[Asia Economy Yeongnam Reporting Headquarters Reporter Yeo Jong-gu] Did you know that the steel materials for the world's longest suspension bridge are 'Made in POSCO'?

Turkey's '?anakkale Bridge' is currently the longest suspension bridge in the world, connecting southern Turkey. Using this recently opened bridge, a journey that used to take over an hour by ferry can now be completed in just 6 minutes.

During the construction of the ?anakkale Bridge, which is gaining attention as a transportation hub connecting Europe and Asia, 136,000 tons of POSCO steel were used.

The ?anakkale Bridge has a total length of 3,563 meters and tower heights of 334 meters. POSCO products are embedded throughout this suspension bridge.

POSCO supplied all the steel materials required during construction, from 39,000 tons of thick plates for the main towers, 53,000 tons of thick plates for the deck, to 44,000 tons of wire rods for the cables.

In conventional bridge projects, after the design company completes the design, discussions are held with the construction company, structure manufacturer, and steel suppliers.

However, the ?anakkale Bridge was built using a 'Design-Build' method, where the construction company was selected before the design phase, allowing the construction company and suppliers to collaborate from the design stage.

Based on extensive know-how, POSCO developed materials tailored to the customer's needs and even provided ideas for utilizing steel to enhance customer value. By presenting an integrated steel solution and securing the entire order, POSCO enjoyed significant success.

Active sales efforts targeting local construction companies are evaluated to have led to this major contract success.

POSCO closely managed wide-width steel production to minimize local processing costs and lead times, welding technology for thick plates over 100mm, and steel storage and inventory management services utilizing POSCO's automotive steel processing center in Turkey (POSCO-TNPC).

Lee Sang-il, Manager of POSCO's Steel Construction Marketing Office, said, "We are proud to supply POSCO products to the world's longest suspension bridge," adding, "It was a monumental Korea project, as a Korean construction company built it using domestically produced POSCO steel."

POSCO plans to continue collaborating with domestic and international partners to maintain its strong performance in the global market.
