Rolled steels refer to steel products that are formed into desired shapes through the rolling process. They are commonly used in various industries, including general structure applications.

General structure refers to the use of steel in structures that do not have specialized requirements, such as residential and commercial buildings, bridges, and infrastructure. Rolled steels offer several advantages in these applications, including their high strength, durability, and versatility.

Some commonly used rolled steels for general structure applications include:

1. Mild steel: Also known as low-carbon steel, mild steel is one of the most commonly used rolled steels. It has a relatively low carbon content, which contributes to its good formability and weldability. Mild steel is suitable for general structure applications that require moderate strength and good ductility.

2. High-strength low-alloy (HSLA) steel: HSLA steels are a type of rolled steel that contains small additions of alloying elements, such as copper, nickel, or vanadium. These alloys enhance the strength, toughness, and resistance to corrosion and atmospheric conditions. HSLA steels are used in general structure applications that require higher strength and improved mechanical properties compared to mild steel.

3. Carbon steel: Carbon steels are an alloy of iron and carbon, with small amounts of other elements. They are known for their high tensile strength and hardness. Depending on the carbon content, carbon steels can be further categorized into low carbon steel, medium carbon steel, and high carbon steel. Carbon steel rolled products are commonly used in general structure applications that require high strength and hardness.

4. Stainless steel: Stainless steel is a type of steel that contains high chromium content, which provides excellent corrosion resistance. It is commonly used in general structure applications that require resistance to moisture, chemicals, and other harsh environments. Stainless steel rolled products are chosen based on the specific grade and properties required for the application.

These rolled steels can be manufactured in various forms, such as sheets, plates, bars, and structural sections. The selection of the appropriate rolled steel for general structure applications depends on factors such as the required strength, formability, weldability, and resistance to corrosion or other environmental conditions.

It is important to consult with steel suppliers or professionals in the field to determine the best type and form of rolled steel for specific general structure applications.
