P Shape 40X60mm Pallet Rack Step Beam Roll Forming and Welding Machine 

Description

P Shape 40X60mm Pallet Rack Step Beam Roll Forming and Welding Machine

The Pallet Rack Step Beam Roll Forming Line is primarily designed for the mass production of step beams through an automated process that includes on-line welding. It can continuously weld every 20-30cm. The entire roll-forming line consists of several components including a decoiler,  a roll forming machine, a hydraulic shearer an in-line arc welder, a straightening unit, a run-out table, and an electrical control panel, among others.
