Standard adjustable square column clamps are sold and measured by per set(4 flat steel pieces+wedge pins),with weight determined by adjustable column size,steel grade(Q235/Q345B)and clamp width.For general construction standard models:
Small light-duty(adjust range 200–400 mm):7–8 kg/set
Medium standard(400–600 mm,80 mm width):18–21.6 kg/set
Medium-large(500–800 mm,80 mm width):20.5–26.2 kg/set
Heavy-duty large-size(700–1000 mm,100 mm width):36.5–51 kg/set
Extra-large(900–1400 mm):57.2–65 kg/set
Weight deviations are within±0.5 kg due to manufacturing tolerance;galvanized surface treatment adds a small weight increment.
