Hi all. I am a complete beginner. I have just bought a Mig welder and need to buy sheet steel. However, I have no idea where I should buy and how much I should be paying. I've looked on eBay and the sheets on sale in my eyes seem expensive for small sizes. Plus it seems that the max size is 1000x500mm. Is it possible to buy a large sheet of say 2500x1500mm? Roughly how much should I pay per M2 of sheet?
