Choose material for drainage channel

Learned something new
Then I will get a channel made of polymer concrete with a grate made of cast iron.

Thank you very much!

Hello, is there any experience (long-term?) with plastic gutters? For example, arco hexaline 2.0. Use as a gutter in front of the facade/patio doors, pedestrian only.

Concrete gutters unfortunately do not look very good, especially in the terrace area. Plastic gutters with a designer grate would be okay, right? It's about approx. 11m house + 8m garage, where I have 2x90° changes in direction.
Insider tip?

I installed some gutters in 2014.

Brand unknown. I still have half a meter lying here, let's see if something can be found.

The gutters themselves are all made of plastic.

At the driveway, some with cast iron grates were installed.

At the side door of the garage, one with a plastic grate.

So far, there have been no problems with them.
