Hydraulics and Classification

Hydraulic average calculations

BG-FA facade channel (strand length = 20 m)
Type RB 130 RB 230
hight in mm 55 70 110 55 70 110
Qmax (l/s) 0,6 0,9 3,6 1,2 1,8 6,7
precipitation (l/s ha) max. permissible surface (m²)
150 40 60 240 80 120 450
200 30 45 180 65 90 340
250 25 35 140 50 70 270
300 20 30 120 40 60 225
350 17 25 100 35 50 190
400 15 22 90 30 45 165
COMMENT: This average calculation is based on not perforated BG-FA facade channels on a strand length of 20 linear metres and free runout. We will be pleased to draft an exact hydraulic calculation adapted to local conditions at any time.

BG-PA car park channel (strand length = 10 m)
nominal width 100 150 200
hight in mm 55 55 55
Qmax (l/s) 0,6 0,9 1,2
COMMENT: This average calculation is based on BG-PA car park channels on a strand length of 10 linear metres and free runout. We will be pleased to draft an exact hydraulic calculation adapted to local conditions at any time.

Classification according to weight capacity

load classes test load area of application acc. to EN 1433
A 15 15 kN Traffic areas which are only used by pedestrians and cyclists and similar areas, such as green spaces.
B 125 125 kN Pavements, pedestrian areas and similar areas, car parks and parking decks.
C 250 250 kN Only applies to attachments/drainage channels in the peripheral channel area, which may extend 0,5 m into the carriageway and 0,2 m into the pavement measured from the kerbside, and for road verges.
D 400 400 kN Carriageways of roads  (including pedestrian zones), road verges, car parks and similar hard-surfaced thoroughfares.
