Hot-dip galvanizing is a superior method for protecting steel from rust. Zinc’s ability to act as corrosion protection for iron and steel has been well known for centuries. Iron corrodes approximately 200 times faster than zinc, the corrosion of which in Sweden today is between 0.5 to 4 micrometers, depending on environmental conditions.
The entire steel structure is immersed in molten zinc. When the steel is dipped, zinc and iron form a compound that ensures very good adhesion. All surfaces are coated with zinc, including non-visible parts, such as inside steel profiles.
The thickness of the zinc layer depends on the chemical composition and material thickness of the steel. The material becomes virtually maintenance-free and has a very long service life.
The electrochemical action of zinc means that scratches and impact marks are to some extent self-healing.
In a life cycle perspective, hot-dip galvanized steel structures are a very good choice. Partly due to the long service life, and partly due to systems for recycling hot-dip galvanized material through remelting.
ABAS Protect hot-dip galvanizes its material according to European standard UNI-EN ISO 1461. This provides a zinc layer according to the table below. Hot-dip galvanizing of wire is carried out in accordance with European standards UNI-EN 10244-2 and UNI-EN 10245-2.
