EJOT JZ3 5.3" Solar Fastening System for Metal Purlins
The EJOT JZ3 3.15" below the rubber gammet. About 2" above the rubber gammet. Solar Fastening System engineered
for easy and rapid anchoring into metal substructures, the fastener forms its
own female thread providing a tolerance free connection in substructures of US
steel gage 16 or thicker (= 1.5 mm). Available with standard sealing
element FZD or EJOT ORKAN Storm Washer (on
request). Length variable to suit project.
The stainless steel JZ3's
specialized thread design gives maximum fastening performance in steel
substructures. It can be used with a wall thickness from about 1.5mm (0.059"
/ gauge 16 (USG)
Solar panels are installed in different locations,
depending on space requirements, proximity to the energy usage point and the
availability of solar energy resources.
panel installation points include:
- On the roof of a building
- Top or side of poles firmly planted in the ground
- On the ground and elevated by tilt mounting racks
Regardless of where your solar
panels are installed, the goal is to ensure that they remain safe, secure and
operational for years to come.
- The thread length
(measured from the thread point to the static fixed point) is calculated
to the specifications of your project. It is generated from the
recommended installation depth + profile height + insulation thickness of
- The specified
screw length guarantees the optimum installation depth for every joint.
- The defined
installation depth is an important prerequisite for the preparation of a
project related initial sizing.
- The assembler
cannot change the specified insertion depth. Important performance
features stay constant.
System Benefits for Load & Structures: Avoiding a Weak Link
Often during the planning of a solar installation the
placing of the module stand on the roof is not sufficiently examined and the
importance of the placement is underestimated.
The fastening system can become the weak link in the
chain if the actual loads, such as the weight of the complete solar
installation and wind force cannot be absorbed with a certain safety margin.
The system must also guarantee a lasting seal between roof penetration and
fastener. If this link between solar installation and roof is not chosen
correctly, it can lead to expensive problems with the solar roof.
EJOT Building Fasteners have developed the "EJOT
Solar Fastening System", for joining the mounting rack for solar units and
the roof. The Solar Fastening System is directly and securely fastened onto the
substructure in a quick, easy and reliable way. The direct load transfer into
the substructure is very important, in order to permanently and reliably absorb
linear expansion due to temperature, wind and snow loads.
