Approved roofing screw throughout Europe
The only painted roofing screw approved for outdoor use
The design and manufacture of the KINGI® roofing screw start from the laws, regulations, requirements and guidelines that apply to this product. Anyone choosing a KINGI® roofing screw can be confident the choice is safe and compliant.
The KINGI® roofing screw is the only painted carbon steel screw to have been granted ETA approval (ETA-25/0267) for climate exposure classes C1–C4. It has been tested to withstand the demanding C4 class, as shown in the HAMK statement (PDF, opens in a new tab). This means Kingi is suitable for use practically anywhere in Finland.
