This material grade features a minimum yield strength of 345MPa (50ksi) and a tensile strength ranging from 450MPa to 600MPa, delivering exceptional strength-to-weight ratio, superior to ordinary carbon structural steels. It also boasts excellent toughness, fatigue resistance and ductility, effectively resisting deformation and fracture under dynamic loads and complex stress conditions. Additionally, ASTM A572 Grade 50 steel exhibits outstanding weldability, cutting performance and machining adaptability, supporting conventional construction processing techniques without requiring complex pre-treatment or post-treatment procedures, which greatly improves construction efficiency and reduces engineering costs.

3. Profile Specifications & Structural Features of Each Model

This H-beam series covers four classic European standard models, namely IPE 270, IPE 300, HEB 260 and HEA 200, each with unique structural attributes to meet differentiated engineering load-bearing and installation requirements, with uniform dimensional tolerances in line with European steel structure standards.

3.1 IPE Series (IPE 270 & IPE 300)

The IPE series belongs to European standard I-shaped steel profiles with parallel flanges, featuring a slender web and moderately sized flanges, optimized for bending resistance and lateral stability. IPE 270 and IPE 300 are medium-sized specifications in the series, with lightweight design and moderate section modulus, suitable for secondary load-bearing components in steel structures such as secondary beams, purlins, frame trusses and auxiliary supports. Their compact structure and controllable self-weight make them easy to transport, hoist and assemble, ideal for medium-load steel structure systems, balancing structural performance and construction convenience.

3.2 HEA & HEB Series (HEA 200 & HEB 260)

HEA 200 is a light wide-flange H-beam, characterized by relatively thin flanges and web, lower unit weight and cost efficiency, suitable for light to medium-load structural components and space-limited installation scenarios, ensuring basic load-bearing capacity while optimizing material usage.HEB 260 is a heavy wide-flange H-beam, with wider and thicker flanges and a stiffer web, possessing larger section modulus and stronger compression, bending and torsion resistance. It serves as a core primary load-bearing member for steel structures, applicable to main beams, frame columns and key support parts in heavy-duty projects, providing robust structural rigidity and long-term stability.
