  • KF70® effectively saves 26mm of concrete off the overall slab depth by concrete volume when compared to conventional concrete slabs
     

RF55®

The Fielders KingFlor® RF55® excels in structural performance due to the patented ReLok® corner embossments that create a mechanical interlock with concrete slabs.  It is a traditional re-entrant profile that provides unmatched performance in suspended concrete slabs. It also possess dovetail lapping ribs which resist lateral deflection to enhance the profile’s spanning capacity and strength in positive bending and end shear.

Advantages of RF55®: 

  • RF55® comes complete with a range of accessories allowing for easy suspension of ceilings and services
  • Stronger composite strength: RF55® is stronger than similar decks due to the patented ReLok corner embossments. ReLok develops a strong mechanical interlock with the concrete slab
  • Greater spanning capacities: RF55® is stronger than similar decks in positive bending and end shear due to the dovetail ribs which resist lateral deflection 
  • RF55® is available in two sheet widths. The traditional 600mm wide cover, 3 pan (3p), and easy to handle, 400mm wide cover, 2 pan (2p)
  • The RF55® -2P is equivalent in all aspects technically to the RF55® -3P. Similarly, the recommendations for RF55® in construction also apply to both RF55® -3P and RF55® -2P
     

KF57®

Fielders KingFlor® KF57® offers builders a steel formwork for composite concrete slabs that is light weight and easy to use, making this the perfect solution for concrete and steel framed construction. This excellent ‘steel decking’ product was designed to combine effectively and harmoniously with a concrete slab and once laid becomes a permanent part of the slab, therefore eliminating formwork stripping.

The major benefits of the KF57® product are its unique profile with wide pans that allow clear access for in-floor services, minimal propping and easy access to the underside of the slab. Designed to be able to achieve high fire ratings it is ideal for many applications, retail projects in particular, as the closed rib profile is completely imbedded in the slab offering a major reduction in fire reinforcement.

Advantages of KF57®:

  • Permanent composite formwork system: Once laid, KF57® becomes a permanent part of the slab, eliminating the need for formwork stripping
  • Unique profile: Wide pans allow for clear access for in-floor services
  • Minimal propping: Less propping congestion and easy access to the underside of the slab
  • Supplied pre-cut to length, with 300mm wide cover: Quick to install
  • Reinforcing mesh can be laid directly on to the ribs: In many applications there is no need for mesh support stools
  • Closed rib profile, fully embedded in concrete slab: Major reduction in fire reinforcement 
     

PT Plus™ Design Solutions

Post-tensioned, concrete-framed construction utilising metal formwork for the floor slab has proven to be one of the most popular and cost-effective construction methods for buildings in Australia. Utilising post-tensioning, composite metal decking floor with band beam supports, structural engineers are able to design longer spanning floors and optimise the spacing of the columns. Further cost savings are obtained from the metal decking acting as formwork requiring less temporary propping and labour costs, as well as increased speed of construction for the floors due to the metal deck being a permanent fixture.

Fielders are able to assist structural design engineers in incorporating a PT-PLUS solution to their project, utlising the KingFlor® profile as the main tensile reinforcement in the direction of the sheeting leading to more efficient and economical slab designs. The development of PT-Plus creates a completely new set of rules to assist with the design of one-way, post-tensioned composite slabs that incorporating Fielders’ KingFlor® composite steel formwork profiles and bonded pre-stressing strands as tensile reinforcement in the slab bottom face. The inclusion of the steel decking as bottom tensile reinforcement can provide significant savings without the need for additional prestress or additional conventional bottom bar reinforcement.

SlimFlor®

Fielders SlimFlor® utilises Fielders SlimDek 210™ flooring profile in conjunction with Asymmetric Steel Beam Sections (ASB) to provide a floor system with a reduced construction zone. It does this by combining the floor slab and supporting structure in the same plane, providing a lightweight, versatile, long spanning floor system.

Advantages of SlimFlor®: 

  • Reduced construction time (saving in labour, early tenancy and associated works, approximately 20% quicker floor-to-floor construction time)
  • Minimal temporary propping allows for fit out of lower floors while upper floors are being constructed
  • Shallow floor depths, reduced overall building height offers savings in façade costs and building height restrictions
  • Reduced trades onsite (OH&S savings)
  • Light weight structure, reducing sizes of substructure and footings
  • Ease of service integration, with potential to accommodate the services within the slab depth
  • Inherent fire resistance. A fire resistance of 60 minutes can be achieved without fire protection
