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.
