A colored or painted galvanized sheet is a metal sheet coated with electrostatic paint. Color sheets are available in about 15 different colors and vary in thickness from 0.18 mm to 0.7 mm. Color galvanized sheet is widely used and is the most widely used for covering roofs, attics, villas and sheds. The galvanized coils produced by the galvanized sheet production department go into the sheet preparation section. In this section, the surface of the plate is polished; this removes grease or impurities from the metal surface. After this step, the well-degreased plate surface is brushed with a special roller. Use a brush to make the surface smooth and even, and the painting process will be done on a high-quality galvanized sheet. The surface of the sheet was then washed with water and dried by aeration. Finally, to improve the plate's corrosion resistance and increase the paint's adhesion to the plate's surface, the surface is sprayed with chemicals and dried at an appropriate temperature. The prepared sheet then goes to the dyeing stage. When painting, you must first apply a base color to the top and bottom surfaces of the plate before going it into the oven. After the plate has cooled, the final color of various materials such as polyester, epoxy, polyvinyl chloride, or polyurethane is applied to the surface with rollers and the color curing stage enters again. The finished product has high corrosion resistance and excellent formability. Coloring pages are available in different shapes, such as louver or hatched, pottery design, crescent or sine, and gable; In addition, these sheets are available in a variety of colors including red, blue, white, brown, burnt brown, green, silver, purple, pink, yellow, liver, cream, and other colors. In general, it must be said that many manufacturing industries are supported by these plates. The color coating thickness is 20 to 25 microns on top of the color sheet and about 7 to 15 microns on the back. Plates are produced in thicknesses of 0.20 to 0.70 mm. These sheets are available in the market in as many as 15 colors. 
Application for coloring
- Construction (types of roofs - warehouses, workshops and sheds - external and internal facades of buildings)
- Manufacture of household appliances (refrigerator and freezer - water heater - gas stove - washing machine - microwave oven, etc.)
- The metal industry (cabinet-office equipment-partition type-computer body, etc.)
- Transport (container construction - heavy machinery - wagons, etc.)
- The thickness of color galvanized sheet is very thin. Currently, the minimum usable thickness of color galvanized sheet is 0.18 mm.
The next thickness is 0.22mm, the next thickness is 0.30mm, the next thickness is 0.40mm, the next thickness is 0.50mm, the next thickness is 0.60mm, and the maximum thickness is 0.70 mm. As colored galvanized sheet is produced in rolls, these rolls are available in standard widths of 100cm and 125cm, so the dimensions must be requested according to these specifications. In the iron market it is usually available in 1*2 or short and 25*1/25 or long sizes. On the other hand, the longitudinal size can be cut and shaped according to the customer's order. For example, you can order 6m, 8m or 4.2m or 3.65m or any other desired length. 
Different coloring sheets
Colored sheets are available in different designs, which you will learn about below. Shadow line Design Swatches: Shadow line design swatches are one of the most popular and widely used types of swatches. The reason for using this product is the high quality of the product. This product is trapezoidal, which, in addition to being light and economical, also has a wonderful aesthetic. This sheet is one of the best-selling colored sheets on the market and is most widely used for the production of sandwich panels and the production of all kinds of roofs. Palermo Pottery Design Color Board: This type of board has good impact resistance and light weight and is quick and easy to install. The reason for naming this table is the name of a city in Italy from which all the roofs of houses in the region are made, the name of this city is Palermo. The thickness of the galvanized layer of this product is between 20-25, so it has good resistance. Trapeze Design Color Board: This board is mainly used for ceilings and shed walls. This sheet is very light and affordable. And it has high resistance and quick and easy installation. Colored louvres or gable panels: Louvres are widely used in the construction of gable roofs. This product is the oldest color sheet. This product is used to beautify products. 
Sinus patch: This patch looks a bit like a trapezoid and can be difficult to distinguish from one another. These products are mainly used for the construction of sheds and buildings. And has high resistance to light and water. Coloring sheet manufacturing steps The galvanized coil is placed in the sheet preparation stage after the production of galvanized sheet. After the plate is prepared, the surface of the plate is ready to be polished. The reason for this is to remove grease and impurities from the metal surface. Use a special roller to brush after degreasing. The purpose of brushing is to make the surface of the plate smooth and uniform so that the coating quality of the galvanized plate is higher. Then they wash the sheets with water and use aeration to dry the sheets. Then, in the next step, the corrosion resistance of the sheet must be improved by spraying a chemical on the surface of the sheet. Then you have to go to the shadow phase. Before painting, a primer layer must be applied to the surface of the board. And after priming, we apply several layers of galvanized paint to the surface of the sheet and then put the sheet in the oven to dry. After the sheet has cooled, he applies the final color to the surface of the sheet. Then put it back in the oven. Products made in this way have excellent resistance and ductility. 
