ETP Coil Specification
-
TMBP is manufactured with a controlled and smooth surface finish to ensure strong adhesion of the tin coating. Additional cleaning, degreasing, and surface treatment processes are applied to remove impurities and enhance coating bonding performance.
-
The tin coating applied to the base steel is measured by coating mass per unit area, expressed in grams per square meter (g/m²) or pounds per base box (lb/base box).
Coating thickness varies depending on the end-use application and required corrosion protection level.
-
TMBP is supplied in different temper grades based on forming requirements. Common temper conditions include:
Annealed (Fully Soft)
Quarter Hard
Half Hard
Full Hard
The temper level determines the material’s strength, hardness, and formability during packaging production.
-
Surface quality specifications ensure the material is free from defects such as:
Scratches
Pits
Rust
Surface contamination
Strict inspection processes maintain uniform quality and proper performance during tin plating and fabrication.
-
TMBP production may comply with international standards such as:
ASTM (American Standards)
JIS (Japanese Industrial Standards)
Other regional packaging standards
Compliance ensures dimensional accuracy, mechanical consistency, and coating reliability.
TMBP Sheet Trade Information
Engineered Base for Tin Coating
TMBP is a cold-rolled steel substrate specifically designed for electrolytic tin plating. It serves as the foundational material for producing tinplate used in metal packaging applications.
Advanced Manufacturing Process
Produced through cold rolling, annealing, and surface preparation, TMBP ensures controlled thickness, improved surface quality, and strong compatibility with tin coating processes.
Superior Formability & Surface Quality
The material offers excellent ductility and smooth surface characteristics, enabling deep drawing, stamping, cutting, and bending without compromising structural integrity.
Wide Packaging Applications
Widely used as the base material for food cans, beverage containers, aerosol packaging, chemical storage cans, and industrial metal packaging solutions.
