasing, and various surface treatments such as painting and lamination are possible.
- Thinner substrates result in lighter parts.
