The gutter refers to the concave part between the two hips of the building roof. Roof drainage is divided into organized drainage and unorganized drainage. Free drainage and organized drainage generally collect rainwater into the gutter and then drain it through the rainwater pipe. The ditch that collects rainwater is called a gutter. Gutters are divided into inner gutter and outer gutter. Gutter, inner gutter refers to the gutter within the outer wall, usually with a parapet. External gutter is the gutter that sticks out of the outer wall, usually without a parapet. Gutters are mostly made of tinplate or asbestos cement.
