◉ Surfcae selection

SURFACE	CHARACTERISTIC	SUMMARY OF MANUFACTURING METHOD	APPLICATION
NO.1	Silvery white	Hot rolled to specified thickness	Do not need to have a glossy surface use
NO.1	lackluster	Hot rolled to specified thickness	Do not need to have a glossy surface use
NO.2D	Silvery white	After cold rolling, heat treatment and pickling are carried out	General material, deep material
NO.2B	Gloss is stronger than No.2D	After No.2D treatment, the final light cold rolling is carried out through the polishing roller	The general material
BA	As bright as a sixpence	No standard, but usually a bright annealed surface with high reflectivity.	Building materials, kitchen utensils
NO.3	Rough lapping	Grind with 100~200# (unit) strop tape	Building materials, kitchen utensils
NO.4	Intermediate grinding	Polished surface obtained by grinding with 150~180# strop abrasive tape	Building materials, kitchen utensils
NO.240	Fine lapping	Grinding with 240# strop abrasive tape	kitchenware
NO.320	Very fine grinding	Grinding was carried out with 320# strop abrasive tape	kitchenware
NO.400	The luster is close to BA	Use 400# polishing wheel to grind	General timber, building timber, kitchen appliances
HL	Hairline grinding	Suitable particle material for hair stripe grinding (150~240#) with many grains	Building, construction material
NO.7	It's close to mirror grinding	Use a 600# rotary polishing wheel to grind	For art or decoration
NO.8	Mirror ultrafinish	The mirror is ground with a polishing wheel	Reflector, for decoration
