    With regards to downpipes, which one is better between colorbond square ones (100 x 75mm) vs PVC round ones (90mm)?

    I haven't seen many house with PVC downpipe connecting roof guttering.

    PVC is much cheaper a 6m liner for $14.

    Any advice is helpful.

    Just different flow rates,100x75 is not used much these days most are 90mm round,or some upmarket use stainless steel marine grade 316 ,the stainless stands out and outlast everything..imho..

    Thanks Will for the fast reply.

    So you're saying:

    The round one PVC Cross sectional area = 6361.725mm^2
    While colour bond square one Csection area = 7500mm^2

    So the colour bond one is better in terms of flow rate?

    Are there any other differences? in terms of lasting test of time? both the same?

    Which one would you choose?
    Anyone else with advice??

    I'd recommend PVC round, no rust, no corners for twigs to get caught up on etc, if pos try not to use any 45deg

    Colour bond is sometimes a stand out,does not need repainting for quite a long time,i,m not that good on lasting times but both would be in the same timeframe,may well depend on the timeframe of the house .imho..

    75 x 100mm has a higher capacity 7500 mm^2 vs 6362 mm^2 or 18% more).

    It doesn't much matter whether you use pvc or colorbond but you need to allow for painting if you select pvc (between 0.28 m2/m round or 0.35 m2/m rectangular).

    Metal dents/crushes but is more durable vs pvc which is resilient but can become brittle when impacted.

    When it comes to depreciation, you may try to claim the painting on a more regular basis vs on the capital cost of the metal.

    Have your roof plumber size the spouts etc as incorrect selection may cause water ingress into the building.
