Can someone give me a rough idea how much 65m of 1" box would be.

Cheers Paul

Just a rough price will do.
Not looking at a exact price as I know different places charge different rates.

£100

I last paid something like £1.79/m

Parkersteel

Shop4Steel

Try these.

Although your local steel stockholders should be cheaper.

last time i bought some...about 6months ago.

£7 + vat for 6/7mtr length

Just brought a load from K Steels and it was £6.00 per 6 metres for 25mmx25mm 16swg

thats were mine come from

cheers guys .....
