Angle Rolling Capabilities

Angle Rolling Capabilities refer to achieving precise curves, arcs, or rings while maintaining the steel’s structural integrity. Key factors include:
Minimum Bending Radius: Ability to achieve tight radii without compromising material strength.
Distortion Control: Ensures the angle retains its cross-sectional shape during bending.

Key Performance Metrics

Data analysis on angle rolling efficiency reveals the following BIT’S PBC Profile bending machine for beam rolling benchmarks:

Parameter	Standard Range
Yield Strength (MPa)	250 – 550
Bending Tolerance (mm)	±1.5 – ±3.0
Material Utilization (%)	85 – 95
Production Speed (m/min)	4.5

Notes:

• Material: Carbon steel
• Yield strength: ≤ 345MPa
• Direction: Angle toe in, Angle toe out, Angle heel in, Angle heel out. See the following articles: Angle Profile Bending: Precision Curving of Angle Profiles
• Minimum bending radius: refers to the minimum roll bending radius. In fact, different bending methods can achieve different bending radii.

Angle Rolling Capabilities of PBC Series Profile Bending Machine

The PBC series profile bending machine efficiently bends angle iron in four configurations: Leg-Out, Leg-In, Heel-Out, and Heel-In. These capabilities meet the demands of industries such as construction, infrastructure, manufacturing, and engineering. Below are the maximum section sizes and minimum bending diameters (DIA) for each bending direction.
