metal frame

[Chrispy91]

i just need to know what type of metal i should use for my frame. im buying from metal supermarkets because its close by and they have aluminum, hot rolled structural, and cold rolled crew. all i need to know is which one i should use

Cold rolled is fine, thin wall (16ga or 1.6mm) is thick enough, the type/size of the frame will determine the OD
