1. There is no difference in the use of rolled plates and flat plates. The leveling of rolled plates is equivalent to flat plates. In terms of price, rolled plates are usually calculated based on actual weight, while flat plates are calculated based on theoretical weight. Therefore, rolled plates are usually slightly thicker than nominal thickness, while flat plates are definitely thinner. Therefore, for the same material, each ton of rolled plates is more expensive than flat plates. In practical applications, using rolled plates instead of flat plates is completely feasible. The standards for original flat plates and flat plates are different, If the main pressure components of a pressure vessel are to be made, a flat plate cannot be used.
2. In terms of price: Roll plates are usually calculated based on actual weight, while flat plates are calculated based on theoretical weight. Therefore, roll plates are usually slightly thicker than nominal thickness, while flat plates are definitely thinner. Therefore, roll plates of the same material are more expensive per ton than flat plates. In practical applications, using roll plates instead of flat plates is completely feasible.
