Standard
Unit
Pricing is according to our most basic of the range.
It includes:
- the
polycarbonate roofing material
- the
curved roofing frame
- straight
posts up to 2.66m
- fixing
system to bolt down to a concrete slab
This
is called a free standing attached model. It is fixed
down to concrete by its posts and feeds into the guttering
of a house or structure on one or more sides. A simple
bracket is secured to the structure to give lateral
stability.

Bar
& Bracket
Where eaves /overhang of the roof are involved, a couple
of options are available. The first is a bar & bracket
system, attaching through the fascia into the rafters.
This system is available up to 3.9m wide.
Knee
Braces
Knee braces are used to increase the strength rating
of a pergola. They are used when a unit is not attached
or semi-attached to an existing structure. They are
also used in higher wind category areas such as
exposed rural or cyclonic zones.

Dog
Leg Posts
Units above 3.9m are too large for the eaves to support
- it must be supported down to the slab or footings.
In these cases a 'dog leg' post can be used to offset
the post against the wall of the house and not encroach
on the entertainment area.
Oversize
Posts
As the units increase in size so do frame members. A
3.9m wide canopy may have 50 x 50mm posts, while a 6.2m
canopy will have 100 x 50mm posts. As a 2.66m post height
is standard all units above this height may need to
increase the dimensions or wall thickness of the post
to compensate.

Horse
Shoe Brackets
Horseshoe brackets are used when there is not a position
available to bring down a post because of windows or doors.
These attach to the side of and strengthen the rafters.
This is called an attached pergola.
Overhang
It is possible to overhang the roofing at each end by
up to 1m. This has some great advantages. Firstly it
allows posts to be positioned wherever and still make
the most of standard roofing sizes. Secondly it can
provide weather proofing overlapping an adjacent roof
line. Thirdly it can reduce the number of posts used
especially if a bay is over span.

Guttering
In these days of water saving you may want the flow of
water onto your garden. If the pergola is attached or
free standing attached it can feed back into the guttering
of your house. If you are applying for permit you will
require a gutter on the outside of your pergola, feeding
off into a water tank or stormwater drain.
Powder Coating / Painted
The standard price is for galvanised steel finish and
can be painted by the owner. The frame is divided into
two parts, the roof members and the posts. If the client
wants colour the most important place is the posts,
as visually they are the most noticed. The posts are
also the area most knocked and handled in day to day
use. Powder coating is very strong and does not add
a lot of cost. Coating the roof members is not as important,
as the gal colour blends in with the roofing. However
if a client would like colour, two options are available.
In the smaller units powder coating is available at
three times the cost of the posts or painted at about
two times the cost of the posts.

Concrete
Slab or Pad Footings
Bolting down to a concrete slab is by far the most cost
efficient method. Oversizing the posts to go into the
ground, digging and pouring the concrete pads can cost
close to the price of pouring a slab. However before pouring
a slab it is worth checking with Modular Canopies as there
may be some special requirements of size or stiffening
thickness, especially with the larger units. If using
pavers or bitumen, concrete pads are required unless there
is a concrete slab beneath.
