Applications: Typically used for cold-rolled materials, industrial tanks, and chemical industrial equipment. It has a thickness range of 2.0MM-8.0MM.
Blunt Surface: NO.2D
Description: After cold rolling, heat treatment, and pickling, the material becomes soft and silvery white.
Applications: Suitable for deep stamping, such as in automotive components and water pipes.
Matte Surface: NO.2B
Description: Achieved through cold rolling, heat treatment, pickling, and then fine rolling, resulting in a moderately bright surface. The smooth surface is easy to re-grind for additional brightness.
Applications: Widely used for tableware, building materials, etc. It can meet almost all uses after surface treatment to improve mechanical properties.
Coarse Sand: NO.3
Description: Ground with 100-120 grit belts, offering better gloss with discontinuous coarse grains.
Applications: Used in building interior and exterior decoration materials, electrical products, and kitchen equipment.
Fine Sand: NO.4
Description: Ground with 150-180 grit belts, providing better gloss and finer stripes than NO.3.
Applications: Suitable for baths, building interior and exterior decoration materials, electrical products, kitchen equipment, and food equipment.
#320
Description: Ground with a 320-grit belt, offering better gloss and finer stripes than NO.4.
Applications: Used in baths, building interior and exterior decoration materials, electrical products, kitchen equipment, and food equipment.
Hairline: HL
Description: Features continuous grinding patterns generated by polishing belts with appropriate grit (ranging from 150-320).
Applications: Mainly used for building decoration, elevators, and door panels.
Bright Surface: BA
Description: Obtained by cold rolling, bright annealing, and flattening, resulting in an excellent gloss with high reflectivity, similar to a mirror.
Applications: Ideal for home appliances, mirrors, kitchen equipment, and decorative materials.
