Stainless steel gutter refers to the concave part between the two crotch of the building roof. Roof drainage is divided into organized drainage and unorganized drainage (free drainage). Organized drainage generally collects rainwater into the gutter and then drains it down through rainwater pipes. The gutter that collects rainwater is called gutter, and the gutter is divided into inner gutter. And the outer gutter, the inner gutter refers to the gutter inside the outer wall, and the gutter is mostly made of stainless steel, galvanized iron, and asbestos cement.

The most commonly used materials for stainless steel gutters are basically divided into two types: 201 and 304. The thickness is based on at least 1mm or more, and normal 1.2-2mm is sufficient. Too thin and soft, easy to deform and difficult to weld, too thick and not economical. The cost is too high! The material depends on the project requirements, and can be made of galvanized steel, carbon steel, stainless steel and other materials. The best length of stainless steel gutter is 6 meters, which is convenient for transportation and installation.
