LYSAGHT LOCKED SEAM
1) PRODUCT PROFILE
LYSAGHT LOCKED SEAM is a
high quality lightweight engineered
standing seam roof for use as fully
supported roong and walling
cladding in curved, pitched and
tapered condition. LYSAGHTLOCKED SEAM prole offers
qualities of economy and durability,
which are adapted to contemporary
architecture.
LYSAGHTLOCKED SEAMoffers:Water tightness - Excellent water
tightness for areas with high rainfall
intensity and can be designed to
with stand high wind conditions.
Discreet - At 32mm, the specially
designed height of the standing
seam contributes to the modernity,
lightness and regularity of the
roong in its architectural function;
particulary when used on morecomplex shapes, giving them a
distinctive high-tech appearance.

LYSAGHT LOCKED SEAM
LYSAGHT LOCKED SEAM
comprises of metal trays mechanically
seamed during installation, folding
the panel edges 180 or 360 degrees
to form an angled or double seam
producing structurally strong and
rainproof joints.
This exclusive seaming process
integrates both moving and
non-moving clips into the seam to
accommodate expansion and
contraction of the roof panels.
LYSAGHT LOCKED SEAM is
based on metal trays roll form in
the factory, or on site in a controlled
environment.
The panels require a solid substrate
such as LYSAGHT SPANDEK or
LYSAGHT TRIMDEK Alternatively,
it can be supported on rigid
insulation such as rockwool.

Fastening Method of LYSAGHT
LOCKED SEAM
LYSAGHT LOCKED SEAM
panel is designed to be suitable for
fastening onto a solid substrate, a
corrugated prole, structural
decking or plywood. Concealed
clips are integrated into thestanding seam rib.
The anchorage and the method
of fastening are crucial factors in
the xing of the roof skin to the
substructures. All forces arising from
the wind pressure must be safely
directed from the roof skin via all
other building components into the
anchorage. The suction forces
applicable to a roof are inuenced
by the roof shape as well as height
and position of the building. Peaksuction will occur at the exposed
roof edge and overhanging area.
Fastening Method for High Wind &
Cyclonic load
LYSAGHT LOCKED SEAM can
be designed and congured to
withstand High Wind Pressure and
Cyclonic load. The test has been
carried out in accordance with:
Structural Adequacy Test underStatic Pressure to ASTM E330 and
Structural Adequacy Test under BD
PNAP 106 Cyclic
Tests and simulation were conducted
in a specially designed prefabricated
steel chamber that is HOKLAS
(Hong Kong Laboratory Accreditation
Scheme) Accredited.
Reg. No. HOKLAS 110.
Please contact BlueScope Lysaght
for details on cover width, thicknessand design load application for
LYSAGHT LOCKED SEAM panel.
The design calculation and wind
load analysis of the xing
methodology has been specially
designed by BlueScope Lysaght

department and veried by the
National University of Singapore,
Department of Civil Engineering.
ACOUSTIC ROOF SYSTEM
As a result of laboratory measurement of airborne sound transmission loss of BlueScope Lysaght Acoustic Roof System,
Spring Singapore (Acoustic Test Laboratory) had rated the roof system tested on October 10, 2002 as having a sound
transmission class 51 (STC 51). The test was conducted in accordance with ASTM E90 97.

Quartz Zinc is pre-weathered zinc
whose light grey colour is similar to
that of the light grey of natural patina
upon installation. Quartz Zinc offers a
uniform and homogenous patina and
colour from the moment of fabrication.
Its patina remains absolutely stable
over time and is perfectly environmentally
friendly.
This unique process of pre-weathering
on Zinc leads to a more uniform
appearance and gives the roof and
the cladding the gloss and colour of
the natural patina of natural Zinc from
the moment it is installed.

OIL CANNING
Whether a metal will appear at or
not depends on the distribution of
the stresses across its surface. These
stresses will change as temperature
changes. The ability of a metal to
transfer the effect of these stresses
across the surface without buckling or
distorting out of plan, will determine
the level of oil canning that will
occur.
Oil canning is a metaphorical term
used to describe the tendency of at
surfaces to show variations in
reectivity. For example, a curved
mirror will show a stretched and
distorted image of a person standing
in front of it. So too will a metal
surface distort the reection of light if
minor variations in and out of a levelplane exist. The appearance of atness
is very much dependent on surface
reectivity. It is also caused by mill
tolerances, variations in the substrate/
decking and purlin alignment. Some
paint nishes and metals that have
high gloss index will exhibit highly
apparent distortion. The visual effects
of oil canning can be exacerbated by
different light conditions and
orientation. Darker colours visually
accentuate oil canning to a greater
extent than the lighter, more neutralcolours.
There are several precautions that can
be taken to reduce the oil canning
effect. One is to use thicker material,
because thicker metal tends to oil-can
less than thinner metal. An alternative
is to specify for LYSAGHT LOCKED
SEAM trays with stiffening ribs in the
pan of the panels.
Oil canning is an inherent characteristic
and not a defect of a standing seamprole. It is therefore not a cause for
panel rejection.
3. ZINC TITANIUM
Zinc titanium is a metal consisting
of Pure Zinc (99.99%) alloyed with
a small quantity of titanium and
copper. It corresponds to the Z1
classication that is the highest
quality of Zinc titanium in the
European Standard EN1179
Zinc Titanium is produced to conform
to European Norms EN 988 and
EN1179. EN1179: regulates the
classication of the alloy elements.
EN988: controls the nishes and
tolerances of the rolled products.
The metallic zinc surfaces react with
the main constituents of the
atmosphere like oxygen, carbon
dioxide and hydrogen to build a
supercial patina. This layer is
compact, adherent and insoluble inrainwater and will hinder any further
exchange between oxygen and zinc
thereby maintaining a very low
corrosion rate of rolled zinc.
The buildup of natural zinc patina
takes time and environmental
conditions.
VM Zinc has developed a chemical
process by which the external surface
of the natural zinc can be modied
in chemical bath: the pre-weather-
ing process is carried out on naturalzinc as per NFA55-201, NFA55-211,
DIN17770 or BS6561 and is therefore
neither a paint or a coating resulting
from any colour coating, spraying or
brush painting process.
The factory controlled pre-weathered
surface is similar to the patina formed
by natural zinc after a few years of
ex-posure to the atmosphere.
The name given to this pre-weathered
zinc is called: Quartz Zinc.
