BlueDeck is a rigid permanent metal decking formwork for simplifying the construction of suspended concrete slabs.
It’s made from high-tensile steel offering high spanning capabilities. The durable galvanised finish creates a neat & clean, low maintenance ceiling finish.
BlueDeck comes with a signature blue anti-glare coating that’ll reduce heat & glare off the deck during the warmer months.
BlueDeck is ideal for carparks, office buildings, hospitals and deep beam style slabs.
INTRODUCTION
CUSTOM LENGTHS
Z350 IN CONFORMANCE WITH AS1397 GALVANISED ZINC COATING
ANTI-GLARE COATING
High Tensile steel: Excellent spanning capacity and cantilever strength.
Light weight: 0.75mm 3.1kg/Lm and 1.0mm 4kg/lm, easy to handle.
Soffit Finish: No voids to fill, clean neat ceiling finish.
Installation: Clips together, fast efficient, snug fit joint.
Fire Rating: BlueDeck achieves a 2hour fire rating with a fully cured concrete slab as per the fire resistance table on page 6. The BlueDeck contains no open ribs and retains the majority of its strength over that period.
Anti-Glare Coating: Blue waterbased film, non-toxic or hazardous coating reduces glare by up to 82% and does not compromise the composite slab performance.

1. Fire Resistance Period
Any composite slab must be designed to achieve a fire resistance period (FRP) for structural adequacy, integrity and insulation of not less than the required fire resistance level (FRL) as specified in The National Construction Code – Building Code of Australia (NCC-BCA)
Chart shows FRP for insulation of various slab thicknesses constructed using BlueDeck. The FRP has been calculated in accordance with Australian Standards: Composite Structures, AS 2327-2017 EN Combined, Clause 7.7.2.2 – Insulation for composite slabs, and modified taking into account.

1. Propping and Supports
If temporary propping is required, it must be fitted before BlueDeck installation and be perpendicular to the length of the sheets being installed, where the span becomes greater than the dimensions on the un-propped span charts
Prop width to be 100mm or greater and must be in accordance with AS3610 and the site engineers’ requirements.
Refer to the span tables for all propping information.
Structural/Permanent deck supports to be minimum 100mm bearing.
2. Deck Installation
BlueDeck installation is very simple and fast. Starting from one side with the correct sheet orientation (RIBS facing away from install path) hook the next deck over the previous placed end rib and drop to the support structure. The tight locking action of the profile provides a near waterproof joint.
Continuous over single slab span
Equal formwork spans
3. Deck Fixings
Securing of the BlueDeck must follow immediately after placement of each section to prevent any uplift caused by wind.
Minimum requirements:
• 1 fixing in each end of every deck into a permanent structure
• 1 fixing into every second pan, at every permanent support location
• Fix approx. 30mm from the rib
Fixings: use powder actuated fixings or self-drilling screws into permanent supports as the substrate requires.
4. Edge Formwork
Install Edgeform to edges that require formwork and use strap ties at approx. 900 centers to secure back to the pan using self-drilling screws provided.
Edgeform is fitted by sliding under the BlueDeck and screw fixing
Edgeform
5. Slab Reinforcement
Once deck is secure and all edge forms installed, place reinforcement to engineers’ requirements specific to that slab.
6. Concrete Placement
Ensure that the deck is clean of any debris, preferably blown down with powered blower and free of any grease or oils that would prevent concrete adhesion.
Concrete to be poured evenly across the deck and mounding of wet concrete in a concentrated zone must be avoided at all times.

The spanning tables presented in this Section are based on the following assumptions and constraints. The reader needs to ensure that the particular situation being designed falls within these assumptions and constraints.
1. These tables can be used for different types of construction (steel-frame, concrete-frame, masonry wall supports) provided BlueDeck sheets are securely fixed to all permanent and temporary supports at every pan.
• Suitable secure fixing methods should be used such as spot welds, self-drilling screws or drive nails.
• Temporary props are equally spaced within each slab span.
• There are 2 formwork tables for 0.75mm and 1.0mm material.
• Ratio of two adjacent slab spans equal 1:1, that is I/L=1
• The ratio of the longer slab span (L,) to the shorter slab span (L5) does not exceed 1.2, that is I1 / L5 ≤ 1.2
2. The tables shall be used for normal density concrete (2400 kg/m3).
3. The lines of support shall extend across the full width of the sheeting and have a minimum bearing 100 mm at the ends of the sheets and 100 mm at intermediate supports over which sheeting is continuous, including at props. 50 mm minimum bearing length at the ends of sheets is acceptable in concrete frame construction.
4. The tables are based on the following maximum construction loads:
• Workmen and equipment = 100 kg/m2
• Mounting of concrete = 300 kg/m2 over an area of 1.6 x 1.6 m and zero over the remainder.
• Stacking of material on BlueDeck sheets before placement of concrete only = 100 kg/m2. This load shall be clearly indicated on the formwork documentation and controlled on-site.
5. Tables developed based on maximum BlueDeck length is 19,500 mm (check availability of local lengths.) - To be confirmed by the manufacturer.
6. No loads from stacked materials are allowed until the concrete has set.
7. The sheets shall not be spliced or jointed.
8. Allowance for the weight of reinforcement as well as the effect of ponding has been taken into account.
9. Supports shall be effectively rigid and strong to support construction loads.
10. The sheeting shall not have cantilever portions.
11. Wet concrete deflection of BlueDeck = 1/240 or 1/130, where the distance between centres of props or permanent supports.
12. The information contained in the publication is intended for guidance only. This information to be used only in conjunction with a consulting structural engineer.
13. Further details can be sought from the FTI Group.
1. Use of span tables
SPAN TABLES
2. Span Tables
Maximum slab spans, mm
BlueDeck sheets continuous over single slab span
Formwork deflections limit L/240 (Visual appearance important)
1. These are formwork selection tables only. Maximum slab spans in these tables shall be designed by a qualified structural engineer.
2. Prop must be equally spaced between the span and prop bearers & support widths should be minimum 100mm.
3. 1 kPa Live Load due to stacked materials is used – this shall be indicated on formwork documentation and controlled on-site.
4. Refer to General Engineering Notes Section 3.1 when using these tables.
5. Care must be exercised when placing concrete to avoid excessive mounding.
6. Spreaders shall be provided to prevent any concentrated loads being applied to the sheeting, in particular, avoiding direct point loading of the sheet overlap ribs and unsupported edges of the sheeting.
7. When using the table for two or more spans the adjacent spans should not differ in length by more than 5%.
8. *300/*350 slab should be designed under the typical reinforced slab AS 3600-2009 by a qualified structural engineer.
