TATA STEEL TUBES SBU
Tata Steel – Tubes Strategic Business Unit (SBU) was established in 1985 after the merger of the
erstwhile Indian Tube Company Limited with Tata Steel. Tubes SBU has retained its leadership
position in the segments it operates, it has an installed production capacity of over 6, 00, 000
tons per annum and has ambitious plans to be a 1 Million ton player in the near future.
Introduction
BUSINESS VERTICALS
With continuous expansion and growth propositions on the anvil, Tubes SBU presently has three main
lines of business :
01. Structural 02. Conveyance 03. PrecisioniHigh quality hollow sections under
the brand “Tata Structura” cater
the Construction segment for load
bearing and aesthetic applications.
Galvanized and MS tubes under the
brand “Tata Pipes”cater the
irrigation borewell segment as well
as Plumbing applications for water
supply, fire hydrants and HVAC.
Manufactured with utmost
precision these tubes cater the high
end – Automotive applications as
well as boiler segment. They are
branded as “Tata Precision”.
Steel hollow sections are proving to be the most versatile and efficient form of structural steel for
construction and mechanical applications. Many of the iconic and most impressive structures in the
world today would not have been possible without hollow sections.
Now-a-days steel is being used more as exposed member to reveal its essence. This requires it to be
aesthetically appealing along with needed strength. The tubular form is most suited for such
application and at the same time proving to be inherently strong and efficient. It gives buildings a
better strength-to- weight ratio than those using comparable steel, concrete or timber products. In
construction, this strength-to-weight ratio reduces material usage and allows for greater spans. This
results in lightweight, airy structures that are aesthetically pleasing within our communities and
environments.
Steel Hollow
Sections are an
integral part
of modern
buildings :
Tata Steel pioneered the concept of Steel Hollow sections in India when it started manufacturing
square and rectangular sections in the late 1970’s. Tata Structura Steel Hollow sections are superior
in quality and are manufactured using raw materials that come from Tata Steel's world-class Hot
Strip Mill.
The world started noticing the arrival of the priemer product when the hollow sections product was
branded as “Tata Structura” in the year 2005. This innovative product helped the Indian Architects
and Structural engineers to realise their dreams of building aesthetically superiror structures on par
with International landmarks. Together , this revolution laid the foundation of a modern and
dynamic India .
Tata Structura :
- First of its kind in India

INSPIRED BY
NATURE
Sustainable development is key to the survival of the human
race, today’s best practises in construction industry warrants
the use of more sustainable materials to reduce the carbon foot
print.
Tata Steel has been a pioneer in adapting sustainable best
practises in all realms of operations.
It also strives to manufacture more sustainable innovative
products which will help the construction faternity.
Nature has mastered the art of sustainability and it inspires us
to innovate; for example : the ant which weighs 3-4 milligram
can carry 40-50 times its own weight, similarly the spider web is
so intricate and very strong..imilarly the spider web is so
intricate and very strong..
... introducing TATA STRUCTURA
Inspired by the availability of high strength materials in nature, Tata Steel is introducting a high
strength variant of Steel Hollow Sections called “Tata Structura 355”
Tata Structura 355 – has an enhanced yeild strength of min 355 Mpa on par with International
standards
The higher strength will help to minimise the quantity of steel there by saving cost and more
importantly help reduce the carbon foot print
Thus Tata Structura 355 is truly a sustainable product developed to aid the Architects and
enigneers in transforming the Indian Skyline with architectural wonders which are not only
good looking but are also made of sustainable materials.

STRUCTURAL ADVANTAGES FABRICATION AND
MAINTENANCE ADVANTAGES
Superior geometric properties of Structura Sections allows
better use of material
Lighter material attracts lesser cost for fabrication
and erection
Elimination of Gusset plates possible
Well rounded corners ensures maintaining uniform
coating thicknes
Dust accumulation avoided unlike open sections which
has crevices
High grade of steel with good amount of ductility ensures
lighter weight of stuctural system
Encourages use of Long Unsupported Lengths for
Columns and Beams
High torsional rigidity
A Comparison of the advantage in increase of yield strength in the performance of the structural element is
shown graphically in the figure below.
