Which machine cuts rebar 40 mm and above?
Quick answer: for 40 mm and heavier rebar you have two options: the GDQX-500 shear line cuts 10–40 mm in batch (including 4 bars of Ø40 per stroke in HRB400), while the GQ70A single cutter goes up to 70 mm in A3 steel and 55 mm in Grade II.
Above 40 mm: once you pass 40 mm you are into heavy structural steel, and the GQ70A is the machine — 70 mm A3, 55 mm Grade II, 50 mm Grade III, 45 mm Grade IV, with a shearing force under 160 t on an 11 kW motor.
How to choose: if you cut 40 mm bars by the ton every day, the shear line is faster; if you occasionally cut a few 50–70 mm bars, the single cutter is the economical choice. Cutting capacity is always quoted for A3 mild steel, so derate for ribbed grades.
