About Tata Structura

Tata Steel - Tubes Strategic Business Unit (SBU) manufactures Structural Tubes under the brand name of 'Tata Structura'. 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.

Besides bearing the trust and value of the Tata Steel brand name, Tata Structura Steel Hollow sections are advantageous from a techno-economic perspective. Structures made of Tata Structura Hollow Sections are lightweight and therefore more resistant to seismic forces. These ensure high structural durability and are preferred by architects and structural engineers for Airports, Metro & Railway stations, Malls, IT & Industrial complexes, Conveyor galleries, Solar support structures etc.

'Tata Structura' steel hollow sections are of four types -

The sections are manufactured up to a maximum size of 250x250 mm for square hollow sections, 300x200 mm for rectangular sections and 300 mm NB for circular sections. The thickness of these sections range between 2 - 10 mm.


The applications of Tata Structura have been classified under the following segments -


Tata Structura Steel Hollow Sections conform to IS: 4923 and IS: 1161 standards of manufacturing. The quality of each Tata Structura Steel Hollow Section undergoes strict scrutiny during the manufacturing process. It starts with slitting the strip edges, continues with speed, temperature control during the high frequency induction welding and is followed by online non-destructive eddy current testing directly after welding. Off-line drift and flattening tests are also conducted. This is all within the IS 9000 Quality Management System.

The 5 Cs of Tata Structura

  • Cost Effective
  • Corrosion Resistant
  • Concentric Strength
  • Convenience of Fabrication
  • Creativity


  • Uniform material strength - All our products come with a test certificate and the material strength is specifically mentioned
  • Uniform thickness, dimensions and length as per Indian specifications
  • 100% of the material is tested for any defects along the weld line by non-destructive testing method
  • Easy to weld, bend and fabricate because of high ductile steel
  • Long lasting and better resistance to corrosion because of high quality steel
  • Enhance the aesthetic quotient of a structure

Cost Efficiency

  • Up to 30% reduction in steel consumption as compared to conventional sections
  • Lower handling cost, transportation cost, overall fabrication and erection cost
  • Lower cutting cost because of less cross-sectional area
  • Lower welding cost due to direct connection without an additional gusset plate
  • Smooth profile and less exposed surface acts as formidable barrier to rust
  • Lesser painting and maintenance cost compared to traditional sections
  • The lower dead weight of Tata Structura helps in reducing the design load, thereby reducing the material cost of foundation
