The difference between HEA120 beam and HEB120 beam steel
HEA120 h type beam and HEB120 h type steel beam are both hot rolled H-beams of European standard, where the number "120" represents that the height of the H-beam is approximately 120mm.
Flange width
The HEA series is a narrow flange H-beam, and the flange of HEA120 is relatively narrow.
The HEB series is a mid-flange H-beam, and the flange of HEB120 is wider than that of HEA120.
Web thickness: Generally, the web thickness of HEB120 is thicker than that of HEA120.
Cross-sectional area and weight: Since the flange of HEB120 is wider and the web is thicker, its cross-sectional area is larger and the weight per unit length is heavier.
Mechanical properties
Bending capacity: HEB120 h-shaped iron beam has wider flanges and thicker webs. When subjected to bending loads, its ability to resist bending deformation is stronger than that of HEA120 h-shaped steel, and it can withstand greater bending moments.
Torsion resistance: The wider flanges and reasonable cross-sectional shape make HEB120 h-section steel better than HEA120 h-shaped steel beam in torsion resistance, and it is more suitable for use in structures with torsion.
Application scenarios
HEA120 h-shaped beam: It is suitable for general building structures that have certain requirements on structural weight and not particularly high requirements on bearing capacity, such as secondary beams of small buildings, secondary components in light steel structures, etc. Because of its relatively light weight, it can reduce the burden on the foundation when used in some structures that are sensitive to self-weight.
HEB120 h-section steel beams: It is often used in important structural parts that require high bearing capacity and structural stability, such as the main beams of large industrial buildings and the frame beams of high-rise buildings. It can withstand greater loads and complex stress states.
