Kommercial is a large-capacity system (160mm and 200mm) built for commercial, agricultural and large buildings where standard domestic profiles cannot cope with the roof area.
Key specifications
| Profiles | 160mm & 200mm Kommercial |
| Style | Large half round |
| Downpipe | 110mm round |
| Flow capacity (level) | from 4.60 l/s |
| Bracket spacing | 600–800mm |
Best suited to
- Commercial, industrial and agricultural buildings
- Large roof areas and long unbroken runs
- Sites where domestic profiles would over-run
Fitting notes
Use the closer 600–800mm bracket spacing for these heavier, high-capacity systems and plan outlet positions to suit the roof area.
Fix an extra bracket within 150mm of every union, angle, running outlet and stop end, and lay the gutter to a slight fall of about 3mm per metre (1:350) towards the outlet. Leave the manufacturer's 6–10mm expansion gap at union joints, and space downpipe clips no more than 1.8m apart with support near the top and bottom of the run.
Colours
Black and Grey.
Compatibility
A commercial profile — do not assume standard domestic fittings will work. Broadly aligns with Hepworth, Marley, Osma/Wavin and Polypipe commercial systems; confirm before mixing.
Always confirm the profile before mixing parts — see the gutter compatibility guide.
