Steel plates are steels made from molten steel and most of them are used in industrial buildings. The use of different kinds of steel plates is also not the same. Owners should purchase according to their own needs when they purchase. For example, steel plates that require long exposure to the weather must have good weatherability. What are the types of steel plate materials ? What are their advantages and disadvantages? The following is just a brief look at it with Xiaobian. First, what kind of steel plate material 1, ordinary medium and thick steel plate Ordinary medium and thick steel plates are deoxidized steels. The molten steel of such steels has a high oxygen content. During the production process, a large amount of gas is generated to make the molten steel boil. Therefore, it is also called boiling steel. Advantages: The surface of the steel plate is relatively smooth, of good quality and easy to process. Because this steel plate does not have a concentrated shrinkage cavity, the amount of deoxidizer is small and the price is lower than other steel plates. Disadvantages: This kind of steel has many internal gas contents, too many impurities, bad welding, and the bearing capacity is worse than other steel plates, so it is not suitable for parts that need to withstand gravity. 2, carbon steel calm steel The carbon steel calm steel plate is deoxidized before being produced. When the molten steel is poured into the steel plate, the reaction is calm and there will be no boiling state. Advantages: There is no gas in this kind of steel plate, the impurity is less, the force is very even, and the welding performance is better. Widely used for demanding parts Disadvantages: The quality of the surface of the steel plate is not as good as the boiling plate, there is a centralized shrinkage cavity, the price is more expensive. 3, low alloy structural steel plate Low-alloy structural steel plates are mainly used in the fields of mechanical manufacturing and metal structural components. Advantages: This kind of steel plate has superior performance and lighter weight. Disadvantages: This steel plate is a calm plate, so the price will be more expensive. 4, weathering steel plate with welded structure Welded structural weathering steel plates are made by adding chromium, molybdenum, titanium, vanadium, and other metal materials to common molten steels. Adding these materials can form a protective film on the surface, which can withstand long-term weathering corrosion. Advantages: This kind of steel plate has very good welding performance and weather resistance, and it is widely used in areas such as railways and bridges that require long-term exposure to the atmosphere. Disadvantages: This kind of steel plate has very high requirements for the production process, and the poorer process can not produce good weather resistant steel plates. 5, pattern steel plate The surface of the pattern steel plate has a pattern like a blade, and it should be noted at the time of purchase that the thickness of the pattern protrusion is not included in the thickness of the steel plate itself. Advantages: This kind of steel plate has good decorative performance and good anti-slip effect. Disadvantages: This kind of steel plate production process is more complex, the price will be more expensive than the ordinary steel plate, its mechanical performance requirements are not high. 6, composite steel plate The composite steel plate uses carbon structural steel as a base material and is sprayed with stainless acid-resistant and heat-resistant steel on the surface. It is widely used as an acid and alkali resistant container. Advantages: The appearance of this steel plate is very smooth, the quality is very good and it will not rust. Disadvantages: This kind of steel plate has better requirements for the construction process and the price is more expensive. Editing summary: The above is the type of steel plate material that Xiaobian has shared for you. What is the purpose of their use, and I hope to help you.

ps sheet is a new type of environmentally friendly packaging material developed in recent years. With its excellent thermoforming performance, good defensive performance, environmental performance and hygiene performance, it is widely used in medicine, food, toys, electronics and clothing.
main feature: ps sheet, black ps film, PS lid Shandong Top Leader Plastic Packing CO., LTD , https://www.sdzlplastic.com
1. Low static electricity generation, suitable for packaging products that require low static electricity.
2. Easy to vacuum form, and the product has good anti-attack performance.
3. It has good hygienic properties and can be in direct contact with food without causing harm or benefit.
4. It is easy to be colored and can be made into materials of different colors and produced into vacuum covers of different colors.
5. Good hardness, this kind of sheet material has better hardness than other sheet materials of the same thickness. The thermoformed cup can be used as a hot and cold drink cup.
6. It meets environmental protection requirements and can be recycled and reused. When its waste is incinerated, it does not produce harmful substances that harm the environment.
The main purpose:
1. Low static electricity generation (such as electronic products...)
2. Food packaging (such as: beverages, candy, and meat... packaging)
3. Dairy products (dairy products packaged in polystyrene sheet containers can be placed in a cold storage and will not deteriorate easily;)
