For consistent load distribution when fastened onto the crown of a trapezoidal metal panel.

ORKAN Storm Washers advantages

The use of a purpose-designed sealing element is vital to ensuring a weather-tight roof.

 • Consistent load distribution when fastened onto the crown of a trapezoidal metal panel. The double corrugation on top of the washer guarantees high form stability and equal load transmission. 

• A buffer for the fixed distance between substructure and screw head.

• The closed-cell EPDM rubber foam on the back of the washer compensates tolerances, since the crown of many trapezoidal metal panel profiles is slightly convex or concave-shaped. There is no “bridging” therefore moisture cannot reach the fastener’s shank and consequently the interior of the building.

• Minimal compression is required for permanent watertightness. Thus, the “deformation” of the metal roof crown is easily avoided during the installation process. 

• A more secure installation because the installer consistently penetrates the middle of the crown without damaging/ scratching the roof surface.  

• A higher initial torque can be applied without deforming the crown. 

• International test reports document increased load values through application of ORKAN Storm Washers on aluminum trapezoidal metal profile roof panels.
