Guys, I could do with a bit of help here. I've recently got my plans through for a nice new garage/workshop. The roof needs some 356 x 171 Universal Beams and the door lintle needs a 430 x 100 PFC. Question is, what is a PFC. I've not come across that term before. Also, does anyone know of a steel salvage place that might have these second hand as they're a bit pricey new.
Thanks
John
