The number of fasteners used on a roof depends on the wind zone in which the building is located, the angle of the roof, the position of the tile in the slope, the height of the building or the type of tile.Roof tile fasteners and ridge clamps Corotop® are made of steel wire with anticorrosion coating (fasteners) and aluminum sheet (clamps). Different shapes and colours make it easy to match the roofing.
