| The
challenge in the aerospace industry is to provide doors that can
be designed to be very narrow and tall and which will better withstand
the extremely high or hurricane force wind conditions. Typically,
doors for aerospace installations must be very light weight and
must be manufactured to exceptionally high standards, due to the
fact that they are used in rocket assembly and payload encapsulation
environments. Additionally, many installations require craneway
openings, and may need to be controlled from various locations in
the vertical integration facility as the controller must see the
door movement from different locations in the tower. And, even though
the doors are not opened very frequently, they must always provide
consistent reliability due to the critical need for the doors to
be opened as an integral part of the production/launch process.
