110 pipe through a steel

I know this is probably a very stupid question but I'd rather ask. Is there any way a drainage pipe could go through the vertical part of a steel? I have a 3m 203x133x30UB steel that's in the way of a pipe run idea, that would get rid of a pipe in the corner of the dining room and move it to inside the W.C. It's not the end of the world if there's no way but I wondered if the steel could be beefed up to do it? Vijay

I wonder if you could weld plates either side, themselves with 110mm holes in connecting the flanges? Thus replacing the "strength" you've taken out of the web... I've considered doing exactly what you're proposing to give me a soil run down the centre of the house. This for upstairs wcs and showers in all the bedrooms. I've an RSJ "in the way" that runs under the centre of the dormer.
