Product description
• Lightweight purlin systems
make building fast and
easy
• Lightweight purlins are
suitable for both insulated
and uninsulated ceilings
and walls
• The customer can choose
an alternative that best
suits his needs, the
required span length and
the loads the structure will
be subjected to

Light weight purlin LP-Z
Light weight purlin LP-Z
• LP-Z100 ÷ LP-Z350
• The Z section is excellently
suited as a roof purlin
• The major principal inertia axis
is in pitched roofs with normal
inclination in an approximately
vertical position and thereby
provides optimum load bearing
capacity against the weight of
structures and snow
Light weight purlin LP-Z
• The second moment of area
about the minor axis, on the
other hand, is so low that it is
usually advisable to tie the
sheet section on the slope of
the roof to the opposite slope
by a ridge moulding
• The Z section is installed on
the roof with the upper flange
pointing toward the ridge
• Z sections are applicable also
as wall purlins, installed with
the outer flange facing down
Light weight purlin LP-C
Light weight purlin LP-C
• LP-C100 ÷ LP-C350
• C sections can be used as wall
purlins or wall posts
• The C section differs from the
Z section by its centre of
torsion, which in the C section
is on the back side
• Due to torsion, a vertical load
acting on the section causes a
transverse force component
on the flange of the section,
acting from the web up toward
the upper flange
Light weight purlin LP-C
• If C sections are used as roof
purlins, they need to be
installed with the upper flange
pointing toward the ridge
• As wall purlins, on the other
hand, they are installed with
the flange facing up, whereby
wind pressure loads partly
counteract the self-weight of
the wall structure
• With wind suction loads, the
transverse force components
strengthen one another, and
tie rods may be required to
counteract their influence
Light weight purlin – LP-S
Light weight purlin LP-S
• LP-S150 ÷ LP-S400
• A sigma section exhibits
several plane areas separated
by folds
• This makes the manufacture of
sigma sections more complex
than the manufacture of Z and
C sections, but this is
compensated by the higher
durability values owing to the
better efficiency of the
dimensionally smaller plane
areas
Light weight purlin LP-S
• Thanks to this improved
efficiency, the height of sigma
profiles can be increased more
than the height of Z and C
sections
• Sigma sections can be used
on longer spans, or e.g. in
sigma frameworks which are
used in large span buildings to
achieve moderate spans
• A sigma framework is built
joining two sigma sections
back-to-back with 8-12mm
distance pieces, with similar
gauge sheet used as gusset
pieces
Light weight purlins – LP-H
Light weight purlin LP-H
• LP-H100 ÷ LP-H250
• The top hat section is wider
than the sections referred to
above
• This gives it considerably
higher lateral stiffness, which
makes it suited to applications
where the purlin is subjected
to transverse loads, as well
• Top hat purlins are attached
directly from the flanges
• They are used as roof purlins,
wall purlins or, for example, as
truss chords

Application in buildings
• Ruukki lightweight purlins can be used as a insulated
and uninsulated roofs in following buildings:
– production halls,
– warehouses,
– shopping centers,
– offices buildings,

• Ruukki’s PurCalc software is used to dimension the
purlins
Structural systems
• Structural systems types:

• Single - span system
• Two - span system
(multi - span system)
L
• Sleeve - extension system
L
L
L
• Overlap - extension system
L
L
L
Structural systems
• Single-span system
• Used in walls and roofs,
in moderate spans
– A simple system and the same support
reactions of primary rafters in centre
bays, small number of joint components
– Whole roof consists of similar purlins
L
– Higher consumption of steel
– Higher deflections
– Can be implemented with Z, C, top hat
and sigma profiles

Structural systems
• Two-span system
(multi-span system)
• Used in walls in 4-6m spans, and
in roofs in moderate spans
– Small deflections and small number of
parts requiring installation
– Amount of installation work limited
and different support reactions of
principal rafters
L
L
– Long sections, more difficult to handle
and can be implemented with Z, C,
top hat and sigma sections
L
L
L
Structural systems
• Sleeve-extension system
• Used in roof and wall structures
– System contains a special sleeve section,
normally either similar gauge to basic purlin
or max. 0.5 mm thicker. Optimal weight, small
deflections, sections easy to handle
L
L
– A larger number of component, more
installation work, for Z sections the sleeve
section is identical to the basic purlin section
and for sigma section, a C section is used as
sleeve section

Structural systems
• Overlap-extension system
• Used in roof and wall purlins, in
spans of 6-10m
– The purlins are overlapped inside one
another, a double purlin or a thicker
section in end bay
– Optimal weight and small deflections
