Section Bender

The section bender is a kind of high-efficiency processing equipment dedicatedly used for bending various special sections, such as the angle steel, U steel, I steel, flat steel, square steel, round steel, etc. It enables one-time material loading, rolling and calibrating, widely applied to the petroleum, chemical engineering, hydroelectricity, shipbuilding, the machinery manufacturing and other industries.

Two lower rollers of this section bender are used for driving. Or, three rollers can be used as the main driving rollers. Two side rollers are in arc lifting motion around the fixed gyration center. As there is no roller carrier on both sides, the rolling quality of asymmetrical sections is perfectly guaranteed.
