Ledex® Mega Floor Deck

Description

  • Ledex® Mega Floor Deck is the next generation composite steel deck that combines the tensile strength of steel with compressive strength of concrete. This is to improve design efficiency with minimal use of concrete. Hence, this enables a new benchmark for more shallow and concrete slab construction.
  • Ledex® Mega Floor Deck has a structurally efficient ribbed profile that provides an excellent interlock between steel and concrete. This creates a positive reinforcement to maximise load capacity. the efficient shape of the deck is an ideal choice for composite slab construction.
  • Ledex® Mega Floor Deck increases the speed of floor construction and provides a safe working platform to enable low interruption during construction. It requires low maintenance and gives lightweight building a longer life span.

Application

  • Multi Stories Buildings
  • Mezzanines Floor
  • Bridge Walkways
  • Car Porches
  • Parking Garages
  • Warehouse

Advantages

1. Low Material Cost

Ledex® Mega Floor Deck’s composite has high strength to weight ratio. The lighter weight composite material reduces the steel works frame weight and the ribbed profile shape reduces the concrete volume. As a result, delivery, erection and structural framing costs can be lower. This not only use as formwork purpose but also serve as wide working platform thus decrease the period of construction.

2. Reduce Construction Time and Cost

Ledex® Mega Floor Deck can be easily cut, joined and fitted to any required shapes. Laying and reinforcing the deck are combined to a single stage. The low weight deck can be laid by hand and not by crane. Shorter construction stages and reduced dependency of heavy machines helps to speed up construction time. Since there is no wooden formwork support needed, it produces no assembly waste.

3. Improved Quality and Reliability

Ledex® Mega Floor Deck offers excellent quality through engineering and continuously refined production techniques. The long sustainability of steel can offer low maintenance cost over time.

Ledex® Mega Floor Deck

  • Increase construction speed and less workers required to complete the same construction
  • Construction can be completed in a shorter time in any different floors at a same time.
  • No need to consider for formwork removal prematurely without affecting template.
  • Less floor crack seepage happening because better floor quality
  • Do not need formwork support. Consecutive floor level can be carried out immediately.
  • Reduce the accumulation of material on-site (Reduce wooden materials stacking on job site), work safety and good health.

Traditional Wooden Mould

  • Construction is slow and more workers required to complete the same construction
  • Construction cannot be completed in a shorter time in any different floors at a same time.
  • Need to consider for formwork removal prematurely, the floor easier to crack, and have seepage.
  • The working platform can be dispensed with and the need of crane for internal transport maybe reduce significantly.
  • Increase the accumulation of material on-site (Increase wooden materials stacking on job site, site dirty, prone to danger)
