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:What's the difference between steel plate 20 and Q235 steel plate?: Q235 steel yield point is 235MPa, the elongation is 21-26%; widely used in the production of general machinery parts have certain strength and elongation, such as pin, shaft, rod, connecting rod, ring, bolt, nut, cylinder, gear, rack, rack and welding parts.

Q:What is the typical coefficient of thermal expansion of a steel sheet?: The typical coefficient of thermal expansion of a steel sheet is around 10-12 parts per million per degree Celsius (ppm/°C). This means that for every degree Celsius increase in temperature, the steel sheet will expand by 10-12 ppm in all directions. However, it's important to note that the coefficient of thermal expansion can vary depending on the specific type and composition of the steel. Different types of steel alloys may have slightly different coefficients, but the range of 10-12 ppm/°C is a common average.

Q:Can steel sheets be used in architectural applications?: Yes, steel sheets can be used in architectural applications. Steel sheets are often used in architectural projects for their durability, strength, and versatility. They can be used in various applications such as roofing, cladding, facades, flooring, and structural elements. Steel sheets offer a wide range of design options and can be customized to meet specific architectural requirements. Additionally, their corrosion resistance and fire resistance properties make them suitable for long-lasting and safe architectural solutions.

Q:How are steel sheets protected against rusting?: Corrosion protection is employed to safeguard steel sheets against rusting. Several techniques are utilized for this purpose: 1. Galvanization: Zinc is applied as a coating on the steel sheets. Acting as a sacrificial anode, the zinc corrodes in lieu of the steel when exposed to moisture or oxygen. Consequently, a barrier is formed to shield the steel from rust. 2. Painting: A layer of paint is applied to the steel sheets, creating a protective barrier against moisture and oxygen. This physical barrier prevents contact between these elements and the steel, thus reducing the likelihood of rust formation. 3. Powder coating: Dry powder is spread onto the steel sheets and then heated to establish a protective layer. The powder liquefies and fuses into a smooth coating, offering remarkable resistance to rust and corrosion. 4. Electroplating: The steel sheets are immersed in a bath containing a metal coating solution, such as zinc or chromium. By passing an electric current through the bath, the metal coating bonds with the steel, serving as a safeguard against rust. 5. Phosphating: A chemical process deposits a layer of zinc or manganese phosphate onto the steel sheets. This layer enhances the adhesion of paint or other coatings, providing a surface resistant to corrosion. These techniques find widespread usage in various industries to avert the rusting of steel sheets. The selection of a specific method is contingent upon factors such as cost, durability requirements, and the intended environment for the steel sheets.

Q:Where can steel sheets be purchased?: Steel sheets can be purchased from a variety of places. Some common options include local hardware stores, home improvement centers, and metal supply companies. Many of these places offer a wide range of steel sheet sizes and thicknesses to choose from. Additionally, online retailers and e-commerce platforms also provide a convenient way to purchase steel sheets. These online options often offer a larger selection and competitive pricing. It is important to compare prices, quality, and customer reviews before making a purchase to ensure you are getting the best value for your money.

Q:How do steel sheets perform in terms of impact resistance?: Steel sheets are known for their exceptional impact resistance. Due to their high strength and rigidity, steel sheets are able to withstand significant impacts without deformation or failure, making them highly reliable and suitable for various applications where impact resistance is crucial.

Q:Can steel sheets be used for insulation cladding?: Typically, insulation cladding does not involve the use of steel sheets. Instead, materials like foam boards, mineral wool, or fiberglass are commonly chosen for their thermal insulation properties. These materials are effective in minimizing heat transfer and enhancing energy efficiency. Conversely, steel sheets are more frequently utilized for structural purposes or as a protective layer owing to their robustness and durability. Though steel sheets can offer some protection, they lack the requisite insulation properties required to effectively prevent the transfer of heat or cold. Consequently, it is advisable to employ suitable insulation materials specifically designed for cladding purposes.

Q:Can steel sheets be used in the construction industry?: Yes, steel sheets can be commonly used in the construction industry. Steel sheets are highly versatile and have a wide range of applications in construction. They are used for various purposes, including roofing, wall cladding, flooring, and structural components such as beams, columns, and trusses. Steel sheets are preferred due to their high strength-to-weight ratio, durability, and resistance to corrosion. They can withstand heavy loads and provide stability and structural integrity to buildings. Additionally, steel sheets can be easily fabricated, allowing for customization and efficient construction processes. Overall, steel sheets are a popular choice in the construction industry due to their numerous advantages and suitability for various construction applications.

Q:How do steel sheets perform under heavy loads or pressure?: Steel sheets are renowned for their extraordinary strength and durability, rendering them highly impervious to immense loads or pressure. With their unique composition and manufacturing process, steel sheets possess an elevated tensile strength that empowers them to endure significant amounts of force without distorting or fracturing. This trait renders steel sheets exceptionally well-suited for applications involving substantial loads or pressure, such as construction, transportation, and industrial machinery. Moreover, steel sheets exhibit an exceptional load-bearing capacity, enabling them to evenly distribute applied pressure across their surface, thereby minimizing the likelihood of structural failure or damage. The rigidity of steel sheets further enhances their ability to withstand heavy loads or pressure, preventing them from bending or buckling and ensuring the integrity of the supported structure or equipment. In summary, steel sheets offer a dependable and robust solution for handling heavy loads or pressure, making them a favored material across various industries.

Q:What are the dimensions of steel sheets?: The dimensions of steel sheets can vary depending on the specific requirements and applications. However, commonly available steel sheets come in standard sizes such as 4 feet by 8 feet or 5 feet by 10 feet. Additionally, steel sheets can be found in various thicknesses ranging from thin gauges (e.g., 28 gauge) to thicker options (e.g., 16 gauge).
