A steel plate is a flat, solid piece of steel with uniform thickness, widely used in construction, manufacturing, and industrial applications due to its strength and durability. Typically, steel plates are made from carbon steel, stainless steel, or alloy steel, allowing them to resist wear, impact, and corrosion. They come in a range of thicknesses, from thin sheets to heavy-duty plates, depending on their intended use. Steel plates are essential in building infrastructure like bridges, buildings, ship hulls, and machinery parts, making them a crucial material in various engineering and structural projects.

Steel plates come in various finishes, each tailored to specific applications and aesthetics. Hot-rolled finishes involve heating and rolling steel at high temperatures, creating a rough, matte surface ideal for structural uses. In contrast, cold-rolled finishes are created at room temperature, resulting in a smoother, shinier finish suitable for precision applications. Galvanized finishes coat steel with a layer of zinc for excellent corrosion resistance, making it suitable for outdoor and marine environments. For a decorative, textured look, brushed finishes use an abrasive to create a unique surface pattern. Powder-coated finishes apply a durable, scratch-resistant layer in various colors for a visually appealing, protective coat. Polished finishes create a high shine, often used in stainless steel for reflective surfaces, while pickled and oiled finishes remove impurities and add a protective oil coating to prevent rust, especially useful in applications needing further processing like welding or painting. These finishes help steel plates meet diverse industrial, structural, and decorative requirements.
