Brief Introduction

1. Prepainted Galvanized Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

2. The base metal for Prepainted Galvanized Steel Coil is HDGI Steel. The finish coats of Prepainted Galvanized Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

4. The color of the Prepainted Galvanized Steel Coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.

5. The Prepainted Galvanized Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

Edit

Because there is no after annealing treatment, the hardness is very high (HRB greater than 90), mechanical processing performance is poor, only a simplebending process has less than 90 degree directional (direction perpendicular to the rolled).

Edit

Hot rolled products with high strength and good toughness, easy processing and good forming can be excellent performance of welding, which is widely used in ships, cars, bridges, buildings, machinery, boiler, pressure vesselmanufacturing industry.

The scope of application:

(1) after annealing processing into the common cold;

(2) processing galvanized galvanized unit before the annealing treatment;

(3) the basic do not need to process the panel.

4 four, classification

Carbon steel plate, carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, container plate etc.. Rolling hard volumes: under normal temperature,the hot pickling volumes of continuous rolling.

Hot rolled steel strip products include steel (roll) and the shear of steel plate.And steel (coils) can be divided into straight and finishes volume (the volume,smooth rolling and slitting roll).

Q: 1.5mm galvanized steel prices?: Steel plate is made of molten steel, cooled and compressed into flat steel. The steel plate is flat, rectangular, and can be rolled directly or cut from a wide strip of steel. Steel plate by thickness, thin steel plate <4 mm (thinnest 0.2 mm), thick steel plate 4~60 mm, extra thick steel plate 60~115 mm. The steel plate is divided into hot-rolled and cold-rolled parts according to rolling. The width of the sheet is 500~1500 mm; the thickness is 600~3000 mm. According to the type of steel sheet, ordinary steel, stainless steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet; according to professional use, with drums board, enamel board, bulletproof plate; surface coating and plating, plating with zinc thin plate, tin plate, plating lead sheet, plastic composite plate.

Q: What is the tensile strength of steel sheets?: The tensile strength of steel sheets typically ranges from 370 to 690 megapascals (MPa), depending on the grade and thickness of the steel.

Q: How do steel sheets perform in thermal conductivity?: Steel sheets have high thermal conductivity, meaning they are efficient at transferring heat. This property makes them ideal for applications that require heat transfer, such as in heating systems, cookware, and industrial processes.

Q: What are the different sheet metal forming techniques for steel sheets?: There are several different sheet metal forming techniques that can be used for steel sheets. These techniques are utilized to shape the metal into desired forms and structures. Some of the common sheet metal forming techniques for steel sheets include: 1. Bending: This is a widely used technique in which the sheet is bent to create angles, curves, or complex shapes. It can be done manually or by using machines such as press brakes. 2. Stretch forming: In this technique, the sheet is stretched and formed over a mold or die to create a desired shape. It is commonly used for large and curved components. 3. Deep drawing: This technique involves using a punch and a die to form a sheet metal into a desired shape. It is commonly used for creating cylindrical or box-like structures such as cans, pots, or automotive components. 4. Roll forming: Roll forming involves passing the sheet metal through a series of rollers to gradually shape it into a desired form. It is often used for producing long and continuous shapes such as rails, tubes, or channels. 5. Spinning: This technique involves rotating a sheet metal while shaping it against a mandrel using a spinning tool. It is commonly used for creating cylindrical or conical shapes such as lampshades or cookware. 6. Embossing: In this technique, the sheet metal is stamped with a pattern or design to create a raised or recessed surface. It is commonly used for decorative purposes or to improve the structural integrity of the sheet. 7. Hydroforming: Hydroforming utilizes hydraulic pressure to shape the sheet metal into complex forms. It is often used for creating automotive components such as car body panels or exhaust systems. These are just a few examples of the sheet metal forming techniques that can be used for steel sheets. The choice of technique depends on the desired shape, complexity, and requirements of the application.

Q: How do steel sheets compare to plastic sheets?: Steel sheets are generally stronger, more durable, and have a higher heat resistance compared to plastic sheets. They are better suited for heavy-duty applications, such as construction and industrial uses, where strength and durability are crucial. Plastic sheets, on the other hand, are lightweight, flexible, and cost-effective. They are commonly used for applications where weight and cost are important factors, such as packaging, signage, and some consumer goods. Ultimately, the choice between steel and plastic sheets depends on the specific requirements and intended use of the sheets.

Q: What is the process of etching or engraving on steel sheets?: The process of etching or engraving on steel sheets involves using various techniques to create designs or patterns on the surface of the steel. Typically, a design is either etched or engraved onto a protective coating applied on the steel sheet using chemicals, tools, or lasers. The protective coating is then removed, revealing the etched or engraved design on the steel surface. This process is commonly used in industries such as manufacturing, jewelry making, and metal art.

Q: Are the steel sheets magnetic?: Yes, steel sheets are magnetic. Steel is primarily composed of iron, which is a ferromagnetic material. This means that it can be magnetized and attracts other magnetic materials. Steel sheets are often used in applications where magnetic properties are required, such as in the manufacturing of magnets, electrical appliances, and various industrial equipment.

Q: What is the process of applying weather-resistant coatings to steel sheets?: The process of applying weather-resistant coatings to steel sheets typically involves several steps. First, the steel sheets are cleaned and prepared to ensure proper adhesion of the coating. This may include removing any rust, grease, or other contaminants from the surface. Next, a primer is applied to the steel sheets to enhance adhesion and corrosion resistance. Once the primer has dried, the weather-resistant coating is applied using a variety of methods such as spraying, rolling, or brushing. The coating is then allowed to cure or dry according to the manufacturer's instructions. This process helps protect the steel sheets from the damaging effects of weather elements, such as moisture, UV radiation, and corrosion, prolonging their lifespan.

Q: Can the steel sheets be used for industrial machinery?: Yes, steel sheets can be used for industrial machinery as they are strong, durable, and have excellent load-bearing capabilities, making them suitable for various applications in the industrial sector.

Q: Can steel sheets be used for storage racks?: Indeed, storage racks can indeed be made using steel sheets. Renowned for their robustness and strength, steel sheets are an optimal choice when it comes to constructing storage racks. They possess the ability to bear substantial weights and offer steadfastness to the entire storage system. Furthermore, steel sheets can be effortlessly fabricated and tailored to suit the precise specifications of the storage area. Moreover, steel exhibits resistance against corrosion, guaranteeing the durability of the storage racks and rendering them suitable for employment indoors as well as outdoors.
