Safe and durable snow guards with oval tubes for regular shingles roofs and exposed metal roofs (metal tiles, straight rib panels and metal shingles). Because of the oval shape of the snow barrier tube, the tube is stronger and can withstand a higher snow load.

SNOW GUARDS CALCULATION
- Even distribution of snow load over the roof
- Protection against snow falling along the entire length of the roof
The maximum distance between the brackets of snow guards is 1.2 m.
Snow guards withstand a snow load of 500 kg/m (5 kN/m), each bracket can withstand a load of 300 kg (based on static tests according to Swedish standard SS 831367).
Snow retention system is installed above the load-bearing wall or higher. When installing snow retention close to the eaves, it is important to make sure that the structure can withstand the possible load.
The roof slope is 1:1,5 (~33°)
Installation of one row of snow guards, if the distance from the snow guard to the ridge does not exceed 6.8 m
If the roof slope is longer, a second row of snow guards is installed at the level of half the slope length, but not more than 6.8 m between the lines of snow retention system.
Snow guards are manufactured according to SS 831335: 2014 and are tested with a snow load of 5 kN/m
If the actual snow load on the roof exceeds the calculated values, you should additionally remove the excessive snow.
