In a global showcase of advantages of using stainless steel in the corrosion-prone coastal areas, China has built a 55 km long Hongkong – Zhuhai – Macau bridge using around 10,000 tonnes of stainless steel, among other metals. Chinese President Mr Xi Jinping inaugurated the bridge on October 23, 2018 for public use. The bridge has used over 10,000 tonnes of nickel containing duplex stainless steel reinforcement bars in construction at critical corrosive zones. This is expected to ensure a projected life of 120 years for the structure, which will be under constant corrosive attack of saline sea water. This landmark structure is a bridge tunnel system consisting of a series of three cable stayed bridges, one 6.7 km under sea tunnel, and 3 artificial islands. The bridge is an engineering marvel constructed over 9 years, at an estimated cost of $20 billion.

Collapse in the railways infrastructure is leading to significant disruptions and economic losses. The tragic pedestrian bridge collapse at the Andheri station, barely nine months after the railway bridge stampede causing 23 deaths at Elphinstone Road in Mumbai, could have been avoided by adopting stainless steel for creating such long term social infrastructure, especially foot-over bridges and overbrigdes. Indian Stainless Steel Development Association (ISSDA), country’s apex stainless steel body has reiterated importance of using stainless steel for social infrastructures like bridges, railway lines, etc. to drastically minimise loss of life and finances.

“Considering 50% of the Indian Railway bridges, out of 1, 20,000 across India, are over 100 years old, it is the need of the hour to deploy the best suited material – Stainless Steel, to reduce casualties up to a great extent. Moreover, stainless steel has twice the life cycle compared to carbon steel”, said, President- ISSDA, Mr KK Pahuja. Overall costing for the life cycle of stainless steel is significantly lower.  India has a large coast line and structures along the coastline cities are suffering due to corrosion, resulting not only in losses due to frequent maintenance and replacements but also disruption in daily public life. Stainless Steel in structural elements is critical in coastal areas like Mumbai which are prone to high corrosion. Today, stainless steel structurals such as angles, sections, nuts & bolts, anchors, reinforcement bars are easily available, suiting to applications requiring long life in corrosive environments.
