ភាសាខ្មែរSteel plates are known as one of the basic construction materials for buildings. One of the steel plates many people use is the S275JR steel plate. Surely, many people do not know much about this product. Today. Bao Tin Steel would like to introduce the basic information about the S275JR steel plate and its application in the market.
What is the S275JR steel plate?
Basic concepts about S275JR steel plate
Steel plate is known as one of the products of the mechanical industry, a material used in construction projects. Steel plates have a specific shape for use in certain projects and fields.
To produce an S275JR steel plate, it is necessary to go through a complex and high-tech steel refining process. After a complex refining process, the steel will be cast into blocks or plates, depending on usage needs.
Steel refining steel plates usually have lower carbon levels than other steel plates. Because of its lower carbon content, the S275JR steel plate is often used to weld joints.
In 1990, the S275JR steel plate was evaluated according to international standards and recognized by the European Iron and Steel Standards Council. During the research process, the S275JR steel plate could withstand a minimum bending force of 275N/mm2, so it was named the S275JR steel plate.
Steel plates are one of the most basic and important materials in fields such as shipbuilding, barrel building, boat building, factory construction, hydroelectric projects, and factory construction. Bucket,…
Structure of S275JR steel plate
This S275JR steel plate is popular and well-known for having a lower carbon content than other steel plates. Common sizes of S275JR steel plate are:
- Thickness: 0.3 – 10cm.
- Width: 150 – 200cm.
- Length: 600 – 1200cm.
S275JR steel plate has the following chemical composition table:

Classifications of steel plates on the market
With diverse customer needs, new types of steel plates are gradually appearing on the market to easily satisfy customers.
Cold rolled steel
Cold-rolled steel plate can be understood as a type of steel that is rolled thinly at a normal temperature. Use a solvent temperature regulator to create a room-temperature environment during lamination. This is a type of steel plate that appeared first and has wide applications. With cold rolling at low temperatures, the surface of the steel plate is very beautiful and eye-catching. The surface of the steel plate is very shiny.
Cold-rolled steel plate usually have a thickness of 0.5–2 cm. Because they are cold rolled, the steel sheets do not change in chemical composition or properties. This type of steel will be affected by external factors such as rain, sun, etc., so it is suitable for indoor use.
Hot rolled steel
This is a type of steel that requires high technology and technique and was newly created in recent years. This hot-rolled steel will be rolled thinly using a specialized rolling machine at temperatures higher than 1000 degrees Celsius. Normally, when using hot rolling, the chemical composition and properties of the steel may change slightly but not significantly. Hot-rolled steel often has a characteristic dark blue color, and the edges of the steel plate when rolled are not as sharp as when cold-rolled.
Because the chemical composition and properties have changed when hot-rolled, they are more durable. Hot-rolled steel is easy to preserve anywhere and can be used outdoors without wear and tear. This type of steel is durable, so it is often used in warehouses, factories, pre-engineered steel buildings, etc.
