Roofing sheets have many different types, and the sizes are based on the gauge to mm. The term gauge is well known to those working with sheet metal. But some people may not understand what it means, e.g., 18-gauge steel, they may not understand what it means. This gauge is used to determine the thickness of sheet metal. A meter is not a standard or metric system, its value is independent of other measurement systems. Conversion tables are used to determine plate thickness using gauges. These tables indicate the sheet thickness for each specification value in millimeters or inches. For example, 18-gauge steel represents a 0.0478 inch or 1.214 mm thick steel plate. 
The number 18 here has nothing to do with the actual thickness of the sheet. Today, different measuring systems are used for different types of metals. For example, for carbon steel, a gauge of 18 means a thickness of 0.0478, but for aluminum, a gauge of 18 means a thickness of 0.0403 inches. Measurement systems have a very long history in the steel production industry. It is likely that this system was first used in the UK to make electrical wiring before the advent of standard and metric metering systems. At that time, indicators were used to measure the diameter of a wire under tension. Then the thickness of the plate and the diameter of the wire are measured in this way. The choice of the appropriate plate thickness for a specific application depends on the various tests performed and the chemical and mechanical properties of the plate. Taking the sink as an example, it must be said that most high-quality and heavy sinks are made of 16 or 18 gauge 304 steel plates, which have good resistance.
roofing sheets types
Roofing sheets are popular because of their strength and durability, though they have many types. 
Various materials are used in their construction, such as steel, zinc, polycarbonate, polystyrene, acrylic, PVC, etc. Each of them has a different shape. Some are more durable while others are more textured. To ensure the life of the roof, it is very important to choose the right type of slab. Roofs are often the most durable part of a building in terms of materials. It is always exposed to constant heat and rain and even snow. Seasonal changes first affect the roof and then spread to the rest of the building. it is necessary to protect the roof to ensure the durability of the building. Once the roof is in place, the house is complete. Some things affect the ceiling. They include the cost, needs, and nature of the home. When talking about building a roof, it is important to let natural light through and be absorbed by the slabs. At the same time, it should also be protected under other weather conditions. Homeowners can choose from decorative designs and bedding in a variety of colors they like and fit their budget. 
Corrugated sheets are the strongest roofing sheets and are made of different types of materials. Galvanized steel sheets and polyester painted sheets are some of the most commonly used items in this type of sheet. These plates are suitable for less polluted areas and require maintenance every 5 years. Sheet roofing sheets are mainly used in garages and gardens. They are lightweight and available in different colors and textures. Industrial sheds often use such plates. Depending on the size, a ceiling light panel can be installed that allows light to pass through the ceiling.
roofing sheets gauge to mm
Calculating the diameter of the roofing sheets gauge is also in mm. To understand the method, we better give you some information about it. The steel plate meter refers to the measurement of the size of the steel plate. In some cases, it is necessary to calculate the dimensions of the steel plate. If there is no condition to determine its size from the steel plate, or if the purchase invoice cannot be obtained, the method used to determine the size of the steel plate. 
This process for measuring the dimensions of different types of steel plates is called steel plate meters. In fact, blurring is in other words the same as measuring. As mentioned earlier, different methods are used to determine the size of steel plates. use rope, caliper, French wrenches, steel mesh, etc. to detect and measure the diameter of the steel plate. Sheets are used in the basic form of metalworking and can be cut and bent into various shapes. Countless objects are made of sheet metal. Thicknesses can vary widely, such as thin foil sheets, as well as thicker multi-use sheets, in flat pieces or complex strips, or can be found in rolls weighing up to 5 to 7 tons. In most cases, the thickness of the sheet is always in millimeters. Non-ferrous metals such as aluminum and copper are measured differently, there are different metals such as aluminum, brass, copper, steel, tin, nickel and titanium Platinum metal sheets are also used as catalysts. There are color-coated galvanized steel (PPGI) and color-coated galvanized steel (PPGL). They are zinc and alloy coated plated for corrosion resistance. The properties of these tables help them withstand changing weather conditions. 
