Leading Russian steel maker Mechel announced the supply of about 22,000 tonnes of rails and other metal products for the construction of the Big Circle Line of the Moscow Metro. The supplied rolled metal products were manufactured at several enterprises of the Mechel Group. Most of the products (rails, fittings, sheets and beams) are produced at the mills of the Chelyabinsk Metallurgical Plant. More than 7 thousand tons of rails were used to lay 28 kilometres of track between the new BCL stations. Metrostroevtsy also supplied B500S fittings, hardware, mesh of the Beloretsk Metallurgical Plant and a strip of the Izhstal plant. Cold-deformed reinforcement В500С is used for the manufacture of tubing - elements of prefabricated fastening for tunnel finishing.Moscow is preparing for the simultaneous launch of 10 metro stations of the western, south-western and southern sections of the BCL: Terekhovo, Kuntsevskaya, Davydkovo, Aminevskaya, Michurinsky Prospect, Vernadsky Prospect, Novatorskaya, Vorontsovskaya "," Zyuzino "and" Kakhovskoy ". The Big Circle Line is the largest project in the entire history of metro construction in Moscow. It will stretch for 70 kilometres, connecting the districts of the city, the radial lines of the metro and the railway. In total, the BCL will have 31 stations. 19 of them will become interchanges to other subway lines, the Moscow Central Ring or commuter trains.After the opening of traffic in all sections, the Big Circle Line will become the longest metro ring in the world, 13 kilometres ahead of the current record holder, the second ring line of the Beijing Metro.
