5.Applications for Different Surface Finishes

No.1:
For heavy-duty industrial environments. Our No.1 finish offers excellent heat resistance and a uniform matte surface that hides wear and tear.
2B:
The workhorse of stainless steel. If you need a balance between cost, formability, and reflectivity, 2B is your go-to choice for deep drawing.
BA:
right Annealed for a decorative shimmer. Perfect for architectural panels where you want a mirror effect without the premium price of 6K.
No.4:
The hygienic standard. No.4 brushed finish hides fingerprints and scratches, making it mandatory for commercial kitchens and food processing lines."
6K:
True reflection. Our 6K finish undergoes multi-stage polishing to eliminate any pinholes or distortion. Ideal for high-end architectural accents.

6.Presentation of the process for packaging the non-perishable steel coils in containers

For the general stainless steel coils, we usually ask the customers to divide them into coils weighing between 4 and 7 tons each. This is to facilitate better loading into containers, as the net weight requirement for stainless steel coils in 20GP containers cannot exceed 28 tons.
