Load graphs for roofs with plastic sheets
GUTTER PROFILES
The graphs below can be used to determine the free span for each type of gutter (support). This is the distance (P) between the
supports (posts) in relation to the load and the depth (D) of the roof. The maximum bending is 1/200. The
load is related to the
snow and wind load.
Practical example:
The roof has a width (B) of 5300 m and a depth (D) of 3500 mm. 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 gutter (support) that is above this point.
The graph now has two options:
Either you select gutter support GD2 that will make allowances for a free span of 5300 mm.
Or you select gutter support GD1 that will make allowances for a free span of 2700 mm. You then install an extra post in the
middle for support.
The span is the distance (P) between the posts. In this example, the width can be 5500 mm where the free span (P) between the
posts = 5500 – 2 x 100 = 5300 mm.
The bending in the middle with a load of 500 N/m² is 1/200 or 5300/200 = 26.5 mm. Less if unloaded
The maximum gutter profile length we can supply is 7 m.
