Aluminum Trim coil is typically used for decorative purposes, such as adding a finishing touch to the exterior of a building. It can be used for a variety of applications, including fascia, window and door casings, and trim around eaves and gables. Trim coil is available in a range of colors and finishes, allowing it to match the existing exterior of a building.

Aluminum Gutter coil, on the other hand, is designed specifically for the fabrication of gutters and downspouts. It is thicker and wider than trim coil and is typically used for larger applications. Gutter coil is also available in a range of colors and finishes, allowing it to match the existing exterior of a building.

5 Differences Between Aluminum Trim Coil and Aluminum Gutter Coil

• Purpose and Applications of Aluminum Trim Coil and Aluminum Gutter Coil

Trim coil is primarily used for decorative purposes, such as adding a finishing touch to the exterior of a building. It can be used for fascia, window and door casings, and trim around eaves and gables.

Gutter coil, on the other hand, is designed specifically for the fabrication of gutters and downspouts.

• Thickness and Width of Aluminum Trim Coil and Aluminum Gutter Coil

Trim coil is thinner and narrower than gutter coil. It typically ranges from 0.018 to 0.024 inches thick and 24 to 36 inches wide.

Gutter coil is thicker and wider than trim coil. It typically ranges from 0.027 to 0.032 inches thick and 11.75 to 20 inches wide.

• Coating and Finish of Aluminum Trim Coil and Aluminum Gutter Coil

Both trim coil and gutter coil are available in a range of coatings and finishes. Trim coil may be coated with a variety of finishes, including PVC, polyester, and acrylic, while gutter coil is typically coated with a durable, baked-on enamel finish.

Gutter coil is usually coated with a thicker and more durable finish than trim coil, since it is exposed to the elements and must withstand harsh weather conditions.

• Color Options of Aluminum Trim Coil and Aluminum Gutter Coil

Both trim coil and gutter coil are available in a wide range of colors to match the existing exterior of a building.

Trim coil may offer a wider range of color options than gutter coil since it is primarily used for decorative purposes.

• Cost and Availability of Aluminum Trim Coil and Aluminum Gutter Coil

Trim coil is generally less expensive than gutter coil due to its smaller size and lower thickness.

Both types of coils are widely available, although availability may vary depending on the specific color, finish, and size required.

In summary, while both trim coil and gutter coil are made from high-quality aluminum and are designed for the construction industry, they differ in purpose, thickness and width, coating and finish, color options, and cost and availability. Understanding these differences can help in selecting the right type of coil for a specific application to ensure maximum performance and longevity.

Benefits and Limitations of Aluminum Trim Coil and Aluminum Gutter Coil

Benefits of Aluminum Trim Coil

• Versatility: Trim coil can be used for a variety of decorative purposes in the construction industry, such as finishing the exterior of a building, adding accents to windows and doors, and wrapping columns and beams.
• Aesthetics: Trim coil comes in a wide range of colors and finishes, which can be customized to match the existing exterior of a building.
• Cost-effective: Trim coil is generally less expensive than gutter coil, making it an affordable option for decorative purposes.

Limitations of Aluminum Trim Coil

• Durability: Trim coil is not as durable as gutter coil since it is not designed to withstand harsh environmental conditions, such as rain, snow, and extreme temperatures.
• Limited size options: Trim coil is typically narrower and thinner than gutter coil, limiting its use in larger construction projects.

Benefits of Aluminum Gutter Coil

• Durability: Gutter coil is designed specifically for use in gutters and downspouts, making it durable enough to withstand harsh environmental conditions.
• Customizable: Gutter coil comes in a range of colors and finishes, which can be customized to match the existing exterior of a building.
• Easy to fabricate: Gutter coil is easy to work with and can be easily fabricated into custom sizes and shapes.

Eavestrough Thermal Expansion Chart

We've all experienced different temperatures of the seasons throughout the year, and our bodies react differently to each one. Well, eavestrough acts similarly by distorting the aluminum, and it's called thermal expansion. 

Thermal expansion happens when aluminum is exposed to changes in temperature and begins to expand or contract. This conflicts with the hangers that are supporting the eavestrough up.

For example, if a 35' section of eavestrough was installed at 10â&#;ƒ, it will expand by 1/2" at 40â&#;ƒ. That 1/2" is enough to cause damage, such as oil canning, buckling, or in extreme cases, the eavestrough will split.

Some precautions can be taken to eliminate the possibility of these things happening:

1. Limit the run of the eavestrough, as it's recommended that lengths should not exceed 50'. For sections that are longer than 50', the best suitable solution would be to run shorter lengths, leave a gap in between each section, and fasten an end cap to seal off the end. *See picture.

2. Because temperature plays the most significant role in thermal expansion, it's best to avoid installing eavestrough in colder temperatures. The best temperature range to install eavestrough would be 15-30â&#;ƒ. 

3. Make sure to adjust your trough machine regularly to guarantee the eavestrough is formed without any curving or buckling happening. 

4. Trough run-off stands should be set 10' apart and lined up perfectly with the trough machine for support. This would help prevent any stretching or distorting of the eavestrough.

With these suggestions, you may reduce the chances of damages occurring. This will save you time, and money and it will keep eavestroughs performing like new for years to come!
