someone save me the maths. how much metal do I order

[jason 82]

Hi, I ordered about 37 meters I think it was. But I did not buy the erw as the book suggests, it's much cheaper to buy normal 25mm box section, I asked for a 2mm wall, so that it was a little harder to burn through than the 1.6mm. My box section came in 7.5meter lengths, and cost £54 including vat. If I wanted erw, it was almost £150.

ok sooo 37 meters of 25mm box. what does erw stand for? 2mm or 1.6mm ill look at wieght differance later but 2 is prob safer with 200ish bhp

what other metal is needed. want to get it all to have some bargining power if u catch my drift.

Hi Nick.

ERW = electrically resistant welded CDS = cold drawn steel / seamless.
