LMS Heavy Duty Upright Roll Forming Machine

The Heavy Duty Upright Roll Forming Machine is designed for the efficient production of high-strength upright profiles used in heavy duty racking systems, mezzanine floors, and industrial steel structures. The machine continuously forms steel coils into precise and consistent upright sections, meeting strict requirements for load capacity, dimensional accuracy, and structural stability.

Built with a heavy-duty machine frame and multiple roll forming stations, this equipment is capable of processing thick materials such as hot-rolled steel, cold-rolled steel, and galvanized steel. The optimized roll forming process ensures uniform stress distribution, excellent straightness, and smooth surface quality of the finished uprights.

According to production requirements, the machine can be equipped with automatic decoiler, leveling system, in-line punching unit, and servo flying cut-off system to achieve a fully automated production line. The PLC control system with touch screen allows easy parameter setting, stable operation, and efficient production management, significantly reducing labor costs while improving output efficiency.

With reliable performance, flexible customization options, and consistent product quality, the Heavy Duty Upright Roll Forming Machine is an ideal solution for manufacturers seeking to enhance productivity and competitiveness in the heavy duty racking and steel structure industry.
