The screw support is a metal tube Ø 57 or 76 mm with a flange and several blades spaced relative to each other.
Specially designed configuration of the support blades allows easy working in the ground (screw in/out). The cylindrical structure with a diameter equal to the blade diameter simulates a monolithic concrete foundation up to Ø 300 mm.
During the operation of the foundation, the blades redistribute the compression or extrusion force vertically and ensure a high load-bearing capacity of the screw support.
This effect allows the screw supports to be used on any type of soil (except rocky soil).
The supports are galvanised and coated with polymer material.
