Hibond 80 is the deepest flooring profile allowing longer un-propped spans, minimises beam layout. Designed in accordance with the procedures and limit states in AS/NZS 2327 based on detailed analysis by the Heavy Engineering Research Association (HERA) and comprehensive physical testing.
Materials and Components
Hibond 80 is roll-formed from high strength zinc-coated steel coil to AS1397, available in 0.75mm, 0.95mm. 1.05mm and 1.15mm thicknesses. Hibond 80 is supplied with a range compatible components including End Caps, Edge Form and Rake Cut Edge Flashings.
Dimond Hibond 80 and accessories are manufactured from galvanised steel coil produced to AS 1397.
BMT - Base Metal Thickness
Length: -0mm +10mm
Cover width: -1mm +5mm
Maximum manufactured length of Hibond 80 sheet: 15m
Manufactured from 1.15mm Base Metal Thickness (BMT) galvanised steel in 6m lengths, providing an edge to screed the concrete to the correct composite floor slab thickness.
Standard sizes are from 150mm to 230mm in 10mm height increments.
The foot of the Edge Form is typically fixed to a structure using powder-actuated fasteners (self-drilling screws can also be used, type dependent on support material and thickness).
Where necessary, for example, cantilevered steel decking sheets, the foot of the Edge Form may be attached to the Hibond 80 sheets with 10g - 16 x 16mm self-drilling screws. Fasteners are required every pan to steel decking sheet ends and at 750mm centres along the steel decking sheets.
Edge Form Support Strap
Edge Form is restrained from outward movement during concrete placement by 0.75mm BMT x 25mm galvanised steel Edge Form Support Straps. Fastened with 10g - 16 x 16mm self-drilling screws (2 per strap), Edge Form Support Straps are required every second rib to steel decking sheet ends and at 750mm centres along the steel decking sheets.
Manufactured from 0.55mm BMT galvanised steel, end caps are used to blank off the ribs (to prevent concrete leakage) at the end of each Hibond 80 sheet, or where openings are created in the deck. Each End Cap is fixed to the Hibond 80 sheet with 1 fastener atop each rib (10g - 16 x 16mm self-drilling screw).
Rake Cut Edge Flashings
Manufactured from 0.55mm BMT galvanised steel in 95mm x 30mm x 3m lengths which are cut to suit on-site (as shown).
Rake cut edge flashings are used in place of end caps to close off the end of Hibond 80 sheets when they are cut on an angle or curve. These are cut to length and fixed to the Hibond 80 sheet with 1 fastener atop each rib (10g - 16 x 16mm self-drilling screw).
The Hibond 80 flooring system must be designed in accordance with the procedures and limit states specified in AS/NZS 2327:2017 with Hibond 80 as formwork for concrete placement, incorporating the requirements, limitations and information given in the Flooring Design manual.
Compliance is based on detailed analysis by the Heavy Engineering Research Association (HERA) and comprehensive physical testing, enabling load/span capacities to be established for actions, load combinations and performance limitations in accordance with AS/NZS 2327:2017, based on the Hibond 80 steel decking sheet achieving partial shear connection, for
- Ultimate Limit State Capacity Factors to AS/NZS 1170.
- Serviceability Limit State deflection, vibration and cracking control.
- Hibond 80 performance testing was carried out by :
- Imperial College London - structural tests to EN 1993-1-3 and EN 1994-1-1
- Exova Warringtonfire - fire resistance tests to EN 1365-2
- University of Auckland
- Welded shear stud capacity.
- Structural tests to AS/NZS 2327:2017
Data presented in Flooring Design manual is intended for use by qualified structural engineers. Use of Hibond 80 in applications outside the scope of this manual will require specific structural design from first principles.
A minimum 28-day compressive strength of 25MPa for high-grade concrete has been assumed.
The self-weight of the Hibond 80 Flooring System (including the concrete) has been included in the load tables.
