Door is made of aluminum material. Transparent window can be
adopted as an option.
Transparent window is made of polycarbonate material, which is
quite excellent in wind pressure resistance. The space between
slates of door consists of rubber seal finishing to prevent dust or
harmful insect and interrupt any noise during operation.
In addition, when slate is damaged, it is easy to replace it into
new slate by simply opening the cover and unfastening the
bolts.
