The SweBend SB4 Four Roll Section Bending Machine Series starts with the SB4B-55 and ranges up to the SB4-240S. The machines are extremely sturdy in design and have more power compared to any other section bending machine on the market.

Number of rolls – 4-rolls
Operation – hydraulic
Sheet thickness: Min: 2mm / Max: 200mm
Sheet size: Min: 1000mm / Max: 12000mm
Type ‘B’ is the basic model without guide rolls
Type ‘S” is with fully hydraulic guide rolls, allowing users to bend and compensate/correct all types of sections
Both types have the same geometry and capacities
