Double Tee Members

Double tees offer beauty and flexibility in design.

These precast/prestressed concrete units are ideal for floor and roof systems requiring long, uninterrupted spans and extra heavy load carrying capabilities resulting in lighter weight structures. Prestressed concrete double tees allow for longer spans with shallower depths and thinner sections resulting in fewer beams and columns which provides the owner with more useable floor space. For this reason, prestressed double tees are ideal.

General Information

DOUBLE TEES offers the developer / owner many key benefits:

Durability and fire resistance means low insurance costs and greater personal safety. Those who investigate life-cycle costing will appreciate prestressed concrete double tees high fire resistance characteristic. Prestressed concrete double tees can improve the thermal storage potential of a building. It effectively conserves energy required for heating and cooling.
The remarkable strength of a double tee is the result of a design and manufacturing system that uses the best attributes of steel and concrete. Consider double tees for long spans and heavy loads which exceed the capacity of hollowcore plank.

Double tees are known for their great resiliency. Long spans with exposed ceilings require no additional finishes. Superior smooth steel form finishes as well as excellent fire ratings are provided by double tee construction. Double tees can be designed to allow openings to be placed in the flange areas between the stems. This allows for the installation of electrical / mechanical ducts or windows/skylights.
Typical building uses for double tees include parking decks, water/wastewater treatment plants, food processing plants, heavy industrial buildings, warehouses, indoor pools and gymnasiums.
Strescon Limited can provide budget pricing and technical assistance at the preliminary design stage for your next project.

DOUBLE TEES have proven to be the material of choice for:

Parking decks
Water/Wastewater Treatment Plants
Food Processing Plants
Heavy Industrial buildings
Warehouses
Arenas, Indoor Pools and Gymnasiums.

Consider double tees for those longer spans and heavier loads that exceed the capacity of hollowcore plank. Double tees have evolved from 1220mm (4′-0′) widths to 2440mm (8′-0′), 3000mm (10′-0′) and 3660mm (12′-0′). Depths can vary from 300mm to 900mm. Spans can range from 10 to 25m for floor loads to over 33m for roofs. Double tee dimensions are based on many factors (design efficiency, most popular usage, fire regulations, transportation regulations).
