12. We believe
India
A land united by different Cultures, Ideas,
Philosophies, Arts and Music
Is now destined to become the destination for
the modern architecture
At ISMT we believe we have a role to play
We present our UHS tubes for those who
dream to create a landmark
13. UHS Tubes
Ultra High Strength, Seamless Hot Rolled
Hollow Sections conforming to EN 10210
14. UHSTMApplications
Visible supporting columns (water cooled for fire
fighting or air conditioning purposes or concrete-
filled for fire safety purposes or to enhance load -
ability and ventilation system) for light bands and
glazed walls, as framing for:
• Wall elements
• Skeletons
• String boards
• Pedestals
• Sliding door system
• Railings
• Grilles
• Gates
• Door posts.

Other Applications
23. UHSTMAdvantages
• Wide Range of steel grades for most varied
application.
• Large range of sizes and longer length.
• Optimum building load capacity.
• Unrestricted weld ability.
• Visual appeal.
• Structural safety and reliability.
• Cost effectiveness reduced cross section, wall
thickness and thus dead weight.
• Small weld volumes.
• Savings in paint coating and corrosion protection
cost.
• Uniform connection and joints in columns, beams
and girder because outer dimension can be kept
constant.
• Option to install supply lines( Air conditioning,
electricity or water.

Shown below, for each grade of carbon steel provided for by EN 10210-1, are the chemical analyses and
mechanical properties.
25. UHSTMStructural Grades & Properties
Fine grain steel
Fine grain steel – chemical composition and mechanical properties
Shown below, for each grade of fine grain steel provided for by EN 10210-1, are the chemical
analyses and mechanical properties.
CE (IIW) maximum value 0.63%
26. Fine grain, high strength, quench and tempered steelsFine grain, high strength, quench and tempered steels
• UHS hollow sections made of fine grain, high strength steels in
• various sizes and thicknesses. These tubes find application in the construction of bridges,
• crane construction, offshore engineering, building construction, ship building and other areas
• where reduction of dead weight without any loss of load bearing capacity structure is critical.
• Typical characteristics of these tubes are high yield strengths and good toughness with the
• guarantee of chemistry that is suitable for welding. Tubes are produced as per following
• chemical analysis that guarantee the required mechanical properties which generally
• conform to EN 10297 specification
