whats an alternative to 22m of trunking conduit???

[wozzzzza]

i wanted to lay 22m of 75x75mm trunking conduit along a top of a wall so it looks like its part of the building and not use round stuff but when i looked at the price of a 4m length of this stuff its around $150, i almost fell off my chair. i had to read the listings and look at a few different places to believe it as i thought it might have been a pack of 5 or something for that price but it wasn't.
why is this stuff soo damn expensive??
it will cost me almost $1k to run 22m of conduit. not going to happen.
what can i use as an alternative to this stuff that is around a quarter of the price? anyone got any ideas?
needs to be something that can be easy to add new cable to at a later date when i need to run more through it unlike round conduit which is real hard to do.
ideas??

You dont mention what service it needs to carry apart from "cable", so any regulation aside:

Air con conduit ?
75mm Duct Cover Plastic 2 meter length | 8 Buy only | SD-75-8 - Complete Air
and joiners
75mm Air Conditioner Joiner | SJ-75 - Complete Air

16 metres for ~ $130:00

lots of low voltage twin cable and network cables, no 240v stuff.
not really a fan of that a/c ducting, but if i have to i have to.
any other ideas?

A sheet metal supplier should be able to fold something up, two U shaped sections. Wont have nice joiners or end sections like a commercial conduit.

Rectangular pvc downpipe? Not quite size but cross section area not lot difference
galvanised downpipe, custom made

not really sure if it meets regs...

can you put the cable in a proper conduit, the cheapest thing you can find. and then run that conduit in whatever PVC, metal, guttering etc pipe that looks nice?

Probably best suggestion so far.
Colorbond downpipe comes with big end small end for joining.
Comes in 1.8, 2.4, 3, and 3.6 Metre lengths if I remember correctly.
100x75 most common size.

hard to run more cable after that is the issue

Leave a drawstring or two in the conduit when you do the first install?

There is so much room in the 100x75, you could either pull through a drawstring as your pulling through you new cables or push through 5 lengths of 20mm conduit to attach a new draw string...should slide through easy.

Other than that, have someone fold you up a box out of colorbond. Quash fold the front top side to take away any sharp edges and with a 10mm lip on the top fold so it covers the squash fold on the side and water tight. You can just open slightly and slip your new cables in when required.

i have found it, i will be using 80mm cool duct. it is pretty much the same as trunking conduit and 10 times cheaper.

Google of “cool duct” or “80mm cool duct” does not return any specific matches for the item.
Care to share a link for reference ?

that's just it, i cant find it either, here's a pic of an aircon job i did earlier in the year using it. apparently exclusive to acdtrade, i had to call them today to find out about it.
