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.
