Firstly, let's examine the components of an siphon rainhead, which typically includes: a leaf guard/anti-turbulent device, the body, and mounting plate, etc. The material of the body can be: cast iron, aluminum alloy, stainless steel, high-density polyethylene (HDPE), polypropylene (PP), and so on. Before installation, it should be based on the position, shape, specifications, and dimensions of the body as designed by the system, and proper pre-allocation work should be done in conjunction with civil construction. Steel gutters can be directly drilled using plasma or other effective cutting methods. If a composite roof material is encountered and it is directly installed on the roof, the roof material must be pre-fabricated in the factory, and drilling holes on-site will damage its structure. In this case, the design unit must provide the supplier of the roof material with specific information, including the number and position of the roof bodies, their shapes, specifications, and dimensions.
