APPLICATION
Equipment for cold rolling of steel strips into structural profile (Light steel thin-walled structures). The metal profile is used for the construction of frames of prefabricated buildings.
The roll forming machine is used for the production of:
- C, Z-profile (width 100-240mm)
- Σ-profile (width 50-130mm)
- Guide profile for drywall (0.5-0.6 mm)
The metal profile is made of strips of the required thickness. The profile geometry, along with the thickness and grade of steel, determines the load-bearing capacity of the structure.
C, Z, and Σ (sigma) steel profiles are used as columns and spans of walls and roofs of prefabricated buildings. The guide profile is used for the installation of drywall and structures for interior decoration.
The processed material is a steel strip or galvanized steel. The strip thickness is 0.5-4.0mm, the width is 50 to 240mm. Length of finished products is up to 12 m
FEATURES
The machine control system is fully automated and minimizes the human factor influence. The roll forming machine is controlled by a computer via a touch-screen graphical interface.
The tachometer monitors the unwound steel length and counts the produced profile length.
The shafts and passline rolls of the machine are manufactured on CNC machines with high precision.
Metal parts are made of structural steel with a chrome coating 0.05mm. The material of the shafts and rollers is wear and rust resistant. The guillotine blade is made of hardened steel and has a long service life.
The frame of the roll forming machine is annealed to prevent stresses and deformations during operation.
All roll forming machines are pre-tested before shipment. The equipment is guaranteed for 12 months.
We perform commissioning and provide technical support throughout the entire service life.
STRUCTURE AND OPERATION
The equipment pulls the steel strip from the roll and feeds it to the roll forming machine. The machine is a bending matrix equipped with rows of rollers on shafts driven by chain transmission.
The strip is profiled as a result of bending, where the strip is simultaneously exposed to compressive and tensile forces. Rows of rollers gradually form the strip into the desired profile, pressing the metal to the matrix.

At the machine exit, the profiled sheet is cut off with hydraulic shears and fed to the output roller conveyor.
The rolling machine, electric and hydraulic drives, and chain transmission are assembled on a single frame. The uncoiler is a separate machine equipped with a sheet speed sensor.
