Aluminium-conductor steel-reinforced cable coating thickness would be designated GC2. Higher strength grades of steel are designated high-strength (3), extra-high-strength (4), and ultra-high-strength (5). An ultra-high-strength galvanized steel core with class A coating thickness would be designated GA5. The use of higher strength steel cores increases the tensile strength of the conductor allowing for higher tensions which results in lower sag. Zinc-5% aluminium mischmetal coatings are designated with an "M". These coatings provide increased corrosion protection and heat resistance compared to zinc alone. Regular strength Class "A" mischmetal thickness weight coated regular strength steel would be designated MA2. Aluminium-clad steel is designated as "AW".
JSW Ispat Steel the Arabian Sea. This port can handle barges and mini-bulk carriers up to 4000 Dead Weight Tonnage (DWT). Moreover, a jetty adjoining the complex is capable of handling cargo of up to 10 million tonnes per annum. 2. Integrated Steel Plant at Kalmeshwar, Maharashtra The integrated steel plant at Kalmeshwar uses the latest steel manufacturing technology to produce galvanised sheets and products, apart from cold rolled coils. The Kalmeshwar complex houses a total of three advanced plants – a 0.325 million tonnes Galvanized Plain/Galvanized Corrugated plant, a 0.33 million tonne Cold Rolled Coils plant and a 60,000 tonne Colour Coated
