Calculation of short snow guards

A snow guard that only covers a short part of the length of the building, e.g. over a door, runs a considerable risk of being overloaded. We have developed a calculation in order to safeguard the function. Enter your details below to ascertain whether it will hold. To achieve a stronger snow guard, the distance between the brackets can be reduced (max. 1200 mm – min. 600 mm).

Form

Roof type: --- select --- Saddle roof Pentroof Specify the snow load basic value (find your snow zone): kN/m² Specify roof gradient (a): degrees Specify the length of the roof drop (y): m Longest distance from gable to outer bracket (x): m Specify c/c brackets (cc): m Max. overhang on snow guard beyond outer bracket (z): m Max. load on bracket: 6 kN According to EN 1991-1-3:2003 5.3.2 (2) The values in table 5.2 apply to snow that is not prevented from sliding off the roof.	°a mz my mcc mx = Calculation surface for load on outer bracket etc. on short snow rail.
