European Standard Beams – IPN



IPN

IPN is the short form for bar shaped building elements or beams with inclined internal surface of the flanges and dimensions according to DIN 1025.
Their product tolerances are characterized through EN 10024: 1995.
The IPN series has significantly lost importance due to the inclined flanges in favor of the assemble-friendly IPE series.
A stainless steel beam can be or jointed – then it is welded or bolted – or warm manufactured – then it is hot rolled or extruded. Upper and lower horizontal part of the beam is called flange, the connecting vertical middle part is called web.
According to EN 10088-3: 1D the following austenitic grades are predominantly used for stainless steel structurals: 1.4301 (304), 1.4307 (304L) , 1.4401 (316) , 1.4404 (316L) and 1.4571.
