1, carbon steel rimmed steel sheet (GB3274-88)
Steel rimmed steel sheet as the name suggests is made by boiling hot rolled steel plate made of ordinary carbon structural steel. Rimming steel deoxygenation is a complete steel, steel liquid oxygen content is higher, when molten steel after the injection mould, carbon oxygen reaction to produce large amounts of gas, resulting in liquid steel was named after boiling state. Rimming steel with low carbon content, and because no FeSi deoxidization, so steel containing silicon amount <0.07%. Boiling steel outer layer is crystallized in the boiling state, so the surface clean, compact, good surface quality, good processing performance. Rimming steel no large shrinkage hole, deoxidizer used less, low cost of steel. Rimming steel heart of impurities, with the serious segregation, mechanical heterogeneity, more gas in steel, low toughness, cold brittleness and aging sensitivity is larger, the welding performance is poor, so it does not apply to manufacturing under impact load, welding pieces of the structure and other important components work under low temperature.

Mill Finish: The most basic type of finish, the steel sheet remains as it is from the mill. It has a dull, gray appearance and is typically used for applications where aesthetics are not a priority. 2. Brushed Finish: Also known as a satin finish, this type of finish is achieved by brushing the steel sheet with a fine abrasive material. It results in a smooth, linear texture, giving the surface a contemporary and elegant look. 3. Polished Finish: Achieved by polishing the steel sheet with abrasive materials, this finish creates a smooth and reflective surface. It offers a high-gloss, mirror-like appearance, making it suitable for applications that require a sophisticated and luxurious look. 4. Embossed Finish: This finish involves pressing the steel sheet with embossing tools to create textured patterns or designs on the surface. It provides a unique and decorative appearance, ideal for architectural applications that require visual interest. 5. Patterned Finish: This finish entails applying patterns or textures onto the steel sheet using techniques like etching, laser cutting, or perforating. It creates visually appealing surfaces with intricate designs, suitable for both functional and decorative purposes. 6. Powder Coated Finish: This finish involves electrostatically applying a layer of dry powder paint to the steel sheet, which is then cured under heat. It offers a durable and vibrant finish, available in a wide range of colors and textures. This finish is highly resistant to chipping, scratching, and fading, making it ideal for exterior architectural applications. 7. Galvanized Finish: This finish is achieved by applying a layer of zinc coating onto the steel sheet through galvanization. It provides excellent corrosion resistance, making it suitable for outdoor architectural applications exposed to harsh environments. In conclusion, the choice of steel sheet finish depends on the desired aesthetics, durability, and environmental conditions of the architectural application.
