With the further deepening of China's opening to the outside world, national standard steel drums have been restricted in export packaging. In recent years, many steel drum enterprises in China have begun to improve the international generalization of products. Among them, the rapid development is ISO international standard steel drums, container-specific steel drums and conical opening steel drums. The steel drum closure has been fully realized international generalization.

ISO international standard steel drums are mostly used for exporting chemical product packaging. With a standard diameter of 571mm and a capacity of 42 gallons, this is the steel drum product with the most development potential in China.

Steel drums for containers, often called W-reinforced steel drums in the industry, are improved by combining national standards and Italian standards, and are transition products between national standard steel drums and international standard steel drums. The maximum diameter of the ring bars of this steel drum is smaller than that of the national standard steel drum, which not only saves the space occupied by the steel drum in container transportation, but also strengthens the strength of the steel drum.

Conical open steel drums are completely produced according to Italian standards and are mostly used for the packaging of food raw materials. At present, they have been widely used in western China, mainly for export packaging of ketchup and jam. The main features of this steel drum are that the transportation cost of empty drums is low, it is easy to recycle and dispose of, and it takes up more space in container transportation.

The structure and size of the closure of the closed steel drum have completely adopted the international standard inch closure, which has completely realized the transition of international generalization.
