Machines are often categorized by the type of rib pattern they produce and their technical specifications.
Rib Pattern: Machines can typically produce either 2-rib or 3-rib rebar. 3-rib machines are often used for higher-strength grades like CRB600, as the increased rib density provides better bonding
Key Parameters: According to specifications from various manufacturers, modern machines can process wire rod with input diameters of 5.5-14mm, producing final wire diameters of 3.5-12mm at speeds ranging from 3 to 12 meters per second. Some fully automated lines can produce compact coils weighing 2 to 8 tons
Process Variants: While most machines use a "drawing" or "active-passive" rolling process (where one set of powered rolls pulls the wire through another set of unpowered rolls), there are also high-performance systems that combine cold stretching with respooling, suitable for larger diameters up to 20mm.
