3. Chains are made with the use of butt-seam contact welding. Chains are made in sections of 2 m, 3 m, 5 m, 10 m long, without thermal treatment. It is possible to manufacture chains of any length (chains of gage below 6 mm - not more than 53 m long, over 6 mm – not more than 27 m long). 

4. Chains are tied up into bundles with the use of wire. 

5. Chains are shipped without packing; however, they can be packed into polypropylene bags. 

6. Chains are transported by any carriers, in the covered cars securing protection from mechanical damage and ingress of moisture, and subject to due observance of freight regulations valid for the relevant transport facilities.
