Corrugated panels

[yzair]

I have to cut about 20 panels of 22 gauge corrugated to install on a ceiling. some will need square cuts approx. 18" x 18" for a/c ducts some in the middle of panels as well as other holes and notches for various items in ceiling framing.

Are they straight or curved cuts? I've seen nibblers used for curved cuts. For simple straight cuts, I always thought you could sandwich it between two pieces of the wavy-surface board and then use a circular saw with a metal-cutting blade -- or even a jigsaw.

Metabo on the straight cuts inside a panel,for cutting to length,a metal cutting blade in a skill saw. The blades are not cheap,I just replaced mine a couple weeks ago,it was $50,but I built two buildings with the old one.Plunge cutting metal with a skill saw is a very dangerous thing to do.

Well it's a little of everything there are some 4"round can lights and different size a/c supply ducts 4x8 6x10 it's going in an art gallery they wanted something different.
I'm thinking of boxing all the lights w/ like metal studs (tin can studs) on the 1 1/2 side then putting flat piece of tin over that and cutting 4" holes w/ hole saw. Kind of picture frame lights maybe a/c too! Still have to cut holes in middle of sheets ? or where ceiling stuff lays out.

Ok, so what are you trying to find out? Your post is a statement with no questions!

If you are trying to find out what you use to cut roofing material, just grab a junk blade for your skil saw, install backward and go to town. Wear ear protection, it's very loud!

Have you tried aviation tin snips? 22 gauge is pretty light material.

plywood blade and a saber saw with metal blade ....and cut at will

use ear plugs ...

If you don't have many to do, drill holes at corners and use tin snips. Man it's loud and a pain to use jig saw or circular saw and get it looking right is hard. Plus the metal sparks cause rust spots on painted panels.

Air shears work great and are reasonably priced. Nibblers are slower and noisier. Hole
saws for round cuts. Straight screwdriver and a hammer for rectangular small box cuts.
The backward saw blade does work good but is unbelievably noisy. We left the ceiling
boxes with slack wire floating above the ceiling joist and then made the layout work
with the flat sections of the metal ceiling. Much cleaner look and simpler to cut.

We don't have flat sections on our corrugated sheets here in NZ.
Just 1/2 round up and down bits.. lol
