Tata Structura Properties

Tata Square section ranges from 25 * 25 mm to 250 * 250 mm , Rectangular sections ranges from 50*25 mm to 300*200 mm and circular section ranges from 15 mm NB to 350 mm NB .
Tata Structura is a perfect choice for engineers, architects and project managers today because of its Strength, Aesthetic characteristics and quality. It confirms to IS 4923 having minimum YST 310+.

Major Application areas are:

Industrial Sheds
Conveyor Gallery
Industrial support and products
Cold Storages
Material Storage Racks
Mine Roof support System
Pipe Racks
Airports
Bridges
Bus Stands, Car parking sheds
Automobile body
Sign supporting structures
Scaffoldings
Green house structures
Footbridges, etc
Due to the strength and characteristics of Tata Structura the total steel consumption reduces by about 30% compared to conventional structurals , and the strength increases due its higher strength to weight ratio.
