Trapezoidal Roll Forming is large sized industrial machine for the continuous bending of a long strip of flat sheet of metals like steel, iron etc. into a desired cross-section. It consist of a number of rollers that are fixed in a proper sequence through which the metallic plate is passed for performing only an incremental part of the bend, until the required profile is obtained. Trapezoidal Roll Forming is capable for producing constant shapes with long lengths and in large quantities. The machinery is installed with an automatic controlling unit to easily operate it by using a single operator.
