Radius tolerance chart
WebBending/rolling steel is the process of curving a steel member to a specified radius and arc length. Bending is commonly used to describe the process for a tighter radius bend, whereas rolling is used to describe a larger radius bend. (For more on the bending process, see the Modern Steel Construction article There's More than One Way to Bend a ... WebAug 8, 2016 · Table 3.
