Corrosion protection. Easily.
Maintenance-free hot-dip galvanizing also has an economic advantage over other processes such as coatings. High follow-up costs due to maintenance are avoided and hot-dip galvanizing is usually already cheaper for the initial costs.
Prices for hot dip galvanizing are calculated based on weight, e.g. RSD per kilogram or RSD per ton. The price of galvanizing increases with a thinning material thickness, since thinner material thicknesses have a larger surface area in relation to their weight and therefore accept more zinc.
