High-Quality Q235B Carbon Steel Angle Iron, 12m Length

Our high-quality Q235B carbon steel angle iron, featuring a standard length of 12 meters, is a premium structural component engineered to meet the stringent requirements of diverse industrial and construction applications. As a classic grade of carbon structural steel, Q235B is widely recognized for its reliable performance and versatility, while the fixed 12m length offers enhanced convenience in project planning and material utilization, making this angle iron a preferred choice for engineers and contractors worldwide.

The core advantage of this product lies in its adoption of Q235B carbon steel, a material that complies with Chinese national standard GB/T 700-2006. Q235B carbon steel boasts a well-balanced chemical composition, typically containing 0.12%-0.20% carbon (C), 0.30%-0.65% manganese (Mn), and controlled levels of harmful impurities (phosphorus ≤ 0.045%, sulfur ≤ 0.045%). This composition endows the steel with excellent mechanical properties, including a minimum yield strength of 235 MPa and a tensile strength of 370-500 MPa. Notably, the "B" grade indicates that the steel undergoes impact testing at 20°C, ensuring superior toughness and resistance to brittle fracture-critical attributes for structural components subjected to dynamic loads. Additionally, Q235B exhibits outstanding weldability and formability, allowing for seamless cutting, drilling, bending, and assembly without compromising structural integrity.

A key specification of this angle iron is its fixed 12-meter length, which is meticulously controlled during the manufacturing process to ensure dimensional accuracy. The 12m length is a highly practical choice for large-scale construction and industrial projects, as it reduces the number of joints required in structural installation, thereby enhancing overall structural stability and construction efficiency. This length also minimizes material waste, as it can be easily tailored to specific project dimensions through precise cutting, adapting to the unique requirements of different applications such as building frameworks, bridge supports, and machinery bases.

Manufactured via advanced hot-rolling technology, this Q235B carbon steel angle iron further enhances its structural performance. During hot rolling, the steel billet is heated to a high temperature (1100-1250°C) and then rolled into the precise angle profile, which refines the grain structure of the steel, eliminates internal defects, and improves its overall toughness and durability. The hot-rolled surface (natural black oxide finish) features a uniform texture and tight dimensional tolerances, ensuring consistent cross-sectional geometry that enables uniform stress distribution when integrated into structural systems. Each batch of angle iron undergoes rigorous quality control inspections, including chemical composition analysis, mechanical property testing, and dimensional accuracy verification, to ensure compliance with Q235B standard requirements.

This high-quality Q235B carbon steel angle iron (12m length) finds extensive applications in a wide range of fields, including residential and commercial building construction (roof trusses, wall frames, staircases), infrastructure projects (highway guardrails, bridge accessories), machinery manufacturing (equipment frames, brackets), and shipbuilding. Its reliable load-bearing capacity, excellent processability, and convenient 12m length make it suitable for both small-scale renovations and large-scale engineering projects.

In summary, our high-quality Q235B carbon steel angle iron with a 12m length combines the superior performance of Q235B material with the practicality of a fixed long length. Backed by strict quality control and advanced manufacturing technology, it provides a cost-effective and reliable structural solution for various applications. Whether for standard construction needs or customized engineering projects, this angle iron delivers consistent performance and long-term durability.
