Performance Characteristics of the Steel Drum

The application of steel drums has only a history of just over one hundred years, but it has developed rapidly and has a wide variety of types. It is widely used in industrial product packaging, transportation packaging, and sales packaging mainly because steel drums have the following performance characteristics:

• The mechanical performance of steel drums is excellent, with high strength, so steel drum containers can be made into thin-walled, high-pressure-resistant, and not easily damaged packaging containers. This ensures the safety of packaged products and facilitates storage, transportation, handling, and use.

• Steel drums have excellent processing performance and mature processing technology, capable of continuous and automated production. Steel drums have good ductility and strength, and can be rolled into sheets, foils of various thicknesses. The sheets can be stamped, rolled, stretched, and welded to produce packaging containers of different shapes and sizes.
  

• Steel drums have excellent overall protective performance. The water vapor permeability of steel is very low and completely opaque, which effectively avoids the harmful effects of ultraviolet radiation. Its gas barrier properties, moisture resistance, light-shielding properties, and shelf-life greatly exceed those of plastic, paper, and other types of packaging. Therefore, steel drums can maintain the quality of goods for a long time, which is especially important for food packaging.
  

• Steel drums have a special metallic luster and are also easy to print and decorate, making the appearance of products luxurious, beautiful, and marketable.

• Steel drums have abundant resources, low energy consumption and cost. Moreover, they are reusable and recyclable, making them ideal in terms of environmental protection.

Although steel drums have the above characteristics, they also have some shortcomings. The main one is poor chemical stability and lower corrosion resistance compared to plastics and glass, especially ordinary steel is prone to rust. Therefore, steel drums often need to be coated with a layer of rust-proof material on the surface to prevent corrosion and damage from the outside and the packaged goods during the steel drum manufacturing process. At the same time, it is also necessary to prevent harmful substances in the steel from contaminating the goods. For example, steel may contain varying levels of heavy metal ions such as Pb and Sn, which can interact with goods, especially food, causing pollution and posing significant risks to human health.
