| Thickness | 0.1mm - 50mm |
| Finish | There are several types of steel sheets and plates available in the market, each with its unique characteristics. Hot rolled plate (HR) is one such type that undergoes a heating treatment process, followed by rapid cooling to produce a sheet with a rugged surface. In contrast, Cold rolled sheet (CR) is made by subjecting the steel plate to a series of roller compressions that cause a reduction in thickness. This method produces a smoother surface finish. Another commonly used sheet type is the 2B sheet, which is characterized by a dull, matte appearance, owing to the use of a special rolling process. The 2D sheet is similar in appearance to the 2B sheet but has a slightly smoother surface finish. A more polished look can be achieved with the BA NO(8) sheet, which has a mirror-like finish. Finally, the SATIN sheet is a met with plastic coated sheet that has a unique texture, resulting from the application of a thin layer of plastic coating onto the surface of the sheet. The coating also makes it more resistant to abrasion and corrosion. Overall, the choice of sheet type depends on its intended use and the desired appearance and mechanical properties. So, it is essential to consider the properties of each type before making a decision. |

They are available in different thicknesses and can be cut or formed into various shapes. Shim sheets, on the other hand, are thin sheets used for precise alignment and spacing in machinery or structural components. Perforated sheets have holes or perforations of various sizes and shapes, offering ventilation, filtering, or decorative purposes. Chequered plates are distinctive due to their patterned surface, which provides enhanced grip and durability. These plates are commonly used in industrial flooring, stairs, and other applications requiring slip resistance. Finally, flats refer to flat bars of metal typically used in construction, manufacturing, and general fabrication. By understanding the unique features and applications of these different forms of sheet metal, individuals can choose the most suitable option based on their specific project requirements. |
