The company is mainly engaged in float glass, automotive glass and glass deep processing business. The original float glass production capacity is 630,000 tons/year, 15 million square meters of deep processing glass per year, and 800,000 sets of automotive glass per year. The company currently has 4 production lines in Shanghai, Guangdong and Tianjin, of which three lines in Shanghai and Tianjin can produce automotive-grade glass. The depreciation of the two lines in Shanghai has basically been completed, and the two lines in Shanghai and Tianjin will generally be cold repaired in 2009. Although the company has adopted heavy oil substitution to reduce costs, it is still under high cost pressure. Affected by rising costs and falling prices, the company's gross margin level has gradually declined in recent years. After the gross sales margin fell to 11.58% in the fourth quarter of 2005, the gross margin level for the 2006 quarter showed an upward trend. The recovery of the domestic glass industry and the adjustment of the company's business structure will help the company further enhance its profitability. The current production line layout does not meet the needs of the company's development strategy. In order to adapt to industrial development and achieve economies of scale, on the one hand, the company is speeding up production capacity construction and mergers and acquisitions. At the same time, it is also actively adjusting the product structure to increase the share of high-end product business, and is exploring investment in fields such as photovoltaic cells, solar energy, and TFT to cultivate new profit growth points. Currently, the Changshu 500T/D production line is about to be put into operation, and the acquisition project is under negotiation. The company's net profit level in 2006 and 2007 is expected to increase by about 10% compared to 2005, so the current stock price is slightly overvalued. The company's investment highlight, however, is the extent to which new businesses are being promoted in the future. In the process of the overall recovery of the glass industry and the gradual implementation of the company's development strategy, it is recommended to pay more attention to the company.
