Product Characteristics

Tin mill products are produced with certain standardized product characteristics, including terminology, composition, mechanical properties, surface finish, coating weights and the like. These characteristics are covered in detail in the ASTM Standard Specifications list under references. We have summarized the most pertinent.

Classification of Tin Mill Products
