Aluminum Trailer Roof Coil refers to a large roll of aluminum sheet or coil specially designed for use as trailer roof material. Aluminum is a popular choice for trailer roofs because of its light weight, durability and corrosion resistance. The roll form facilitates transportation and installation, as the trailer roof material can be unrolled and cut to length on site.

Aluminum Trailer Roof Coil

While there is no comprehensive data, it is common to find that a significant portion of trailer roofs are made of aluminum. Steel is also used in some cases, especially heavy trailers or applications that require extra strength. Fiberglass, on the other hand, is relatively uncommon for trailer roofs, but can be used in some specialty trailers, such as recreational vehicle (RV) or horse trailers.

3003 H14 H16 Aluminum Coil for Trailer Roof

Aluminum trailer roof rolls are usually made from high-quality aluminum alloy sheets that have been specially treated to enhance their strength and weather resistance. Coils are available in various thicknesses and widths, allowing trailer manufacturers to select the size that best suits their particular application.

The specific alloy number and temper of the aluminum alloys used for aluminum trailer roof coils may vary by manufacturer and their specific requirements. However, one common alloy used for such applications is 3003 aluminum alloy in the H14 or H16 temper.

Alloy 3003 is a non-heat treatable alloy with excellent corrosion resistance. Commonly used in a variety of applications requiring moderate strength and good formability. Adding manganese to the alloy increases its strength and makes it easy to work into different shapes.

  • H14 represents the strain hardening state, which means that the aluminum alloy has undergone a cold working process to increase its strength.
  • The H16 temper also represents the strain hardening state, but is slightly stronger than H14.

3003 H16 Aluminum coil for trailer roof condition offers good strength and stability which is ideal for roofing applications where the material needs to withstand a wide range of weather conditions.

3003 Aluminum Tensile Strength (MPa) Yield Strength (MPa)
3003 H14 Aluminum 130-180 85-145
3003 H16 Aluminum 160-200 140-180
3003 Aluminum Elongation (%) Hardness (Brinell)
3003 H14 Aluminum 10-14 40
3003 H16 Aluminum 5-10 50

The specific alloy and temper used for Aluminum Trailer Roof Coil may vary depending on the manufacturer's specifications and intended application. It is always advisable to consult the manufacturer or supplier for accurate information on the alloys and tempers used in their products.

Aluminum Coil for Trailer Roof Advantage

  • Lightweight : Aluminum is much lighter than many other roofing materials such as steel. This lightweight feature of aluminum reduces the overall weight of the trailer, which improves fuel efficiency and increases payload capacity.
  • Corrosion Resistance : Aluminum has excellent corrosion resistance, especially when compared to materials such as iron or steel. It is highly rust-resistant and can withstand moisture, UV rays and harsh weather conditions, making it suitable for outdoor applications such as trailer roofs.
  • Durability : Aluminum is a durable material that can withstand impacts and harsh environments. It is less likely to crack, warp or become brittle, ensuring the longevity and structural integrity of your trailer roof.
  • Formability : Aluminum can be easily formed and molded into various configurations, allowing for custom designs and easy installation on trailer roofs. It molds to fit the contours of the trailer, creating a seamless and visually appealing look.
  • Thermal reflectivity : Aluminum has a high thermal reflectivity, which means it reflects a large portion of solar radiation. This reflective property helps reduce heat gain, keeping the trailer interior cool and improving energy efficiency.
  • Recyclability : Aluminum is highly recyclable, making it an environmentally friendly choice. It can be recycled repeatedly without losing its properties, reducing waste and promoting sustainability.
  • Aesthetic Appeal : The aluminum coil used for the roof of the trailer has a simple and modern appearance. It can be finished with different coatings and finishes to enhance its visual appeal, giving the trailer a stylish and attractive look.
  • Low Maintenance : Aluminum requires minimal maintenance compared to other roofing materials. It does not require regular painting or sealing, and is resistant to staining and discoloration, reducing the need for frequent cleaning or repairs.
  • Wide availability : Aluminum coils for trailer roofs are available in a variety of sizes and thicknesses, making them easily available to manufacturers and builders.
  • Cost Effective : While aluminum may have a higher upfront cost compared to some materials, its long-term benefits such as durability, low maintenance, and recyclability make it a cost-effective choice for the life of the trailer.

Typical Aluminum Alloy for Trailer Roof

In addition to the aforementioned 3003 aluminum alloy, there are other aluminum alloys that can be used for trailer roof membranes, depending on specific requirements and preferences. Here are some examples :
