Zinc or Aluzinc plate is a coated plate, as the name suggests, an alloy of aluminum and zinc is used to coat the plate. In addition to these two elements, silicon also participates in its composition in a very small percentage. The percentage of each element in this alloy composition includes: 55% aluminium, 43. 4% zinc and 1. 6% silicon. This coated plate is highly resistant to moisture, oxidation, and rust and does not rust in any way. The alloy composition of the sheet increases the electrical resistance of the galvanized sheet by a factor of 6 compared to the galvanized sheet. Therefore, it is widely used in construction and industry. Aluminum-zinc sheets are divided into 4 types based on how they are presented, including:

  • Aluminum zinc plate flat coil
  • Aluminum zinc plate
  • Specially shaped galvanized plate
  • Stripping of aluminum zinc sheets
  • Color aluminum zinc plate

As we said, there are many different types of sheet metal, each of which is used in different industries according to its properties. Aluminum-zinc sheet is no exception, due to its anti-rust properties and other advantages, it has a very wide range of applications in industry. These applications include:

  • Carpentry and refrigerator manufacturing
  • make sandwich panels
  • Make different traffic signs
  • Air conditioning and cooling tunnels
  • In the production of construction, roof tiles, wall coverings, and sealants or rinsing

How to produce Aluzinc plate Two methods, electrolysis, and impregnation, are used to produce galvanized sheets, which are not normally used in Iran due to problems related to power consumption. Almost all factories use the hot dip method to make this sheet. First of all, it is necessary to determine the percentage by weight of the elements required for the alloy of the sheet according to the production standard for the galvanized sheet. The production steps for this sheet are as follows:

  • Sheet thickness is reduced by cold rolling.
  • The sheets were washed and degreased.
  • The sheet enters the annealing furnace and protects the atmosphere.
  • It is then immersed in a bath of molten elements.
  • It is combined with the elements aluminium, zinc, and silicon to make coatings.
  • Finally, they perform a chromate operation to prevent the paper from flake.

Most of the production steps of the galvanized sheet are similar to the galvanized sheet. After these steps, the produced original sheet is put into an oven for heat treatment while the desired color is sprayed on it to make a colored galvanized sheet. Comparison of galvanized sheet and galvanized sheet Galvanized sheet and galvanized sheet have many similarities. These plates are made of sheet steel and they are all considered to be coated. The main difference between them is the type of cover. The galvanized plate cover is made of zinc, while the material of the galvanized plate cover is an alloy of aluminum and the element zinc. galvanized steel panels

Difficulty is different Due to the high aluminum content in its composition, Galvalume is 2 times harder than the galvanized sheet. As a result, Galvalume sheets are more resistant to wear and corrosion. Appearance difference The appearance of the Galvalume sheet is more uniform and beautiful, and if the sheet is dented due to pressure, it can be easily restored to its original state before impact. In addition, this sheet is usually produced in painted form with small and plain sequins. The appearance of the galvanized sheet is colorless and shiny. The difference in flexibility Galvanized sheet has more and higher flexibility than the galvanized sheet. Differences in size and density In terms of size, both plates are limited in size, but galvanized plates are produced in a wider range. The thickness of the galvanized sheet is between 0. 5 and 2. 0 mm, and the thickness of the galvanized sheet is between 0. 5 and 0. 8 mm. At the same thickness, the density of aluminized zinc coating is lower than that of the galvanized coating. Different coloring methods galvanized steel sheet

Galvanized sheet is generally colorless, but if it is produced in colored form, it is made of a colored galvanized sheet, which is a type of galvanized sheet. Galvanized sheet is usually manufactured as a colored sheet and is painted with oven paint to make it more durable. These sheets are produced according to different standards and the products produced according to these standards have specific applications. Types of aluminum zinc sheets manufactured using different applications include: Generally use the galvanized plate, generally use hot plate bottom, generally use high strength, generally use high strength hot bottom, semi-deep drawing, and deep drawing. These standards also include:

  • American Standard ASTM A792/A792 M-10 (2015)
  • Japanese material standard JIS G 3321
  • EN 10346:2015 replaces BS EN 10327:2004 and BS EN 10326:2004
  • EN 10215
  • INSO 18863

These sheets have regular, regular, and needle-like sequins on the surface, which affects the quality of the sheet. Sheets made with fine sequins are generally used for dyeing and making colored galvanized sheets. The finished plate can withstand a high temperature of 400 degrees without discoloration, and the painted plate can withstand a high temperature of 600 degrees without rusting. galvanized steel pipe

