Rebar Bender Machine Guide: GW40 / GW45 / GW50
Rebar benders bend steel bars into the shapes needed for concrete reinforcement; the right model depends on bar diameter, volume and whether you need automatic or manual operation.
What rebar benders do
Rebar benders bend steel reinforcing bars to angles for foundations, beams and columns. They are rated by the maximum bar diameter they can bend, typically 40mm, 45mm or 50mm.
GW40 vs GW45 vs GW50
- GW40: bends up to 40mm bar, the standard choice for most sites
- GW45: handles up to 45mm, a step up for heavier work
- GW50: up to 50mm for large infrastructure projects
Automatic vs manual
Automatic rebar benders set the angle digitally and run repeat bends quickly, which saves labor on high-volume jobs. Manual benders cost less and suit occasional work.
Choosing for your volume
For a fabrication shop with daily output, an automatic model pays for itself. For small or occasional jobs, a manual bender keeps the investment low. See the full machinery range for options.
