At its heart, a is a digital document, typically in Portable Document Format (PDF), that contains systematic and standardized data on steel profiles used in construction. These documents are the go-to reference for anyone who needs to look up dimensions, weights, static values, and load-bearing capacities of steel beams, columns, hollow sections, and other structural elements.

: An older standard featuring inclined internal flange surfaces (typically a 14% slope). It is less common in modern construction but widely found in historical structures and specific crane-rail applications. Channels and Angles (U and L Cross-Sections)

There, on the page for U-Profiles (U-Channels) , was a margin note. It wasn't a printed number. It was a pencil sketch, light and frantic.

Plastisches Widerstandsmoment (Tragfähigkeitsnachweis nach EC3)

When downloading or referencing a steel profile PDF data sheet, engineers analyze specific cross-sectional metrics to run statutory load calculations. Property Symbol Description Engineering Application Total Profile Height Determines vertical clearance and depth efficiency. Flange Width Affects lateral torsional buckling resistance. Web / Flange Thickness Protects against local web crippling and flange buckling. Cross-Sectional Area

When downloading a "Stahlliste" or "Profiltabelle" PDF, focus on these critical values: Dimensions (Maße): ), width ( ), and wall thickness ( Weight (Gewicht): Typically listed as for freight and cost calculation. Moment of Inertia ( cap I sub x cap I sub y

Look for charts specifying the maximum allowable bolt sizes ( ) and gauge lines ( ) for flange connections. Digital Alternatives

These tables list dimensions and weights, with sizes ranging from IPE 80 (80 mm height) to IPE 500 (500 mm height). Crucially, they also include values for the cross-sectional area (A), the height of the web (hi), and surface area per meter.

: Standard normal section offering a balanced ratio between weight and load-bearing capacity.

H-Profile mit breiten Flanschen. HEA ist leichter, HEB ist schwerer und tragfähiger.
