2. » INTRODUCTION
» The origin of the word is the Late
Latin pergula, referring to a
projecting eave.
» A pergola is a garden feature
forming a shaded walkway,
passageway, or sitting area of
vertical posts or pillars that
usually support cross-beams and
a sturdy open lattice, often upon
which woody vines are trained.
» a structure usually consisting of
parallel colonnades supporting an
open roof of girders and cross
rafters

6. TYPES OF PERGOLAS
1. STEEL PERGOLAS
As with steel roofing materials, steel used in the
construction of the pergola frame itself needs to
be protected from rust and corrosion. This can be
done with a 100% zinc coating (known as
galvanised steel) or it can be coated in a zinc-
aluminium combination commercially known as
Zincalume or Galvalume. The steel can be powder
coated with a paint and then baked, both for
added visual appeal and to provide a much wider
range of colours to choose from.
Steel poles won’t deteriorate with time or water exposure like timber does, and it can
also provide a lot more strength
Using steel also greatly reduces the risk of your home catching alight should it be
exposed to a bushfire.
Steel is also more weather proof than wood,
7. PITCHED PERGOLAS
A pitched pergola’s roof is attached to the house, a
tall nearby wall or another standing structure and
slopes downward towards the other end of the
pergola creating a single slope. This can be a little
confusing - generally the term 'pitched', when it's
used to describe a roof, means that it's been built
so that it slopes.
OPEN TOP PERGOLAS
Open top pergolas help to define a space without completely enclosing it
An open top pergola is a pergola in the traditional
sense of the word; the dictionary defines a pergola
as an open-roof structure designed to support
vines and trellises. These types of pergolas lend a
distinct Mediterranean feel to a backyard, and
have been in use for centuries. The open roof
structure gives the space the frame of being an
indoor room, but one which is still completely
open to the elements.
8. GABLED PERGOLAS
A gable is the triangular space at the end of a roof
consisting of two sloping roof halves. On a house,
these are typically load bearing structures but as
pergolas are generally much lighter and don’t have
load bearing walls to support, the gable is largely
decorative. On more sizable pergolas gabled roofs
can be designed in such a way as to be structurally
useful, and then given a little extra garnish for
appearances
They offer a little additional protection from the
sun should it happen to shine down from an angle
not fully covered by the roof. A gable can also act
as a cross beam from which to suspend shade
cloth, or some other sort of screening material and
can even be trellised to train vines along. Closed
gables add to the feeling that a pergola is
'enclosed', and increase the sense that the pergola
is an indoor room outdoors.
9. Differents types of pergolas materials
Wood
Along with adding to your home’s overall property value, pergolas made from wooden
materials offer a natural yet elegant look for your backyard.. Many wooden pergolas
come in kits equipped with pre-cut or pre-drilled pieces that eliminate the common
hassles of installing other wooden structures; this means you can spend less effort on
labor and more time enjoying your backyard. From sheltering your garden to shading
your patio, a wooden pergola is a functional accent piece that’s as attractive as it is useful.
12. Steel
Steel pergolas are some of the sturdiest ones on the market. If you want to add more shade to
your backyard, you’re in luck. It’s incredibly easy to attach sheets and curtains to steel-framed
pergolas, and their resilient structure helps to ensure any linen materials you put up stay in place.
Steel pergolas are also a great option for sheltering gardens, and you can even use the beams to
have vines wrap around the structure, creating a more earthy, natural appeal. Hanging plants from
the rafters of a steel-framed pergola is also an easy and attractive way to create some shade on
your deck or patio.

14. Aluminum
If you’re concerned about cost-effectiveness, going with an aluminum-based pergola is a more
financially-friendly option. From a material standpoint, aluminum pergolas require very little
maintenance as they won’t rot and their nonporous surface is built to withstand weathering.
Aluminum pergolas are also designed for a pain-free installation process, which caters to first-
time pergola owners or those who tend to shy away from DIY projects. Even if you plan on
installing them on your own, aluminum beams and frames are extremely lightweight, compared
to other material options. Perfect for patios directly linked to your house, aluminum pergolas are
especially recommended for anyone looking for an attached pergola structure.
15. Installing the Posts
The posts are composed of pressure-treated 4 x 4
cores that are sheathed with 1 x cedar. We secured
the post cores to a concrete pad with steel post-
base anchors. If you're not building on a pad, use
longer posts and set them in the earth below the
frost line.
Lay out the post positions and mark the screw
locations.
We used 1/4-in. Tapcon screws that
thread into 3/16-in. holes bored with a
hammer drill
Hold each post
plumb and drive
nails through the
anchors into the
wood. If necessary,
brace the posts so
they stay plumb.

How to Build a Pergola
16. Attaching the Support Beams
Cut the four 2 x 6 cedar support beams to length,
use a template to mark the curved notches at the
ends and cut the notches with a jigsaw. Clamp the
beams in place, and check that they're level and
that the posts are plumb.
Then secure each end with four 3-in. No. 10
screws.
When adding the second of each pair
of beams, check that they're level
across the top edges
17. Adding the Crossbeams
The 2 x 6 crossbeams are notched to fit over the
support beams.
Cut the notches with a dado blade in the table saw,
or lay out each notch and use a jigsaw to remove
the waste.
Then, make the curved end cuts.
Install the crossbeam pairs at the posts first. When
they're in place, bore screwholes down through
their top edges and screw crossbeams to the
support beams. Then add the three remaining
pairs with similar spacing.
18. Post Trim and Braces
Cut the post trimpieces to length and width. Note
that you'll need to notch some of the pieces to fit
between the support beams, or you can make filler
blocks to cover the post cores at these areas.
Instead of trying for perfectly flush corners, we
dimensioned the trim to leave a 1/8-in. shadow
line, or reveal.
Secure the trimpieces to the posts with
construction adhesive and galvanized finishing
nails.
Use 2 x 6 stock for the diagonal braces. Cut the
ends to length at 45 degrees, and use a flexible
stick to lay out the shallow curve on the lower
edge of each brace. Fasten the braces to the posts
and beams with screws.

19. Fitting the Top Slats
Cut the five 2 x 4 slats to length and shape the
ends.
Clamp each slat in place and mark the
crossbeam notch positions.
If you use a table saw and dado blade to
make the cuts, be sure to support the long
stock at the opposite end.
Then, bore
pilot holes and
attach the slats
with 3-in. No.
10 screws.

20. Capping the Posts
To make the post caps, cut square blanks and then
set the table saw blade to 15 degrees for shaping
the bevels.
Use a longer board with a stop across the end as a
sled to guide each blank through the blade. Clamp
the blanks to the sled when making the cuts.
Secure the caps with 6d galvanized
finishing nails and construction
adhesive.
