Mounting profiles for PV panels: aluminium rails and roof brackets
Mounting profiles in this category are aluminium 6060 rails and roof brackets for building photovoltaic sub-structures. The range covers 40x40 mm, 80x40 mm and 45x40 mm rails, plus trapezoidal brackets with EPDM seal. They are intended for installers and builders who fix PV modules on pitched and trapezoidal sheet metal roofs.
What you will find in this category
- 40x40 mm PV rails in lengths from 10 cm to 665 cm, with two channels, for M10 hex bolts or 28/15 hammer head bolts.
- 80x40 mm rails, 420 cm and 665 cm, installed with 3x DIN 933 M10 bolts and M8 T-nuts.
- 45x40 mm rail, 665 cm, with an additional cable channel, for M10 bolts.
- Trapezoidal brackets, hooks and bridges H-30 to H-100 with EPDM seal, 330 mm or 400 mm long.
- Natural aluminium and black anodised versions of the rails.
How to choose
- Bolt type: choose M10 DIN 933 hex bolt or 28/15 M10 hammer head bolt profiles to match the bolts you use.
- Cross-section: 40x40 mm is the most common. Choose 80x40 mm for larger rails, or 45x40 mm if you need a cable channel.
- Length: rails run from 10 cm to 665 cm. Several products can be extended with connectors for longer runs.
- Finish: choose natural aluminium or black anodised. Both use the same 6060 alloy.
- Roof bracket: select the height (H-30 to H-100) and length (330 or 400 mm) for your trapezoidal sheet roof.
Typical applications
The rails form the load-bearing structure of photovoltaic installations on pitched roofs. Module mid and end clamps fit in the upper channel. The lower channel connects to adapters, roof hooks or triangular brackets. On trapezoidal sheet metal roofs, the EPDM-sealed brackets are fitted on the rib crest and carry the rail or module directly.
Frequently asked questions
Which bolts fit the 40x40 mm rails?
Depending on the version, M10 DIN 933 hex bolts or 28/15 M10 hammer head bolts with M10 flange nuts. The product name states the bolt type.
Are the rails available in black?
Yes. Many rails are offered in a black anodised version, in addition to the natural aluminium finish.
Can I make a longer rail run?
Several profiles are described as extendable with connectors, so you can build longer installations from shorter rails.
