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.

Packing details
1 Sheets covered with wooden plate for protection in transportation.
2. All sheets will be loaded in strong wooden packages.
3. Every cartons loaded with good shoring and strengthening.
4. Take container loading pictures and seal the container.
5. Transportation speed is quick. And keep customer each step informed.
What is 2B ?
2B Finished by heat treatment , picking or equipvalent cold rolling , followed by skin pass to obtain adequate luster surface.
What is BA ?
BA surface finished is Bright heat treatment after cold rolling.
What is NO.4 ?
No.4, also called #4, satin or directional finish, is an unidirectional finish obtained with a 100-400 grit abrasive depending on requirements. High grit numbers create finer polishing lines and more reflective finishes.
What is Hairline finished ?
Hairline referred to as "the HL",it’s grain as fine as hair, straight and continuous, delicate with oil paints on the surface. It has slightly lower reflective rate than satin stainless steel sheet.
What is Mirror finished ?
Mirror finish is produced by progressively using finer abrasives and finishing with extremely fine buffing compounds. Mirror finish is also called 8K, No.8 and polish finish, which is the most reflective mirror finish with high quality to similar as glass mirror. The final surface is blemish free with a high degree of image clarity and is the true mirror finish.
