Classification and type of steel plate
Steel plate is a kind of metal material widely used in construction, machinery, automobiles, ships and other fields, and its types and models are various.
Types of steel plates
1. Sort by thickness
According to the thickness of steel plate can be divided into thin plate, medium plate, thick plate, extra thick plate and so on. Among them, the thin plate generally refers to the thickness of the steel plate below 4.5mm, the middle plate refers to the thickness of the steel plate between 4.5mm and 20mm, the thick plate refers to the thickness of the steel plate between 20mm and 60mm, and the extra thick plate refers to the thickness of the steel plate more than 60mm.
2. Classified by production process
Steel plate according to the production process can be divided into hot rolled steel plate, cold rolled steel plate, galvanized steel plate, color coated steel plate and so on. Among them, the hot rolled steel plate is rolled by high temperature heating, the surface is rough, but the strength is higher; Cold rolled steel plate is rolled at room temperature, the surface is smooth, high precision; Galvanized steel plate is plated with a layer of zinc on the surface of the steel plate to prevent the steel plate from rusting; The color coated steel plate is coated with a layer of color paint on the surface of the steel plate, which has a beautiful and generous appearance.
3. Categorize by use
Steel plate can be divided into structural steel plate, bridge steel plate, boiler steel plate, container steel plate, wear-resistant steel plate, corrosion resistant steel plate and so on. Among them, structural steel plates are mainly used in the manufacture of buildings, Bridges and other structures; Bridge steel plate is specially used for bridge construction; Boiler steel plates and container steel plates are used to manufacture boilers and pressure vessels; Wear-resistant steel plates and corrosion-resistant steel plates are respectively used for wear-resistant and corrosion-resistant occasions.
Steel plate model
The type of steel plate is mainly determined by its material, use, thickness, width and other factors. Below are some common steel plate models.
1.Q235B steel plate
Q235B is a kind of low-carbon structural steel plate, with good toughness and plasticity, easy processing and welding, widely used in buildings, Bridges, vehicles, ships and other fields. The thickness range is generally 1.2mm to 60mm, and the width range varies according to different production standards and applications.
2.Q345B steel plate
Q345B is a low-alloy high-strength structural steel plate with high strength and good toughness, which is suitable for the manufacture of structural parts requiring high strength, such as Bridges, high-rise buildings, vehicles and so on. Its thickness range is generally 4mm to 100mm, and the width range also varies according to different production standards and uses.
3.SPCC steel plate
SPCC is a kind of cold-rolled carbon steel plate with smooth surface and high precision, which is suitable for manufacturing parts requiring high surface quality, such as home appliance shell and office furniture. The thickness range is generally 0.3mm to 3.0mm, and the width range varies according to different production standards and applications.
4.SGCC steel plate
SGCC is a galvanized carbon steel plate, the surface is plated with a layer of zinc, has good corrosion resistance, suitable for the manufacture of parts requiring corrosion resistance, such as building exterior walls, roofs and so on. Its thickness range is generally 0.18mm to 3.0mm, and the width range also varies according to different production standards and applications.
In addition to the several common steel plate models introduced above, there are many other types of steel plates, such as wear-resistant steel plates, corrosion resistant steel plates, stainless steel plates, etc., each steel plate has its specific use and characteristics. In practical applications, the appropriate type and type of steel plate need to be selected according to the specific use environment and requirements.
In short, as an important metal material, steel plate has a wide range of applications in various fields. Understanding the types and models of steel plates is of great significance for the correct selection and use of steel plates.
