Description
Galvanized shingles are steel sheets with a zinc coating on the surface.
Galvanized roof tiles are steel sheets coated with a layer of zinc. Galvanizing is an economical and effective method of corrosion protection, and approximately half of the world's zinc production is used for this process.
Galvanized roof tiles are manufactured by coating the surface of a steel sheet with a metallic zinc layer, which prevents surface corrosion and prolongs its service life; this zinc-coated steel sheet is called galvanized steel sheet.
Product advantages
Galvanized shingles are widely used in various environments and have a long service life of corrosion protection, which depends on the environment.
Low processing costs, galvanized shingles have lower corrosion costs than other coatings.
Durability, in suburban environments, standard galvanized anti-corrosion coatings remain intact for more than 50 years without repair. In urban and marine areas, standard galvanized anti-corrosion coatings last up to 20 years without repair.
Reliability. The durability of the coating is relatively reliable because the galvanized coating is metallurgically bonded to the steel and becomes part of the hard surface.
The coating is tough and the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
Integrity protection
all parts of the plated component are galvanized, even in depressions, sharp corners and hidden areas.
Saving time and effort. Galvanizing is faster than other painting methods and avoids the time needed for on-site painting after installation.
Usesages
Galvanized tiles are mainly used in the construction, light industrial, automotive, agricultural, fishing and commercial sectors. The construction industry is mainly used in the manufacture of corrosion-resistant panels for industrial and civil engineering roofs, roof gratings, etc.; light industry for the housings of their manufacturing equipment, particular chimneys, kitchen utensils, etc. The automotive industry mainly for the manufacture of corrosion-resistant parts for vehicles; the agricultural, livestock and fishing industries mainly for the storage and transportation of grain, meat and seafood products, frozen processing equipment, etc.; the commercial sector is mainly used for the manufacture of galvanized products, frozen products, etc.; the commercial sector is mainly used for the storage of materials, packaging equipment, etc.
