Where do you guys get the raw material from? I am thinking about buying from a trash disposal service like link removed would that be a good idea in your opinion? Thought about buying it from a store at first but having done some calculations, I concluded that it would simply ruin my business, given their prices. I don't think there is a vast difference between the quality of recycled metal and the new one, plus, you are eco-friendly, reusing the same material.
