Coiled plate: Weighing weight ÷ parameter thickness (actual thickness) x theoretical thickness = theoretical weight
Coiled plate and flat plate: length x width x thickness x density = theoretical weight
Medium plate: length x width x theoretical thickness x density = theoretical weight
Roll length: actual weight ÷ width ÷ thickness (reference thickness) ÷ density = roll length
The actual thickness of the roll: trimmed roll = roll weight ÷ width ÷ roll length ÷ density
Raw edge roll = (roll weight and wire weight on one side) ÷ width ÷ roll length ÷ density
Flat price: flat price = (roll weight * market base price and wire amount on one side + opening and leveling fee) / total weight of the flat plate
