Pre-Topped

Definition

Pre-topped refers to a factory-topped double tee section with the entire deck thickness integrally cast.

Purpose

Pre-topped double tees are used in construction to provide a strong, durable, and ready-to-install flooring or roofing system. The integral casting of the deck thickness ensures a uniform and continuous surface, reducing the need for additional topping or finishing on-site.

Examples of Use

• Parking Structures: Used for creating the floors of multi-level parking garages due to their strength and ability to span long distances.
• Commercial Buildings: Providing floors and roofs in commercial construction projects.
• Industrial Facilities: Used in warehouses and manufacturing plants for robust and load-bearing floors.

Related Terms

• Double Tee: A type of precast concrete element with two parallel beams (or "tees") and a connecting deck, used for flooring and roofing.
• Precast Concrete: Concrete elements that are cast and cured in a controlled environment before being transported to the construction site.
• Topping Slab: An additional layer of concrete placed over precast elements to provide a finished surface.

Notes

• Installation: Pre-topped double tees are installed on-site, typically requiring less finishing work than non-topped elements.
• Advantages: Provides a uniform, smooth surface that is immediately usable after installation, saving time and labor.
