In 1971 , a young skilled engineer hailing from Punjab, Shri. KamalNain Sharma Tuknait& Mrs. Pushpa K. Sharma Tuknait established the engineering company ‘M/S Industrial Bureau’. They manufactured various products such as Chemical Plant equipments, Pipelines, Heavy Structures, etc. In 1985, they developed a new product ‘Mild Steel Corrugated Cable Drums’ which was a superior alternative of ‘Wooden Cable Drums’. These drums were used by cable manufacturing companies as a packaging material for their product. The two key aspects making ‘Mild Steel Corrugated Cable Drums’ a viable option were their Stability and Environment Friendliness which in turn saved jungles due to their reusability.

 Today, the off-shore industry prefers steel drums instead of wooden, plywood, or plastic drums. With a continued increase in demand of the product, in 1997, a new manufacturing plant, ‘SANRAJ ENTERPRISES’ was established at Ambernath, MIDC B-60. It marked the commencement of exporting ‘Mild Steel Corrugated Cable Drums’. Following the footsteps of Late Shri. KamalNain Sharma Tuknait, Shri. Sanjeev Sharma Tuknait and Shri. Rajeev Sharma Tuknait further bore the responsibility for developing the group to achieve greater heights.

 In 2007, a new steel mill, ‘Industrial Steel Rolling Mill & Co.’ was set up which manufactures MS FLATS , MS T Angles, MS L Angles of various size and thickness. This initiative was to provide quality material for existing firms and to supply in steel market. In a short span of time, it achieved commendable recognition as a brand called ‘ISRO’. The brand received felicitation with an award and certificate in the presence of The Secretary – Ministry of Steel, Government of India, and UN resident, Co-ordinator, and UNDP Resident Representative, India at 8th Janpath , New Delhi.

Now, with over 50 years of profound experience , a new addition was made to the engineering group by beginning the manufacture of T Fence Post , Earthing Strips.   Raw materials for manufacturing T Fence Post is being Manufactured at Industrial Steel rolling mill and further activities are completed at Industrial Bureau for further dispatch . They can be used to support various types of wire or wire mesh. The end view of the post creates an obvious T shape. Certainly one of the main uses for T-posts is in fence construction, Bungalows , farms , gardens as security.
