Tata Structura steel hollow sections manufactured by Tata Steel, command several techno-economic advantages over conventional steel sections. Tata Structura provides better compressive strength than the traditional structurals because of their lower slenderness ratio and higher yield strength.
With high torsional rigidity and compressive strength, these hollow sections are comparably more efficient than conventional steel sections. The excellent distribution of material around the axis of the square and rectangular steel hollow sections allows for remarkable strength qualities and thus offers decisive advantages in its applications. The smooth and uniform profile of the sections minimizes corrosion and facilitates easy, onsite fabrication to significantly enhance the aesthetics of structures. A higher strength to weight ratio credits these sections with nearly 20% reduction in the use of steel.
The versatility of these sections allows for a wide range of applications as industrial sheds and exhibition stalls to space frames and sign supporting structures. The sections can also be utilized for large span portal frames, amusement parks and playground equipments, guard rails for staircases, sports galleries, pedestrian walkovers, bridges and bus stands amongst other uses.
Advantages of Tata Structura larger sections are mentioned below:
Technical advantages
Higher Radius of gyration - More compressive strength - economical for column applications
Columns being lighter, reduce the seismic loads on the structure in case of earthquakes
Exceptionally high torsional strength - effective for space frames and bending members
Replacement of lattice girders - more space for use
Concrete can filled – for higher strength columns
Attributes
Liberty to designers to imagine and design Structures.
Significant enhancement in the aesthetic appeal as compared to conventional sections
Ease in fabrication leads to faster constructions and thus saving in Time factor.
Fully weldable across all regions of section.
Uniform mechanical properties and better corner profiles.
More open spaces in the total steel structure than the built up sections used structure
Usage in column applications in multi-storeyed buildings, industrial shed ,godowns , warehouse etc
Utilities like electricals /water supply etc can be concealed in the sections
