In continuous units in cold rolled steel strip, galvanized steel (electro galvanized and hot dip galvanized) as substrate, after surface pretreatment (degreasing and science processing), using the method of roll coating, coated with a layer or multi-layer liquid coating of plate, after baking and cooling income is the coating steel plate. Because the coating can have a variety of colors, on the habits of the coated steel sheet is called color coating steel plate. Because the coating is carried out before the sheet metal forming, in foreign countries which is called pre coating plate.

Color coated steel sheet is an organic coating coating on the steel surface, it has the advantages of beautiful appearance, bright color, high strength, good corrosion resistance, easy processing molding, but also allows the user to reduce costs, reduce pollution.

From the United States in 1935 to establish the first continuously coated steel line to begin, color coated steel plate has been widely applied, the current color coated plate varieties, about more than 600 kinds, the advantages of color coated sheet and organic polymer and steel plate of the two, which has good colorability, organic polymer molding, corrosion resistance and decorative, and steel plate with high strength and easy processing, can easily be punching cutting, bending, deep drawing processing. Made this makes organic coated steel sheet products have excellent practical, decorative, workability, durability.

Q:Are steel sheets suitable for solar panel mounting?: Yes, steel sheets are suitable for solar panel mounting. Steel is a strong and durable material that can provide a sturdy base for solar panels. It is resistant to rust and corrosion, making it ideal for outdoor installations. Steel sheets can be easily fabricated into various shapes and sizes to accommodate different solar panel configurations. Additionally, steel is readily available and cost-effective, making it a popular choice for solar panel mounting systems. Overall, steel sheets offer the necessary strength, stability, and longevity required for supporting solar panels effectively.

Q:What are the common thicknesses of steel sheets?: The common thicknesses of steel sheets range from 0.4mm to 6mm, depending on the intended application and industry standards.

Q:What is the difference between a hot rolled and pickled steel sheet?: A hot rolled steel sheet is produced by heating the steel above its recrystallization temperature, typically around 1700°F (926°C), and then rolling the heated material into a desired shape or thickness. This process gives the steel a characteristic scale or oxide layer on its surface. On the other hand, a pickled steel sheet undergoes an additional step called pickling, which involves removing the scale or oxide layer that forms during the hot rolling process. Pickling is typically done by immersing the steel sheet in an acid bath, such as hydrochloric acid, to dissolve the scale. The main difference between a hot rolled and pickled steel sheet lies in the surface finish and cleanliness. A hot rolled steel sheet will have a rougher surface due to the presence of the scale, which can be visually unappealing and may require additional processing or finishing. In contrast, a pickled steel sheet will have a smoother and cleaner surface since the scale has been removed. Another difference is the corrosion resistance of the two types of steel sheets. The presence of the scale on hot rolled steel can make it more susceptible to corrosion, especially in humid or corrosive environments. Meanwhile, pickled steel has a better resistance to corrosion due to the removal of the scale and the subsequent application of a protective coating or treatment. In terms of applications, hot rolled steel sheets are commonly used in structural components, construction materials, and general fabrication where surface finish is not critical. Pickled steel sheets, on the other hand, are often preferred in industries such as automotive, appliances, and manufacturing, where a smooth and clean surface is desired for further processing or finishing. In summary, the difference between a hot rolled and pickled steel sheet lies in the surface finish, cleanliness, and corrosion resistance. While hot rolled steel has a rougher surface due to the presence of scale, pickled steel undergoes an acid bath to remove the scale, resulting in a smoother and cleaner surface. Pickled steel also offers better resistance to corrosion and is preferred in applications where a high-quality surface finish is required.

Q:What are the different methods of surface cleaning for steel sheets?: Surface cleaning of steel sheets offers various methods, each with its own advantages and applications. 1. Mechanical Cleaning: To physically eliminate dirt, rust, and other contaminants from steel sheet surfaces, one can utilize sandpaper, wire brushes, or abrasive blasting. This approach is ideal for heavy-duty cleaning and preparing surfaces for further treatment or coating. 2. Chemical Cleaning: By employing chemicals or detergents, one can dissolve or remove contaminants from the steel surface. This method is particularly effective in eliminating grease, oil, and other organic substances. It is crucial to select the appropriate chemical cleaner based on the type of contamination and the composition of the steel sheet, ensuring effective cleaning without surface damage. 3. Electrolytic Cleaning: This technique involves submerging the steel sheet in an electrolyte bath along with an electric current to dissolve and separate contaminants. Electrolytic cleaning is effective in removing stubborn rust, scale, and oxidation, while also providing a polished finish. 4. Power Washing: Also known as pressure washing, this method employs a high-pressure water stream to cleanse the steel surface. Power washing effectively removes loose debris, dirt, and mild contaminants. However, it may not be suitable for heavy-duty cleaning or the elimination of stubborn substances like rust. 5. Vapor Degreasing: Vapor degreasing utilizes solvent vapors to clean the steel surface. By exposing the steel sheet to these vapors, contaminants are dissolved and removed. This technique is particularly effective in eliminating oil, grease, and other organic substances. Vapor degreasing is a precise and controlled cleaning method commonly utilized in industrial applications. Before selecting a surface cleaning method, it is crucial to consider the type and severity of contamination, the desired level of cleaning, and the specific requirements of the steel sheets. Additionally, it is important to prioritize safety precautions and utilize appropriate protective equipment when performing any surface cleaning procedure.

Q:What kind of material does ordinary steel plate refer to in steel market?: When we use high temperature resistant, steel plate are sometimes exposed to outdoor or there is a very high temperature, but our common plate is very weak in high temperature resistance, this is mainly because the composition of carbon and iron is very weak. But the alloy steel plate has solved this problem, because other alloy elements join, our alloy steel plate in the metal element combination aspect has obtained the very good solution.
