|LYSAGHT KLIP-LOKTM 700 is the new generation of wide-cover concealed-fixed cladding. Made of high tensile steel of 550 MPa yield strength, it spans wider, with better uplift performance than all available comparable profiles.
Visually, you get a bold rib that makes a strong statement rising from the flat pans that are cross micro fluted.Our extensive research shows that thermal expansion and contraction can be controlled much better using a concealed fixed system. Since the effect is on the longitudinal direction, wider coverage of LYSAGHT KLIP-LOK™ 700 provides the best alternative. It is not only suitable for general environment, but works well in both coastal and snow environments.
LYSAGHT KLIP-LOKTM 700 is truly a superior product developed by BlueScope Steel’s Research and Development centre at Sydney, Australia after extensive research for a number of years.The profile is fixed on a specially designed clip known as KL-70,manufactured from high tensile steel base and designed tower to withhold high wind pressure. This provides accuracy, economy and ease during the installation and makes it a superior product designed to last.
The fixing clips are first secured to steel or timber supports, then LYSAGHT KLIP-LOKTM 700 is laid directly onto the clips. With no exposed fasteners, the straight lines of your roof remain clean and smooth.
LYSAGHT KLIP-LOKTM 700 can be manufactured on site using world-class mobile roll-forming technology, which not only gives single length from the ridge of the roof to the eave, but also helps to make it a leak-proof structure with better control over quality installation.
|Simple, Low Cost Fixing
Long, straight lengths of LYSAGHT KLIP-LOKTM 700 can be laid
in place and easily aligned. Fixing with our new clips is simpler
and faster than ever before. The smaller number of clips for a
given area provides extra economy.
Our patented transverse fluting significantly adds to the
performance of this revolutionary product making it superior to
any other concealed-fixed cladding.
LYSAGHT KLIP-LOKTM 700 is 700 mm wide covering profile with nominal 43 mm deep ribs. The specially designed shape of the profile combined with the high tensile property of base steel help in better interlocking of the panels on lateral ends. The profile is fixed on a specially designed clip (KL-70) to the base purlin,avoiding any external screw on the roof and making it watertight and leak proof in comparison to any
conventional screw down profile (Refer figure 1).
LYSAGHT KLIP-LOK™ 700 profile is manufactured from high
strength steel grade with minimum yield strength of 550 MPa.
The coated steel is available as ZINCALUME® steel (150 g/m2
min. zinc-aluminium alloy coated steel) as per AS1397 or
COLORBOND® steel (pre-painted steel) conforming to AS2728

Masses Maximum Support Spacing (in Millimetres)
The maximum recommended support spacings are based on
tests conducted in accordance with AS1562.1-1992, AS4040.1-
1992 and AS4040.2-1992.
Roof spans consider both resistance to wind pressure and light
roof traffic (traffic arising from incidental maintenance). Wall
spans consider resistance to wind pressure only.
The pressure considered (in accordance with IS 875.3) is based
|on buildings up to 10m high, Zone 3 (Basic wind speed
Vb=47m/s), Class A, Terrain category 3, K1 = 1.0, K2 = 0.91, K3 =
1.0, with the following assumptions made;
Roofs:Cpe = – 1.20 (internal cladding spans)
Cpe = – 2.0 (single and end cladding spans)
Cpi = + 0.2
Cpe = – 0.80 (internal cladding spans)
Cpe = – 1.20 (single and end cladding pans)
Cpi = + 0.2
These spacings may vary for particular projects, depending on
specific structure characteristics.

Limit States Wind Pressures
LYSAGHT KLIP-LOK™ 700 offers the full benefits of the
latest methods for modelling wind pressures.
The wind pressure capacity table is determined by full scale
tests conducted at BlueScope Steel’s NATA- registered testing
laboratory, using the direct pressure-testing rig. Testing was
conducted in accordance with AS 1562.1-1992 Design and
Installation of Sheet Roof and Wall Cladding-Metal and AS
4040.2-1992 Resistance to Wind Pressure for Non-cyclonic
The pressure capacities for serviceability are based on a deflection
limit of (span/120) + (maximum fastener pitch/30).
The pressure capacities for strength have been
determined by testing the cladding to failure (ultimate capacity).
These pressures are applicable when the cladding is fixed to a
minimum of 1.0 mm, G550 steel purlin. For material less than 1.0
mm thickness, seek advice from your nearest Tata BlueScope
Building Products office.
If this product is to be used in marine, severe industrial, or
unusually corrosive environments, ask for advice from your
nearest Tata BlueScope Building Products Office.
|Metal and Timber Compatibility
Lead, copper, free carbon, bare steel and green or some chemically-treated timber are not compatible with this product.Don’t allow any contact of the product with these materials, nor discharge of rainwater from them onto the product.
Supporting members should be coated to avoid problems with underside condensation. If there are doubts about the compatibility of other products being used, ask for advice from your nearest office.
Optimum product life will be achieved, if all external walls are washed regularly. Areas not cleaned by natural rainfall (such as top portion of walls sheltered by eaves) should be washed down every six months.
Walking on Roofs
Generally, keep your weight evenly distributed over the soles of both feet to avoid concentrating your weight on either heels or toes. Always wear smooth soft-soled shoes; avoid ribbed soles that pick up and hold small stones, swarf and other objects.
Storage and Handling
Keep the product dry and clear of the ground. If stacked or bundled product becomes wet, separate it and wipe it with a clean cloth to dry thoroughly. Handle materials carefully to avoid damage: don’t drag materials over rough surfaces or each other,
don’t drag tools over material and protect it from swarf.Turn up/down Tools
On all roofs of pitches less than 150, the high end of all sheets must be turned up to stop water from being driven under the flashing and into the building.Similarly, the pans at the gutter end must be turned down to stop water running back along the underside of the sheets.Cutting
For cutting thin metal on site, we recommend a circular saw with a metal-cutting blade because it produces fewer damaging hot metal particles and leaves less resultant burr than does a carborundum
disc.Cut materials over the ground and not over other materials.Sweep all metallic swarf and other debris from roof areas and gutters at the end of each day and at the completion of the installation. Failure to do so can lead to surface staining when
the metal particles rust.
All fasteners shall conform to Australian standard AS3566 – 2002
Class 3 (minimum) for external application.
Where insulation is to be installed, you may need to increase the
length of the screws given below, depending on the density and
thickness of the insulation. When the screw is properly tightened:
• into metal: there should be at least three threads
protruding past the support you are fixing to, but the
Shankguard must not reach that support
• into timber: the screw must penetrate the timber upto
the same amount that the recommended screw
would do if there were no insulationSealed Joints

