Congratulations on your purchase of your DGI GLULAM beam/s.
You can be assured that your beams are of the highest quality
having been manufactured to the exacting standards of AS/NZS
1328 and AS/NZS 1491.
Being timber (a natural product) your beams are subject to
change in atmospheric conditions, and therefore requires some
care in handling and storage.
DGI GLULAM is warranted free from manufacturing defects and
the performance of the product is guaranteed providing the
conditions relating to handling and onsite storage are adhered
to. It is also assumed that your beams have been properly designed
for the loads they are to carry.
Because we have no control over installation of your DGI GLULAM
beams, this guarantee does not cover any part of the installation
/ erection process.
On receipt of your DGI GLULAM beams we suggest you examine
the product and advise your supplier in writting within 48
hours if there is any inconsistency to your order.
Natural timber features and variations in colour and texture
of the wood and/or laminates are not considered defects.
Handling / Transport
Your DGI GLULAM beams should only be top loaded and a suitable
protective packaging should be used to avoid damage to the
face or edges by chains, ropes or slings.
Care should be taken when lifting to avoid damage and that
undue stresses do not occur. Spreader bars should be used on
lifting equipment, particularly when handling long slender
DGI GLULAM beams should not be dropped, jarred or dragged
during unloading from a truck or at a site. Such treatment
can cause damage to the surface and possible splitting and
On recept of your DGI GLULAM beams it is essential that they
are to be stored in a way that they are protected from the
weather and from areas that are subject to extreme changes
DGI GLULAM beams are made using exterior glue, but still retain
the physical characteristics of the parent timber and consequently,
durability is similar to the species from which they are made.
As with any kiln dried product they should remain fully protected
from the weather until installation has been completed and
the building 'roofed in'.
If you are storing your DGI GLULAM beams in the open prior
to installation, they should be covered with a tarpaulin and
placed flat on gluts 200mm off the ground. When storing beams
on top of each other, spacers should be used to allow air to
circulate. In high humidity situations any plastic wrapping
should be slit to prevent sweating.
PROTECTION DURING CONSTRUCTION
As with storage, DGI GLULAM beams need to be protected from
weather elements during installation and construction.
Regardless of the appearance required, DGI GLULAM beams should
be properly envelope sealed with suitable sealer or paint protector
prior to erection. At least three coats should be applied with
a light sand between coats to remove raised fibres. Particular
attention should be paid to sealing the end grain. Any fresh
cut should immediately be resealed.
During construction they may also be covered with a non transparent
plastic or similar which should be open at the bottom so as
to allow moisture to escape.
If your beams are left without proper protection, natural
weathering may occur: this could include a change of colour
and the opening of small shakes, etc. If appearance quality
is required, then it may necessitate some sanding and filling
prior to final finishing.
Should your beams be exposed permanently or if construction
will take longer than normal (around 6 weeks), then please
contact your supplier or DGI for further advice. If the end
of your beam will be exposed to the weather, such as protruding
through a wall, then an end cap should be used.
With structural members, notching or drilling of holes may
seriously reduce the strength of the beam. Unless the beam
has been specifically designed to allow for such, the practice
should be avoided. Where birdsmouths, cross section reductions
at overhang, or taper cuts are required, please refer to AS1684
or check with DGI or your engineer.
