TMBP & SPCC

Cold Rolled Coil is produced, without heating, from pickled hot rolled coil which is rolled to 0.130mm~0.80mm (Ton Yi's product specification) through the process of electrolytic cleaning and annealing, and temper rolling. Due to its thin gauge, precise dimension, diversified surface roughness grades, easy to be coated and electroplated, excellent mechanical and processing properties, and easy to be punched and pressed, cold rolled steel can be used widely in such areas as electronic parts, appliances, steel furniture, containers, structural materials, etc.

Ton Yi's Cold Rolled Plant (TMBP plant) is a cold rolled plant with world-class technology and facilities. Except for supplying the customer with tin mill black plates (BP), cold rolled steel (SPCC) of thin gauge for electric and electronic parts and for galvanization is also the most competitive product in Ton Yi.