Before starting work ensure that:
• The support for your cladding is truly in the same plane
• The minimum roof slope conforms to our recommendation
• The overhang of sheets from the top and bottom supports
don’t exceed our recommendation
Make necessary adjustments before you start laying sheets
as per our recommendations.
Orientation Sheet before Lifting
Consider which end of the building is best to start from. For
maximum weather – tightness, start laying sheets from the end
of the building that will be downwind of the worst – anticipated or prevailing weather (Refer figure 2). It is much easier and safer to turn sheets on the ground than up on the roof. Before lifting sheets on to the roof, check that they are the correct way up and the overlapping side is towards the edge of the roof from which installation will start.
Place bundles of sheet over or near firm support, not at mid span of the roof members.Steps for Installation
1. Lay wire mesh or chicken wire mesh on the purlins and
weld or screw the wire mesh to each purlin (Refer figure 3).
|2. Position the first clips on each purlin by placing onto the
purlin nearest to the gutter (Refer figure 4).3. Fix the first clip on the purlin so that they point in the direction of laying. Ensure the clip is 90 degree to the edge of the sheet.4. Align the clips with the spacer using a string line (or the first sheet as a straight edge) to align the clips as you fix a clip to each purlin working towards the high end of the roof.5. Drive hex head screw through the top of the clip, into the purlin.
6.Work along the edge of the gutter, ensuring it aligns correctly at its end in relation to the gutter and ridge (or parapet or transverse wall).7. Place the glass wool insulation between the purlin (Refer figure 5).8. Measure the distance from the gutter end of the sheet to the fascia or purlin.9. Position the first sheet so that the overhangs are of the desired amount (usually 50 mm) to the gutter. It is important to ensure this first sheet is placed squarely to adjacent edges (Refer figure 5).10. Engage the sheet with clips using vertical foot pressure on all the ribs over each clip (Refer figure 6).11. Fix the next row of clip, one to each support with the slots and tabs engaged. Be sure the clip is 90 degree to the edge of the sheet.
|12. As before, place the next sheet over its clips also engaging the edge of the preceding sheet.13. Accurately position the sheet so that it overhangs the desired amount into the gutter. It is important that you keep the gutterend of all sheets in a straight line.14. Fully engage the two sheets along the overlapping rib. You can do this by walking along the full length of the sheet with one foot in the centre pan of the previous sheet and the other foot applying vertical pressure to the top of the interlocking ribs at regular intervals. It is important that you don’t walk in the unsupported pan besides the overlap. A rubber mallet may help engagement of laps on long spans (Refer figure 6).
15. Similarly, engage all the clips by applying vertical foot pressure to the top of the other ribs over each clip. It is essential that the sheets interlock completely. It is important that your weight is fully on the sheet you are installing.Check alignment occasionally Occasionally check that the sheets are still parallel with the first sheet, by taking two measurements across the width of the fixed cladding.At about half way through the job, perform a similar check but take the measurements from the finishing line to aim for the final sheet to be parallel with the end of the roof. If the measurements are not close enough, lay subsequent sheets slightly out of parallel to gradually correct the error(Refer figure 7). To allow
|this to happen, flatten the tabs on the base of subsequent clips
– the slot in the clip will allow the clips to be fixed out of standard pitch.
Fix the last sheet
If the final space is less than the full width
of a sheet, you can cut a sheet along its length and shorten
the clips as appropriate.
Installing KLIP-LOK™ 700 wall
The installation procedure for walls is similar to that described
for roofs. To engage clips, use a rubber mallet (instead of foot
pressure). To prevent KLIP-LOK™ 700 from sliding downward in
the fixing clips, you should pierce-fix through each sheet under
the flashing or capping, along the top of the sheets.
LYSAGHT KLIP-LOK™ profile has been tested with the latest
pressurised air chamber for modelling wind pressures (Refer
photograph). The wind pressure capacity table are obtained from
our direct – pressure test rig which accurately reproduces the
wind conditions experienced in the field. It does not uses air
bags and applies pressure uniformly over the entire profile
including ribs. (Refer figure 8).Older air bag method used by others distribute pressure unevenly, so that air bags can produce misleading results and inflated strengths as it does not allow pressure to be applied to ribs (Refer figure 9).