metal sheets
One of the components of metal sheets is chromium, and when it combines with oxygen in the air, a layer of chromium oxide is formed on the steel plate, thereby preventing the steel plate from rusting. Among other positive properties of the steel plate, we can mention its reusability, high hardness, and strength of the steel plate. stainless steel plate Stainless steel plate is another type of steel plate whose matrix is iron and consists of less than two percent carbon. There are different alloys of this plate, and the higher the carbon content of the alloy of this plate, the higher the strength and hardness. There are many types of stainless steel plates, but the most important are 300 and 400 steel. The applications of the 300 series and 400 series of this sheet are different. Acid resistance, coating and fire resistance is one of the most important properties of this steel plate. The 400 series of this sheet is usually used in the manufacture of household tools, but is mostly used in the food industry and pharmaceutical products. aluminum plate As a kind of plate, the aluminum plate is also the most widely used steel plate, which has the characteristics of high strength and lightweight. This table has different types and can be used in different situations. This type of plate is produced by a hot rolling process. The process of making aluminum sheets is to heat the aluminum rod at a high temperature and then pass it through rollers, thereby reducing the thickness of the aluminum sheet. In the final step, the produced product is wrapped in sheets or rolls. 
Aluminum sheets can be supplied to the market in 5000 and 6000 series, each series has its own application. The 6000 series aluminum sheets are called silicon and magnesium, and generally speaking, these two elements are the two main alloying elements that make up these aluminum sheets. At the same time, the 5000 series aluminum sheets are more resistant to salt water corrosion, and there are many models on the market to choose from. The wear layer The higher the carbon content of the alloy plate, the higher its strength and wear resistance. The rolling method is used to produce wear-resistant sheets. There are different types of anti-wear plates. This sheet is used in areas such as quarrying and conveyor belts, material handling and construction. In general, a wear-resistant plate can be said to be a high-carbon alloy plate, and the presence of this carbon increases its strength and hardness. In the chemical composition of the wear layer, there are two important elements, carbon and manganese, which lead to the formation of the iron carbide layer. These types of plates are available in harnesses of 400, 450, 500, 550 and 600 and are named accordingly. There are different types of this type of veneer and depending on its type, they have a wide range of uses in different industries. For example, one of the wear-resistant plates is the Veldox plate, which is mostly used in the automotive industry due to its high strength and good weldability. perforated plate A punched plate is a plate with holes on its outer surface. These sheets are usually punched out by hand or with a CNC machine; the point here is that punched sheets are made from plain sheet metal, punched out in a post-rolling step. 
The pores on the surface of this sheet come in square, round, star and diamond shapes; of course, the circular mesh model of perforated plates is more applicable. This type of plate has many properties, the most important of which are high strength and vibration control. Tin plate A tin plate, also known as sheet metal, is a kind of steel plate. Tin plate is similar to the galvanized plate, but galvanized plate is manufactured with a galvanized layer, whereas tin is manufactured and sold with a tinned layer. Ductility, soldering ability, and bending ability are the most important properties of tinplate. In addition to these conditions, smooth and uniform surface, good paintability and prevention of early erosion are other properties of the board. The use of tin plates depends on the technical, mechanical, and chemical properties of the plate. The most prominent feature of tin plates is the corrosion resistance and iron oxide. Steel has little resistance to rust, and tin metal compensates for this weakness. Hatch table Shadow line sheets are basically colored sheets used to cover the roof of an attic. Shadow line sheets have special features, the most important of which are colors, waves, and coatings. This type of sheet, because it is corrugated, is used to better transfer rain or snow from the roof to the ground. Shadow line sheets are available in a variety of thicknesses and colors. This type has different properties. Shadow line plate is lighter in weight than other steel plates and is resistant to corrosion and iron oxides. This sheet has a lifespan of around 20 or 30 years and can be used in many construction projects because it is coated with a galvanized process. 
Simple introduction of carbon steel In plain carbon steel, carbon is the main alloying element, and elements such as manganese, silicon, and aluminum are added in small amounts for degassing. The carbon content of these steels plays an important role in increasing the strength after heat treatment. These steels are divided into three groups: low carbon, medium carbon, and high carbon
- Mild steel up to 0.25% carbon
- Medium carbon steel with 0.55-0.25% carbon content
- High carbon steel with a carbon content greater than 0.5%
Low-carbon plain steel is used in general engineering parts, shipbuilding, and railways. In addition, these steels have high magnetic properties and good weldability. Low carbon steel plate Mild steel sheets are the most prominent group of malleable steel sheets. The increasing use of these sheets in the automotive and home appliance industries necessitates mass production. According to the steelmaking process, low-carbon steel is divided into two categories: boiling steel and mild steel. 
Annealed steel is steel that has not been deoxidized before solidification. During the solidification process of this type of steel ingot, carbon and oxygen dissolved in the melt react and the molten metal boils due to the formation of CO bubbles. Therefore, bars and plates made of welded steel have a very low carbon surface and are free from defects. To produce mild steel, molten metal is deoxidized by adding aluminum, silicon, or titanium before casting. In recent years, strand casting has largely replaced ingot casting. The necessity of continuous casting of the smoothness of molten metal has resulted in a significant decrease in the production of hot steel.
