What Is Gutter Coil?
Posted
Gutter coil is flat metal, rolled up. Your gutter machine shapes this coil into seamless eavestrough right on the job. This explains what it is, how we measure it, and what to look at before you get it.
A foam gun controls expanding foam output. Learn how to adjust it, use it, and clean it for the next job.
If you are pricing a run or setting up a machine, the coil has to match the profile, width and thickness that machine runs. Get that wrong and the coil will not form the gutter you need.
The short answer
You get a steady foam bead with a foam gun, not a messy spurt from a straw. The key is a controlled bead. Make sure your gun fits the foam can, adjust the flow screw before you squeeze.
You buy gutter coil by the material, width, thickness, and finish. It's not a finished gutter length you buy off the shelf. The coil is just the material. The machine makes the gutter.

What you need before you order
Match the coil to the machine first. The machine's manual or the profile supplier tells you the developed width and the thickness range it accepts. Developed width is the flat width the profile needs, not the width of the finished gutter.
Then decide the material and finish. Aluminum is the common gutter coil material, and the cluster terms around this topic also cover buying aluminum stock and bending aluminum trim coil, so the same flat-stock questions come up across trim and gutter work.
Have the run length and the number of corners and outlets ready. Those drive how much coil you need and how much offcut you will carry.
How the coil becomes a gutter
Measure the run, then add for corners, outlets and the ends. Work in the developed width the profile needs, not the finished gutter width.
Set the machine to the profile and thickness you are running, then feed the coil and check the first length before you run the whole job. If the first length does not form cleanly, stop and check the setup rather than running more coil through it.
Form the lengths, cut them, and fit them. Keep the offcuts; short pieces are useful for corners and repairs.
Mistakes and limits
The most common mistake is ordering by finished gutter width instead of developed width. The coil will not run to the profile you need.
The second is assuming coil is interchangeable between machines. Profile, width and thickness have to match the machine, and a coil that runs on one machine may not run on another.

Where to go next
If you know the profile, width, thickness and finish your machine runs, open the aluminum products category or send Cranco those details. That is the mapped next step for this topic.
If you are still working out the profile, get that from the machine manual or the profile supplier first. The coil order follows from the profile, not the other way round.
Is gutter coil the same thing as a finished gutter?
A gutter coil is just flat metal, not a finished gutter. A machine at the shop or on the truck shapes the coil into the gutter. The coil is the base material; the machine makes the final shape.
What do I need to match before ordering coil?
Match the coil to your machine. Look at the profile the machine makes, the coil width and thickness it takes, and the metal type you want. If these don't match, the coil won't form right or will jam the machine.
How do I work out how much coil to order?
Measure the developed width the profile needs, not the width of the finished gutter. The machine's manual or the profile supplier gives that number. Ordering by the finished gutter width is the most common way to end up with coil that will not run.
Where do I go next if I am ready to buy?
It is a learn-intent topic, so the useful next step is to confirm the profile, width, thickness and finish your machine runs, then open the aluminum products category or send Cranco those details. This page does not quote price, branch stock or stocked colours.
