PANELRIB® 1110 is an attractive, slightly fluted wall and ceiling cladding for exterior and interior use on straight or curved surfaces. Its elegant appearance makes it suitable for many applications where a flat sheet would not normally be considered. These include ceilings, partition facings, screens,garage doors, fascias and barge boards.
PANELRIB® 1110 is manufactured out of high strength steel and has longitudinal flutes that provide rigidity and strength along the ength of the sheet, while retaining full flexibility across the width.l
It can be used with the flutes vertically or horizontally. However,
PANELRIB® 1110 is not intended as a roofing material.Hence, we can say that for exterior and interior walls and on straight or curved surfaces with horizontal or vertical flutes,
PANELRIB® 1110 is easy to fix. Moreover,
• It provides easy solutions for false ceiling and wall partition
• Its long, straight lengths minimise fixing costs 



PANELRIB® 1110 is 1110 mm wide coverage profile with nominal 3.5 mm deep rib with pitch of nominal 50.5 mm centre to centre distance. (Please refer to fig. 1)panelrib_2

Material Specification
LYSAGHT PANRLRIB® 1110 is manufactured out of high
strength steel. The coated steel is ZINCALUME® steel, which is
a zinc-aluminium alloy coated steel complying with AS 1397,
G550, AZ150 (550 MPa minimum yield stress, 150 g/m2
minimum coating mass) or COLORBOND® steel, a pre-painted
steel conforming to AS/NZS 2728 Type 3-4.
(Please refer to ZINCALUME® steel & COLORBOND® steel brochure for details)flexiclad_3LengthsSheets are supplied custom cut.


Length: + 0 mm, – 15 mm
Width: + 0 mm, – 4 mm




Maximum Support Spacing (mm)
The maximum recommended support spacings are based on
tests conducted in accordance with AS1562.1-1992, AS4040.1-
1992 and AS4040.2-1992.
Wall Span considers resistance to wind pressure only.
The pressure considered (in accordance with IS 875.3) is based
on buildings up to 10m height, 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:flexiclad_6
Cpe = – 0.80 (internal cladding spans)
Cpe = – 1.20 (single and end cladding spans)
Cpi = + 0.2
These spacings may vary for particular projects, depending on
specific structural characteristics.
Limit State Load Tables
PANELRIB® 1110 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.
Tests were 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 Pressures for Noncyclonic
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.For material less than 1.0 mm
thick, seek advice from your nearest Tata BlueScope Building
Products office.
Adverse Conditions

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 & Timber Compatibility

Lead, copper, bare steel and green or some chemically treated timbers are not compatible with this product. Thus, don’t allow any contact of the product with those materials, nor discharge of rainwater from them onto the product.If there are doubts about the compatibility of products being used, ask for advice from nearest Tata BlueScope Building
Products office.


Optimum product life will be achieved if all external surfaces are washed regularly.Areas not cleaned by natural rainfall (such as the top
portion of walls sheltered by eaves) should be washed down every six months.

Storage and Handling
Keep the product dry and clear of the ground. If stacked or bundled product becomes wet, separate it, wipe it with a clean cloth and stack it to dry thoroughly.Handle materials carefully to avoid damage: don’t drag materials over rough surfaces or each other; carry tools,don’t drag them;and protect it from swarf.
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 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.
Sealed Joints
For sealed joints, use screws or rivets and neutral-cure silicone sealant branded as suitable for use with ZINCALUME® steel.
Areas The information in this brochure is suitable for use only in areas where a tropical cyclone is unlikely to occur.Ask for advice from your nearest Tata BlueScope Building Products office on designs to be used in cyclonic areas.


PANELRIB® 1110 steel cladding can be attached to the
frame with the flutes either vertically or horizontally. When
fixing with flutes horizontally, ensure that the top sheet
overlaps the sheet below.
If end laps are necessary because of very long runs, allow
at least 75 mm lap.
For sheets fixed on external applications where sealing is
required, seal end laps with a suitable sealant.
Location of Fasteners
A fastener should be located either at the side lap or
adjacent to it. For a quality finish, fasteners at the ends of
PANELRIB® 1110 sheets, including end laps, should be
located at every second valley. At intermediate supports,
four fasteners should be used. They should be equidistant
across the sheet.
For internal applications not subject to wind loads, the
number of fasteners may be reduced by 50%, except for
ceiling applications.
Side Lapping
Three types of side lapping methods are used: the
overlapping flute, the butt joint and the edge lap joint.
When using the overlapping or edge lap joint
methods, side lap fasteners are required at 200-300 mm

1. All screws are self drilling, self tapping with EPDM sealing washer unless otherwise noted
2. The number of screws per support are per Sq.m. and are only for guidance, based on support spaced at 1 m and wall spaced at 0.6m
3. HG refers to Hi-Grips
4. * – the screw quantity is based on an average number of screws
