Grade: T1, T2, T3, T4, T5, T6 The substrate is formed by hot rolling and annealing after one-time cold rolling, usually with a thickness of 0.17-0.5mm, which is called Single Reduce, or SR for short.

Common tin plating: 5.6/2.8, 8.4/2.8, 8.4/5.6, 11.2/2.8, 11.2/5.6, 11.2/8.4, 15.1/5.6 Tinplate with a small amount of tinplate is generally used for containers that require less high corrosion resistance and containers that are painted; tinplate with a large amount of tinplate is generally used for cans that require high corrosion resistance, and containers that are not painted directly.

Brand: DR-8, DR-9, DR-9M, DR-10
The substrate is formed by hot rolling, annealing after primary cold rolling, and then primary cold rolling. Therefore, secondary cold rolling is named, usually with a thickness of 0.12-0.36mm, which is called Double Reduce in English, or DR for short. The thickness of the second cold rolling is thinner and the strength is higher, which can reduce the cost of making cans, and the overall use ratio is increasing. And the production process is more sophisticated and complex, the supply capacity is relatively small, belongs to the overseas market is more marketable varieties.

Common tin plating: 2.8/2.8, 5.6/5.6, 8.4/8.4,11.2/11.2 Tinplate with a small amount of tinplate is generally used for containers that require less high corrosion resistance and containers that are painted; tinplate with a large amount of tinplate is generally used for cans that require high corrosion resistance, and containers that are not painted directly.

The vast majority of food packaging with tinplate steel base. Less residual trace elements, with excellent corrosion resistance.

Chrome plate is also called Wuxi steel plate, abbreviated as TFS, which is a new type of canning material developed for the situation of low metal tin resources and high cost. Compared with tinplate, it has the advantages of low price and strong coating adhesion, but it is not as good as tinplate in corrosion resistance and appearance gloss, and it cannot be soldered at present. It can only be welded or bonded by lap resistance welding. At present, it is mostly used for processing crown bottle caps and weak acid food cans. In recent years, its use has gradually become widespread.

Electrolytic tinplate integrates the advantage of steel and tin. It brings excellent properties of form-ability and strength, paint-ability and printability, solderability and weldability, corrosion resistance and beautiful appearance. Tinplate also has nontoxic and good ductility properties. It is widely used in food, medicine, commodity, instrument and general packaging.
