Strut channels are commonly made of galvanized steel with the thickness of 1.5-2.0mm, 2.0-2.5mm or stainless steel with the thickness of 1.5-2.0mm. They are designed with regularly spaced holes or slots along the length of the channel, allowing for easy attachment of bolts, nuts, or other fasteners.

A production line equipped with automatic size changement is suitable for manufacturing demands of two or more sizes, such as common sizes like 41*41, 41*21, 41*52, 41*62, 41*72, 41*82mm. The higher the height of the strut channel, the more forming stations there are, and consequently, the price of the roll forming machine will increase accordingly.

Hydraulic decoiler with leveler

This type of decoiler is also known as a "2in1 decoiler and leveler". Its compact design can save up to approximately 3 meters of production line space, reducing factory land costs for our clients. Furthermore, the reduced distance between the decoiler and leveler minimizes setup difficulties, making coil feeding and operation more convenient.

Servo Feeder & Punch Press

The servo motor operates with virtually no start-stop time delay, allowing precise control of the coil's feed length for accurate punching. Internally, pneumatic feeding in the feeder effectively protects the coil surface from abrasion.

Typically, the hole spacing of the strut channel is 50mm, with a punching pitch of 300mm. Compared to hydraulic punch machines of equivalent punching force, the punch press achieves a faster punching rate of approximately 70 times per minute.

While initial investment costs for punch presses might be higher than hydraulic punches, they can provide better long-term cost-effectiveness, especially for high-volume production. Additionally, maintenance costs for punch presses might be lower due to simpler mechanical components.

We have chosen Yangli brand punch press from China as our primary and long-term selection because Yangli has multiple offices worldwide, providing timely after-sales support and service to our clients.

Guiding

Guiding rollers ensure that the coil and the machine are aligned along the same centerline, guaranteeing that the coil remains undistorted during the forming process.

Roll forming machine

This forming machine utilizes a cast-iron structure and gearbox driving system. The steel coil will pass through a total of 28 forming stations, undergoing deformation until it matches the drawings.

After workers set the dimensions on the PLC control panel, the forming stations of the roll forming machine will automatically adjust to the correct positions, with the forming point moving along with the movement of the rollers.

For safety during the movement of forming stations, two distance sensors are placed on both the left and right sides, corresponding to the outermost and innermost positions that the forming stations can be moved to. The sensors detect the base of the forming stations. The innermost sensor prevents the forming stations from getting too close and causing roller collisions, while the outermost sensor prevents the forming station from disengaging from the rails and falling.

The surface of the forming rollers is chrome-plated to protect it and extend the rollers' lifespan.

Flying hydraulic cut

The base of the cutting machine can move back and forth on the track, allowing the steel coil to continuously advance through the roll forming machine. The roll forming machine doesn’t need to stop, thus increasing the overall speed of the production line.

The cutting blade molds match the shape of the corresponding profiles. Therefore, each size requires an independent set of cutting blade molds.

1. Q: What kinds of experience do you have in producing solar photovoltaic stents roll forming machine?

A: We have experience of exporting our solar photovoltaic stents roll formers to Saudi Arabia, Turkey, Iraq, India, Kuwait, Qatar, Pakistan, Argentina etc. We have produced solid channels, slotted channels, punched channels, standard channels, American standard racks etc. We are confident to solve your solar racking problem.

2. Q: How many sizes can be made in one machine?

A: One machine could produce one same width with different heights like 41x21, 41x41, 41x62, 41x82 or 27x18, 27x30.

3. Q: What is delivery time of solar photovoltaic stents roll forming machine?

A: 80 days to 100 days depends on your drawing.

4. Q: What is your machine speed?

A: Machine’s working speed depends on drawing specially punch drawing. Normally forming speed is around 20m/min. if you want a higher speed like 40m/min, we give you a solution with rotary punch system, which punch speed is up to 50m/min.

5. Q: How could you control your machine’s precision and quality?

A: Our secret to producing such precision is that our factory has its own production line, from punching moulds to forming rollers, each mechanical part is completed independently by our factory self. We strictly control the accuracy at each step from design, processing, assembling to quality control, we refuse to cut corners.

6. Q: What is your after-sales service system?

A: We don’t hesitate to give you a two-years warranty period for whole lines, five years for motor: If there will be any quality problems caused by non-human factors, we will handle it immediately for you and we will be ready for you 7X24H. One purchase, lifetime care for you.
