The advantages of hot dip galvanizing

THE ADVANTAGES OF HOT DIP GALVANIZING COMPARED TO OTHER COATING PROCEDURES OF METAL SURFACES

The hot dip galvanizing offers the best anti-corrosive protection, restricted only by the compliance with the specific technical norms.

• The procedure is more economical than other technologies, especially painting.
• The lifespan of the protective zinc layer is around 20 years, but it can reach even 50 years, in the right environment.
• All the surfaces that get in touch with the air are evenly covered.
• The hot dip galvanizing does not require a previous preparation of the surfaces.
• It secures the easy checking of the protected surfaces.
• The hot dip galvanizing, unlike other forms of protection, such as painting, has a better resistance to vibrations.
• The only standard in this field is SR EN ISO 1461-2009.

The hot dip galvanizing process lasts a few hours, while painting takes 2 days (including the drying periods in between the two layers).

• The cost of this procedure represents 30% of the cost of hot dip galvanizing; the cost of painting can reach 60% of the protection costs (including the preparation of the surface).
• The protective layer does not require maintenance, for the entire life span of the product.
• The hot dip galvanizing procedure does not use solvents hazardous to health and the environment, as it happens with painting and free re-painting.
• In case of fire, the zinc layer is not flammable.
• Hot dip galvanizing offers a protection which reduces pollution of the environment.
• The hot dip galvanizing products can be recycled. The hot dip galvanized steel can be recycled in electric ovens (EAF), where the volatized zinc is collected.
