Aluminum gutter coils are the foundation of a high-quality rainwater management system. Whether you are a homeowner or a contractor, choosing the right material is essential.

Popular Sizes and Dimensions
Choosing the right width is the first step in your project. The width of the coil determines the size of the final gutter.

5-Inch Gutter Coil Width

For standard residential homes, the 5-inch gutter is the most common. The coil width used for this is typically 11.75 inches or 11.875 inches.
6 Gutter Coil Width

For larger homes or commercial buildings with steep roofs, a 6 Gutter Coil width is required. This usually uses a $$15$$-inch wide aluminum strip. This size can handle a much higher volume of water during heavy rain.
What Gauge are Aluminum Gutters?
If you are wondering what gauge are aluminum gutters, the industry standard is usually 0.027 inches for residential use. For heavy-duty or commercial applications, a thicker gauge of 0.032 inches is preferred to prevent sagging and withstand heavy snow loads.
Types of Aluminum Gutter Coils
There are several types of gutter coils available to match different architectural styles.
1. Pre-Painted Aluminum Coils

These are the most popular. They come with a factory-applied finish in various colors like white, black, brown, and cream. The paint is baked on to prevent peeling or cracking.
2. Embossed (Stucco) Gutter Coils
These coils have a textured surface. The texture helps hide scratches and small dents that might happen during installation or from ladders.
3. Woodgrain Coils
Some Gutter coil manufacturers produce coils with a woodgrain pattern. This gives the appearance of wood but with the durability and low maintenance of aluminum.
4. Gutter Heating Coils

In cold climates, Gutter Heating coils (also known as heat cables) are installed inside the gutters. These help prevent ice dams from forming, which can damage the roof and the gutter system.
Applications of Aluminum Gutter Coils
Aluminum gutters are versatile and used in many different settings. Here are the primary application areas:

- Residential Homes: Protecting foundations and landscaping from water damage.
- Commercial Warehouses: Managing large volumes of water on flat or sloped roofs.
- Agricultural Buildings: Directing rainwater away from barns and livestock areas.
- Industrial Plants: Used in environments where corrosion resistance is vital.
- Renovation Projects: Replacing old, rusted steel gutters with lightweight aluminum.
Technical Performance and Alloys
The performance of your gutter depends on the metal chemistry. Let’s look at the common alloys used by aluminum gutter coil wholesale suppliers.
Alloy 3003
This is the most widely used alloy for gutters. It contains manganese, which increases its strength while remaining very easy to form in a Gutter Coil machine.
Alloy 3105
This alloy is often made from recycled aluminum. It is very eco-friendly and has excellent corrosion resistance. It is slightly more rigid than $$3003$$.
Tempers and States
- H14: This is a “half-hard” temper. It provides a good balance between strength and the ability to be bent without breaking.
- H24: This is similar to $$H14$$ but achieved through a different heating process. It is very stable and holds its shape well.
Installation: How to Join and Seal
Even if you have the best aluminum gutter coils, poor installation will lead to problems.
How to Join Two Pieces of Aluminum Gutter
To join two lengths of gutter, you should overlap them by at least $$2$$ to $$3$$ inches.
- Apply a bead of sealant between the overlapping layers.
- Use pop rivets or zip screws to secure the pieces together.
- Ensure the “upstream” piece is tucked inside the “downstream” piece so water flows over the seam, not into it.
What is the Best Sealant for Aluminum Gutters?
When looking for what is the best sealant for aluminum gutters, experts recommend high-grade Gutter Sealant or Butyl Rubber sealant. These materials remain flexible in cold weather and resist UV rays. Avoid using standard bathroom silicone, as it may not bond well with the painted aluminum over time.
Gutter Coil Calculator: Planning Your Project
Before you call Gutter coil suppliers near me, you need to calculate your materials. A Gutter coil calculator typically uses the following formula:
- Measure the total linear footage of the roof edge.
- Add 10% extra for waste and overlaps at the miters (corners).
- Determine the weight. Aluminum coil is often sold by weight.
- For 0.027 gauge, 1foot of 5-inch gutter coil weighs approximately $$0.38$$ lbs.
- For 0.032 gauge, it weighs approximately 0.45 lbs.
Estimated Material Table
| Roof Length (Feet) | Recommended Coil Gauge | Total Weight Estimate (lbs) |
|---|---|---|
| 100 | 0.027 | 40 – 45 |
| 250 | 0.027 | 100 – 110 |
| 500 | 0.032 | 230 – 250 |
Buying and Pricing
If you are a contractor, buying Gutter coil wholesale is the best way to save money.
Aluminum Gutter Coil Price Per Foot
The Aluminum gutter Coil price per foot fluctuates based on the global price of raw aluminum. Factors that influence the price include:
- The thickness of the gauge (0.032 is more expensive than $$0.027$$).
- The type of coating (Custom colors or PVDF coatings cost more).
- The volume of the order (Buying in bulk reduces the price).
Finding Gutter Coil Suppliers Near Me
When searching for aluminum gutter coil suppliers, look for companies that offer delivery directly to your job site. Many suppliers provide “drop-off” services where they bring a truck and a machine to run out the gutters for you if you don’t own a machine.
What are Aluminum Gutter Coils?
Aluminum gutter coils are long strips of aluminum alloy rolled into a coil. These coils are fed into a Gutter Coil machine to create seamless gutters directly at the job site. Because they are seamless, they reduce the risk of leaks and provide a clean look for any building.
Key Specifications of Aluminum Gutter Coils
When looking for aluminum gutter coil for sale, you must understand the technical properties. Most manufacturers use the 3000 series aluminum alloys because they offer excellent strength and corrosion resistance.
| Feature | Specification Details |
|---|---|
| Common Alloys | 3003, 3105, 3004 |
| Temper (Hardness) | H14, H16, H24 |
| Thickness (Gauge) | 0.027 inch, 0.032 inch |
| Standard Widths | 11.75 inches, 11.875 inches, 15 inches |
| Coating | Polyester, Polyurethane, or PVDF |
Maintenance and Long-Term Care
To get the most out of your aluminum gutter coil investment, follow these simple steps:
- Clean twice a year: Remove leaves and debris to prevent water from sitting and causing oxidation.
- Check the seals: Inspect the joints once a year. If you see drips, re-apply the gutter sealant.
- Check the hangers: Ensure the hangers are tight. Heavy snow can sometimes pull them loose.
Why Choose Aluminum Over Other Materials?
| Feature | Aluminum | Steel | Vinyl |
|---|---|---|---|
| Rust Proof | Yes | No | Yes |
| Life Span | $$20+$$ Years | $$10-15$$ Years | $$10$$ Years |
| Expansion | Moderate | Low | High |
| Installation | Easy (Seamless) | Difficult | Easy (Sectional) |
