Features and Pros & Cons

Sectional diagram
Structural detail
Reduction of construction time
  • Reduces construction time compared to existing deck plates because its installation is simplified by using 2 spans continuously and because of dust sleeve reinforcement work, the wiring system, and flexible piping work.
  • Since the bottom plate is flat, ceiling finishing work is simple. Additionally, HI-DECK II has outstanding sound- and vibration-proof characteristics. It is ideal for an apartment application which requires flexible spaces.
Safety
  • Since an upper triangle-shaped rib is buried in concrete, it serves as a connector between the bottom plate and concrete. When concrete is poured, HI-DECK II holds its shape to form a strong slab able to withstand extreme conditions such as earthquakes or fire.
Economical
  • Since the possible thickness varies (0.8mm, Over 1.0mm, Over 1.2mm, Over 1.4mm, Over 1.6mm), HI-DECK II offers some economic benefits. The flat bottom reduces the bottom of the slab so that it reduces the story height. Therefore, it is ideal for high-rise buildings.
  • HI-DECK II can reduce about Under 4.3% of the amount of concrete due to a 10mm camber and a triangle-shaped rib when the thickness of the slab is 12cm. The wire mesh on the upper part of the slab minimizes the use of additional reinforced rods.
Sectional Performance
  • HI-DECK II is widely used for both low- and high-rise buildings. It can be used in under- and above-ground applications as well as for building factories and bridges that use reinforced concrete, steel frames, and steel-reinforced concrete. It is especially appropriate for building steel frame skyscrapers.