Steel plates and galvanized steel plates get the price in kilograms, tons, or pounds, and come in many types, one of which is tin, depending on the application and the properties required by the price industry. This plate is a steel plate coated with tin metal, which inhibits corrosion and rust on the plate and gives it many properties. This plate, also known as tin plate, is a low-carbon steel plate that belongs to the cold plate category and is produced by cold rolling. The tin coating on its two surfaces can be of different thicknesses, causing the overall thickness of the plate to vary. This product is very similar to the galvanized sheet. The base for both is made of steel, the difference being that the cover plate on the galvanized plate is zinc metal and the cover plate on the tin plate is tin metal. Tin metal is silvery white, very light and melts easily. This metal is not used in its pure form, to use it, tin metal is combined with other elements to create an alloy with the properties of tin. The resulting alloy is less toxic and has high corrosion resistance. The properties that tin coatings provide to such sheets make them suitable for a variety of applications ranging from construction to industrial, such as construction, roofing, fencing, pots, trays, food packaging, pharmaceuticals, chemicals, and more. Types of tin plates The tin plate is divided according to various factors such as size, use, appearance, thickness, the alloy used, hardness, and softness. We will introduce them here. Sheets classified by appearance One of the determining factors for the type of tin is its appearance, during a series of operations performed on it, tin comes in different colors and types. 1 Matt It has a black unpolished finish with a silver gray finish. During the printing process, it causes the ink to stick to the paper used to print the cans and caps. 2 Grinding It has a fused finish. This type of application is practical and the strong line is suitable. 3 Grinding in large size It has a fused finish. It has high scratch resistance and is therefore easy to use during the coating process. It is also used in the production of the top and bottom of the tank. 4 silver It has a fused finish and a glossy finish, giving it an attractive silver look when glazed. This type is used to make caps and decorative jars. 5 gloss It has a fused finish that creates a natural finish for regular looks. This method has been used in the past to make tinplate, but only a small percentage (about 6%) is currently made in this way. galvanized steel price per pound

Today, the electrolytic method has replaced the dipping method, greatly reducing the production cost of tin. One of the disadvantages of this method is that it is impossible to tin both sides of the board evenle 2 Electrolysis In the electrolyte method, a pool of water and acid is used. The steel plate is cleaned first and then goes into the pool. Then enter the acid pool and re-enter the pool for cleaning. In this way, the coating of both sides of the steel plate is completed. In the final phase of drying, quality control and packaging are carried out. In this method, the quality of the product can be controlled, which is one of the important advantages of electrolysis. Production steps of tin To make this type of sheet, you must first prepare the sheet. The raw material is steel plate, which must be hot-rolled and then cold-rolled to achieve the desired thickness. After hot rolling the steel plate, acid is used to remove the oxide layer formed during the rolling of the steel plate. These sheets are used to make food packaging products. For this purpose, the plates are acid washed in an acid bath to remove any harmful substances or iron oxides from the plates so as not to endanger human health Cold rolling and carpentry As we said, both cold rolling and hot rolling are used to produce this type of sheet. In this step, in order to reduce the thickness of the plate, the plate is subjected to a cold rolling process, and special rollers are used to reduce the thickness of the plate. The thickness of this plate is very important, the desired final thickness is between 0. If the thickness of the sheet is greater or less than this value, the sheet will lose its formability or its strength will decrease. This step is performed to remove grease and impurities that were created on the surface of the sheet in the previous step. After the initial cleaning, a second step called electrolytic degreasing takes place. In this step, the plate is placed in an alkaline bath of alkali so that an electric current can pass through the plate. During this work, the sheet was peeled off and its surface contamination was removed After cold rolling and thinning, the sheet loses flexibility and becomes hard. In this step, physical and chemical changes are applied to the sheet to repair its fragility of the sheet. To anneal the plates, they pass through vertical rings inside the furnace and remain in the furnace for 2 minutes at 680 degrees. Insertion in the oven prevents oxidation of the sheet and increases its flexibility of the sheet. In most cases, after annealing, the plate becomes too soft and loses strength. For this reason, they must undergo a different process to restore the required strength and standard. To do this, the sheet is placed in rollers at a temperature below the annealing stage and passed through them. After performing this step, the surface of the sheet is smooth and the strength is increased to the required standard. This phase is one of the last phases. Here, the steel plates are placed on a ring plate, so that both surfaces are completely covered with tin, and the plates are attached to this by welding. Tin or chromium is used for this process. galvanized steel tubing
