Despite having most of
the features needed to make a proper window, uPVC profile bars alone do not
have enough stiffness and stability for this application! But steel reinforcement
has been a very efficient solution for that!
Before welding the
profiles, a reinforcement profile is installed in the inner chamber of each vinyl
profile. This steel reinforcement, increases performance of the product to
compensate temperature changes and prevents deformation in the shape of window
or doors. The reinforcement profiles often are made of
steel and their shape and sizes are based on the design of the inner chamber of
the PVC profiles.
Screwdrivers and screw centers
are used to install reinforcement profiles by screwing them to the uPVC
