Frequently Asked Questions (FAQ)
Tinplate Coil, also known as Electrolytic Tinplate (ETP or SPTE), is a cold-rolled, low-carbon steel coil uniformly coated on both sides with a high-purity tin layer through advanced electroplating technology. It combines the mechanical strength of steel with excellent corrosion resistance, superior solderability, and an attractive surface finish, making it ideal for food packaging, beverage cans, and industrial containers.
Tinplate Coils are produced in a range of temper grades, including T1, T2, T2.5, T3, T4, T5, DR7, DR8, DR9, DR9M, and DR10. These grades correspond to different hardness and strength levels, tailored to specific forming, deep drawing, and stamping requirements in packaging and closure applications.
Standard tin coating weights range from 1.1/1.1 g/m² up to 8.4/8.4 g/m², including differential coatings such as 2.8/5.6 g/m² or 5.6/8.4 g/m². Thickness options typically span from 0.12 mm to 0.60 mm, customizable to meet diverse industrial and packaging needs.
The price of Tinplate Coils varies based on multiple factors, including steel base grade, tin coating weight, temper grade, coil dimensions, order volume, and delivery terms. Typical FOB prices range between US$750 to US$780 per metric ton for standard MR or SPCC base steel with medium tin coating weights (e.g., 2.8/2.8 g/m²) and temper grades from T2 to T4. For precise quotations, contact Hengze Steel’s sales team.
