Description

Allied Universal Beams and Columns are engineered for superior load-bearing capacity and structural integrity. As a core component of our Long Products category, these steel sections are essential for modern construction, providing the necessary support for multi-story buildings, industrial complexes, and civil engineering projects.

Technical Specifications & Standards Our structural steel products are rigorously tested to ensure compliance with major international standards. Below are the key specifications available based on our catalog data:

Supported International Standards:

• British / European Standards (BS EN 10025 / BS 4360):

  • Grades: S275JR, S275J0, S355JR, S355J0, S355K2.

  • High yield strength and excellent weldability.

• Japanese Industrial Standards (JIS G 3101 / 3106 / 3136):

  • Grades: SS400, SS490, SS540, SM490A/B, SN400A/B.

  • Optimized for tensile strength and ductility.

• American Standards (ASTM):

  • Grades: A36, A572 Gr.42/50, A992.

  • Widely used for general construction and bridge applications.

• Australian / New Zealand Standards (AS/NZS 3679.1):

  • Grades: 250, 300, 350.

• German Standards (DIN 17100):

  • Grades: St 37-2, St 44-2, St 52-3.

Mechanical Properties Highlight:

• Tensile Strength: Ranges from 400 N/mm² up to 640 N/mm² depending on the specific grade.

• Yield Point: High yield minimums ensuring robust structural performance under load.

• Impact Test: Verified impact energy absorption for grades requiring toughness (e.g., S355J2, SM490B).

Chemical Composition: Strict control over Carbon (C), Manganese (Mn), Silicon (Si), and impurities (P, S) ensures the steel meets the specific “Ladle Analysis” requirements for weldability and durability.
