Output

What This Machine Produces

01

Omega (Ω) rails — the horizontal member that runs across the roof and carries the panel clamps, spanning between the roof hooks or mounting feet.

02

Hat-section rails — the same stiffening principle with a different fold pattern, giving stiffness in the direction of the roof load while presenting a flat top face for the clamps.

03

Aluminium rails in 6063 or 6061 T5–T6, mill finish or anodised.

04

Galvanised steel rails — cheaper and stiffer than aluminium, so used where spans are longer and weight is less critical. Many installers combine steel rails with aluminium clamps.

05

Rails with a top flange of 30–80 mm and a section height of 20–45 mm, in 1.5–2.5 mm material at 15–25 m/min.

06

Rails cut to the array row length, commonly 2.4 m to 6 m. Longer rails need more intermediate supports, so there is a trade-off between fewer joints and more mounting feet.

Line Composition

Recommended Configuration

A complete working line, not just the forming machine. Each item below is quoted as one package.

  1. 01

    3 T hydraulic decoiler and leveling unit, included as standard

    for aluminium we set a lighter decoiler tension, because the softer material stretches if it is pulled harder than it needs to be.

  2. 02

    Solar omega rail machine

    12–16 stations, with either a servo or gearbox drive at 5.5–11 kW, forming at 15–25 m/min. Aluminium generally runs faster than steel in this section class.

  3. 03

    Polyurethane guide rolls

    aluminium rails are usually mill finish or anodised, and anodised surfaces are the most easily marked. Polyurethane rolls, reduced forming pressure and smooth transfer tables are what keep a rail saleable.

  4. 04

    Servo drive where the rail range is wide

    changing between top flange and section height is a setup action, and the servo option makes that a control-panel job rather than a mechanical one.

  5. 05

    Hydraulic flying cut to length with batch counter

    rails are cut to the row length, and an array normally needs more than one length, so the batch counter holds the set together.

  6. 06

    A note on roll forming versus extrusion: roll forming is far cheaper beyond small volumes and it lets you run steel as well as aluminium on the same machine. Extrusion only wins where you need a complex closed section or very high stiffness in a short run.

How It Runs

Production Workflow

  1. 01

    Decoiler

    Coil is loaded and uncoiled at controlled tension. On aluminium the tension setting is critical: a rail that has been stretched does not recover its section, and it shows up as a curve along the array.

  2. 02

    Leveling

    The strip is straightened before forming. Because the rail presents a flat top face for the clamps, cross-bow cannot be hidden in a rib the way it can on a roofing profile.

  3. 03

    Roll forming

    12–16 stations form the omega or hat section at 15–25 m/min, producing a top flange of 30–80 mm on a section 20–45 mm high.

  4. 04

    Cutting

    A hydraulic flying cut cuts to the row length, with a batch counter. Typical PV rail lengths run from 2.4 m to 6 m.

  5. 05

    Output

    Rails leave on the runout, bundled by length. On anodised aluminium the bundling arrangement matters as much as the forming, because rails abrading against each other is a common cause of rejects.

Common Questions

FAQ — Solar Omega Rail Roll Forming Machine

What is an omega rail used for in solar mounting?
It is the horizontal rail that runs across the roof and carries the panel clamps, spanning between the roof hooks or mounting feet. Its hat-shaped section gives stiffness in the direction of the roof load while presenting a flat top face for the clamps.
Why roll form the rail instead of extruding aluminium?
Roll forming is far cheaper for anything beyond small volumes, and it lets you run steel as well as aluminium. Extrusion wins only when you need a complex closed section or very high stiffness in a short run.
Can the machine form 6063-T5 aluminium without scratching it?
Yes. Aluminium rails are usually mill finish or anodised, so we use polyurethane guide rolls, reduced forming pressure and smooth transfer tables. Anodised surfaces need the most care.
What rail length is typical?
PV rails are normally cut to the array row length, commonly 2.4 m to 6 m. Longer rails need more intermediate supports, so there is a trade-off between fewer joints and more mounting feet.
Should the rail be steel or aluminium?
Aluminium is lighter and does not corrode, which helps on large roofs where the structure has limited load capacity. Galvanised steel is cheaper and stiffer, so it is used where spans are longer and weight is less critical. Many installers use steel rails with aluminium clamps.
Does the machine include a decoiler?
A 3 T hydraulic decoiler and leveling unit are included. For aluminium, we supply a lighter-tension decoiler setting so the softer material is not stretched.
Can the machine be built for our own profile?
Yes. Send the profile drawing with the section dimensions, the material and thickness, and the coil width you intend to run. We confirm the roll design, forming stations and line layout against that drawing before quoting, so the machine matches the section you actually sell.
How do we get a price for this line?
Send the profile drawing or section dimensions, the material and thickness, the coil width, and your target output per shift. Price depends on the profile, the coil and the level of automation, so we quote against your actual job rather than a catalogue figure.
What material thickness can this machine form?
Material thickness runs 1.5 – 2.5 mm. The roll gap, drive and cutting unit are set for this range, so staying inside it is what keeps the section geometry repeatable run after run.
What is the production speed?
Forming speed is 15 – 25 m/min. Treat this as the line speed: real shift output also depends on cut length, coil reloading and how often the profile is changed.
How many forming stations does it use?
The line uses 12 – 16 forming stations. Station count follows the section — more bends and tighter tolerances need more forming steps, which is why two profiles rarely share one roll set.
What is the drive and installed power?
Drive: Servo or gearbox, 5.5 – 11 kW. Final drive sizing is confirmed against your profile and coil, because a wider or thicker section needs more torque to hold the same line speed.
