Stainless Steel Coil Surface Finish

Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of stainless steel coils can have different types.

The surface finish of stainless steel coils may vary depending on the desired application and the manufacturing process used. Some common surface treatments for stainless steel coils include:

1. 2B surface treatment: This is the most common and basic surface treatment for stainless steel coils. This is a smooth, shiny finish achieved by cold rolling or annealing the steel, followed by pickling and passivation.

2. No. 4 Finish: This is a brushed or satin finish created by using an abrasive belt or brush to create a consistent, even surface texture.

3. BA finish: BA stands for "Bright Annealed" and is a highly reflective mirror finish. It is achieved by annealing the steel in a controlled atmosphere, followed by pickling and passivation.

4. Matte: This is a non-reflective matte finish achieved by sandblasting or etching techniques.

5. 8K Mirror Polish: This is a very high gloss mirror finish created by using progressively finer abrasives or polishing compounds to create a smooth reflective surface.

The choice of surface finish for stainless steel coils depends on factors such as the intended use, aesthetic preference, and the manufacturing process used to make the coil.

Process of Production

The production process of stainless steel coil is: raw material preparation - annealing and pickling - (intermediate grinding) - rolling - intermediate annealing - pickling - rolling - annealing - pickling - leveling (finished product grinding and polishing) - cutting, packaging and storage .

Packing and Transportation

the standard sea packaging of stainless steel coil

Standard export sea packaging:

Waterproof Paper Winding+PVC Film+Strap Banding+Wooden Pallet or Wooden Case;

Customized packaging as your request (Logo or other contents accepted to be printed on the packaging);

Other special packaging will be designed as customer’s request;

The standard packaging for stainless steel coils typically involves coiling the steel around a large spool or reel and securing it with metal strapping or bands. The coils are then placed on a wooden pallet and tightly secured with metal bands or straps to prevent movement during transportation. Depending on the supplier and the transportation method, the coils may be wrapped in a protective covering to prevent damage from weather elements or impacts. The exact packaging may vary depending on the size and shape of the coils, as well as any specific handling requirements for the steel. It is important to follow the supplier's instructions for handling and storing galvanized steel coils to ensure their quality and longevity.
