Heavy duty Grating

Insertion type grates

As an alternative to our detailed pressed grating program (with a maximum bearing bar height of 150mm and 5mm thickness) we are offering our insertion type grates for extreme loads. These grates are capable of withstanding loads such as those of airplanes, dredgers and excavators and caterpillar or tracklaying vehicles.
