Steel Enameling StepsUIG employs the latest breakthrough technology in steel enameling industry based on the utilization of Titanium (Ti) rich Hot Rolled Carbon Steel specifically prepared for enameling application only. During enameling (Ti) rich Hot Rolled Carbon Steel has excellent chemical properties and physical performance due to its high titanium content which eliminates Fish Scale defect. Furthermore superfine glass foam-like structure of the enameled layer provides enameled steel plates with excellent flexibility and durability.
