PAINT-COATED RAINWATER STANDPIPES FROM GRÖMO - THEY STAND UP GREAT.

High standards, high performance.

The standpipe forms the connection between the downpipe and the sewer pipe. Thus the pipe is especially susceptible to all kinds of damage here, be it from the lawn mower, snow shovel, brush, traffic or weathering. This is why standpipes are extremely robust and made from resilient materials.

We use galvanised steel for our standpipes because we value the quality of our products very highly. Thus they are corrosion-resistant, made to last, sturdy and functional. The standpipes are available in 7 colours: anthracite, brown (Testa di Moro), light grey, white, moss green, brick red or oxide red. For even more individuality, GRÖMO gives you the option to choose the colour of your roof drainage system from 206 additional colours in the RGB colour space.

We also keep matching rainwater standpipe brackets with threaded nuts in our range since the rainwater standpipes also have to be fixed to the wall. Fast and easy to mount, they make sure that nothing slips out of place.
