BACK CHANNEL INSTALLATION
The short edge of the back channel is the underside. The back
channel should extend 50mm past the end of the beam to allow
for overflow into the gutter. If multiple lengths are required, butt
the channels together and waterproof with silicone.
Determine what type of fascia you are attaching your unit to
and what type of fixings and brackets you require (refer to
“Attaching to a Structure” section). Pre-drill the back channel
on the ground. Locate the first hole 100mm from the edge of
the back face of each length of channel. Drill the other holes
at 500mm centres for timber and brickwork or 250mm
centres for steel fascia. Run two beads of silicone along the
back of the back channel, with one near the top edge to
ensure a water tight seal.
FASCIA ATTACHMENT
When fixing the back channel to fascia the roofing above
each rafter must be removed to give adequate space
to install the fascia strengthening brackets. M10 Bolts
connect the fascia strengthening brackets to the rafter and
fascia (the number of brackets required is determined by
the builder, but the spacing should not exceed 1200mm).
Silicone as shown in the diagrams. When fixing to timber
fascia (Figure 1.0) attach the back channel using 12x25mm
hex head timber fixing screws through the pre-drilled
holes. When fixing to steel fascia (Figure 1.1) attach the
back channel using 10x16mm hex head self drilling screws
through the pre-drilled holes. The back channel is bolted
through the fascia to the fascia brackets with one M10 bolt
per bracket. Insert BIP foam into the back channel to act as a
weather seal when the roof sheets are pressed into it.
ATTACHING TO A BRICK WALL
When fixing the back channel to a brick wall, pre-drill the
anchor holes using a masonry drill bit. Attach the back
channel using M6x65mm masonry anchors through the
pre-drilled holes (Figure 1.2). Insert the BIP foam into the
back channel to act as a weather seal when the roof sheets
are pressed into it.
STEEL HOUSE FRAME ATTACHMENT
When fixing the back channel to the steel fascia on a
steel framed house, the roofing above each rafter must
be removed to allow enough room to install the rafter
strengthening brackets.
Attach angle brackets to 75x25x1.6mm RHS reinforcement
using 12x20 self drilling screws. Place the brackets above
the first web or truss connection at least 900mm from the
wall, and directly over the wall. Fasten with four 12x20 self
drilling screws to the chord or rafter (Figure 1.3).
Attach the extended fascia strengthening bracket to the
reinforcing RHS using 12x20 self drilling screws at 200mm
centres. It is the builder’s responsibility to determine the
adequacy of the fascia and rafters and the frequency of the
brackets for each individual situation (Figure 1.3).
For additional bracing, fix a tie down brace to the adjacent
studs. Use two 12x20 self drilling screws to fix the tie down
to the to chord, and on each stud use two 12x20 self drilling
screws on either side of the truss or rafter. Fix the back
channel to the fascia as previously mentioned.

ATTACHING TO A STRUCTURE
WALL ATTACHMENT
For units attached to a wall, position the 5° Rafter Suspension
Brackets where the beams meet the wall. The top tab of the
bracket must be located under and over the back channel.
Use silicone to seal behind the suspension bracket and
fascia. Mark the holes and drill using an 8mm masonry bit.
Fasten the bracket to the wall with two M8 masonry anchors
to a minimum 65mm embedment, with one anchor either
side of the bracket back face (Figure 2.0).
SUSPENSION BRACKET ATTACHMENT
A suspension bracket is also used when a beam is suspended
from the fascia. The top tab of the bracket must be located
under and over the back channel. Use silicone to seal
behind the suspension bracket and fascia. For steel fascia a
minimum of three 12x20 hex head screws are fixed through
the back channel, suspension bracket and fascia (Figure
2.1). For timber, three 12x25 type 17 screws are used to fix
through the back channel, suspension bracket and timber.
FRAMEWORK ERECTION
END RAFTER BEAM (120 OUTBACK RAFTER)
When installing all beams, ensure the double thickness of
the beam is on top. Install the side rafter beam furthest from
the downpipe first. Lift the back channel end of the beam up
into the suspension bracket while supporting the other end
on an adjustable construction prop. Adjust the construction
prop to ensure the end of the rafter sits flush against the
back edge of the bracket. Fasten the side rafter beam to
the 5° Rafter Suspension Bracket using two 10x16 hex head
screws either side in the holes provided (Figure 3.0).
IN-LINE BEAM CONNECTION
To butt join beams together an in-line beam connector is used.
The connector is placed so the join is in-line with the centre
of a column. On the ground, slide the connector into the end
of the beam. Fix using four 10x16 hex head screws either side.
Push the exposed half of the in-line connector into the other
beam until both beams meet flush and fasten as previously
described (Figure 3.1).
RAFTER CONNECTIONS
Measure the front fascia beam. Mark where the end rafter
beams, intermediate rafters (if required) and columns meet.
Clip the post brackets onto the bottom of the front fascia
beam where the columns will sit. Fasten through the holes
in the post bracket with two 10x25 countersunk screws each
side into the flute of the beam (Figure 4.0). Place the Skillion
Rafter Brackets (5° Low) on the inside face of the front fascia
beam, aligning the top edge of the bracket with the top flute
of the beam (14mm from the top of the beam). Fasten the
bracket using six 10x16 self drilling screws (Figure 3.2).

