HEB steel follows strict European norms (EN 10034), with dimensions defined by height (h), flange width (b), web thickness (tw), and flange thickness (tf). The naming convention-e.g., HEB 100, HEB 200-indicates the approximate height in millimeters, with proportional increases in other dimensions:
HEB 100: h=100mm, b=100mm, tw=6mm, tf=10mm (ideal for light loads)
HEB 300: h=300mm, b=300mm, tw=9.5mm, tf=16mm (suitable for medium - span structures)
HEB 600: h=600mm, b=300mm, tw=13mm, tf=21mm (designed for heavy - duty applications)
These standardized dimensions ensure universal compatibility: components from different manufacturers fit seamlessly, reducing design complexity and on - site adjustments. For example, a HEB 200 beam can be directly bolted to a HEB 200 column using pre - engineered connection plates, saving 15–20% of construction time compared to non - standardized profiles. The symmetrical H - shape also balances load distribution in both x and y axes, making it ideal for structures requiring bidirectional strength, such as building frames and bridge girders.
