The first large-scale maintenance of a duplex system normally takes place after about 25 years.
Had the steel used to build the Eiffel Tower been galvanized before painting, only 7 maintenance operations would have been required since 1889, compared to the 18 that have taken place. If Eiffel Tower had been hot-dip galvanized and then painted, which is known as a duplex system, any damage to the paint coating will not lead to corrosion as the steel would continue to be protected by the Zinc, which underlies the paint. 130 Crore.Īmazed at the cost and complexity of the work involved in repainting the tower, where the painters must use hooks, ropes, safety nets and cannot begin painting each day until the morning dew has evaporated a Dutch corrosion expert recently made a hypothetical calculation of cost savings had the Eiffel Tower been built on galvanized steel. Painting the entire Tower takes 15 months to complete and a mammoth 60,000 kilograms of paint is used for the first coat that cost around $20 million each time – Rs. From the date Eiffel Tower was built, in 1889, the tower has been painted 18 times, once every 7 years. The Eiffel Tower is built of riveted wrought-iron, a material that only lasts if it is painted periodically. Subsidiaries-Audited Financial Statementsġ5 months rigorous job by 25 painters – 60,000 KGs of Paint – 1500 brushes – 5000 sanding disks – 1500 set of work clothes and USD 20 million each time – this is what it takes to keep the world’s most sought after Tower standing.Disclosures under Regulation 46 and 62 of the SEBI (LODR).Case Studies – Health & Safety Management.
