H-beams, also known as wide-flange beams or universal beams, are structural steel beams with an H-shaped cross-section. Specifications for H-beams can vary depending on the international standards followed.
Some of the common international standards for H-beams include:
- American Standard (ASTM A992/A572):
- ASTM A992/A992M: Standard Specification for Structural Steel Shapes
- ASTM A572/A572M: Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel
- European Standard (EN 10025):
- EN 10025-2: Hot rolled products of structural steels – Part 2: Technical delivery conditions for non-alloy structural steels
- EN 10034: Structural steel I and H sections – Tolerances on shape and dimensions
- Japanese Standard (JIS G3192):
- JIS G3192: Dimensions, mass, and permissible variations of hot-rolled steel sections
- Chinese Standard (GB/T 11263):
- GB/T 11263: Hot-rolled H and cut T section steel
These international standards provide specifications for various properties of H-beams, including dimensions, mechanical properties, h beam for sale chemical composition, tolerances, and testing requirements. Here are some of the typical specifications covered by these standards:
- Dimensions: Specifications for H-beam dimensions typically include the height (H), width (B), flange thickness (tf), web thickness (tw), and flange slope (α).
- Mechanical Properties: Standards specify minimum yield strength, tensile strength, and elongation requirements for H-beams to ensure adequate structural performance.
- Chemical Composition: Specifications outline the chemical composition limits for elements such as carbon, manganese, phosphorus, sulfur, silicon, and trace elements.
- Tolerances: Standards provide tolerances for dimensions, straightness, twist, camber, and mass to ensure consistency and quality in manufacturing.
- Testing Requirements: Standards may include requirements for mechanical testing, such as tensile testing, impact testing, and bend testing, as well as non-destructive testing methods like ultrasonic testing or visual inspection.
It’s important to refer to the specific standard applicable to the project or region to obtain the detailed specifications and requirements for H-beams. Compliance with these standards ensures that H-beams meet the necessary performance, safety, and quality criteria for structural applications.
