Hindalco's cold rolled sheets are precision-finished
to meet the international standards for tight
thickness, tolerance, flatness and dimensional
accuracy. Sound metallurgical properties for
further fabrication, anodising characteristics
and a blemish-free surface make it useful in
both commercial and general engineering applications.

Packing
Cold
rolled sheets are wrapped in HDPE and placed
on wooden pallets which have runners along and
across the length of the sheet. An angle board
is attached to the edges for edge protection,
plyboard is placed on the top and bottom of
the stack and the package is strapped with hoop
iron straps. Silica gel packets are used for
moisture protection.

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. |
