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.

Fine grain, high strength, quench and tempered steels Fine 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
