Double T slabs
Modern Concrete Company
Known as double tees or TT slabs, are precast/prestressed concrete elements widely used in construction for spanning long distances and supporting heavy loads. They resemble two T-beams connected side by side, with a wide flange on top and two vertical webs (stems) on the bottom.
Here are some key features and benefits of double T slabs:
- Long spans: Double T slabs can achieve spans of up to 29 meters or more, eliminating the need for intermediate supports and creating open, column-free spaces.
- High load capacity: The T-shaped cross-section efficiently distributes loads, making them suitable for heavy-duty applications like parking garages, industrial buildings, and stadiums.
- Fast and efficient construction: Double T slabs are precast in factories, allowing for faster installation compared to traditional cast-in-place concrete slabs. This reduces construction time and labor costs.
- Durable and low maintenance: Prestressed concrete used in double T slabs is strong and resistant to cracking and corrosion, requiring minimal maintenance over the years.
- Versatile applications: Double T slabs can be used in various building types, including floors, roofs, decks, and bridges. They can also be customized with different finishes and textures to suit specific aesthetic requirements.
- Higher initial cost: The prefabrication process and transportation costs can make double T slabs more expensive than cast-in-place concrete initially.
In Modern Concrete we have a unique mold from ELEMATIC for production of TT slabs equipped with heating system for concrete curing, and our production is done under a strict quality control procedures starting from design through all production stages.
Overall, double T slabs are a valuable construction material for projects requiring long spans, high load capacity, and fast construction. However, it’s important to consider their limitations and weigh them against the project’s specific requirements and budget.
