Which steel objects can be protected by zinc galvanizing?

Galvanizing is a process used to protect iron or steel from atmospheric corrosion and rusting by applying a zinc coating. While the process is most commonly associated with industrial-scale production, a variety of steel objects can be protected through these methods:12

• Sheet Steel: Much of the steel processed by the industry is in the form of cold-rolled strip or sheet, which is frequently coated using either hot-dip or electrolytic galvanizing lines.3
• Wire: Steel wire is commonly protected through continuous hot-dip galvanizing lines or by electrolytic coating in vats.23
• Structural and Formed Components: Through various hot-dip processes, cleaned iron or steel objects can be treated to form a protective zinc layer. This includes products that may undergo further manufacturing, such as those treated with the galvanneal process to improve weldability and abrasion resistance.23

The application method often depends on the object's requirements; for instance, while hot-dip processes provide a strong metallurgical bond, electrolytic deposition allows for precise control over coating thickness, which is beneficial for specific industrial applications.23
