DECKING
TURNING THE DECKING ENDS
While still at ground level the ends of the decking need to be
turned up or down approximately 30 degrees using a turn
up/down tool to aid in weather proofing. Turn the ends of
the decking up at the back channel end and down at the
gutter end (Figure 6.0).
LAYING AND INSTALLING THE DECKING
Decking should have a 50mm overhang into the gutter and is
laid with the overlapping rib facing away from the prevailing
wind (Figure 6.1). Ensure all of the sheets have locking ribs
on the same side. Mark the back channel and front fascia
beam every 1000mm to check the decking is laid square.
Lift the first sheet into place and push it firmly into the BIP
foam in the back channel to weather proof it. Check the
sheet is square against the back channel and side fascia
beam. At the back channel end, rivet the decking from
underneath through the raised edge on the bottom of the
back channel with two 3.2mm rivets per pan (Figure 6.2).
Seal the rivets with silicone. At each supporting beam, fix
the sheet with two 12x20 hex head self-drilling screws per
pan (Figure 6.2) (In cyclonic conditions use three 12x20 hex
head self drilling screws per pan on supporting beams and
three rivets per pan at the back channel). Remove any swarf.
ATTACH COLUMN TO POST BRACKET
Slide the top of the column over the post bracket and align
the column and footing bracket if applicable. It may be
necessary to lift the fascia beam to slide the column over the
post bracket. The un-fluted faces of the column should be
aligned with each face of the post to beam bracket. Fasten
with two 12x20 hex head screws either side (Figure 5.2). Post
caps are used to cover the screw heads, press firmly into
position, silicone can be used to provide a better fixing.
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 5.3).
Stand the post in position. Screw the connector to the
outside face of the Outback beam with 12x20 self drilling
hex head screws (Figure 5.3).
Use construction props or bracing to hold columns in
position but do not fix in place at this stage.
