1. The open barrel has excellent mechanical properties and high strength, so the steel barrel container can be made into a packaging container with thin wall, high compressive strength and not easy to be damaged. In this way, the safety of the packaged product has a reliable guarantee, and it is convenient for storage, transportation, loading and unloading and use.
2. The processing performance of the open barrel is excellent, the processing technology is mature, and it can be produced continuously and automatically. Steel drums have good ductility and strength, and can be rolled into sheets and foils of various thicknesses. The sheets can be punched, rolled, stretched, and welded to form packaging containers of different shapes and sizes.
