Speedwall panels
Speedwall panels are rollformed from zinc coated steel
strips. The steel from which the shells are manufactured
conforms to AS1397:2001.
Steel shells have a base metal thickness of 0.4mm B.M.T. with
a Z275 zinc coating. These panels have an aerated concrete
core and weigh nominally 10.2kg per lineal metre.
Loading combinations
All loading combinations are in accordance with NZ4203:1992
and AS/NZS 1170.0:2002.
General design notes
The designs specified in this manual have been carried out in
accordance with NZS4203 and laboratory testing carried out
by BRANZ Limited.
The tables and charts are prepared for the use of Speedwall
in wall applications i.e. floor systems cannot be modelled
from the safe load tables in this manual.
Interpolation of the tables is acceptable.

New Zealand Building Code (NZBC) compliance
Under normal conditions of dry internal use, Speedwall
systems have a serviceable life in excess of 50 years and
satisfy the requirements of NZBC Clause B2 – Durability.
Speedwall Fire Rated Systems can be used to provide passive
fire protection in accordance with the requirements of NZBC
Clause C3 – Spread of Fire.
In order to satisfy the requirements of NZBC Clause C4 –
Structural Stability during Fire, designers must ensure that
fire rated elements are supported by elements having at least
the same Fire Resistance Rating (FRR). Collapse of elements
having a lesser FRR shall not cause the consequential collapse
of elements required to have a higher FRR.
Quality control
The performance ratings of the published systems have been
obtained by independent testing and opinions sourced from
organisations with accredited quality assurance. It is of prime
importance to pay strict attention to the details of design,
construction and workmanship, otherwise the performance
could be significantly degraded.
Design guidelines
The recommended maximum span for Speedwall Fire Rated
Systems is 4000mm. Greater spans are subject to specific
engineering design.
Limitations
Adhesive fixing cannot replace mechanical fasteners in
Speedwall Fire Rated Systems.
Do not install Speedwall above the span and height limits
stated in this booklet.
Transport, handling, and storage
Generally, lengths of Speedwall are delivered to site by
long trailers and articulated trucks and access to and on
building sites must be adequate to accommodate these types
of vehicles.
Off loading and site storage or craneage onto site is the responsibility of the client and suitable arrangements should
be made prior to delivery.
Speedwall products are packed and protected against damage
during delivery but care must be exercised during unloading.
Lengths must be adequately supported during unloading and
where packs are broken and panels lifted by hand, care must
be taken not to slide or drag the panel and scrape the finished
surfaces of the product.
Where it is necessary for Speedwall Panels to be stored on
site they should be placed away from the building operations,
if possible, in the order in which they will be fixed.
Store Speedwall panels on site flat or in their pallets.
Storage should provide a firm dry base, protected from the
weather, accidental damage and moisture.
The panels should be stored on bearers not more than 2000mm
apart.
Stack heights are limited to 10 pallets.
The Speedwall panels must be stored under clean, dry and
ventilated conditions.
Adequate cover should be provided and water must not be
allowed to lie on the panel surfaces, which will cause staining
and degradation of the surface coatings.
If bundles become wet the panels should without delay be
separated, wiped with a clean cloth and stacked so that the
circulation of air will complete the drying process.
Strippable film
Speedwall panels will generally be coated with a plastic
film to provide protection during handling and transportation.
This film has a very short life when exposed to exterior
conditions and must be removed immediately after installation.
It must not be left lying in the sun or at the site for more than
a few hours. Failure to remove the film will lead to difficulties
later with its removal.
Cleaning
At the completion of the job and at the finish of each days work,
it is essential that the completed area be thoroughly cleaned of
all swarf, rivet stems, nails, drillings and screws, etc, normally
associated with the installation of metal panels.
Hot swarf should not be allowed to contact pre-painted sheet
material. Any grinding, welding or drilling carried out above
the wall level should be done with the panels appropriately
covered to avoid swarf contact.
Failure to do so will result in unsightly staining of the surface
as the metal particles rust or oxidise.
On site handling
Handle units carefully prior to their installation. Avoid knocks,
bumps and scratches, which may lead to maintenance issues
later. Keep Speedwall dry prior to installation.
Installation
Specific design advice should be sought where Speedwall is
to be subject to point loads or other distributed loading other
than wind.
Ensure connection between Speedwall panels are properly
made.
Ensure connections of Speedwall panels to the structure are
adequate.
Maintenance
All cladding products are subject to the cumulative effects of
weather, dust and other deposits. Maintenance regimes are to
be in accordance with maintenance recommendations for New
Zealand Steel Products used for roofing and wall cladding.
