Storage Tanks Manufacturer Center Enamel: Bolted Tank Engineering from 20 m3 to 60,000 m3

Behind every durable bolted tank stands a manufacturer's entire system: the steel sourcing, the enameling chemistry, the coating line, the design office, and the export logistics. Few storage tank manufacturers worldwide own that full chain — and ownership of it is exactly what separates a 30-year tank from a decade of recoating and repair.

Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd), founded in 2008 with enameling roots back to 1989, is China's first Glass-Fused-to-Steel tank manufacturer and Asia's leading bolted tank producer, holding nearly 200 enameling patents. From a 100,000 m2 production base with 250,000 panels of annual capacity, the company delivers GFS, fusion bonded epoxy, stainless, and galvanized bolted tanks from 20 to 60,000 m3 to more than 100 countries.

1. Company Profile and Manufacturing Strength

Scale and vertical integration are the foundation of every specification Center Enamel meets.
