SPEEDFLOOR, the unique suspended concrete flooring system, is an innovation in the building industry. So quick and easy to install, SPEEDFLOOR is a lightweight, cost-effective system that's perfect for multi-storey buildings and carparks. Whether it's one storey or fifteen, the recipe is very simple. take sufficient quantity of SPEEDFLOOR, add structural steel or concrete supports, mix concrete and pourlAt the heart of the system is a specially rollformed, galvanised steel joist that offers all the benefits of an open-webbed truss system at a more enough to be man- handled into place, reducing cranaage costs. Services are easily accommodated through the joists which are delivered to the site ready to install. SPEEDFLOOR The perfectly simple, simply perfect solution to multi-storey construction.

SUPPORT
1
The individually marked,
lightweight rollformed
steel joists are easily lifted
into place on the support
medium.
3
Lockbars are placed
approximately 300mm
apart to give the
plywood good support.
2
Lockbars, which will
support the plywood
shuttering, are slid into
the slots punched in the
top section of the joist and
by engaging the notches
at both ends of the lock
bar, the exact spacing of
the joist is secure.
4
The plywood is introduced
from the top and is held in
position by the cam action
of the lockbars. A working
platform from which the
rest of the plywood can be
laid is quickly progressed
down the building
6
The finished floor after the
lock bars and plywood are
removed reveals the
concrete soffit and exposed
joist where services can be
passed through pre-
punched holes. The bottom
of the joist can support a
suspended fire rated ceiling
directly fixed to the joist.
5
The mesh is laid out and
tied into place. No stools
are required as it is held
off the deck by the top
section of the joist, which
becomes embedded in the
concrete and will gain
composite action once the
concrete is cured.
Easy to install
Our name says it all.
