8.2. Products 1: hot-rolled sections

I-sections

Fig. 8.2 IPE and INP sections

Table 8.2 Dimensions of I-sections.

Type	Size	\(h\) (mm)	\(b\) (mm)	\(M_{y;el;d}\) S235 (kNm)	\(M_{y;el;d}\) S355 (kNm)
IPE	80 - 600	80 - 600	42 - 300	4,56 - 1076	6,89 - 1627
INP	80 - 750	80 - 750	46 - 263	4,71 - 1467	7,71 - 2216

Applications: Light structures in residential and non-residential buildings. Used a lot in industrial buildings. It is also possible to use the I sections to make castellated beams 1.

H-sections

Fig. 8.3 HE-A, HE-B,HE-M sections, for each
series the interior dimensions correspond.

Table 8.3 Dimensions of H-sections.

Type	Size	\(h\) (mm)	\(b\) (mm)	\(M_{z;el;d}\) S235 (kNm)	\(M_{z;el;d}\) S355 (kNm)
HE A	100 - 1000	96 - 990	100 - 300	17,1 - 2629	25,8 - 3972
HE B	100 - 1000	100 - 1000	100 - 300	21,1 - 3030	31,9 – 4578
HE M	100 - 1000	120 – 1008	106 - 302	44,8 - 3368	67,6 – 5088

Applications: H-sections are useful for compression elements (columns) or beams where the structural height has to be limited. The increase in section modulus is achieved by using thicker flanges. Due to their large width the H-sections retain their shape relatively well 1.

U-sections

Fig. 8.4 UAP and UNP sections

Table 8.4 Dimensions of U-sections.

Type	Size	\(h\) (mm)	\(b\) (mm)	\(M_{z;el;d}\) S235 (kNm)	\(M_{z;el;d}\) S355 (kNm)
UAP	80 - 400	80 - 400	45 - 100	6,29 - 128	9,51 - 193
UNP	80 - 400	80 - 400	45 - 100	6,22 - 239	9,4 - 361

Applications: Floor edges and landings. Connections between UNP-sections can be complicated due to the inclined edges.U-profiles are not symmetrical, causing the sections to bend along both axes when loaded vertically 1.

Hollow sections

Fig. 8.5 CHS (circular hollow section) and
RHS (rectangular hollow section)

Table 8.5 Dimensions of hollow sections.

Type	Size	\(h\) (mm)	\(t\) (mm)
CHS	42,4 - 610	42,4 - 610	2,6 - 30
RHS	40 - 400	40 - 400	3 - 16

Application: (3D)trusses, columns.

Sheet piling

Fig. 8.6 Different sheet piling sections (U and Z sections)

Applications: Basement walls, foundations, and hydraulic engineering. Sheet piles are available in different sizes and lengths. Sheet piles are used as walls in building pits and structres below ground level. Vertical loads can also be taken 1.
