Bangladesh's float glass manufacturing industry is growing at 20-25% annually, benefited by its duopoly market structure. The 150BN/Tk float glass market is shared by Nasir Glass and PHP Float Glass to the extent of 65% and 15% respectively, leaving the rest of demand to two other local sheet glass makers and importers. The country's oldest glass manufacturer, state-owned Usmania Glass Factory and MEB Sheet Glass Industries are producing sheet glass but have very minimum market share. The two market leaders, Nasir and PHP are now planning to extend their markets further as local demand is rising daily. Nasir Group has plans to set up a second manufacturing unit investing nearly 120BN/Tk while PHP Float Glass has also planned to double production capacity from 2500 to 5000 tonnes monthly, investing more than 150BN,Tk.
