There are more and more galvanized posts on the market, so what is galvanized? Galvanizing generally refers to hot dip galvanizing, a process that coats steel with a layer of zinc to prevent corrosion. The steel is immersed in molten zinc at a temperature of around 460°C, which creates a metallurgical bond that forms the protective layer.
Role of hot dip galvanizing
The role of hot dip galvanizing is to provide corrosion protection to the steel substrate, helping to extend the life of the material. The process helps prevent rust and other forms of corrosion, which can cause structural damage to metal parts and lead to failure. Hot dip galvanizing is important for a range of applications including construction, transportation and infrastructure.
Use of hot dip galvanizing
Dip galvanizing is used to protect structural steel from corrosion, ensuring that buildings and other structures remain stable and safe. In the transportation industry, hot dip galvanizing helps prevent corrosion of vehicles, trailers, bridges and other infrastructure. In protecting metal materials from corrosion and ensuring the service life of various structures and components.
Standards of hot dip galvanizing
Hot dip galvanizing (HDG) standards vary by country and industry.
1. ASTM A123/A123M – Standard Specification for Zinc (Hot Dip Galvanized) Coatings on Iron and Steel Products
2. ISO 1461 – Hot dip galvanized coatings on iron and steel products – Specifications and test methods
3.BS EN ISO 1461 – Hot dip galvanized coatings on iron and steel articles – Specifications and test methods
These standards provide guidance on the thickness, composition and appearance of galvanized coatings and various test methods to ensure the quality of coatings.
