Original face: No. 1 the surface of heat treatment and pickling treatment after hot rolling. Generally used in cold-rolled materials, industrial tanks, chemical industry, such as equipment, thicker than 2.0mm. 0MM.
Blunt surface: No. 2D cold rolled after heat treatment, pickling, the material is soft, the surface is silver-white luster for deep stamping processing, such as automotive components, water pipes.
Fog surface: No. 2B cold-rolled after heat treatment, pickling, and then finishing to make the surface for a moderate light. Because the surface is smooth, easy to grind again, make the surface more bright, use a wide range, such as tableware, building materials and so on. After surface treatment with improved mechanical properties, almost all uses are satisfied.
Coarse sand No. 3 the product which grinds out with 100-120 #. With a better gloss, with discontinuous coarse lines. Used in building interior and exterior decorative materials, electrical products and kitchen equipment.
Fine sand: No. 4 with grain size No. 150-180 abrasive strip grinding products. Has a better gloss, with discontinuous coarse lines, stripes than No. 3 fine. It is used for baths, interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.
Sao 320 with No. 320 # abrasive strips. Has a better gloss, with discontinuous coarse lines, stripes than No. 4 fine. It is used for baths, interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.
Filament surface Hairline: Hlno. 4 The products of grinding pattern are produced by continuous grinding of abrasive belt with appropriate granularity (subdivision 150-320). Mainly used for building decoration, elevators, building doors, panels and so on.
Bright surface: Ba after cold rolling to light annealing, and after the formation of products. The surface gloss is very good, has the high reflectivity. Like the surface of a mirror. For household appliances, mirrors, kitchen equipment, decorative materials.
