STEEL FASCIA DETAIL
To fix a pergola to steel fascia, the steel fascia must first be reinforced by installing 150 x 50mm noggings between
rafters. A timber trimmer can then be fixed to steel fascia by coach screwing to noggings.
A Joist Hanger to suit pergola beam thickness and distance between gutter and bottom of trimmer can then be fixed
at pergola beam spacing.
NOTE: Rafter overhang should be checked by an engineer to carry additional weight from pergola beam.
COMMON INSTALLATION
1. Locate the Joist Hanger accurately, then drive five MiTek 30 x 2.8mm galvanized reinforced head nails through all holes in each wing.
2. Place beam into position and drive three 30 x 2.8mm galvanized reinforced head nails through holes in each side of boot.

STANDARD GUTTER DETAIL
CONCEALED GUTTER DETAIL
1.Select a Joist Hanger size to suit timber pergola beam
thickness which will fit between bottom of timber fascia
and underside of gutter.
1. Fasten Joist Hangers to fascia using a string line to achieve a
straight line, placing the bottom of Joist Hanger approximately
25mm above the level of the bottom of pergola beam.
This will allow the bottom of the pergola beam to be trimmed
to sit neatly in the shoe of the Joist Hanger.
2. Fix Joist Hangers so that shoe is level with bottom of fascia.
