INP beams have different sections which are mentioned below:
INP 80, INP 100, INP 120, INP 140, INP 160, INP 180, INP 200, INP 220, INP 240, INP 260, INP 280, INP 300, INP 320, INP 340, INP 360, INP 400, INP 450 , INP 500, INP 550,
The dimensions and size of the INP beam depend on its type. These dimensions are:
| Wing height | Is denoted by the letter h |
| Thickness | Is denoted by the letter ts |
| Wing width | Is denoted by the letter b |
| Wing thickness | Is denoted by the letter tg |
| Cross section | Is denoted by the letter A |
| Weight per meter | Is denoted by the letter G |
For example, the dimensions of the INP 120 beam are equal to:
h = 120mm / ts = 5.1mm / b = 58mm / tg = 7.7mm / A = 14.2cm2 / G = 11.1 kg / m
INP beams are widely used in various industries such as construction, bridge construction, pier construction, dam construction, tower construction and similar industries.
