Yichun Circular Greening Plastic Drainage Pipe Manufacturer, Football Field Drainage Pipe, Greening Plastic Drainage Channels, Permeable Plastic Drainage Pipe
Plastic drainage channels are composed of a plastic core body.
Outer packaging filter fabric assembly. The plastic core is made primarily from thermoplastic synthetic resin, modified and extruded into fine plastic filaments in a molten state through a nozzle. The extruded filaments are then fused at junction points by a molding device, indicating the outer diameter (mm) of the core.
If rectangular, it features high surface aperture rate, good water collection, high porosity, excellent drainage, strong compressive resistance, good pressure resistance, flexibility, adaptability to soil deformation, durability, light weight, ease of construction, significantly reduced labor intensity for workers, and high construction efficiency, hence it is widely welcomed by engineering departments and extensively applied. The naming of plastic drainage underdrains is divided into four parts: the first part is the code SM; the second part indicates the shape of the underdrain, with Y for circular and J for rectangular; the third part is the external dimensions of the underdrain.
If circular, it indicates the cross-sectional dimensions of the core (width x thickness, mm); the fourth part represents the product's structure. When marked with 'K', the product is hollow (single hole); marked with 'D', it indicates a multi-hole design, with the number before 'D' indicating the number of holes. For example: A circular plastic drain grating has an outer diameter of 100mm and is hollow with a single hole, and is designated as SMY100K. A rectangular plastic drain grating has a cross-sectional width of 150mm and a thickness of 50mm, also with a single hole, and is designated as SMJ150 x 50K. It forms a three-dimensional, three-dimensional network structure. The plastic core comes in various structures such as rectangular, hollow matrix, circular hollow circular, and more. This material overcomes the drawbacks of traditional drain grates.
