Zinc coating (Z) produced on both sides by hot-dip galvanizing extends the service life of the end product by protecting the steel from corrosion.
The continuous hot-dip galvanizing process offers a wide protection range from Z100 to Z600 in addition to a tight bond between the coating and the steel. These properties make zinc coatings well suitable to forming and demanding corrosive atmospheres.
The composition of zinc coating consists almost entirely of zinc (>99 percent ) and is lead free, resulting in finely crystallized zinc spangle that meets high requirements for visual appearance. The corrosion resistance provided by the zinc coating is in direct proportion to the coating's thickness. The Z600 coating (42 µm on both sides) can achieve a service life of up to 80 years. Therefore, in certain applications, batch galvanizing of finished components can be substituted by using Z450 or Z600 coated sheet steel thereby simplifying the overall process chain.
Because of the sacrificial nature of the zinc, the coating provides corrosion protection for areas of exposed steel surfaces, such as cutting edges and areas where coating has damaged (scratches, impacts, etc.). Full corrosion protection is also achieved in areas that have been heavily formed because the peeling tendency of low-friction and tightly bonded coating is low.
SSAB offers zinc coatings with different coating thicknesses, surface qualities and surface treatments to meet the demands of various applications.
