Quality is not only a matter of resisting corrosion during the life time or being colour proof against bleaching. It is also a matter of having a mechanical stable and strong material. During the winter period, wet snow will impact on the gutter hooks with its weight. For avoiding any damages on the roof drainage system, the hooks have to withstand a heavy load.
The Wijo system is the only system on the market with gutter hooks made out of pre-painted high grade sheet steel, folded and pressed together in 4 layers. This makes the hooks exceptionally strong and stable. Together with the shape of gutters and their accessories, the highest requirements according to the standards EN1462 and EN612 are more than well fulfilled.
