Welcome to website of Comat! We are one of the leading tinplate sheet manufacturers and suppliers in China. Our tinplate sheet has the advantages of strong corrosion resistance, high formability, easy welding, and certain strength and hardness. The tin coating is non-toxic, odorless, and glossy, and can beautify products with printed patterns. According to different manufacturing techniques, the tinplate sheet is divided into thermal and electrolytic tinplate, which are widely used as packaging materials in the canned food, chemical, paint, medicine and other industries. In the following, you can learn specific information of the tinplate sheet. We hope you can find the product that suits your needs.

Equal Tinplate Sheet
The equal tinplate sheet is cold-rolled electrolytic tinplate with uniform tin coating weight on both sides.

Differential Tinplate Sheet
The differential tinplate sheet refers to the cold-rolled electrolytic tinplate that has different tinning volume on its two sides.

GradeⅠTinplate Sheet
Under normal storage conditions, the gradeⅠelectrolytic tinplate sheet examined online is suitable for regular coating and printing of the whole steel plate surface, without the following defects.
1. Pinholes crossing through the steel plate.
2. Thickness deviation beyond allowed standards.
3. Surface blemishes like scars, pits, creases, and rust, etc.
4. Flaws in shape.

Grade Ⅱ Tinplate Sheet
The surface quality of grade Ⅱ tinplate sheet is inferior to that of gradeⅠtinplate. As small apparent surface and shape blemishes like the inclusion, crease, scratch, oil stain, dent, and burr, etc. are allowed, regular whole steel plate coating and printing can not be guaranteed by the grade Ⅱ tinplate sheet.
