Carbon Steel Rectangular Tube

Carbon steel rectangular tubes are widely used in various industries due to their strength, versatility, and cost-effectiveness. They are manufactured by forming a rectangular cross-section from a flat steel sheet or coil, followed by welding or seamless forming. Below is a detailed overview of carbon steel rectangular tubes:

Characteristics of Carbon Steel Rectangular Tubes:

1. Material Composition:
Carbon Steel: Primarily composed of iron and carbon, with small amounts of other elements like manganese, silicon, and sulfur. Carbon content typically ranges from 0.05% to 0.25%, depending on the grade.

2. Shape and Dimensions:
Rectangular Cross-Section: The tube has a rectangular shape with four sides.
Dimensions: The size of the tube is specified by its width, height, and wall thickness. Common dimensions range from small tubes (e.g., 1" x 2") to larger tubes (e.g., 12" x 8").
Wall Thickness: The thickness of the tube walls can vary, with common ranges from 1.5mm to 12.5mm or more.

3. Surface Finish:
Hot-Rolled: Tubes with a rougher surface finish, suitable for structural applications.
Cold-Rolled: Tubes with a smoother, more refined surface, often used in applications requiring higher precision and aesthetics.

4. Grades:
Mild Steel Grades: Common grades like ASTM A500, A513, and A36 are used in structural and general-purpose applications.
Higher Carbon Grades: For applications requiring increased strength and wear resistance, higher carbon grades like ASTM A106 may be used.

Applications of Carbon Steel Rectangular Tubes:

1. Construction and Structural Uses:
Building Frames: Used in construction for columns, beams, and supports due to their strength and ability to bear heavy loads.
Bridges: Commonly used in the fabrication of bridge components, such as trusses and girders.
Machinery Frames: Ideal for frames and supports in heavy machinery and equipment due to their rigidity and load-bearing capacity.

2. Fabrication and Manufacturing:
Automotive Industry: Used in the construction of vehicle frames, chassis, and roll cages due to their strength and lightweight properties.
Furniture Making: Used in modern and industrial-style furniture for creating sleek, durable frames.
Metal Fabrication: Widely used in the fabrication of various metal products, including storage racks, conveyors, and equipment housings.

3. Transportation and Infrastructure:
Railings and Guardrails: Used for safety railings, barriers, and guardrails in highways and industrial facilities.
Transportation Systems: Used in the construction of various transportation systems like buses, trucks, and trailers.

4. Agricultural Equipment:
Farm Machinery: Commonly used in the fabrication of farm machinery, including plows, trailers, and storage structures.
