Dear Euric and All, What you say is true, but I believe that the savings are greater if you use a 600�mm module.
It's an interesting point that the way the industry has developed in construction sheeting materials is to use a 'standard' sheet of 2400�mm by 1200�mm and this implies a module of 1200�mm.
