6″W x 4″H American Made Urethane Top Rail (BR7500)

American Made Urethane Top Rail (BR7500, sold in 2’ increments.) outlasting resin, plastics, and wood products, not cracking, warping, or splitting, being waterproof, made of solid urethane, and lightweight—I recommend looking into High-Density Urethane (HDU) or similar materials. HDU is a type of solid urethane material that is often used in applications where durability, resistance to environmental factors, and lightweight properties are essential.

Here are some key characteristics of American Made Urethane Top Rail (BR7500) that align with your criteria:

1. Durability: HDU is known for its durability and resistance to cracking, warping, and splitting. It can withstand various weather conditions and is less prone to damage compared to traditional wood products.
2. Waterproof: HDU is inherently water-resistant, making it suitable for outdoor applications. It won’t absorb water, preventing issues like rot or decay that can occur with some wood products.
3. Solid Urethane: HDU is a solid, homogeneous material, providing consistent properties throughout its structure. This contributes to its stability and resistance to structural issues.
4. Lightweight: HDU is significantly lighter than many traditional materials, such as wood or metals, making it easy to handle and install. This can be an advantage in applications where weight is a consideration.
5. Ease of Installation: HDU is typically easy to work with and can be cut, shaped, and installed using standard tools. Its lightweight nature also simplifies the installation process.

Before proceeding, it’s important to verify the specific product specifications with the manufacturer to ensure that the chosen HDU product meets your project requirements. Additionally, consider factors such as UV resistance if the material will be exposed to sunlight, as some materials may degrade over time when exposed to intense sunlight.
