PURE LEAD
Our
companies are competent enough in the supply of Pure Lead Ingot
which are being produced from Raw Lead Bullion / Remelted and
Secondary Lead Ingots / Lead Scraps through Pyrometallurgical
process. The strength we have in our Refining Process is the
purity Level we maintain minimum at 99.97% by weight but
achieves purity level of 99.985% in most of cases.
In our process by our experience we adopt many such features
which ensure Dross-free & smooth top surface of each ingots. We
dispatch after staking of 42 ingots in one bundle duly striped.

Our Quality is tested by
Our modern quality control Laboratory consists of Optical
Emission Spectrometer (OES) of Spectro Germany make & Atomic
Absorption Spectrometer (AAS). Our manufacturing operations to
produce Pure Lead Metal / Lead Alloy, Lead Oxides (Litharge, Red
Lead & Lead Sub-Oxide), Lead Products (Lead Sheets, Lead Pipes’
plates, wires etc.) are controlled round the clock by
experienced Chemists & Q.C. Supervisors.
Gravita follows strict quality standards in all areas of
operation right from selection of raw material to ultimate
dispatch to its valued customers.
One of the strengths of Gravita is our highly equipped R&D
laboratories and our broad technical competence within
production of Lead & Lead Products. Our foundry Lead customers
have full access to our extensive range of technical services
designed to meet their needs.
Gravita laboratory is equipped with latest technology analyzing
equipments like Optical Emission Spectrometer, Atomic Absorption
Spectrometer.
Our
manufacturing operations are driven by quality, from the way
they operate, to the customer service standards they set and the
products they deliver.
Each heat is being analyzed prior to its pouring Lead into the
moulds to ensure proper chemistry, grain size & dross content of
the Lead. All elements are controlled within specified limits
and proper records are being maintained. Each heat is being
assigned a unique batch no which is also marked every relevant
ingot to ensure complete traceability at a later stage.
In addition to in-process inspection, a highly experienced and
dedicated team ensures complete adherence to the most precise
standards. Experts are involved right from choosing the highest
quality raw material to application of various techniques to
ensure the product’s confirmation to the highest quality
standards.
We
focus on quality, which makes us to win new opportunities in an
increasingly competitive global marketplace. We identify areas
for improvement within our quality checks at every stage of
manufacturing process to provide our customers with the best
