Our portable bridges are designed to allow the bridge to be completely erected on rollers from one side of the gap to be bridged and then launched across without the use of any support within the gap. It is particularly of use in providing access in far-flung areas and hilly terrain and also provides quick restoration of communication where existing road or bridge connectivity has been destroyed by natural disasters. Portable bridges also augment the road network in connecting remote locations in difficult terrains, particularly in the hilly areas e.g. for initiation of project by Independent Power Producers in Hydro sector in North eastern part of the country. Through this product we intend to enhance export potential in countries like Bangladesh, Nepal, Bhutan, Sri Lanka, Myanmar among others. As a part of our portable bridges portfolio, we offer (i) standard width (3.32 m) single lane bridge; (ii) extra wide (4.25 m) single lane bridge (steel deck); (iii) extra wide (4.25 m) improvised single lane bridge using 10’x 7’ Panel; (iv) double lane bridge (steel deck) with 10’X 7’ panel; and (v) suspension bridge.

Our portable bridges confirm to Global AASHTO (American Association of State Highway Transportation Officials) Standards and are supplied in hot dip galvanized condition. We have entered into a memorandum of understanding for supply of galvanized portable steel bridges with the Government of Odisha, Government of Chhattisgarh and for Project Himank of the Border Roads Organisation. According to the ICRA Report, the total domestic market for portable bridges is estimated to be ₹2,000-2,500 million in revenue size. In terms of capacity, our Company, which has around 60% market share, manufactured around 4,800 metric tonnes in Fiscal 2017. The bridges are made to order as the configuration of the bridge varies according to the bridge span and the load carrying capacity of the bridge. The bridge, manufactured using mainly steel, is assembled on site and is therefore also known as a portable bridge. (Source: ICRA Report). The engineering division has supplied sixty-seven (67) portable bridges during the Fiscal 2018, seventy four (74) portable bridges during the Fiscal 2017 and seventy (70) portable bridges in the Fiscal 2016 which indicated a decline of about 15% in monetary terms in the Fiscal 2018 due to reduction in market demand.

Our Company holds patents for stiffened steel deck system for single lane bridges and manufacture of double lane portable steel bridges which were awarded to it in the year 2011 and 2007, respectively. Further, two (2) more patent applications pertaining to Improvised Single Lane Steel bridge system and Improvised Steel Decking system are under processing for certification. This unit has an in-house Design department involved in continuous upgradation of its products to meet the changing requirements of prospective customers and at present working on development of assault bridges, cable gripper for suspension bridges and walk way attachment for portable steel bridges. To meet what we believe to be increasing demand for our portable bridge products, we have created additional production facilities at DEP which is expected to supply about ten (10) bridges during the current fiscal year. We manufactured what we believe to be the highest modular steel bridge in the world, at Khardung-la, Ladakh in Jammu & Kashmir, which was erected at an altitude of 5,602 meters by the Border Road Organisation and was listed in the Guinness Book of World Records in 1990.
