Note: Tinplate is used in a wide range of applications. The above table is for reference only.


2.the annealing method

(1) Annealing methods include continuous annealing and box annealing.
  When continuous annealing is specified, the code name "CA" is added after the tempering specification code, such as T4CA;
  When box annealing is specified, the code name "BA" will be added after the specification code specification, such as T1BA.
(2) Soft materials (T1, T2, T2.5, T3 can now provide ultra-low carbon continuous annealing steel (IF steel), the material has excellent comprehensive performance, almost completely replace the original BA material.

3.Tin Coation Weight


Type Nominal coating weight (g/㎡) Minimum average coating weight (g/㎡) Code of coating weight
Equal Coating 1.1/ 1.1 0.90/0.90 10/10
2.8/2.8 2.45/2.45 25/25
5.6/5.6 5.05/5.05 50/50
8.4/8.4 7.55/7.55 75/75
11.2/11.2 10.1/10.1 100/100
Poor tin plating 1.1/2.8 0.90/2.45 10/25
2.8/5.6 2.45/5.05 25/50
2.8/8.4 2.45/7.55 25/75
2.8/11.2 2.45/10.1 25/100
5.6/8.4 5.05/7.55 50/75
5.6/11.2 5.05/10.1 50/100
8.4/11.2 7.55/10.1 75/100



(1) The coating weight is determined according to the end use of the product. Tinplate with heavy coating is used for cans with high corrosion resistance or cans without printing. Tinplate with light coating is used for cans with low corrosion resistance requirements or cans with printing.

(2) Differential Marking for the tinplate, in order to clarify the difference in coating weight, a white thin marking line is drawn on the edge of the strip, which we call “D-Mark”. In general, if the customer does not have special requirements, the marking line must be attached to the side of the light tin coated surface.
Such as:11.2/2.8D 2.8/1.1D

(3) Other forms of differential markings At the request of the customer, some are marking the pattern of a particular pattern on the entire surface. This type of marking is called "A-mark". Its marking line can be attached to heavy tin coated  surface or light tin coated surface.
Such as: 11.2A/5.6 2.8A/11.2 Differential coated products must use the marking (“D” or “A”), the request for cancellation of the mark is not acceptable.


4.Surface Finish


Surface Finish Sign Aiming Ra (μm) Features and Applications
Bright Extra BE 0.10-0.20  The brightest surface.
Bright B 0.20-0.35  Bright surface. generally used.
Stone R1 0.35-0.50  Stone surface. The defects caused by printing and can making are not conspicuous.
Super Stone R2 0.50-0.70  Rough stone surface.
Matte M 0.70-1.20  Dull finsh. For crown or DI cans (the tinplate is not reflowed).
Silver S1 0.70-1.20  Dull finish,for DI can or art can.
Satin SA 1.80-3.00  Rougher than dull finish,for art can.



5.Steel Type


TMBP only lists representative steel type
Steel type MR  It has few residual elements and has excellent corrosion resistance, and is widely used in general applications.
L  Cu, Ni, Cr, Mo and other residual elements are extremely rare, and are used as excellent corrosion-resistant cans.
D  Used for deep drawing or non-aging applications.



6.Chemical treatment (passivation)


Chemical treatment Process Applications
#311 Processing  Cathodic electrochemical passivation treatment of sodium dichromate  Mainly used for printing purposes, the most widely used.
#300 Processing  Sodium dichromate impregnation passivation treatment  A representative example is tinplate for DI cans, although it is also used in other  foods can without printing (eg, mushrooms, etc.) but rarely.
#71 Processing  Chromic acid cathode electrochemical passivation treatment  It has excellent coating adhesion and is mainly used for printing applications.



7.Oil type and Oil weight


Oil type Oil weight
DOS (DI-Octyl-Sebacate)   According to the application, the target center value can be 2 mg/㎡, 3 mg/㎡, 6 mg/㎡, or it can be increased or decreased according to the actual situation of the user.