roofing sheets quality
The roof is one of the main components and pillars of the house and the quality of the products used is important as well. Roofing sheets are one of the more common roof types in the humid parts of the world, and their beauty gives a special color and glaze to the buildings. A proper roofing sheet must be fully resistant to weather conditions, including snow and rain. On the other hand, its heat resistance is another factor. Various coatings are used for pitched roofs, one of the most popular is galvanized sheet. A tile roof is a cladding of a saddle roof with an overlapping condition, a type of metal saddle roof, the tiles overlap each other when we go from the roof edge to the roof. Tile roofs are available in flat, rectangular, square, and horizontal designs. Tile roofs are considered a superior type of saddle roof because of their popularity everywhere. Tiled roofs have a long life in terms of durability. It is very quick and straightforward to install, and contrary to what many people think, it does not take time at all. 
This ceiling is also economical because you will get an indescribable performance from it at a one-time price. In general, tile roofs are divided into two states: peak and IKO. There are also many sub groups of these two models. Another reason why a tile roof is considered a superior type of saddle roof is its excellent performance, lightweight, attractive appearance, and high flexibility. It is clearly recommended to use this roof with OSB boards. Nevertheless, the use of gable panels for sloping roof facades is still very popular in Iran, which can be attributed to the high resistance of these products as well as their reasonable prices.
big 6 steel roofing sheets
When it comes to steel roofing sheets there are many different types and the big 6 steel sheet producers in the world are as followed. In the discussion of the world's leading manufacturers of galvanized sheets, there is no doubt that China is considered to be the largest producer in the world. According to statistics, in 2016, China accounted for more than 27% of the global market share, second only to China. 
The huge gap between South Korea and China is that galvanized sheet production is number two and South Korea's share of the world market is around 10%. Countries such as Germany, Turkey, Iran, and the United States are also among the largest producers of galvanized sheets in the world. Properly planned, Iran could take a relatively favorable position in galvanized sheet production. It is expected that according to the measures taken and long-term planning, Iran's galvanized sheet production will increase year by year to more than 3 million tons. If we want to look at the two continents in Asia and Europe that produce galvanized sheets in the world, these two continents are the most important continents for the production of this product, it must be said that in Asia there is no doubt that these countries China, South Korea, the United Arab Emirates, India, and Iran are located in Asia respectively, the largest producer of galvanized sheets is in Asia, which accounts for almost 50% of the global market share, which is a very large number compared to others continental In continental Europe, Germany, Italy, Poland, Spain, Turkey, the United Kingdom, and France are the largest producers of galvanized sheet with a total production of around 7 million tons of galvanized sheet per year. This article introduces the main countries that produce galvanized sheets using the available statistics.
steel sheet design for roof
There are many different designs in the market for roofs, and steel sheets are one of the products mostly used in the market for strong and stainless steel roofs. 
Zinc is coated on these boards due to its inherent corrosion and rust resistance and leads to the use of these boards in areas with high humidity. These plates are available in thicknesses between 6 and 18 mm and lengths between 2 and 6 meters. Among the application possibilities for these types of panels are water storage trolleys or tanks, cabinet construction, water and liquid supply pipes, roof construction, etc. This steel plate is manufactured in a cold rolling process and then oiled (direct spraying and closed-circuit spraying) so that it is called an oiled plate, and through this work, it gets a beautiful and shiny appearance. It is produced in different sizes, dimensions, and thicknesses and is easy to bend and shape. These steel plates are used to manufacture household appliances from metal such as refrigerators and washing machines, office equipment, and metal shelves. These plates are made of stainless steel. This type of steel plate is made of galvanized sheet, which is known for their colorful appearance. These types of sheets are available in white, brown, yellow, green, blue, orange, and red, but there are no color restrictions. 
They are rust-resistant due to the production of similar galvanized sheets. Their beautiful appearance has led them to be used for the construction of sheds and household appliances. The type of paint used is electrostatic and has very high durability. First, spray the powder polymer coating on the surface of the plate with a paint sprayer and bake in a grinding oven. Then use a roller to apply the final color to all surfaces and put it back in the oven to bake. These plates are available in thicknesses between 0.8 and 6 mm and widths between 1 and 2.5 meters.
