Hot Rolled Sheet
HRC (or Hot Rolled Commercial steel sheet) is very commonly used for a wide range of general purpose fabrication situations such as trailer floors, fuel tanks etc. Easy to weld and fold. Remember stock items can be purchased in any quantity, even in part-sheets.
Cold Rolled Sheet (CRC)
Cold Rolled Black Sheet (CRC) is much softer and more malleable than HRC. It's perfect for jobs that require the sheet to be shaped a particular way. Ideal for body work on cars, for example!
