Plain Angle Fibre Cement Ridge 45 Deg Pitch (With Copper Fixing) Overall Length - 450mm Cover Length - 430mm Wing Length - 170mm SVK has invested in a state of the art production line for the production of ridges. All SVK ridges are injected in a mould and fully compressed during their production. This production method results in ridges of unsurpassed quality. Strongest ridges: SVK ridges are the strongest ridges on the market. No other ridge comes close to our values concerning bending strength. This is achieved because SVK is the only manufacturer who presses their ridges during production. Because we press our ridges, we achieve a much higher volume mass and bending strength. Very durable SVK ridges are very durable. Because they are pressed, our ridges obtain a much higher density than ridges which are manually manufactured. This high density also largely diminishes the water absorption. The low water absorption rules out that our ridges would deform or suffer frost damage. Quality of the paint coat The quality of the paint coat on our ridges is unequalled. SVK has more than 70 years of experience in preparation and application of paint. This technical ability and the fact that our ridges have a very low water absorption, enables us to produce ridges with an extraordinary UV-resistance and an unequalled adhesion of the paint. Note: Includes copper ridge clips - 1 ridge clip needed for each ridge.
