PVC Siphonic Roof Drain ensuring long-term durability against harsh weather conditions and chemical exposure. With a diameter specification of 110 millimeters and each carton containing 12 units, it is ideal for various building projects requiring effective roof drainage solutions.
The key advantage of the siphonic roof drainage system lies in its highly efficient water discharge capability. By utilizing the unique siphon principle, this drain pipe can rapidly remove large volumes of rainwater in a short period, effectively preventing roof water accumulation and reducing the risk of structural damage and safety hazards. Additionally, the lightweight design of the PVC material simplifies installation, making it easier and more cost-effective to implement.
In terms of appearance, the drain pipe features a sleek and streamlined design with a smooth surface free of visible defects, enhancing overall aesthetics while also facilitating easy cleaning and maintenance. Its internal structure is meticulously engineered to ensure smooth water flow and minimize the risk of blockages.
