In order to drain the storm water flowing down the roof surface, this flashing is installed at the bottom of the roof surface and the top of the wall surface.
It is divided into a general gutter fixed by a gutter bracket and an attached gutter fixed at the end of a roof panel.
Depending on the amount of roof panel used, floors can be prevented from flooding by adjusting the floor and height of the gutter.
To match the color of the panel, the iron plate may be made of color coil or stainless steel may be used to delay long-term corrosion caused by moisture.
