Solar Panel Mounting Bracket Roll Forming Machine Production Line Standard

Solar Panel Mounting Bracket Roll Forming Machine Production Line

A fully automatic roll forming line that produces solar mounting brackets, rails and strut channels in four pre-stored sizes on one machine, with servo-driven automatic changeover.

• Four sizes in one line: 41x21, 41x41, 41x61 and 41x81 pre-stored in the PLC.
• Servo-driven automatic changeover by one-touch recall, minutes instead of hours, no roller disassembly and no skilled technician needed.
• Forming, punching and cutting in a single pass at 15-20 m/min (49.21-65.62 ft/min).
• 28 roller stations with gearbox transmission, Cr12MoV quenched rollers of 60 mm diameter and a 40 mm moulding frame.
• 3 T hydraulic decoiler with servo feeder, coil inner diameter 450-550 mm.
• 33.5 kW (44.92 hp) installed power, PLC with touch screen, ISO and CE certified, 2 years warranty.

Product Overview

This line turns GI, PPGI, GL or PPGL steel coil into the channel sections used for solar panel mounting: rails, brackets and strut channels for rooftop arrays, ground-mounted farms, carports and agricultural PV sheds. Roll forming, punching and cutting run in a single pass at 15-20 m/min, so the finished bracket comes off the line ready for assembly.

What separates this machine from a standard roll forming line is the changeover. The four profile sizes are stored in the PLC, and the servo motors adjust the rollers and the guides to the stored position automatically. Changing from one size to another is a one-touch recall rather than a manual roller change, which keeps batch dimensions identical and makes multi-spec solar racking orders practical on one line.

Key Features

Four Sizes In One Line

The four Strut Channel sizes 41x21, 41x41, 41x61 and 41x81 are pre-stored in the control system, so the same line covers the size range used across solar mounting systems without additional tooling sets.

Servo-Driven Automatic Changeover

Closed-loop servo control drives the pressure rollers and the guiding system to adjust thickness and width automatically. Profile parameters sit in the PLC as a one-touch recall and the machine completes all adjustments itself, so no roller disassembly or manual calibration is required and changeover takes minutes instead of hours.

Forming, Punching And Cutting In One Pass

Roll forming, punching and cutting are combined in a single pass at 15-20 m/min. The 28 roller stations run on gearbox transmission, which keeps the profile uniform along the length of a large volume production run.

Cr12MoV Quenched Rolls And 40 mm Frame

The forming rollers are Cr12MoV with quenched treatment at 60 mm diameter, which holds the section sharp and consistent. The moulding frame is built with 40 mm thickness plate to absorb vibration during forming, which supports both accuracy and long service life.

3 T Hydraulic Decoiler And Servo Feeder

A 3 ton hydraulic decoiler with a coil inner diameter of 450-550 mm opens the coil actively and tensions it through the hydraulic station, so labour is saved and the coil runs faster. Together with the servo feeder the line runs from coil to finished bracket with minimal operators.

Hydraulic Cutting With Quick-Change Blade Set

The hydraulic cutting unit uses a quick-change blade set, so blade changeover is short and downtime is low. Cutting is smooth and stable and produces clean, burr-free ends for downstream assembly.

PLC And Touchscreen Control

The machine is PLC and touchscreen controlled. All four profile sizes are pre-stored, and to change over the operator touches the screen once and the servo motors move to position. Parameters are digitally stored and reproducible, which keeps quality and efficiency consistent between batches.

One Line For Every PV Project Type

The line produces the solar mounting rails, brackets and strut channels used for rooftop solar, ground-mounted farms, carports and agricultural PV sheds, covering the full range of mounting profiles used on those projects from a single line.

Technical Specifications

Channel Profiles

The section drawing below shows the channel geometry and the slot layout for the punched version. Dimensions on the drawing are in millimetres and include the 41 mm channel width, the 21 mm and 41 mm section heights and the slot dimensions. The four sizes pre-stored in the PLC are 41x21, 41x41, 41x61 and 41x81.

Applications

The channel sections produced on this line are used as the structural members of solar mounting systems:

• Rooftop solar arrays: mounting rails and brackets fixed to pitched and flat roofs.
• Ground-mounted solar farms: rail and bracket profiles for large arrays.
• Solar carports and agricultural PV sheds: channel sections for the structural frames.
• General strut channel: slotted and unslotted channels for supporting and fixing services.

A reliable mounting system keeps the panels securely fixed and helps the array withstand wind, rain and snow loads, which is why the section accuracy and the consistency of the punched slot pattern matter as much as the production speed.

Packing And Supply Scope

• Supply scope: 1 set, sold as a single item.
• Single package size: 1200 x 160 x 150 cm.
• Customization options: packaging and core components, each with a minimum order of 1 set.
• Customization ability: minor, drawing-based, sample-based and full customization.

FAQ

What does this machine produce?

Solar mounting rails, brackets and strut channels formed and punched from steel coil in one pass, in the four sizes 41x21, 41x41, 41x61 and 41x81.

How does the size changeover work?

The four profile sizes are pre-stored in the PLC. The servo motors drive the rollers and the guiding system to the stored position through closed-loop control, so changeover is a one-touch recall that takes minutes and needs no roller disassembly or skilled technician.

What are the main technical figures?

15-20 m/min production capacity, 28 roller stations with gearbox transmission, Cr12MoV quenched rollers of 60 mm diameter, a 40 mm moulding frame, 33.5 kW (44.92 hp) installed power on 220 V, 380 V or 440 V, and a machine weight of 15000 kg.

How is the correct machine confirmed before production?

Before manufacturing, the panel drawing, material specification, production capacity, voltage and workshop layout are confirmed with the buyer, and a sample profile is verified so that the machine meets the production requirement.

How are our workers trained to run the line?

A professional manual and video tutorials cover machine operation, PLC wiring and basic usage, and after-sales engineers can visit the project site to provide on-site guidance.

What warranty and inspection are provided?

A 2 year warranty with free repairs and replacements within that period, ISO and CE certification, video outgoing-inspection and a machinery test report. Technical support from after-sales engineers is available for the lifetime of the machine.
