Q235B 300X150mm Profile H-Beam Price I Ipe Angle Beam H Section Steel

The Q235B 300×150mm profile H-beam is a high-performance structural component, engineered with precision for diverse steel construction projects, complemented by compatible I beams, IPE beams, and angle beams. As a core H section steel product, it is fabricated from the widely recognized Q235B structural steel grade, featuring a standardized 300×150mm cross-sectional profile, and integrates superior mechanical properties, excellent processability, and structural stability-making it a reliable and cost-effective choice for modern civil engineering, industrial construction, and modular building applications.

At the core of this product's performance is the Q235B structural steel grade, a mild carbon steel compliant with Chinese National Standard (GB/T 700-2006). Renowned for its balanced mechanical properties and cost-efficiency, Q235B is a staple in global construction, offering a minimum yield strength of 235 MPa and a tensile strength range of 370-500 MPa. This grade exhibits excellent ductility, weldability, and formability, requiring no special preheating for cutting, bending, or welding-critical advantages for on-site processing and assembly, and ideal for light to medium-load structural applications where reliability and affordability are prioritized.

The 300×150mm cross-sectional profile is a key distinguishing feature of this H-beam, designed to optimize structural efficiency and load-bearing capacity. The 300mm nominal depth and 150mm flange width create a well-proportioned H-shaped cross-section, consisting of parallel top and bottom flanges and a rigid central web. This configuration ensures uniform stress distribution: the flanges effectively bear bending moments, while the web resists shear forces, resulting in an exceptional strength-to-weight ratio. Compared to conventional I beams or smaller H-section profiles, the 300×150mm Q235B H-beam offers enhanced rigidity and load-bearing capability, making it suitable for primary and secondary load-bearing components in medium-span structures.

Manufactured through advanced hot-rolling technology, the Q235B 300×150mm H-beam guarantees consistent quality and structural integrity. During production, Q235B steel billets are heated to precise high temperatures (typically 1100-1250°C) and formed into the 300×150mm profile via a series of precision rolling mills. This process refines the metal grain structure, eliminates internal defects such as porosity and inclusions, and imparts uniform mechanical properties throughout the beam. The result is a product with stable dimensional accuracy, a smooth surface finish, and high durability, capable of withstanding the rigors of construction and long-term service in various environmental conditions.

This H-beam is fully compatible with other structural components mentioned, including I beams, IPE beams, and angle beams, forming a comprehensive structural system for diverse construction scenarios. IPE beams, adhering to European standards, feature a compact cross-section with sloped flanges, ideal for secondary load-bearing applications where space efficiency is key; angle beams provide versatile bracing and connection solutions, while the 300×150mm Q235B H-beam serves as the core load-bearing backbone. Together, these components enable seamless integration into steel frames, industrial workshops, commercial buildings, residential structures, and auxiliary infrastructure.

The Q235B 300×150mm H-beam's design is optimized for practical construction applications. Its parallel flanges facilitate easy bolted and welded connections with other structural components-such as node plates, steel columns, floor slabs, and bracing systems-streamlining on-site assembly, reducing construction time, and ensuring structural stability. Additionally, the standardized 300×150mm profile ensures compatibility with prefabricated modular construction, further enhancing construction efficiency and cost-effectiveness.

Strict quality control measures are implemented throughout the production process, from raw material inspection and hot-rolling forming to dimensional testing and mechanical performance verification. Each batch of Q235B 300×150mm H-beams undergoes rigorous testing to ensure compliance with GB/T 700-2006 standards, guaranteeing consistent performance and structural safety. As a mild carbon steel product, it is also highly recyclable, with a scrap recycling rate of up to 90%, aligning with the principles of green and sustainable construction.

In summary, the Q235B 300×150mm profile H-beam, paired with compatible I beams, IPE beams, and angle beams, offers a robust, versatile, and cost-effective H section steel solution for modern construction. Its Q235B material strength, optimized 300×150mm profile, and compatibility with other structural components make it an ideal choice for engineers, contractors, and project owners seeking reliable load-bearing solutions for residential, commercial, and industrial construction projects worldwide.
