What are double tees in roofing?

Double tees are precast concrete members that are widely utilized in decking systems in roofing architecture. These structural components are designed with a distinctive “T” shape when viewed in cross-section, which allows them to support significant weight while maintaining structural integrity. Their design facilitates efficient load distribution across the roof, making them particularly useful in large open spaces, such as in commercial and industrial buildings.

The use of double tees provides several advantages, such as allowing for quicker installation compared to traditional cast-in-place methods, as they are manufactured off-site in controlled environments. This can lead to reduced construction time and labor costs. Additionally, they can be made to precise specifications, ensuring consistency and quality in the roofing structure.

This understanding of double tees is essential for anyone involved in roofing systems, as they are a critical component in achieving strong, durable, and efficient roof designs. The focus on their structural attributes highlights their role in supporting the overall integrity of roofs in multi-story buildings or expansive structures.
