Q235 100X100X6 Steel Iron Angle, a high-quality mild steel angle, is a specialized structural product engineered with premium Q235 mild carbon steel and fixed standard dimensions of 100mm×100mm×6mm. Characterized by its symmetrical L-shaped cross-section, excellent workability, and reliable mechanical performance, this mild steel angle adheres to the Chinese national standard GB/T 700, making it a cost-effective and versatile structural component for various industrial, construction, and mechanical applications that demand stable load-bearing capacity and easy fabrication.
The core performance of this mild steel angle is determined by its Q235 mild carbon steel material, a widely used grade renowned for its balanced properties and cost-effectiveness. Q235 mild steel features a strictly controlled chemical composition: carbon content ranging from 0.14% to 0.22%, manganese content of 0.30% to 0.70%, and trace amounts of silicon and phosphorus. This optimized composition ensures the material exhibits exceptional ductility and toughness, with a minimum yield strength of 235 MPa and a tensile strength range of 370-500 MPa-perfect for medium-load structural applications where both strength and workability are critical.
The fixed 100X100X6mm specification is a key feature tailored for practical structural needs, with the "100X100" referring to the symmetrical leg length (100mm on both sides) and "6mm" indicating the uniform thickness of the legs. This dimension is standardized to ensure consistent force distribution across the L-shaped profile, effectively reducing stress concentration and enhancing structural stability. The symmetrical design makes it ideal for symmetrical structural connections, frame bracings, and vertical supports, while the 6mm thickness provides sufficient rigidity to withstand moderate static and dynamic loads in various scenarios.
As a mild steel angle, this product boasts outstanding workability, a defining advantage for structural fabrication. Its low carbon content enables seamless welding using standard methods (arc welding, MIG welding, TIG welding) without the risk of brittleness or cracking in the heat-affected zone, ensuring strong and durable joints with other structural components. Additionally, it can be easily cut, drilled, and bent using conventional industrial equipment, adapting to customized project designs without compromising its structural integrity.
Manufactured using advanced hot-rolling technology, the Q235 100X100X6 Steel Iron Angle undergoes a precise production process to guarantee consistent quality and dimensional accuracy. Steel billets are heated to temperatures above 1000°C to soften the material, then subjected to precision rolling to form the symmetrical L-shaped cross-section. This hot-rolling process refines the internal grain structure, eliminates inherent defects such as pores, inclusions, and microcracks, and enhances the material's ductility and toughness-ensuring uniform performance across the entire length of the angle.
In terms of application versatility, this Q235 mild steel angle is widely used in various fields due to its reliable performance and standardized dimension. In construction engineering, it serves as a core component for building frames, roof trusses, floor joists, balcony railings, and scaffolding. In industrial fabrication, it is utilized as machinery supports, equipment bases, factory frameworks, and conveyor system brackets. It also finds applications in infrastructure projects, such as road guardrails, drainage system supports, and small-scale bridge bracings, as well as in warehousing and civil decoration.
Each batch of Q235 100X100X6 Steel Iron Angle undergoes rigorous quality control procedures to ensure compliance with GB/T 700 standards. Inspections include chemical composition analysis to verify the purity of Q235 mild steel, mechanical property testing (yield strength, tensile strength, impact toughness), dimensional accuracy verification to ensure the 100X100X6mm specification is strictly maintained, and surface quality assessment. The natural hot-rolled surface can be further treated with hot-dip galvanization, electro-galvanization, or painting to enhance corrosion resistance, extending its service life in outdoor, humid, or corrosive environments.
As a standardized, cost-effective mild steel angle, the Q235 100X100X6 Steel Iron Angle embodies the perfect balance of performance, workability, and affordability. Its fixed dimension, reliable Q235 material, and excellent fabrication properties make it an indispensable structural component for modern engineering projects, catering to the diverse needs of construction, industrial, and infrastructure applications worldwide.
