Mild Iron Ss400 Carbon Steel Angle Bar Grade Q235 Angle Profile Steel Angle Iron with Low Prices

Product Overview

Our Q235/SS400 mild carbon steel angle bar, also known as angle profile steel or angle iron, is a high-quality structural steel product engineered for versatility and reliability in industrial and construction applications. As a widely recognized grade in carbon steel classifications, Q235 (equivalent to SS400) represents a cost-effective solution without compromising on mechanical performance, making it a preferred choice for projects requiring both structural integrity and economic efficiency.

Material & Mechanical Properties

Constructed from mild carbon steel, this angle bar features a carbon content range of 0.12%-0.20%, which imparts excellent weldability, formability, and machinability. The Q235/SS400 grade adheres to international standards (GB/T 700 for Q235, JIS G3101 for SS400), ensuring consistent mechanical properties: tensile strength of 370-500 MPa, yield strength of ≥235 MPa, and elongation of ≥26%. Its low carbon content minimizes brittleness and enhances corrosion resistance in ambient environments, while the inherent ductility allows for bending, cutting, and fabrication into custom configurations without structural degradation.

Structural Design & Specifications

The angle bar is characterized by its L-shaped cross-section, with two legs (equal or unequal length) forming a 90° angle-an optimized design that distributes weight evenly and provides exceptional load-bearing capacity. Available in a comprehensive range of dimensions, including leg widths from 20mm to 200mm, leg thicknesses from 3mm to 20mm, and lengths from 6m to 12m (custom lengths available upon request), it can be tailored to meet the requirements of diverse structural projects. The precision-manufactured cross-section ensures tight dimensional tolerances, facilitating easy assembly and compatibility with other structural components.

Key Advantages & Applications

Beyond its competitive pricing, this carbon steel angle bar offers numerous advantages: superior structural stability, resistance to deformation under heavy loads, and compatibility with various joining methods (welding, bolting, riveting). Its applications span across multiple industries, including:

Construction: Framing, trusses, supports for buildings, bridges, and infrastructure

Manufacturing: Machinery frames, equipment bases, conveyor systems, and fabrication parts

Engineering: Bracing, reinforcement, and structural components for industrial plants

Furniture & Fixtures: Shelving units, racks, and architectural accents

Quality Assurance

Each batch of angle bar undergoes strict quality control procedures, including chemical composition analysis, mechanical performance testing, and dimensional inspection, to ensure compliance with international standards. The surface is treated with anti-rust oil or hot-dip galvanization (optional) to enhance durability and extend service life in harsh environments.
