4. Material

Standard product range:

Flanges:	Wide flat steel or steel lamellas S235JRG2 in accordance with EN 10 025 (RSt 37.2 in accordance with DIN 17 100)
Web:	Cold rolled sheet St 37-2G in accordance with DIN 1623, Part 2 with a guaranteed yield strength RH,min = 215 N/mmÓ

Special qualities:

For the purposes of material purchasing, all other qualities of steel are regarded as special qualities.

The use of higher strength material (S355J2G3 = St52.3 N) for the flanges is possible, but in terms of statics, this is only meaningful in exceptional cases. Similarly, web material of higher yield strength up to 320 N/mmÓ (StE 320) can also be processed for the web. However, for reasons of material purchasing, longer delivery times and appropriate minimum order conditions apply.
