Advantage
Graceful color,showing the splendor of your quality, wear-resistant as well, strong corrosion resistance , anti-rust property and decorative effect, durable and beautiful in good taste.

2, the classification according to production method (1) hot-rolled steel (2) cold-rolled steel
3, according to surface features.
Surface characteristics of manufacturing summary of uses
The NO.1 silver white
Matt hot-rolled to the required thickness and then by annealing and descaling a rough matt surface does not require the use of surface gloss
NO.2D silver white after cold rolling, heat treatment and pickling, sometimes in the rough surface roll the final a light rolling a matt surface processing 2D products for the purposes of strict requirements on surface, usually timber, deep timber
After NO.2B strong luster NO.2D NO.2D, processing, polished rollers ultimately a mild cold-rolled to obtain the appropriate luster. This is the most common surface processing, the processing can be used as the first step of polishing. General timber
BA bright as a mirror standard, but is usually bright annealed surface processing, the high surface reflectivity. Building materials, kitchen utensils
The NO.3 coarse grinding NO.2D and NO.2B material with 100 to 200 # (units) Tobe Abrasive band grinding building materials, kitchen utensils
The NO.4 middle grinding the NO.2D and NO.2B material, using 150 ~ 180 # Tobe Abrasive belt grinding and polishing the surface, which is common, with the light of the visible 'grain' specular reflection surface Ibid.
NO.240 of fine grinding the will NO.2D and NO.2B material, kitchen utensils # 240 whetstone grain grinding with grinding
The NO.320 fine grinding the will NO.2D and NO.2B material 320 # Tobe Abrasive belt grinding ibid.
The NO.400 luster closer to BA the NO.2B materials, with # 400 polishing wheel for grinding general timber, standing timber, kitchen utensils
HL Hairline grinding the appropriate particle size of the abrasive grain grinding (150 ~ 240 #) Tobe tablets many buildings, constructional material
The NO.7 close to the mirror abrasive # 600 rotary polishing wheel for grinding art, decorative
The NO.8 mirror grinding the mirror using a polishing wheel for grinding the mirror and decorative
