Technical Specification
Roof systems incorporating keder profile on top of the truss grid base structure are very popular among professional installers, riggers and event companies as they are mostly used in large events covering the main stages of cultural and public events. The big advantage of keder roof lies in the possibility to cover big size stages and at the same time maintain high loading capacity. The keder profile roof top structures allow to use higher number of relatively small PVC top cover stripes to be used and handle the most of the weather conditions that may occur during the event.
The main rectangular grid of Keder Roof 14 x 10 x 9 m is made of TT74 truss and the main horizontal support for the keder profile rafters supporting the canopy stripes is from TT54 truss series.
TAF standard keder roof covers stage of 14 x 10 m (46 ft x 33 ft) in size and the event equipment can be lifted up to the 9 m (29.5 ft) in height thanks to the employment of Tower 2 truss columns. Maximum loading capacity of the roof is 5000 kg (11 023 lbs). The operational wind limit for using the roof system with the side canopies on all three sides is 20 m/s (45 mph).

Used Truss
Main Grid
TT74 truss - rectangular truss with 520 x 760 mm (20.47 in x 29.92 in) outside dimensions, main pipe Ø 50 x 4 mm (2 in x 0.16 in), braces 30 x 3 mm (1.2 in x 0.12 in). The alloy used as material for the pipes is EN AW-6082 T6.
TT54 truss - box truss with 520 x 520 mm (20.47 in x 20.47 in) outside dimensions, main pipe 50 x 4 mm (2 in x 0.16 in), braces Ø 30 x 3 mm (1.2 in x 0.12 in). The alloy used as material for the pipes is EN AW-6082 T6.
Rafters
Keder profiles
Columns
Tower 2 - TT44 truss, steel base plate, long outriggers, top section and sleeve block
Wind Management
Wind resistence is calculated with 3 side mesh canopies applied to the structure (2 side canopies and one rear canopy). The three roof walls carrying canopies must be secured by guy wire cross bracing at all times as well as the top grid horizontal ceiling.
Side walls guy wires min. loading capacity - 3540 kg (7804 lbs)
Rear walls guy wires min. loading capacity - 5100 kg (11,244 lbs)
Roof ceiling guy wires min. loading capacity - 2300 kg (5071 lbs)
Please note that tension capacity of guy wires needs to be higher than required min. loading capacity.
In service max. allowed windspeed - 20 m/s - 72 km/h - 45 mph
Ballast
Option 1 - 6000 kg / 13,228 lbs ballast underneath each tower base = total of 24 000 kg / 52,911 lbs ballast necessary
Canopy and Side Walls
Top canopy is available standardly in silver grey and black color. The material used is SIO-LINE B 8000 with weight of 630 g/m2.
The side walls are covered by air permeable mesh canopies in black.
Transportation Data
Total weight: ca. 5150 kg ( 11354 lbs)
Transport volume: cca.59m3 / 2084 cu ft
All truss segments are packed in brown carton boxes for better handling and protection during transport.
