Conform composite decking is ideal for floor slab
construction in residential, commercial and many industrial
It is suitable for use in both steel frame and concrete frame
construction, including band beam applications. In addition,
Conform composite decking has been successfully used in post-tensioned
Whilst generally used in composite construction, Conform decking
can be used as an effective lost formwork in conventional
Conform composite decking is only indented for use in composite
or non-composite suspended floor slab applications and strictly
as shown in this and other current Stramit technical literature.
Do not use for any other purpose.
Conform decking is generally offered in three standard base
metal thicknesses of 0.75mm, 1.0mm. Other thicknesses may
be supplied, dependent on lead times and availability. Conform
end span accessory is generally offered in 1.0mm base metal
Conform decking is manufactured from high-tensile steel with
a Z350/Z450 galvanised coating, in full conformance with AS1397.
Maintaining the correct specification of composite decking
is important to ensure that all design requirements are met
- The concrete formwork shall be 0.75 (or 1.00) mm
thick Conform decking to 55mm high ribs spaced at
300mm centres. Material shall be G550 high-tensile
steel in accordance with AS1397, with a Z350/Z450
- Individual sheets shall be hinged into position
in accordance with the manufacturer’s instructions.
- Prior to concrete pouring, foot traffic and other
construction loads being applied, the Conform decking
shall be propped in accordance with our specifications.
- Reinforcement and concrete placement shall be as
directed by the engineer.
- All work is to be completed in a workmanlike manner
and all dirt, mud, debris, screws, rivets, cutting,
etc are to be removed prior to concrete pouring. Props
are not to be removed until authorised by the site
Conform decking has excellent durability. However, in applications
close to marine or severe industrial environments, or closer
than 450mm to the ground, please contact us for a more detailed
assessment of your needs, and for guidance on any precautions
that may be required.
Direct contact between galvanised steel and copper, or water
run-off from copper onto galvanised steel must be avoided,
as premature corrosion will result.
In the construction phase, the effective span is the lesser
distance between permanent supports and clear span +55mm.
A single span has two permanent supports. A double span has
three permanent supports. Continuous spans have four permanent
