HEB (European Hot - Rolled Beam) steel follows the EN 10034 standard, with dimensions defined by height (h), flange width (b), web thickness (tₙ), and flange thickness (tբ). The naming convention uses "HEB" followed by a number indicating the approximate height in millimeters, such as:
HEB 100: h=100mm, b=100mm, tₙ=6mm, tբ=10mm (ideal for light interior structures)
HEB 200: h=200mm, b=200mm, tₙ=8.2mm, tբ=13.5mm (common for medium - span beams)
HEB 300: h=300mm, b=300mm, tₙ=9.5mm, tբ=16mm (suitable for industrial load - bearing frames)
HEB 600: h=600mm, b=300mm, tₙ=13mm, tբ=21mm (designed for heavy - duty bridges and high - rises)
These dimensions ensure compatibility across European and international projects. The symmetrical H - shape balances load distribution in both x and y axes, reducing material waste by 10–15% compared to non - standardized profiles. For example, a HEB 400 beam can be directly connected to a HEB 400 column using pre - engineered end plates, streamlining on - site assembly.
