FEATURE
LCP LYCORDECK® (formerly known as CONDECK® HP)
Steel Decking is designed to be used in composite
construction and save reinforcing material and
construction time.
All relevant and latest Eurocodes were used to ensure
that the LCP LYCORDECK® Steel Decking performs at the
highest level in accordance with the latest Singapore
requirements.
INTRODUCING UPDATED LCP LYCORDECK® STEEL DECKING
LCP LYCORDECK® will still feature:
With a constant need to keep abreast of international
standards to meet industry needs and building
authority requirements, LCPBP has engaged a local
academic institution to conduct full-scale tests to
ascertain that its design adheres to the Eurocodes.
Hence, with this update, we launch the steel decking
as LCPoLYCORDECK® to keep in line with our brand of
building products trusted by many of our clients.
Superior span performance – for greater span
capacity.
The steel decking will still retain the advantages derived
from its unique characteristics, i.e. the closed rib profile,
which sets it apart from its competitors.
Improved fire resistance periods – for even more cost
effective slabs.
Substantially reduced side lap fasteners – reduced
installation time.
Facility for ceiling system suspension – for quicker
ceiling installation if required.

ENHANCED SPANNING
The exclusive LCP LYCORDECK® (Super) 3rd Rib
accessory, developed by LCPBP, is fastened along the
side of the end span ribs to significantly reduce end
span deflection under wet concrete. This effectively
eliminates the design limits imposed by end spans.
LCPoLYCORDECK® (Super) 3rd Rib accessory can be
used to increase unpropped end spans.
SUPER 3rd RIB
LCP LYCORDECK® (Super) 3rd Rib accessory increases the
spanning performance of LCP LYCORDECK® composite
decking in several ways.
Besides reducing lateral rib distortion and tray deflection,
it increases the stiffness of the composite slab and
increases the deck spans. With greater deck spans
come a reduction in the amount of propping required.
This accessory is simple to install and is only required on
decking end spans.
TESTING PROGRAMME
Design data for LCP LYCORDECK® composite decking are based on thorough testing
of performance in formwork, composite and fire design modes.
Full-scale and pilot tests were carried out by the School of Civil and Environmental
Engineering (CEE), Nanyang Technological University (NTU) and Building Research
Association of New Zealand (BRANZ).
The tests conducted on LCP LYCORDECK® with reference to Eurocode 4 include:
Shear and bending resistance of LCP LYCORDECK® at ambient temperature.
An experimental study of heat transfer through LCP LYCORDECK® composite
slabs to evaluate temperature distributions across the thickness of the slab.
LCP LYCORDECK® composite slab under loading in fire situation.

KEY ADVANTAGES AT DIFFERENT STAGES
Construction stage
Ease of installation
Labour savings during installation
Time savings during installation
No need for rib-end closures
Composite stage
Reduced steel reinforcement
Resistance to deflection
Flexible placement of shear studs
Maintains sound and vibration insulation
Fire Emergency stage
Embedded ribs act as Fire Emergency Reinforcement
(F.E.R.)
Unrestricted placement of fire reinforcement
ADVANTAGES IN CONSTRUCTION STAGE
Ease of installation
The 300mm sheet width of LCP LYCORDECK® composite
decking makes it easy to carry, simple to cut and
trim and easier to fit to the floor layout with minimal
wastage. Its light weight allows two people to carry long
continuous lengths. Once in place the wide pan is easy
and safe to walk in.
Labour savings
LCP LYCORDECK® decking requires no timber formworks
and can be installed by semi-skilled labour under
supervision. The wide trays allow easy installation of
penetrations.
Time savings
The characteristic sheet interlocking of LCP LYCORDECK®
composite decking ensures quick, cost-effective
installation. The only fastening to attach the sheet to
the structure is minimal. Side lap fasteners are often not
required to connect the interlocking sheets.
No need for rib-end closures
The closed ribs of the LCPoLYCORDECK® does not require rib end closures or taping of joints therefore lowering installation
time and costs.

L Y C O R D E C K®
ADVANTAGES IN COMPOSITE STAGE
Reduced steel reinforcement
Generally, conventional positive reinforcement is not
required. LCP LYCORDECK® composite decking acts as
positive reinforcement to optimize strength and control
composite slab deflection.
Negative reinforcement may be reduced in many
continuous slabs by applying the partial shear
connection strength factor to take account of moment
redistribution
Resistance to deflection
Deflection of the completed composite slab is often the
governing design criterion. LCP LYCORDECK® composite
decking has excellent resistance to deflection due to
its ribs being fully enclosed in the concrete slab. The ribs
are embedded in the slab to provide maximum stiffness.
Flexible placement of shear studs
There are effectively no restrictions on the placement
of shear studs with LCP LYCORDECK® composite slab.
Therefore, flexibility in beam design provide engineers
with the opportunity to reduce the size of I-beams by
up to 20%.
Design virtually any stud configuration with 100mm,
200mm or 300mm centres.
10 stud/metre (single row) - nominal 100mm spacing
Maintains sound and vibration insulation
The LCP LYCORDECK® composite slab does not
compromise on sound insulation and vibration as it
is similar to a solid slab with the ribs being completely
encased in concrete with no voids.

L C P
L Y C O R D E C K®
ADVANTAGES IN FIRE EMERGENCY STAGE
Embedded ribs act as Fire Emergency Reinforcement (F.E.R.)
LCP LYCORDECK® composite decking has all of its profile
ribs embedded in finished concrete slab giving thermal
insulation comparable to a solid slab.
Compared with trapezoidal and re-entrant decks, there
are no gaps at the soffit of the slab for heat to penetrate.
This allows the ribs to remain cool and act as FER.
Based on the simplified FER design method for
LCPoLYCORDECK® composite decking, minimal or even
no additional reinforcement may be required.
Concrete
Unrestricted Placement of F.E.R.
Since the ribs of LCP LYCORDECK® are embedded in the
concrete, F.E.R. may be placed anywhere above the
ribs unlike trapezoidal or re-entrant decks where F.E.R.
placement is limited.

The flat base of LCP LYCORDECK is aesthetically
pleasing and if required, fireproofing or painting

heights to suit different slab depths. The top
flange of the Edgeforma should be tied back to
LCPoLYCORDECK® steel decking ribs every 600mm
with galvanised strapping. For unsupported

LCP LYCORDECK® steel decking has provision for
suspended ceiling installation or support of building
services. A two part bracket is simply inserted into
the underside of any rib and held in place by the
suspension rod. The ceiling hanger is capable of
supporting a load of 2.5kN after the concrete is in
place.
Note: Side lap fasteners, installed through the vertical
web of the ribs - at no more than 500mm centers either
side of the hanger, are required if ceiling hanger is loaded
before the concrete pour. In this case, the maximum
capacity of the hanger is reduced to 0.6kN.