FASCIA BEAM TO RAFTER CONNECTION
Lift the front fascia beam and slide the rafter bracket onto
the end of the rafter beam so that the end of the rafter
is butted up against the back of the bracket. Support the
front fascia beam on construction props allowing for a 5°
fall. Fasten the rafter beams either side with two 12x20 self
drilling screws (Figure 3.3).
INTERMEDIATE RAFTERS
I ntermediate rafters and purlins may be fitted at this stage
or following installation of the columns. Work progressively
from the first end of the unit. Locate the rafter brackets and
suspension brackets in the correct positions and fasten as
previously described. Lift the first intermediate rafter into
place and support on adjustable construction props (Figure
3.4). Secure all connections using two 12x20 hex head screws
either side of each bracket. Continue this process along the
Outback unit until the final end rafter beam is fixed in place.
PURLINS
Purlins can be installed in between, or over the rafters. Purlins
installed between rafters (checked-in purlins), are secured
with 68mm Purlin Brackets and Checked-In Purlin Brackets
over the intermediate rafters. Measure and mark the locations
for the brackets using a string line. Locate the purlin brackets
in the correct positions and fasten with four 12x20 hex head
screws through the back of each bracket in the holes provided.
Lift the purlins into place and secure all connections using
one 12x20 hex head screw either side of each bracket (Figure
3.5). Continue this process along the Outback unit until the
final end rafter beam is fixed in place.
Purlins installed on top of the rafters are to be positioned
correctly and fixed using two 14x95 hex head self drilling
screws through to the rafter (Figure 3.6).
FRAMEWORK CHECK
Check that the basic framework is square by ensuring
diagonal measurements from A to A and B to B are the same
(Figure 3.7). Recheck the falls are correct for the roof and
gutter (Figure 3.7).

REINFORCING THE 68 COLUMN
If 50x50mm square hollow sections (SHS) have been supplied
the fluted 68 Outback columns will need to be reinforced.
Cut the 50x50mm SHS 75mm shorter than the fluted post
and slide into the column. Ensure the square section is
positioned inside the column and fix using two 12 x 20 hex
head screws per side at both ends (Figure 4.0 and 4.1).
Regardless of whether the column is reinforced, slide the
top of the 68 Outback column over the post bracket until it
is flush with the underside of the fascia beam.
The unfluted faces of the column should be aligned with
each face of the post to beam bracket. Fasten the 68
Outback column to the post bracket using two 12x20 hex
head screws either side (Figure 4.1).
Use construction props or bracing to hold columns in
position, but do not concrete in place at this stage.
SQUARE HOLLOW SECTION (SHS) COLUMNS
If 65x65mm or 75x75mm square hollow sections (SHS) have
been supplied, an alternative post to beam connection
method is used.
Measure from the underside of the beam to the top of the
half brick and cut posts to this length. Screw the corner
connector or inline connector to the top of the SHS post
with two 12x20 hex head self drilling screws on either side
of the column (Figure 4.2).
Stand the post in position. Screw the connector to the
outside face of the Outback beam with 12x20 self drilling
hex head screws (Figure 4.2).
Use construction props or bracing to hold columns in
position but do not concrete in place at this stage.

