Hi, i would use zincalume, rather than galv, it may be a bit dearer, but i think it looks a lot better.

yep.i've been building for 30 years and have never seen a tradesman -roofer or builder cut roofing with a skilly-gilbows proper roofing gear and left /right hand snips

Jeppers some people like to over complicate their lives. $15 pair of tin snips from the tool shed works for me - no fuss no mess quick and easy. Once you realise they actually make a tool for the job your away.

Zincalume and galv are both bare product, very little difference in the look of them and zinc is cheaper.

Its really easy with a metal cut off wheel on an angle grinder. Sandwich the ends of the sheet between 2 bits of 2 x 4 and away you go. The width of the wheel keeps the cut nice and straight and its much more fun than snips.

Just order the size you want - tidier and easier.

Cant order the size you want. You can order length wise, but they dont cut to width.
Manufacturers, suppliers recommendation. Use a nibbler or shears. Using grinding wheels will generate too much heat which will cause their products to rust.
Straight from the horses mouth. Bummer is I have a diamond edge cut off wheel for my angle grinder.
And I dont trust myself to get a nice edge with the sheers, so off to buy a nibbler.

which cut is the issue there is any amount of gear for across corro, but very little for down the length, and that is a prick of a cut to get clean, snips are a total arse to use for it An old guy once showed me how to split corro lengthways using a couple of 4x2's nailed to a bridging block, he used the back edge of a standard handsaw, and it made a lot of very clean cuts that day If you're interested I'll draw up a diagram and post it

Length wise cuts are very easy. But OP clearly isn’t asking for that

I read that as him saying because he isn’t a tradie he doesn’t think he can Roll formers will do it for anyone

The suppliers will cut the tin to any length i want. They state they cant cut to width. Width comes at 840 and Im stuck with that. Most of the hole sizes are 830ish. So Im going to have to find a way to cut down the whole length of the tin.
Thank you skin1235, thats a really nice offer but I think nibblers going to be my best bet. Should be quite simple with a nibbler. And they are quite cheap on trademe. I just hope the cheapies are up to the job. See some $40 air ones on here. Might just grab one of them.

its really easy to cut long ways. The first method is to simply get a gib board cutter and chop it down the line you want. Thats the way its fastest when you have a flashing to cover it. the other way is to mark the iron top and bottom where you want the cut to be , then get a strong craft knife (or similar) and score a line down the iron two or three times. Then simply turn it over and fold it back along the line and it will simply snap off along the score mark. I guess I should do a youtube video to demonstrate.
What a butcher you would be , certainly not a tradesman .

# 45 & #46 Good thinking looks a lot easier than using an axe- machete-spade-or yer mates bestest chisel.

A mate of mine bought some cheap nibblers to cut some corrugated iron at home, and said they were so useless he had to give up on them. He has his own metal fabrication business, so I trust he knew what he was doing, and it wasn't user error or incompetence. He borrowed some trade quality nibblers from another mate, and said they were easy to use and did a perfect job. So it sounds like you get what you pay for with nibblers, and it might pay to search for user reviews if you plan on buying cheap ones.

That’s how it’s done. The cut edge has at least 150mm of flashing covering it, so it’s never seen. No swarf , no nibbler filings . It’s the best way. What’s your method?

Im gunna try that. I've always used the back tooth of a handsaw or a Hardies Score 'N Snap knife.

What I was hoping for was a nice clean cut so that I dont have to cover it with flashing. I was trying to avoid the work of making up extra flashing. Although not the end of the world though. I like the idea of scoring it with a stanley knife and breaking it. Seems pretty easy. will give that a shot.
cheers to the others re-info on cheap nibblers. Will avoid.
Thanks for all the help guys. Much appreciated.
Pick up the iron next week. will let you know how it goes.
