Tile Fixing on Thin Metal Purlins Nilson Novello

Currently the most applied system in the fixation of simple trapezoidal metal tiles occurs in low wave. The main advantages of this type of fixation consist of agility in the execution of the project and low cost, however, the disadvantage is the great possibility of rainwater ingress, since water flows preferentially in this region of the tile. In this context, it was developed a new screw that allows the fixation in high wave with the same agility and cost close to the fixation in low wave. This new screw presents greater resistance than the commercial screws, with the advantage of not needing to use shim. Besides the cost reduction for the execution of the projects, it is expected that there will be less possibility of infiltrations.