FOOTING PLATES
Footing brackets are available if the posts are to be fixed
to an existing concrete slab. Establish the column lengths
by measuring the distance from the underside of the fascia
beam to the concrete slab, less the thickness of the footing
plate (or 20mm for Outback footing plate).
68 OUTBACK FOOTING PLATE
For non-reinforced 68 Outback posts, cut the columns to
length, and assemble the footing bracket by sliding the legs
of the footing upstand through the slots in the footing plate
(Figure 5.0). The upstand bracing must be located between
the legs of the upstand.
Slide the assembled footing bracket and bracing into the
bottom of the column, and fasten with two 12x20 hex head
screws either side ensuring the top screws are located at
least 15mm from the top of the upstand with screws being a
minimum 30mm apart (Figure 5.0).
Slide the top of the column over the post bracket and align
the column and footing bracket. (Note: It may be necessary
to lift the fascia beam slightly to slide the column over the
post bracket). The unfluted faces of the column should be
aligned with each face of the post to beam bracket. Fasten
using two 12x20 hex head screws either side (Figure 4.0).
Use construction props or bracing to hold columns in
position but do not bolt to the concrete slab at this stage.
SHS REINFORCED COLUMN FOOTING PLATE
Slide the SHS reinforced footing bracket into the bottom of
the column, and fasten with two 12x20 hex head screws on
either side of the post (Figure 4.0). Locate the top screws
approximately 100mm from the base of the footing plate,
and the bottom screws 50mm from the base (Figure 5.1).
Slide the top of the column over the post bracket and align
the column and footing bracket. (Note: It may be necessary
to lift the fascia beam slightly to slide the column over the
post bracket). The unfluted faces of the column should be
aligned with each face of the post to beam bracket. Fasten
using two 12x20 hex head screws either side (Figure 4.1).
Use construction props or bracing to hold columns in
position but do not bolt to the concrete slab at this stage.
SHS COLUMN FOOTING PLATE
Slide the SHS column footing bracket into the bottom of the
column, and fasten with two M10 bolts through the post
(Figure 5.2).
Screw the corner connector or inline connector to the top
of the SHS post with two 12x20 hex head self drilling screws
on either side of the column (Figure 4.2). Stand the post in
position and screw the connector to the outside face of the
beam with 12x20 self drilling hex head screws (Figure 5.2).
Use construction props or bracing to hold columns in
position, but do not bolt to the concrete slab at this stage.

ROOFING
TURNING UP THE ROOFING ENDS
While still at ground level the valleys on the high end of the
roof decking need to be turned up using a turn-up tool or
adjustable spanner to aid in weather proofing (Figure 6.0).
At the low end of the sheets the valleys of each corrugation
should be turned down into the gutter using a turn up/down
tool or adjustable spanner.
LAYING AND INSTALLING THE ROOFING
Roof sheets should be laid into the prevailing wind and sit
neatly on the preceding roof sheet, with a side lap of 1.5
corrugations (Figures 6.1 and 6.2). Avoid ‘stretching’ the
width of the sheet when installing as this could allow wind
and rain to enter.
Lift the first sheet into place and push it firmly into the BIP
foam in the back channel to weather proof it. Roofing should
have a 50mm overhang into the gutter. Check the sheet is
square against the back channel and side rafter. At the back
channel end, rivet the sheet from underneath through the
bottom of the back channel with 3.2mm rivets (Figure 6.2).
Seal the rivets with silicone inside the back channel.
At each supporting purlin, fix the sheet with 12g x 35mm (for
CGI) or M6x50mm (for Maximus 22) hex head self-drilling
screws with neoprene washers (Figure 6.3).
Side lap fixing is recommended to maintain a weather proof
seal and to secure the overlap (Figure 6.4). This is best
done with either 8 x 12mm self drilling stitching screws or a
3.2mm blind rivet (rivets should be silicone sealed to prevent
water penetration). It is recommended side lap fasteners are
secured mid-span, when spans exceed 900mm.

