SUPPORT PROFILES
The graphs below can be used to determine the free span for each type of support (D1 or D2) with or without a reinforcement
profile. This is the maximum length of the support between the hinge profiles in relation to the load and the depth (D) of the roof.
The maximum bending is 1/200. In other words: a bending of 1 cm for a free span of 200 cm. The
load is related to the snow and wind
load.
Practical example:
The axis distance (AX) between the support profiles is 1000 mm (= with plastic sheets with a width of 980 mm). The depth (D) of the
roof is 3500 mm. The support length LD> is > depth D for a roof pitch > 10°. Take this into account.
The prescribed load is 500 N/m2 (~ 50kg/m2). The roof is provided with multi-layer plastic sheets.
Determine the point in the “500 N/m² & 1/200” graph and select a support that is above this point.
The graph now has two options:
You either select support D1 with reinforcement profile V642.
Or you select support D2 without reinforcement that can handle a slightly larger span.
The maximum bending (1/200) with a load is 17.5 mm. Less if unloaded
The maximum support profile length we can supply is 6 m.
