河北Characteristics and applications of gutter downspouts

With the coming of the plum rain season, it rained heavily. Many customers and friends have asked about the rainwater drainage system of small light steel houses. Today, I will give you a brief introduction to the characteristics and applications of gutter downspouts.

What is a delivery system? Light steel residential rainwater drainage system, also known as roof rainwater drainage system, consists of roof gutter, rainwater pipes and related components, can better collect roof rainwater, reasonable discharge of building rainwater, so as to protect the exterior surface and 

foundation of the house, extend the service life of the building, while completing the roof rainwater drainage, but also has a beautiful decorative effect.

　　The roof of the traditional building in China is scattered water, and the rainwater drains directly into the ground through the tiles. After a long time of development and improvement, the water drop system has gradually evolved from the traditional semi-circle to K-shaped, square and even decorative drains. In Europe and the western United States, Tuscany in southern Italy, Provence in southern France, and southern California in the United States, semi-circular drains are used together with circular downspouts. In the eastern and central United States, people in this region prefer K-shaped drains with square downspouts. Other regions, such as Australia and Japan, have different aspirations for housing systems. They like semi-circular gutters that are high at the front and low at the back.

Comparison of gutter downspouts and materials

1. Aluminum alloy material

Moderate price, good performance, a wide range of applications, such as villas, apartments, multi-storey and public buildings;

2. Copper material

High price, good performance, often used in villas;

3. Color steel material

Corrosion resistance, long service life, widely used in industrial plants;

4. Titanium zinc plate material

Good elongation and tensile strength, mainly used in metal roofs, apartments, etc.

5.PVC material

The price is very low. It is often used in the low-rise drainage system of ordinary residential buildings in rural and third-tier cities. PVC material has severe thermal expansion and cold shrinkage, resulting in water leakage at the gutter joints. And the color is single, basically only white, and the appearance of the house is not coordinated.

Gutter downspout has good resistance to ultraviolet, weather resistance, oxidation resistance, corrosion resistance and wall pollution. The commonly used fall system accessories are quite complete. It has good load-bearing and drainage functions, various surface treatments and good decorative effects. The structure of the drainage system includes cornice, cornice, sealing plate, cornice connector (a K-shaped cornice is not allowed; a half-round cornice is required; otherwise, the cornice will be deformed), internal and external angles, hangers, supports, and downcomers. Grooved pipe fittings, downspouts, elbows, inclined Gutter downspout has good resistance to ultraviolet, weather resistance, oxidation resistance, corrosion resistance and wall pollution.