GUTTER OUTLET ASSEMBLY
Before attaching the gutter mark the position of the
outlet. Place the downpipe in line with the column and
mark and cut a hole in the base of the gutter near the back
edge. Insert the downpipe outlet from the inside of the
gutter and rivet in place using four 3.2mm rivets (Figure
7.1). Remove any swarf and waterproof with silicone.
GUTTER ATTACHMENT
Check the roof sheets overhang into the gutter by 50mm and
the gutters are square in relation to the framework. Lift the
gutter into position and fix with rivets at one metre spacings
through the valley of the roof sheets into the gutter’s back
lip (Figure 7.2). Install gutter straps at a maximum spacing of
one metre apart. The downpipe is not attached at this stage
as the columns are not yet fixed in their vertical position.
DOWNPIPES
Before attaching the downpipes, rivet the downpipe brackets
to the column. Slide the downpipe over the downpipe outlet
and rivet into position. Rivet the downpipe to the brackets.
Weatherproof all the fasteners with silicone.
CAPPING & FLASHING
To prevent moisture from entering the beams and for
aesthetics, any beams with exposed ends require end caps
to be fitted. Align the end cap and push into the exposed
beam end (Figure 8.0).
If Outback columns are used, the post caps can be fitted
over the post-beam connection. Apply a small amount of
silicone to back of post cap, align the two lugs with the two
exposed holes of the post bracket and push firmly (Figure 8.1)
Attach the barge flashing by screwing the lower lip to
the rafter using 12x20 hex head self drilling screws, and
rivet the top section to the crest of the roof sheet at
500mm centres (Figure 8.2).
GUTTER ASSEMBLY
GUTTER PREPARATION
To establish the gutter length, measure the length of the
front fascia beam. Cut the gutter to length and attach the
stop ends with four rivets per stop end. Remove any swarf
and waterproof with silicone (Figure 7.0).

FINAL FIXING
FIXING INTO THE CONCRETE FOOTING
Thoroughly check the posts with a spirit level. When plumb,
fill the post hole with approximately 150mm of concrete and
use a shovel or pole to agitate the concrete to remove any air
pockets. Repeat this process until the hole is full, continually
checking the posts as you go. The concrete must have a
slight slope that runs away from the column to ensure any
water does not pool around the base (Figure 9.0). Once the
concrete is set remove any temporary bracing or props.
FIXING ONTO EXISTING CONCRETE
68 OUTBACK COLUMN
If the 68 Outback Columns are to be fixed to an existing
concrete slab with a footing plate, each plate must be fixed
to the concrete with two M12x75 masonry anchors or two
M12x75 screwbolts (Figure 9.1).
SHS COLUMN
If using SHS columns, the footing plate is to be fixed to
the concrete slab with four M12x75 masonry anchors or
screw bolts (Figure 9.2).
SHS REINFORCED OUTBACK COLUMN
Reinforced Outback Columns are to be fixed to the
concrete slab with four M12x75mm masonry anchors or
screw bolts (Figure 9.3).
Note: Anchors to be installed in accordance with
manufacturer’s specifications with appropriate concrete
edge distance as per manufacturer’s requirements.
IMPORTANT NOTE
Do not allow soil to remain in permanent contact with the
columns as corrosion will result in the base of the column. Refer
to the ‘Selection, Use and Maintenance of Stratco Steel Products’
brochure for complete details of the maintenance requirements.

MAINTENANCE
Regular maintenance is essential to maintain the good looks of all Stratco steel products and to ensure
you receive the maximum lifespan possible. Washing with clean water must be frequent enough to
prevent the accumulation of dust, salts, and pollutants that may reduce the life of the product. Stratco
steel products that are regularly washed by rain require no additional maintenance. No Stratco steel
structure or materials are recommended for use over, or in close proximity, to swimming pools or spas.
No material that retains water (such as dirt or paving sand) should be placed against the columns. Care
must be taken when determining the location of Stratco steel products so that they are not placed in
close contact with sources of pollution or environmental factors that could aect the life of the steel.
Refer to the ‘Selection, Use and Maintenance’ brochure for more information.
