Strut Channel Roll Forming Machine Making Unit-strut Channels

Briefly, a Uni Strut Channel roll forming machine produces the steel channels, which usually supports wiring, plumbing, or mechanical components, such as air conditioning and ventilation systems.

“Strut channel is a standardized formed structural system used in the construction and electrical industries for light structural support”. According to WIKI, Strut is usually formed from metal sheet, folded over into an open channel shape with inwards-curving lips to provide additional stiffness and as a location to mount interconnecting components. Increasingly, strut is being constructed from fiberglass, a highly corrosion-resistant material that’s known for its lightweight strength and rigidity. Strut usually has holes of some sort in the base, to facilitate interconnection or fastening strut to underlying building structures.“

Basic strut channel comes in the open box section, where several variations are available with small different shapes as well as different hole patterns for mounting to walls and supports. Generally, the materials for making the channels are 1.5-2.5mm thick zin-coating steel or cold rolled steel. In addition, some other materials are also available for different applications. For instance, stainless steel will be used where rusting might become a problem (e.g., outdoors, facilities with corrosive materials), while aluminium alloy is better material when weight is an issue or from fiberglass for very corrosive environments. A roll forming equipment that manufactures strut channels is strut channel roll forming machine.

Brief Introduction of uni strut channel roll forming machine.

A strut channel roll forming machine is the equipment that manufactures strut from galvanized steel of 1.5-2.5mm thickness. In addition, one strut channel roll forming machine can technically produce 3 profiles by adjusting different spacers between rolling tools.

As a matter of fact, the key parts in the line are punching unit, roll forming unit and cutting unit. However, the position and working method for punching and cutting unit may vary.

There are two solutions to roll form strut channels, based on the line speed:

Economical Solution:

By this solution, clients can save much money and working areas, however, it’s working at a max speed only 3m/min. The whole line includes uncoiling, leveling, roll forming, hydraulic punching, hydraulic cutter, runout tables and PLC control system. Manufacturers use post hydralic punching unit integrated on roll former. The roll forming machine stops to run when hydraulic punching and hydraulic cutting work.

Automatic Solution:

The line works with an auto feeding unit, high-speed pressing machine and tracking cutter in order to run continuously without stopping. As a result, this strut channel roll forming machine can reach max. speed 30m/min. The whole line consistss uncoiling, leveling, auto feeding unit, high speed pressing unit, roll forming, hydraulic tracking cutter, auto stacker and PLC control system. As you may notice, an individual high-speed pressing stays between an individual levelling unit and roll forming unit.

“You’ve made such a great roll forming equipment that helps me complete my projects so much faster and easier. ”

We make things easy for projects.

Roll forming machine usually is always our first choice as long as we need to produce metal sheet or steel section products. A roll forming machine can do automatic jobs of bending, cutting, pressing for holes and slots, and straightening etc.

Roll forming machines have so many advantages over press brake and shearing machines! With rollforming equipment, we can save much more time, working area, money as well as labors.

There are numourous applications where we need a roll forming machine. For example, we need roll forming machines to produce metal roofing and wall/siding. We must use decking roll forming machines to produce metal or steel decking for roofing and floor. Guardrail roll forming machines are used for producing crash barriers or guard rails on highway construction. Besides, we can find in the markets c/z steel purlin roll forming machines, top hat purlin roll formers; stud and track roll former for light weight steel buildings; down pipe roll forming machines and roll forming machines for door products etc.
