Product Overview

T2.5 Electrolytic Tinplate (ETP) belongs to single-reduced (SR) ultra-thin low carbon steel electroplated pure tin on both sides, complying with GB/T 2520 and ASTM A623 standards. T2.5 grade HR30T hardness 52-58, sits between T2 and T3 temper, offers higher rigidity than T2 while keeping good ductility. Available in coil and sheet form, tin coating weight 1.1~11.2 g/m². Surface finish choices: Bright, Stone, Silver, Matte. It is widely used for medium-rigid food cans, seafood containers, and general metal packaging requiring stable stamping. T2.5 ETP supports printing and internal anti-corrosion coating, ideal for mass can production. Mill test certificates can be provided for export orders.
