Modern water waste systems differ by three main criteria: material, form, size.
In a form the drain can be rectangular or round. By the size, diameter of drainpipes varies from 50 to 160 mm, and diameter of trenches - from 70 to 200 mm. The more it is capable to pass the drain section, the more water. When calculating the optimum size the roof area, its inclination, and also number of points of a drain of water is considered.
On material the most widespread types of water waste systems are metal drains from galvanized steel with a polymeric covering.
- for a roof of 30 m ² makes 80 mm,
- for a roof of 50 m ² - 90 mm,
- for a roof of 125 m ² - 100 mm.
Metal drains are made from goryacheotsinkovanny steel with a bilateral polymeric covering (plastizol or purat). Steel drains in operation differ in durability, durability, resistance to chemical, natural adverse effects, corrosion. Metal water waste systems perfectly will be suitable for a roof from a metal tile, a professional flooring and a fold. It is caused by the fact that metal roofs more others are exposed to a mass descent of snow. Therefore to secure the roof during sharp warming, in addition it is necessary to take care of such elements of safety of a roof as snegozaderzhatel.Our enterprise makes the equipment for production of a trench of various width. In this line the electronic control system (ChPU) is used.
