Q235 Rectangular Steel Pipe is a high-strength, cost-effective carbon steel structural pipe with a rectangular cross-section. It is widely used in construction, manufacturing, and various engineering projects due to its excellent mechanical properties and ease of processing.

Product Overview

Q235 Rectangular Steel Pipe is made from Q235 carbon steel, a common carbon structural steel grade in China. This grade denotes a yield strength of 235 MPa. The pipe is characterized by its rectangular (oblong) or square hollow section. It is primarily manufactured using the ERW (Electric Resistance Welding) technique, which ensures a strong and precise weld seam.

Key Features & Advantages

Q235 Rectangular pipe offers a compelling combination of properties:

High Strength & Good Load-Bearing Capacity: The rectangular shape provides excellent structural strength and moment of inertia, making it resistant to bending and twisting under heavy loads. This is ideal for structural frameworks and supports.

Excellent Weldability and Processability: Q235 material is known for its good welding performance. The pipe can be easily welded, cut, punched, bent, and fabricated into various structures and components, reducing processing difficulty and cost.

Cost-Effective: Compared to other alloy steels, Q235 carbon steel offers a lower cost while providing reliable mechanical properties, ensuring a high price-performance ratio.

Durable: While carbon steel's inherent corrosion resistance is limited, Q235 rectangular pipes are often available with surface treatments like galvanization (zinc coating) or painting to significantly enhance rust resistance and prolong service life.

Variety of Specifications: Available in a wide range of sizes and thicknesses to meet diverse project requirements.

Applications

Q235 Rectangular Pipes are versatile and used in numerous sectors:

Construction & Infrastructure: Building structures, steel frames, support columns, guardrails, roof trusses, and purlins.

Machinery & Equipment Manufacturing: Fabricating machine bases, frames, support racks, conveyor systems, and various mechanical parts.

Automotive and Transportation: Used in vehicle chassis, trailer bodies, and structural components.

Furniture and Displays: Creating sturdy frames for industrial shelving, workbenches, exhibition stands, and modern furniture.

General Engineering: Any application requiring a strong, lightweight, and easily fabricable structural component.
