SITE PREPARATION

Excavate a 300mm square hole
(approx) for each post to a depth
of at least 300mm. (see 

Fig.A

)

We would recommend that you
use 

MetCrete

, fast set post fixing

concrete to fix your posts. Easy
to use, it sets in just 10 minutes.

1. Begin with the roof assembly.

2. Mark off five points along the length of each 

of the curved beams where the rafters will be 
fitted (see 

Fig.1

). It is recommended that the 

centre is marked first (

1

) and the other points 

measured from it.

3. Fix the rafters to the curved 

beams using screws (

w

)

from the topside of the 
rafters into the curved 
beams.

4.  Use the Trellis Sections 

(

C

) to mark where the 

‘L’ Clips (

z

) need to be 

fitted to the posts. 
The ‘L’ Clips should be 
positioned so that they 
fit into the corners of 
the trellis. The top clips 
should be 100mm below 
the shoulder at the top 
of the post (see 

Fig.2

).

5.  Fit the trellis to the 

metal brackets using 
screws (

y

).

NB. Check the posts 
are the correct way 
around so that they fit 
inside the roof curved 
beams (see 

Fig.3

).

6. Fit the roof assembly 

onto the posts of the 
side assemblies and fix 
at the desired position 
with screws (

x

).

Make sure the overhang 
at each end is the same.
