Floor deck systems are commonly used in the construction industry to create floors for buildings. They serve as a base for concrete slab construction, providing structural support and a platform for workers to carry out their tasks. Among the different types of floor deck systems available, closed and open floor decks are two of the most popular choices. In this article, we will take a closer look at these two systems, and explore their differences.
Open Floor Deck System
An open floor deck system is also known as a “profiled” deck. It is designed with a ribbed profile on the surface, which creates a series of channels between the ribs. These channels provide a path for concrete to flow and fill up the spaces between the ribs during the concrete pour. The channels also help to reduce the weight of the deck, making it a popular choice for multi-story buildings.
Open floor deck systems are relatively easy to install and require less structural steel than closed floor decks. They are also suitable for use in buildings with low load requirements. However, open floor decks have some drawbacks. They are less fire-resistant than closed floor decks and have a higher risk of corrosion due to the exposed steel.
Closed Floor Deck System
A closed floor deck system, on the other hand, is designed with a flat surface on the top and bottom. It does not have any channels or openings, and the concrete is poured directly onto the surface of the deck. This makes it more fire-resistant than open floor decks and reduces the risk of corrosion since the steel is not exposed.
Closed floor decks are generally more expensive to install than open floor decks, as they require more structural steel. However, they are more suitable for buildings with high load requirements, as they offer better structural support. Closed floor decks are also easier to maintain, as they require less upkeep and have a longer lifespan.
Key Differences between Closed and Open Floor Deck Systems
1.Structural Support: Closed floor deck systems offer better structural support than open floor deck systems. They are designed to bear heavier loads and are more suitable for use in multi-story buildings.
2.Fire Resistance: Closed floor deck systems are more fire-resistant than open floor deck systems. This is because the flat surface of the closed deck does not provide channels for fire to spread, whereas the channels in open floor decks can provide a path for fire to spread.
3.Corrosion Resistance: Closed floor deck systems are less prone to corrosion than open floor deck systems. This is because the steel in closed decks is not exposed to the elements, whereas the steel in open decks is exposed, making it more vulnerable to corrosion.
4.Cost: Closed floor deck systems are generally more expensive to install than open floor deck systems, as they require more structural steel. However, closed floor decks offer better structural support and have a longer lifespan, which can offset the initial cost.
Conclusion
Choosing the right floor deck system is an important decision that can have a significant impact on the safety, durability, and cost-effectiveness of a building. Closed and open floor deck systems are two of the most popular choices available, and each system has its own advantages and disadvantages. By understanding the differences between these two systems, builders can make an informed decision that meets the specific needs of their project.
