Glass fiber industry

Glass and glass product manufacturing accounts for approximately 15% of the shipment value of the ceramics and stone manufacturing industries, and is broadly divided into three industries based on product type: plate glass industry, glass product industry, and glass fiber industry.
[Plate glass industry]
It is a typical process industry that operates continuously day and night using large melting furnaces, and for this reason there are few companies in Europe and the United States. In Japan, the industry is dominated by three companies, Asahi Glass, Nippon Sheet Glass, and Central Glass (established in 1959), in order of sales share.
