Aluminium coils for rerolling into foils from 0.009-0.05m
GBS foil stock is produced from high-quality rolling ingots and
concast coils. Manufactured with sophisticated equipment, the foil
stock is free of surface and sub-surface defects. Matching
international quality standards, it can be rolled to thin gauges of
aluminium foil for a number of applications.
Stringent quality checks ensure a world-class range of sheets,
extrusions and foil products from Hindalco. Continuous upgrades and
process improvement enable it to keep pace with the demands of its
ever-growing markets.
