We, Taixing Zhicheng Glass Co., Ltd, are a factory engaged in the field of 3.3 high boroslicate glass products. We have our own furnace to make production for those borosilicate glass tubes and can do deep processing to them, such as cutting straightly, firing, melting, polishing, end-closing, frosting, color-printing and etc.. We are the member of China International Trade Promotion Committee and International Chamber of Commerce. We also have the right to operate our own exports and imports.
Our main products are glass tubes and rods of 3.3 high borosilicate and all kinds of explosion-proof luminous light tubes; all sizes of candle holders and general or art lamps made of glass tubes; blowing and pressed products made of 3.3 high borosilicate glass; all-glass solar vacuum tubes and etc..
To promote much better our business philosophy, making good quality and service as fundamental and reaching glory with innovation and integrity, we arrange all the works in accordance with the requirements of ISO9001 Quality Management System Certification and we have already got this certification and also have been awarded as the “ Quality Trustworthy Firm” by Jiangsu government.
We are located in the provincial Hongqiao Industrial Park in Yangtze Delta. The transportation is very convenient here.
Excellent teams, sophisticated equipments, highly effective management and positive philosophy are the guarantees of our quality. Trying best to satisfy our customers and reaching the win-win effect are our eternal pursuit. We are sincere to establish long-term business relationships and develop together with all the customers in and abroad.
