years, <strong>Tru</strong>-Fold is your only solution. <strong>Tru</strong>-Fold is available up to 10m high and 30m wide in one<br />
door, totally eliminating the need for centre mullions and multiple doors for your wide door solutions.<br />
Standard colour steel cladding gives a quality pre-finish exterior with the main frame constructed<br />
from zinc coated steel. Applications for your <strong>Tru</strong>-Fold have been used in airport hangars, schools,<br />
workshops, factories, government departments, supermarkets and industrial buildings.<br />

Frame construction on all <strong>Tru</strong>-Fold doors<br />
are from galvanised steel. All construction<br />
is from experienced engineers taking pride<br />
in their work. With both quality steel and<br />
workmanship, <strong>Tru</strong>-Fold doors will outlast any<br />
door on the market.<br />
Don’t watch your step as there are no floor<br />
tracks as on sliding doors. This gives excellent<br />
transition as there is nothing to trip over or<br />
drive over. Excellent in industrial or hangar<br />
applications.<br />
No horizontal, internal tracks. As seen in the<br />
photo, making the internal finish very tidy<br />
when your door is shut.<br />
Ease of operation is achieved by the doors<br />
being counter-weighed. If the door weighs<br />
1000kg. 1000kg of weights are used making<br />
this the easiest door on the market to operate.<br />
Hand chain unit can be added to any door. This<br />
can be mounted on either side of the door.<br />
Motor operation gives you total control of<br />
your door. With a built-in emergency over-ride,<br />
you will never be left “in the dark.” Motor can<br />
be mounted on either side of door. Motor units<br />
come standard with remote activation.<br />

Cladding Options<br />
Cladding options for <strong>Tru</strong>-Fold doors are endless. 90% of doors are clad with a roofing profile due to<br />
cost and ease of installation. Shown are some of the many completed projects. Weight and thickness<br />
can be an issue, but submit your ideas and we will work with you. Horizontal cladding can add extra<br />
costs.<br />

“Half Glazed, Half Coloursteel”
Single Spans<br />
<strong>Tru</strong>-Fold doors add no weight to the lintel, no tracks to the floor and no wing walls to the outside<br />
edge of your building. The over all door is easy to install and very easy to operate. A large single<br />
span door can be opened manually or with a motor option. The example below is based on a door<br />
estimated at 600kg.<br />

Sliding doors need wing walls, therefore the hangers<br />
take up extra space. Hangers can’t be close together,<br />

Construction<br />
<strong>Tru</strong>-Fold construction surpasses every other type of door on the market. All the doors are made to<br />
withstand a minimum of 0.85kpa and can also be constructed to meet any wind load. Shown in the<br />
photos below are the two most common types of truss configuration, lattice and purlin. The type of<br />
truss used on each door is determined on door width and cladding.<br />
“Lattice Type <strong>Tru</strong>ss”<br />
“Purlin Type <strong>Tru</strong>ss”

Shown is a project with a row of hangars at a small airfield. There is also another lot of hangars on the<br />
back of these three. On a building 15.0m wide, the 13.0m wide door allows you to have a man door<br />
next to <strong>Tru</strong>-Fold door as seen in the photos below. The doors are manually operated.<br />

Shown is a large door in the coal mining industry. The site is at 1000m above sea level and faces<br />
huge winds. The door was retro fitted to an existing building and has been a huge success. Other<br />
types of doors have been blown in, but the <strong>Tru</strong>-Fold door has come out on top. A motor fitted,<br />
makes it 100% operator friendly.<br />

Subject: BI FOLD DOOR STOCKTON MINE.<br />
T0 WHOM IT MAY CONCERN<br />
In November 2006 Solid Energy, Stockton Mine, Northern Buller engaged Egmont<br />
Doors Ltd to design, build and install a bi folding door for one of its Opencast Mine<br />
workshops. We understand that this door was fabricated by <strong>Tru</strong>-<strong>Bilt</strong> <strong>Industries</strong>,<br />
Dunedin.<br />
The existing door opening measured approximately 10m by 9.5m. The Stockton Mine<br />
is situated 1000 metres above sea level. The climatic conditions experienced at this<br />
site are extreme. Annual rainfall is over 6 metres, snow ground cover up to 600mm<br />
can be expected at any time, and strong winds in the 100kmph range are common.<br />
The new bi fold door is exposed to all these conditions.<br />
Solid Energy is very pleased with the performance of this door, as are the workshop<br />
occupiers, our major stripping contractor, Doug Hood Mining Ltd.<br />
The door was manufactured, delivered and installed all within the contract timeframe.<br />
Regular contact has been maintained by the installer as to the doors performance.<br />
If installing another similar size door, I would have no hesitation in using this product<br />
again.<br />
Finally, I am happy to be contacted to provide any further information if required.<br />

Helicopter Maintenance<br />
Shown is a huge door for a helicopter maintenance company. Glass on the top 3/4 gives excellent<br />
natural light into the workshop offering an excellent working environment. With a trackless floor, the<br />
conveyance of helicopters for test flights becomes effortless. With the simple push of a button, the<br />
huge 132m 2 door quietly lifts up out of the way.<br />

Workshop Door<br />
Shown is a <strong>Tru</strong>-Fold on a new tyre retailer. There were two doors with the front door having glazing<br />
to the bottom panel only. This gives the benefit of excellent lighting with protection from wind and<br />
rain. (Note - horizontal cladding may add additional costs)<br />
4.0m high x 10.0m wide
Transport/Freight<br />
Every <strong>Tru</strong>-Fold door is packaged in the best possible way for ease of freight and to minimise<br />
damage. From small doors to large doors they are all able to be transported using standard trucks<br />
and containers. In most cases there are two pallets. One the same length as the tracks with all the<br />
tracks, counter weights etc and one with the trusses or purlins.<br />
Small doors ready for transport<br />
Installation<br />
Installation is very important with the <strong>Tru</strong>-Fold door. A good product can very quickly become a<br />
headache product due to poor installation. The procedure is much the same on all doors regardless<br />
of the size and can easily be undertaken by knowledgeable tradesman. The crane below is lifting the<br />
door into position with the top part clad already. All doors have installation instructions provided and<br />
we also offer on-site assistance, to first time installers.<br />
