SUMMARY
Bright Zinc plated steel shelves can develop rust even in cold storage conditions, such as 0-1°C, due to the failure of the zinc plating. Over a six-month period, the zinc coating may flake off, exposing the underlying steel to moisture. This phenomenon is likely caused by differing rates of thermal expansion and contraction between the zinc and steel, leading to cracks in the plating that allow moisture ingress and subsequent rust formation.
PREREQUISITES
- Understanding of corrosion processes in metals
- Knowledge of zinc plating and its protective properties
- Familiarity with thermal expansion principles
- Basic concepts of moisture control in storage environments
NEXT STEPS
- Research the effects of temperature fluctuations on metal coatings
- Learn about corrosion prevention techniques for steel
- Investigate alternative protective coatings for metal shelves
- Explore moisture control methods in refrigeration systems
USEFUL FOR
Manufacturers, engineers, and maintenance personnel involved in the design and storage of metal shelving systems, as well as anyone interested in preventing rust in cold storage environments.
