Cold-Drawn Steel Bar
Cold drawing hot rolled bars is accomplished by pulling (drawing) a bar through a die which is smaller than the incoming hot rolled size. The “cold working” process improves the dimensional tolerances of the bar, the straightness, and the surface appearance and enhances the physical properties of the steel.

Equivalent Material
Transport packaging is used to minimize product damage during transportation and distribution, ensure product safety, facilitate storage, transport, loading and unloading, and expedite handover and inspection. People utilize packaging for transportation, storage, and handling. Also known as outer packaging, its main function is to protect goods, prevent damage during storage and transportation, minimize the impact of various external conditions on the goods during transport, and facilitate inspection, inventory, and distribution.
Transport packaging should meet the following basic requirements:
• Sufficient strength, rigidity, and stability;
• Waterproof, moisture-proof, insect-proof, corrosion-proof, and theft-proof capabilities;
• The selection of packaging materials should meet economic and safety requirements;
• The weight, dimensions, markings, and form of the packaging should conform to international and national standards, facilitating handling and loading/unloading;
• Reduce the labor intensity of workers and ensure safe and convenient operation.
The basic principles that should be followed in the design of transport packaging equipment include: standardization and serialization; containerization and large-scale principles; diversification and specialization principles; scientific principles; and ecological principles.
