Rectangular Square and Hollow Section

Rectangular Square and Hollow Section Confirming to IS 4923 / 1997

Gaurang Hollow Sections - Superior is a word that falls short when it comes to quality

Gaurang markets its product under the brand Gaurang (India) & GPL which covers MS Black, G.I. Round pipes and Hollow Sections both in Rectangular and Square Quality rolled on High Frequency Induct weld HFIW mills.

The Process

Structural Par Excellence
  • International quality raw material
  • Enhanced physical strenght provides decisive advantage
  • Formed at modern HFIW mil under strict quality control
Unique Strength & Economy
  • Increased tensile capacity because of concentric connection.
  • Increased compressive strenght because of higher radius of gyration./li>
  • Full strenght under bending moment due to superior torsional rigidity
  • Enhanced shear capacity.
  • Multi fold tensional capacity.
  • Lower wind drag
  • Better fire resistance
  • The best during earthquakes
Cost Benefit

The Hollow Sections are perfect substitute for conventional single and channel and the market is diversifying to adopt the sections for the reason of overall cost saving of 15%.In addition to this,the maintenance of these sections is very cheap and it has a better aestheticlook.
