| Surface | There are various types of finishes available for stainless steel sheets, including 2B, 2D, BA, NO.1, NO.4, NO.8, 8K, mirror, checkered, embossed, hairline, sand blast, Brush, etching, and many more. These finishes are designed to provide different types of texture and appearance to the surface of the steel sheets. Some are smooth and glossy, while others are rough and textured. Each finish has its own unique characteristics and is chosen based on the specific application and desired aesthetic. Stainless steel sheets with these finishes are widely used in a range of industries, such as construction, automotive, food processing, and more. |
| Finish | HR, CR, 2B, 2D, BA NO(8), SATIN (Met with Plastic Coated) are different types of rolled plates and sheets. Hot rolled plates (HR) are manufactured by rolling heated slabs through a series of mills. This process makes them more malleable and easier to shape. HR plates have a rough surface due to the scale and oxide layers formed during the rolling process. On the other hand, cold rolled sheets (CR) are made by rolling metal at room temperature. This process results in sheets with a smoother and more precise finish. CR sheets have a matte surface and are commonly used in applications where aesthetics matter. The terms 2B and 2D refer to the surface finishes of stainless steel sheets. 2B finish is smooth, reflective, and has a uniform appearance, making it suitable for decorative applications. 2D finish has a dull, non-reflective surface and is often used in industrial settings. BA NO(8) stands for "Bright Annealed Number 8" and is a highly reflective surface finish. It has a mirror-like appearance and is commonly used in applications where a polished finish is desired. SATIN finish is achieved by coating the sheet with a layer of plastic. This coating provides protection and enhances the appearance of the sheet. SATIN finish is commonly used in applications where durability and aesthetic appeal are important. In summary, these different types of rolled plates and sheets offer various surface finishes and properties that cater to different applications and requirements. |
| Form | Foil, coil, roll, plain sheet, shim sheet, perforated sheet, chequered plate, strip, flat, blank (circle), flange rings, etc. These are just some of the various types of metal products available.
