We Provide

Hindalco are India's largest manufacturer of the entire range of flat rolled products. Our aluminium sheet is produced from our own cast slabs or continuous cast coils, rolled down to customised thickness, gauge and tolerances.

Hindalco’s rolled products are widely used in various segments such as Insulation, packaging, transportation, building and construction, electrical, defence and general engineering applications.

Our commitment to quality and service, along with extensive infrastructure, has made us a prime source for best-selling brands. Continuous improvements in manufacturing processes, practices and systems ensure that customers' needs and expectations are fully met.

We ensure efficiency and product quality by using state-of-the-art equipment and a strong research and development setup, supported by dedicated and motivated employees and the Oracle ERP system. Wagstaff Air Slip? slab casting technology is used to guarantee consistent quality and surface finish of stock feed, which in turn ensures quality finished products. Hindalco's cold rolled coils are precision-finished to match international standards. They have good shape, high tolerance, versatility and blemish-free surfaces. They are used in commercial and general engineering applications such as bus bodies, cladding and fan blades.

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.
