What is Stainless Steel ?
Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.
Surface Finish | Definition | Application | |
2B | Finished by heat treatment , picking or equipvalent cold rolling , followed by skin pass to obtain adequate luster surface. | With bright and smooth surface ,easy for further grinding to obtain brighter surface ,suitable for medical instruments ,milk containers ,tableware and so on. | |
BA | Bright heat treatment after cold rolling. | Structual members .etc.kitchen utensil ,cutlery ,eleltric applicances ,medical instruments ,building decorations ,etc. | |
NO.3/NO.4 | Polished with No.150-240 abrasives. | Milky food processing equipment , medicalinstruments ,building decorations. | |
HL | Finshed by polishing with abrasives of suitable grain size to obtain continuous streaks. | Building decorations ,such as elevators ,escalators ,door etc. | |
6K/8K | A mirror-like reflective surface ,which is obtained by polishing with successively finer abrasives and buffing extensively with all gritlines are removed. | Buliding entrances,bulkding column casting ,elevator's wall doors ,counters,sculptures etc. |

Company Profile
As a premier stainless steel surface designer in China, ASIA Metal Service Company Limited established in 2021, which strives for stainless steel innovation and quality for more than 10 years. So far, we have developed into a large integrated enterprise of stainless steel material’s design, processing.
Packing details
We will use the packingpaper against the customers need.And if the shipping is over 10days or have special climate we will use waterproof packing and add aplastic film to prevent from the water,moisture and rusting.
Packing in the container:we use the woodenpallet,triangularwood to fixthecoil,and the steel wireropetoholdonon the bothside.That can prevent from the crushin juryef fectively.
In addition,we can also provide special container according to customer needs.
