At the installation stage of the building’s floor, the project of an inlet under POLMAR SYSTEM can be considered. In this case we can use an additional support system, which will increase the space for dirt accumulation by several times. However, we must remember that these supports reduce the loading capacity of the grates.
This type of installation is made by use of an inlet frame and a frame which protect floor against being damaged. Both elements are made individually according to ordered cleaning surface.
