Everlast, a Hindalco brand launched in December
2002, is made of aluminium and is ideal for
all roofing and cladding needs. It is easy
to use, durable and economical to work with.
Using aluminium for roofing has many benefits.
Among these are the following:
|
|
Aluminium roofing sheets
are extremely light and have a high strength-to-weight
ratio. |
|
|
Aluminium is an increasingly
popular choice for use in installations
and buildings. It is corrosion-resistant
in almost any kind of environment. Even
in highly corrosive industrial environments,
it is resistant to fumes and vapours of
organic compounds and to chemicals like
ammonia, carbon dioxide and acids such
as hydrochloric acid, nitric acid and
sulphuric acid. Such corrosion resistance
gives the metal a long life and keeps
it looking good throughout its life. |
|
|
The shine and brightness of aluminium
livens its surroundings, and, because
it doesn't stain, discolour or rot, it
keeps its brightness and shine for a long
time. Aluminium corrugated sheets can
take a variety of finishes, colours and
textures, which protect them and further
enhance their appearance. |
 |
|
|
An alumunium structure can be easily
dismantled, transported and re-assembled
in a new location. |
|
|
Though the metal is a good conductor
of heat, its high reflectivity for radiant
heat and light (75 to 80 per cent when
new, 60 per cent after several years)
keeps the interiors of aluminium building
from five to eight degrees celsius cooler
in summer, while its low emission rate
cuts heat loss in winter. |
|
|
It is easy to maintain and wash. |

Aluminium recycling
has
been a common practice
since the early 1900s. The process
does not damage
the metal's structure.
Recycling aluminium cans,
foil and foil containers helps
in conserving energy. |
