The fusion between the steel sheet and the glass coating is a critical step in the production of Glass-Fused-to-Steel tanks, as it directly impacts the durability and service life of the tanks. At Shijiazhuang Zhengzhong Technology Co., Ltd(Center Enamel), we implement strict quality control measures throughout the entire production process — from raw material selection to the final product.
Before beginning mass production, we conduct thorough testing of raw materials to evaluate the quality of both the materials and the fusion between the glass coating and the steel panels. Only after these tests meet our high standards does full-scale production proceed.
The tanks are manufactured using an automated production line to ensure consistent and reliable quality. Upon completion, every steel panel undergoes a 1500V spark holiday test to verify coating integrity — ensuring 100% continuity with zero defects.
