Reinforcement of the
fixing of the hinges is provided by 35mm longitudinal steel strips
positioned at the top and the bottom of the panel inner face. These
steel reinforcements between the insulation core and the metal skin
assure durable and long term fixing of intermediate hinges and roller
carriers without the screws to penetrate through the metal sheets’
folds inside the polyurethane foam. Tecsedo only recommends to utilize
15 mm fixing screws. In case of a choice of longer screws by the door
manufacturer/installer, a pilot hole has to be mandatory drilled in
advance. Repeated opening and closing of the door is always assured as
is the excellent long-lasting resistance to weather conditions
TRADITIONAL
PANELS
We just recall that it is important that
center of the hinge has not to be positioned below the upper edge
(first position where the internal steel sheet bends from horizontal)
of the inner face of the bottom panel.

The specific joint
detail complies with European Safety Standard EN 12604 and must be used
on doors less than 2500mm in height. Please note that drawings refer to
nominal dimension of panels, therefore production tolerances of the
actual delivered panels have to be considered for a correct positioning
of the hinges and for a proper articulation of the panels. We recommend
to assemble some trial doors at your own company before shipping doors
to the first customers. Many factors have also to be considered to
judge implications for sufficient clearances for door flashings and
surround:
• Width of the door (e.g.: having residential doors usually an
horizontal positioning of the sections along the ceiling, there is
always a panel warping of some mm for its own weigth, to be reduced
with the utilization of Omega bracing bars, imperative for door span
wider than 4.5 m)
• Number and distance of hinges utilized
• Deformation of the door for heat dilatation (panel bow, depending
upon: a.- Temperature difference between inside and outside
temperature, b.- Orientation of Door, c.- External finish colour)
• Hinges tolerances
• Door settlement after several cycles done
