1). The size of tin metal sheet. The commonly used thicknesses are: 0.17,0.18,0.20mm, 0.23mm, 0.25mm, 0.28mm; the commonly used widths are: 775mm, 800mm, 875mm, 900mm, 950mm, 1000mm, 1025mm; the length can be selected within the allowable range to meet the requirements This kind of tank type requires the most economical materials. In addition, in order to reduce scraps, manufacturers will also provide a variety of bottom and cover corrugated tin metal sheet.
2), The amount of tin plating on tinplate sheet. The amount of tin plating is a measure of the thickness of the tin layer, expressed in terms of the amount of tin plating per unit area (g/m2). Generally, the larger the amount of tin plating, the thicker the tin layer and the better the corrosion resistance. Generally, the actual thickness is 0.4~ 1.5μm. The standard of tinplate sheet in our country can refer to GB2520-88 standard.
3). Metal sheet coating surface finishing. Surface finishing is distinguished by the structural texture of the steel substrate and whether the coating has undergone reflow. metal sheet coating can be made into four different effects: bright surface, stone surface, silver surface, and matt surface. Among them, the most widely used are bright surface and stone surface.
