1.0 General Information
1.1. Introduction
Gamma Bracing system technology has been specifically
designed and rigorously tested in New Zealand to
provide structural bracing for both residential and light
commercial buildings within the scope and limitations of
NZS3604:2011.
The Gamma Bracing System has been tested in
accordance with the New Zealand Building Code,
verification method B1/VM p21 {2010} racking test limited
states design; cited in NZS3604 Timber Framed Buildings
to determine wind and earthquake ratings of bracing
elements. This aligns with the new loadings standard
AS/NZS 1170.
CodeMark Certification
Having met New Zealand’s stringent standards, the
Gamma Bracing system is the future solution for wall
bracing requirements within timber framed buildings.
1.2. Warranty
The Gamma Bracing system carries the following warranty.
This warranty is given by Gamma Bracing Technology Ltd
(“The Manufacturer”)
The manufacturer warrants that the products produced
by the manufacturer shall be free of defects in materials
and manufacture. If the products produced by the
manufacturer do not meet the manufacturers standards,
they will replace with the equivalent product. The
manufacturer advises that only products, components and
systems recommended by Gamma Bracing Technologies
Ltd be used. At all times these must be used in accordance
with the relevant product manufacturers usage
recommendations.
If this is not done, the manufacturer will need to be
satisfied that any defect in it’s product is attributable
to the failure of the manufactured product to meet the
manufacturers standard (and not another clause) before
this warranty applies. This warranty excludes all other
warranties and liability for damage or loss in connection
with the defects in the manufacturers product other than
those imposed by legislation.
1.3. Benefits of using Gamma Bracing System
The design of the Gamma Bracing system allows for
easy installation for both new and existing buildings. No
additional, specialty bracing linings are required other than
to provide standard interior finishings.
Once the Gamma Bracing system has been installed, the
bracing requirements of the building are completed and
therefore the need for temporary timber bracing
is significantly reduced; saving time and cost as well as
providing a safer working environment.
Inspection by the Building Consent Authority of the
bracing system can be done early in the construction
programme. No further inspections of bracing elements
are required, thus another saving of time and money.
Using the Gamma Bracing System removes the need for
other types of bracing such as galvanised straps, which
connect the stud with the bottom plate. By removing the
need for these straps a flatter surface is provided for the
installation of the interior lining.
Provided the timber frame moisture levels, as detailed
in NZS3604:2011 and NZS3602; are followed and the
Gamma Bracing system is used in a closed environment,
the Gamma Bracing frames once installed do not require
maintenance. Provided the requirements of NZ Steel’s
GalvsteelTM (Axxis 550) Durability Statement are met,
the Gamma Bracing frames are unaffected by weather
conditions.
Gamma Bracing frames are provided with a warning label
advising that the structural integrity of the building must
be maintained at all times. This is to prevent the possible
removal or modification of the Gamma Bracing system
during renovation work.
Each Gamma Bracing frame provides significant bracing
values for both wind and earthquake demand. Total
bracing integrity can be achieved wherever Gamma
Bracing frames are positioned throughout the buildings
structure.
